Having planted a gooseberry in our garden, we need to be able not only to properly care for and propagate it, but also to closely monitor its health. After all gooseberry disease can significantly reduce the yield of our favorite berries, or even lead to the death of the plant.
It should be noted that gooseberry bushes they suffer mainly from the same diseases as currants, but unlike the latter, the degree of damage is much stronger and the rate of spread of diseases is faster.
Therefore, it is very important for us to catch the first signs of the disease in time and take the necessary measures. You can, of course, try to plant in your garden only those new varieties that are resistant to diseases, and ruthlessly get rid of the old ones.
But, firstly, each of us has our own favorite variety, which is simply impossible to part with and worth fighting for, secondly, probably, there are still no such ideal gooseberry varieties that would not hurt at all.
Therefore, we should not relax, but it is necessary to carefully monitor the condition of the bushes of our northern grapes.
After all, the sooner we notice the first signs of disease, the more quickly we will help the plant to cope with them. Moreover, in this case it will be sufficient to apply only folk methods, excluding chemical preparations.
Gooseberry most affected by the following diseases: American powdery mildew (spherotek), septorioza (white spot), anthracnose, goblet rust, mosaic.
As you can see misfortunes on our gooseberries missing. And before we take a closer look at each of them, let's talk about prevention.
Prevention and prevention again
Undoubtedly, we all know the golden rule: it is much easier to prevent a disease than to treat it later.
This rule can certainly be applied to plants, and their protection from pests should also be started with prevention. What preventive measures we can take:
- strict adherence to the rules of agrotechnics when growing gooseberry,
- we try to prevent thickening of the bushes and timely cut out excess, damaged and dry branches,
- we collect and remove fallen leaves, and then burn them,
- dig the soil under the plant,
- We plant plants near the gooseberry bushes that scare off pests - marigolds, chrysanthemums, dill, garlic and others,
- in early spring, it is possible to pour boiling water over the bushes, thus destroying the spores of fungal diseases that have appeared,
- do not forget about regular nutrition, which greatly strengthens the plant immunity,
- also well improves immunity spraying spring gooseberry bushes with zircon solution.
American powdery mildew
Symptoms This fungal disease is a real plague for gooseberries, and not only for it, because currants and other plants also suffer from it.
The first symptoms of this scourge can appear in the spring immediately after flowering. Young shoots and leaves begin to be covered with a white, loose patina, which at first is well erased.
Then he gradually goes to the ovary, berries, covering an increasing area of them. With each passing day, the raid is becoming more and more compacted and, in the end, it begins to resemble brown or dark brown felt.
Damaged shoots begin to bend, cease to fully develop, and often dry out altogether. The leaves curl, become brittle, and the berries covered with this bloom, stop growing, often crack and quickly crumble.
And if we do not start treatment, the affected gooseberry bushes can die within two or three years.
Moreover, the spores of this harmful fungus spread by the wind, infecting more and more new plants. They are not afraid of any frost, they feel great in the winter on fallen leaves and infected shoots, and high summer temperatures.
That is why the fight against this insidious disease must be waged throughout the season - from early spring to late autumn.
Control measures. There are quite a few ways to combat this common disease. I want to recommend some of them to me, as it seems to me the most effective:
1. Early spring pouring of boiling water over the gooseberry bushes partially destroys the spores of the fungus.
2. Then you can treat the gooseberry and the soil around it with a 3% Bordeaux mixture or a solution of soda ash (50 g soda per 10 liters of water), adding soap to it, for better adhesion of the solution. This spraying is desirable to hold before blooming buds on the gooseberry.
3. It is also good to spray the bushes with infusion of wood ash (300 g per 10 liters of water), and also to add ash to the tree trunks, evenly distributing it and mixing it with the ground.
4. The bacterial method of combating this insidious disease also gives very good results. To do this, take 1 part of the infusion of mullein or rotted manure, diluted in 3 parts of water and insist for three days. Then we dilute the infusion three times with water and filter.
You can also make infusions of rotted hay or hay rot, greenhouse earth or forest litter. The effectiveness of these infusions lies in the fact that the bacteria breeding in them, hitting the gooseberry bushes begin to eat mycelium with pleasure.
It is advisable to carry out the treatment with these infusions three times per season: we sprinkle the first time before flowering, the second time right after it and the third time we carry out the treatment before the leaf fall.
5. Another interesting method is to make such a solution: dilute 1 liter of serum in ten liters of water and add 15-20 drops of iodine. This solution can be sprayed bushes throughout the season every 10 days.
6. When cutting off stepchildren on tomatoes, do not throw them away. They will also help us overcome powdery mildew. Insist tomato tops, then add 40-50 g of household soap to the infusion and spray it with gooseberry bushes. And at the end of the summer, when we are already starting to pick up the stems of tomatoes, we can impose gooseberries on them for the winter. Such a popular method is guaranteed to save from pests and powdery mildew.
7. In the autumn, it is necessary to carefully prune the affected plants, removing the affected ends of the shoots without any pity, gather the fallen leaves and burn them all at once, not postponing the matter until later, as powdery mildew spores quickly.
8. If the disease is already running, then in order to avoid spreading it throughout the garden, it is simply necessary to apply chemical remedies. These are such drugs as: "Topaz", "Oxy", "Fitosporin" and others. At the same time strictly follow the dose recommended in the instructions for use.
Symptoms. Anthracnose is another disease caused by fungi that primarily affects gooseberry leaves.
At the beginning small, blurry dark brown spots appear on the leaves. In the course of the development of the disease, the spots merge, the leaves dry and almost all fall prematurely. Only three or four leaves remain on the tops of growing shoots.
In bushes affected by anthracnose, the growth of young shoots is significantly reduced, the sugar content of berries is reduced, and there is no longer enough to rely on a good harvest.
Control measures. First of all, it is necessary to collect all the fallen leaves, since it is in them that the fungus remains for the winter. Leaves immediately burned.
In early spring, check whether there is no untidy leaves under the bushes. When the disease is just beginning, we cut off the affected leaves and spray the gooseberry bushes with a solution of copper sulfate (40 g per 10 liters of water).
In case of dangerous development of the disease, it is necessary to treat the gooseberry bushes with 1% Bordeaux liquid at least four times. Spray - before flowering, immediately after it, then 12-14 days after the second spraying and the last time we process the gooseberry immediately after harvest.
White spot or septoria
1- affected escape of currant, 2- affected leaf, 3- drying of leaves due to severe damage, 4-pyrcidia and conidia, 5 - perithetium, bags with ascospores
Symptoms In this disease, leaves are also affected, on which a large number of roundish spots of grayish color with a dark border appear. A little later dark spots appear on the spots, and they contain spores of the causative agent of septoria.
Gooseberry leaves begin to curl, dry out and fall prematurely. After some time, the bushes are left completely without leaves.
Control measures. We fight with white spot in the same way as with anthracnose, namely: we collect and destroy leaves (in autumn or early spring), at the initial stage we cut off the diseased leaves, loosen the soil under the bushes.
We can also increase the resistance of the gooseberry to septorioz by introducing manganese sulphate, copper, boron and zinc into the soil around the bushes.
1 currant sprout with aeration on leaves and berries, 2 gooseberry sprout with affected leaves and berries, 3 stunted sedge leaf with urediniospores pads, 4 escarpment of sedge with affected leaf, 5-etion and eciospore, 6- urediniospore, 7- teliospore
Symptoms The goblet rust, the causative agent of which is a parasitic fungus, affects the leaves of the gooseberry. First, orange spots begin to appear on the leaves, on which the yellow spore pads are located.
Then they take the form of small goblets. The whole spring and early summer fungus holds on gooseberry bushes. Then the insects and the wind spread his spores to the weeds. It feels particularly good on sedge.
And then all summer the fungus develops on their leaves and winters there.
And in the spring, he returns to the gooseberry bushes, whose leaves, becoming ill, become ugly and fall prematurely. Gooseberry berries also change, become one-sided, their development stops, and then quickly shrink and easily fall off.
Control measures. First of all, try to plant varieties resistant to the disease. When planting, choose higher places on the site so that there is no stagnation of water and on which the sedge does not grow.
Affected plants must be treated with 1% Bordeaux liquid: first - when the leaves bloom, then - after flowering and the last time - 8-10 days after the second.
3, 3a - affected gooseberry leaves, bordering gooseberry veins
The diseases described above can affect both the gooseberry and currants, and even other plants.
At the same time, our gooseberry has its own disease. This is a gooseberry mosaic that is a viral disease.
The virus can live and develop only in the cells of living organisms. It is distributed as sucking insects, such as aphids, and herbivorous mites, with the juice of diseased plants, as well as through non-disinfected garden tools after pruning infected bushes.
Symptoms. When gooseberry bushes are affected by this disease, a bright yellow pattern begins to appear on the leaves, which is located along the main veins.
Shrubs cease to grow, produce very poor fruit, leaves are small and wrinkled.
Control measures. The gooseberry mosaic is practically not treatable. Diseased bushes must be excavated and immediately burned.
In order for the gooseberry to avoid this disease, we will take preventive measures: acquiring and planting healthy seedlings, process bushes against sucking insects in a timely manner so as not to carry the disease, observe quarantine measures.
At the end of the article are some general tips on processing plants:
- We begin processing the gooseberry with all these solutions as soon as the first signs of the disease appear with an interval of 10-12 days.
- If it rains within 5 hours after our treatment, spraying must be repeated.
- Two weeks before the scheduled harvesting of berries, we finish processing the bushes with all the preparations.
- It is best to treat gooseberry bushes against diseases and pests in the evening or in case of overcast daytime.
- When processing, try to moisten abundantly not only the upper side of the leaves, but do not forget about the bottom.
In this article, we met with various gooseberry diseases and learned how to deal with them. Now we need to deal with the pests of our beloved gooseberry, but this is already in the next article.
Gooseberry: diseases and their treatment, spraying
In the garden, gooseberry-related diseases spread rather slowly, but always steadily lead to lower crop yields. To know all the characteristics of gooseberry disease and their treatment should be possible before planting. Having gained all the necessary knowledge about gooseberry diseases, as well as about the fight against it, you can immediately increase the crop yield index several times already this season.
Pretty easy to prevent spread of the disease and stop its influence on culture. It is imperative that plant protection measures be observed and the dosage correctly calculated using special agents to kill parasites and pathogens. Do not neglect all available methods of combating parasites.
Gooseberry diseases and control
Causative agent - mushroom Verticillium danhia Kleb. He is able to quickly hit the rhizomes of the plant, so the mycelium spreads through the vascular system of the plant, resulting in its complete blockage of the biological mass. During the verticillary wilting of the plant, the access of nutrients to the growing shoots of the plant begins to stop, the leaves on the crop begin to fade and eventually fade, the bushes dry out. The affected root system quickly rot.
On the roots, on sections of branches, veins in the leaves with a large amount of moisture, the development of the white mycelium occurs, as well as the active formation of plant spores. The disease most often affects those crops that grow on heavy clay soils, as well as in the area of low areas with a special stagnation of water. The source of the lesion begins to persist for a long time in infected cultures, as well as in diseased plant debris.
How to spray gooseberries?
It is worth notingthat the response to the disease in the culture should take place immediately. Compliance with all the rules of cultivation of culture, the use of healthy material for further planting, regular elimination of all dried branches and bushes, together with a clod of earth, as well as further burning of the culture. During the industrial cultivation of a plant, it is worth spraying and watering at the very root with a 0.2% solution of foundationol.
- Mealy dew characteristic of gooseberry disease.
Sphaeratheca morsuave is considered the causative agent of this disease. A mildew dew can quickly infect young leaves and shoots of a plant, as well as their fruits. With the onset of the summer season, individual spots appear on the plant, which are presented in the form of arachnoid. Such a raid in a short time affects all neighboring leaves, as well as the very tops of the shoots. Over time, the mycelium begins to thicken noticeably, begins to change its color to gray, felt, and black fruit bodies that have a hibernating stage actively form in it.
The leaves on the plant remain underdeveloped, quickly change their color to brown and dry up, young shoots are severely deformed under the influence of the disease. The berries of the plant develop poorly and slow down their mouth, begin to become covered with white bloom, shrink and become completely dangerous for use. Infection into the plant continues to persist in the bark of the affected shoots of the plant, as well as in the affected remains. If the infection becomes widespread, the susceptible varieties of gooseberry will quickly dry out, their leaves are deformed, and the growth of shoots stops, and the hardiness of shrubs suffers greatly. In the end the plant completely loses its crop of berries.
- How to deal with powdery mildew?
To fight with such a disease, it is necessary to comply with all the rules of growing a crop, and it is also best to plant zoned gooseberry varieties that are resistant to powdery mildew. Phosphate and potash fertilizers should be applied in accordance with the needs of crops. It is imperative to cut, and then burn the affected areas of the plant. In the presence of the first signs of infection of a plant, it is imperative to spray the crop with the help of means tiovit Jet, as well as soon.
If the symptoms of the disease appear constantly on the fruits, then it is necessary to spray the culture four times a day. The first is carried out before the flowering process of the plant, the second after the flowering process, the third after the fruit is gathered from the plant, and 4 - 10–14 days after the previous spraying of the crop.
Gray rot on gooseberry, manifestation in springtime
The causative agent of the disease is mushroom Botrytis cinerea Pers. Able to infect the fruits and leaves of the plant. Болезнь серая гниль способна сильно проявляться в сезоны с большим количеством осадков, а также во время загущённых посадок культуры.In most cases, the spores of the fungus move and spread to other cultures through water flow, wind and insects from other plants that are affected by rot. On the leaves of the plant, brown sprawling spots begin to develop without any special bordering.
In the hot season necrotic fabric on the spots begins to actively crack and fall out, if there is too much precipitation on the street, then a smoky gray scurf with sporulation begins to form on it. The affected fruits begin to actively rot, but with all this, their colors almost do not change, the berries simply dry up over time.
If there is too much rain on the street, then the mycelium of the virus begins to actively grow through the peel on the plant, and spores of the fungus appear on it. Infected fruits, which are completely covered with a smoky gray coating, fall to the ground. The disease is very common on the gooseberry, as well as on the currant, but on the currant to meet such a disease can be much less. Gray and dense plaque can often be found on juicy fruits. The infection continues to persist in the affected plant residues of the plant.
Measures to combat this disease in the springtime are that it is imperative to carry out the complete removal of the damaged parts of the plant by pruning. Timely collection of infected berries, as well as residues from the plant, thinning of the culture for a better indicator of illumination, as well as for high-quality ventilation of the culture. Spraying plants for prevention should be carried out in conjunction with a special tool against the development of powdery mildew. Also, such a spraying can get rid of the spread of gray rot on the plant.
Gooseberry bush - description
Gooseberry is a low shrub - up to one hundred twenty centimeters tall, with a peeling brown or gray bark. On cylindrical shoots are thin needle spikes. Gooseberry leaves are petioled, cordate-ovate or rounded, three-five-lobed, dull, pubescent with short fibers, obtuse-toothed edges of the leaf plate. Greenish or reddish flowers, single or several pieces, grow from the leaf axils. Gooseberry - the earliest of the berry shrubs honey plant. Gooseberry berries, oval or spherical with a clear venation from 10 to 40 mm long, bare or covered with coarse bristles, ripen from June to August. If the original fruit has green color, then thanks to the work of breeders today in the garden grow red gooseberries (varieties Krasnoslavyansky, Ravolt), yellow gooseberries (varieties Yellow Russian, Spring), white gooseberries (Triumph, Belarusian Sugar) and even black gooseberries (varieties Negus, Protector). Although there are still popular varieties of the color familiar to this berry - green gooseberry varieties Malachite, Jubilee, Ural Emerald, and many others.
This article is devoted to pests and diseases of the gooseberry and fight against them, but if you follow the rules of planting and caring for the gooseberry, then all these troubles can be avoided.
Gooseberry diseases and their treatment
Unfortunately, the gooseberry has many enemies among insects, and the gooseberry is sick with various diseases. However, if you follow all the rules of growing and caring for this crop, gooseberry diseases and pests will not get a chance to settle in your garden. But even if trouble happens and the gooseberry becomes sick with something, nothing irreparable will happen if you recognize the trouble at the very beginning and take the necessary measures to save your garden, but in order to find out the problem, you need to have information about it, and we are ready for you provide it. In this chapter, we will answer most of your questions about what are the diseases of the gooseberry and how to save the gooseberry from certain diseases.
Mealy dew on gooseberry.
Most often, this fungal disease develops on the gooseberry or currant. Mealy dew looks like white bloom on gooseberry berries in the form of cobwebs. European powdery mildew and its American variety (sphere library), which we will discuss later. White berries on the gooseberry - is the beginning of the disease, which is important not to miss. Gradually, the white loose patina becomes a dense brown crust, diseased shoots bend and die, the leaves turn yellow, curl, break, the berries crack and shovel is still green. The whole crop of gooseberry can perish, and within a few years, if we neglect the treatment, all plants can be lost. The fight against powdery mildew on the gooseberry should begin immediately after the first symptoms of its appearance are detected: if the gooseberry is covered with bloom during flowering or fruiting, spray it two or three times with a weekly or ten-day interval with a solution of soda ash and 5 g of soda 50 g of rubbed soap on 10 liters of water. Affected berries and shoots destroy. If you have found powdery mildew even before disclosure of the kidneys, act for sure: the best remedy against powdery mildew is spraying with fungicides. Treat the gooseberry bushes and the soil beneath them with a solution of nitrophene or a 3% solution of ferrous sulfate, or a one-percent solution of copper sulfate. Not bad proved in the fight against this main enemy of gooseberry preparations such as foundationol, chorus and topaz. As a preventive measure, it is recommended to dig the soil in the area in spring and autumn. You can avoid fighting the disease by growing gooseberry varieties resistant to powdery mildew - Eaglet, Consul, English Yellow, Northern Captain, Chernomor and others.
The field of gooseberry.
Sphereoteka is the American powdery mildew, which is even more common in our gardens than the European one. This kind of powdery mildew is not much different from the European one in symptomatology, and the means of dealing with it are about the same. So, What to do if the gooseberry is covered with a touch of a sphere library? It is necessary to start the treatment with fungicides as soon as possible and not stop at a half result, otherwise everything will have to start over. Treat the gooseberry from the sphere library and be sure to determine the cause of the disease, that is, find out what agrotechnical errors caused the gooseberry susceptibility to American powdery mildew, and eliminate them. Do not neglect the preventive measures that strengthen the immunity of the gooseberry to disease.
Spots on gooseberry.
The causes of stains may be several. If at the end of May or at the beginning of June gray-brown or red spots with a yellow rim began to cover the leaves and berries of the gooseberry, and then the spots turned white, and only the rim around them remained brown, you are faced with white spotting, or gooseberry septoriosis. By August, the leaves may fall off en masse, the growth of shoots will noticeably decrease, and the harvest of the next year will be threatened. It must be said that septoria affects primarily weakened specimens, so be attentive to the health of your plants. It is possible to fight white spot by treating gooseberry and soil around a bush with fungicides. Be sure to remove from the bushes all the affected leaves and cut the shoots to a healthy tissue.
There may be orange-colored pads on the leaves, flowers, and ovaries of the gooseberry — it is a rust glass that often affects the plant if sedge grows nearby. Small yellowish spots on the upper side of the leaf plate and yellow-orange growths on the lower side of the leaf are symptoms of columnar rust, but it can strike the gooseberries only if cedar or pine grows somewhere near. Against both rust, an effective remedy is the triple treatment of the gooseberry with a one-percent solution of Bordeaux liquid or any other fungicide. The first session should be carried out when the leaves bloom, the second - with the appearance of buds, the third - after flowering. If the rust damage was very strong, spend the fourth spraying ten days after the third.
Gooseberry fruit is affected by the disease of the plant with powdery mildew - it is covered with white bloom, which then becomes a brown crust, cracks and falls from the bush, before it has matured.
Scab on gooseberry.
Actually, I had never heard that gooseberries were sick with scab. Usually this problem occurs in fruit trees and potatoes. Other berries, such as strawberries, strawberries, raspberries, blackberries, currants and blueberries, are not sick with scabs. True, sometimes "scab" amateur gardeners call powdery mildew on the gooseberry. But if you suspect that your gooseberry could get scab from an apple tree or from some other plant, treat the gooseberry with Bordeaux liquid, phytosporin or copper vitriol.
Gooseberry turns yellow.
Why does the gooseberry turn yellow? Yellowing of the leaves is the first sign of a lesion with a spirotine powdery mildew. Yellow stains on the leaves also occur when a gooseberry is infected with a mosaic, a viral disease that, unfortunately, cannot be treated. Mosaic shrubs should be uprooted and burned. To prevent this disease from appearing in your garden, carefully inspect the gooseberry seedlings before buying and in no case acquire suspicious or weak specimens.
Aphids on gooseberry.
Gooseberry shoot aphid infects the leaves and young shoots of gooseberry, feeding on their juice. As a result of the life activity of aphids, which gives several generations over the summer, the leaves curl, and the shoots slow down and, finally, stop growing. It is not easy to detect aphids right away - it is very small in green and can be noticed when it is already too much. Cut off and destroy the damaged tops of the shoots and process the gooseberry bushes with an atellik or karbofos. If you had time to detect the appearance of aphids at the very beginning, it is enough to spray the gooseberry with a solution of three hundred grams of soap in ten liters of water. And carefully study the site: if you find an anthill on it, know that the aphid will appear on the gooseberry all the time, and you need to fight first with not an aphids, but with ants.
Caterpillars on gooseberry
In early spring, caterpillars that emerge from eggs laid along the veins of the underside of the leaf with butterflies of yellow or pale-footed gooseberry saws attack the gooseberry leaves that just open. One butterfly can lay up to 150 eggs, and two or three generations of sawflies develop in one season. Gooseberry treatment with insecticides (aktellik, karbofos etc.) against the first generation of caterpillars is carried out from the moment of bud opening until the buds form, the next time you need to spray the gooseberry immediately after flowering, and if after picking the berries again you find caterpillars on the gooseberry, spend the third treatment of the bushes insecticides. Try every year to change drugs that destroy insects.
Caterpillars of the gooseberry moth, which are four centimeters in length, behave in a similar way. They are destroyed by the same means and on the same dates as the caterpillars of the yellow or fine-legged sawfly.
Light-green caterpillars with a black head, emerging from the gooseberry eggs laid in the gooseberry flowers, eat the ovary of the fruit, enveloping it with cobwebs. One caterpillar can destroy 6 berries. Remove from the bush and destroy the spider nests discovered by you, and after the gooseberries fade, spray the gooseberries with insecticides (actellic, karbofos, etafos). Next year, do a preventive spraying of the gooseberries with these preparations before flowering.
Currant glass on the gooseberry.
This butterfly lays up to 60 eggs in the cracks of the bark of the gooseberry, and the caterpillars that appear feed on the core of the shoots, gnawing them from top to bottom, making a tunnel from the top to the bottom of the shoot. From this damaged branches wither and dry. In the fight against currant glass, the same preparations are used as in the fight against fire moth, sawfly and peppered moth. In addition, it is necessary, after finding damaged caterpillars, to remove them immediately, leaving no stumps, and process cuts with garden pitch.
Currant gall midges on a gooseberry.
They are harmful to gooseberries and currant gall midges - sprouting, floral and leafy, striking plants in too thick plantings. They lay larvae in shoots, flowers and gooseberry leaves that feed on these parts of the plant and destroy them. After harvesting, it is necessary to destroy gall midges with the same insecticides as the insects we have already told you about. As a preventive measure in the spring of next year, treat the gooseberry with insecticides again.
Currant bud mite on gooseberry.
This insect damages the gooseberry buds, penetrating into them and feeding on the sap of young leaves. Because of this, the kidneys look too large and ugly compared to healthy ones. In addition, this tick carries virus terry, dangerous to currants. With ticks infected with bushes in autumn or early spring, all unnaturally large buds should be removed and the plant treated twice with colloidal sulfur solution at the rate of 100 g per 10 l of water or an ISO preparation in accordance with the instructions. The first treatment is carried out during the opening of the buds, and the second - immediately after the gooseberry blooms.
Processing gooseberry in spring.
Today there is a huge choice of means of combating insect pests and all kinds of plant diseases, and the old, usually labor-intensive methods of plant prevention are undeservedly forgotten. And in vain. Let us remind you of one remedy that awakens the gooseberry in the spring after the winter holidays and strengthens its immunity to diseases and pests. In early spring, in late March or early April, a bucket of water brought to a temperature of 80 ºC, pour it into a watering can with a spreader and quickly pour gooseberry bushes with this boiling water. One bucket of water should be enough for five, at least for three bushes. Then collect last year's foliage from the site and burn it along with all the harmful fungi and viruses, as well as their vectors. Cover the ground under bushes with pieces of roofing material or roofing felt to prevent the butterflies laying eggs on the ground parts of the gooseberry from flying out of the ground, and after flowering, when this danger is over, the covering material can be removed.
Treatment of gooseberry disease.
In early spring, gooseberries are removed from broken and weak branches, cutting off the darkened ends of the shoots, frostbite or affected by powdery mildew, remove too large compared to other buds, because they can be affected by currant bud mites. At the beginning of bud break, prophylactic treatment of gooseberry bushes and soil at a site with nitrophene or a 3% Bordeaux liquid is carried out. After flowering, for the purpose of prophylaxis, the gooseberry is sprayed with a one-percent Bordeaux liquid twice a week apart. In the summer, it is necessary to treat the gooseberry from powdery mildew with a solution of soda ash and soap twice with a break of 10 days. After harvesting, anthracnosis is prevented or treated with a one-percent solution of bordeaux liquid or another fungicide.
Processing gooseberry pests.
At the beginning of the formation of buds on the gooseberry, it is sprayed from gall midges, aphids and sawflies with karbofos (75 g per 10 l of water) or rovicourt (10 g per 10 l of water). Against a kidney tick, spraying with a solution of colloidal sulfur at the rate of 30-40 g of the drug per 10 liters of water is used. After flowering, the gooseberry is sprayed from insects by pests of karbofos or aktellik.
Gooseberry processing in the fall.
In the autumn, it is necessary to prune the gooseberries, remove the foliage and other plant residues from the site, treat the gooseberries and the soil around it with nitrophene, sprinkle the rows between rows, pour plenty of water and feed the gooseberries and grind the plot for the winter. When the snow falls, spray them with gooseberry bushes and you can forget about it until the end of March.
Than to feed gooseberries.
It is well known that all plants need nutrition, which they supply with organic and mineral fertilizers. How to feed the gooseberries in the spring, to strengthen its resistance to diseases and pests and to provide abundant fruiting? At this time of the year, the gooseberry needs nitrogen fertilizers most of all - before blooming, add 25 g of ammonium nitrate or 30 g of urea per square meter of land. Potash phosphate fertilizers need to start making only a year after planting the gooseberry, and even after a few years - it all depends on the composition of the soil on the site. They are brought in the fall: one square meter for half a bucket of rotted manure, 15 g of potassium chloride or 100 g of ash and 45 g of superphosphate each. Fertilizers are scattered around the bush at a distance of up to two meters from the center around the circumference — the roots of the bush expand to such a distance, and then they are buried to a depth of about 10 cm.
This is a common name, or rather, a sign of the most common gooseberry disease and many other garden crops - powdery mildew or a sphere library. Она разделяется на два вида (европейская и американская), оба из них имеют практически одинаковые внешние проявления, но отличаются лишь видом грибка, являющегося причиной заболевания.
Первые симптомы мучнистой росы появляются уже весной или в начале лета, сразу после цветения куста. На молодых вегетативных частях растения (обычно с нижней стороны) появляется характерный белый налет, имеющий рыхлую структуру.
In the initial stages of the disease, it is well erased, so some gardeners take contamination for ordinary pollution. Gradually, the colonies of the fungus spread to the gooseberry ovary, the fruit and cover most of the plant. The raid is getting denser every day, eventually it takes on a dark brown shade.
Against the background of the disease, growth and development of the shoots ceases, and their curvature occurs.
The leaves dry, curl and begin to separate from the plant. Powdery mildew causes the greatest damage to the crop - the fruits stop growing, a strong deposit appears on the berries, they burst and crack.
If you do not start treatment in time, the infected gooseberry bushes die within two to three seasons, and the pores of the fungus with the wind and insects are transferred to nearby fruit bushes.
Mealy dew is able to remain on fallen leaves and branches even in the most severe frosts, and when the optimum temperature is reached, the disease is activated again.
When mushrooms are detected on a plant, the fight against them should continue throughout the season, but we must not forget about preventive measures.
There are many different methods of treatment for the effectiveness, the most common ones:
- All infected parts of the plant, including berries, must be removed outside the site and completely destroyed.
- In early spring it is necessary to treat the bush with hot boiling water, since the high temperature kills the fungus.
- Until the formation of the first ovaries, fungicides are recommended. Bordeaux liquid (a mixture of copper sulphate and milk of lime) or soda ash solution (50 g per 10 liters of water) is most commonly used. To enhance the reaction and interaction with the bush, it is recommended to add 50 g of soap to the solution. Spraying chemicals preferably carried out in the morning.
- In the later stages of the disease, an infusion of wood ash is used (300 g of dry mixture per 10 liters of water). This tool can handle both ground and upper parts of the bush.
- When infecting the whole planting of gooseberries and nearby plants, it is necessary to apply strong complex fungicides. For example, Topaz, Fundazol, Fitosporin and others.
- As an additional measure, organic fertilizers can be applied, such as bird manure, mullein or humus (in a ratio of 1: 3 relative to water). After feeding, the vital activity of bacteria increases, which subsequently begin to feed on the mycelium of the sphere library.
There are a number of gooseberry varieties with increased resistance to fungal diseases, including powdery mildew. If a site has already been observed, it is recommended to plant them.
The second most common gooseberry disease, which is also a fungal infection. The onset of the disease usually occurs in mid-summer, especially in the rainy season.
First, the leaves of the plant are affected - small white specks with a glossy structure appear on them. Over time, they merge with each other, spread over the entire surface of the shrub, acquiring a brown tint.
If the necessary control measures are not taken in time, the leaves begin to dry and fall, the appearance of new shoots is reduced, the quality of the crop deteriorates.
Anthracnose responds well to treatment if you pick the right drugs. It is very important to remove fallen leaves, cut off the already infected vegetative parts of the plant with subsequent destruction.
As a fungicide, Bordeaux liquid is recommended at the rate of 100 g per 10 liters of water. Processing should be carried out at least 4 times per season with an interval of 15-20 days.
Septoriosis (white spot)
It is a type of anthracnose, but the main difference is in the form of a fungus that causes infection of the bush. With this disease, characteristic small spots appear on the leaves, which have a grayish tint with a brown rim.
As the plaque gets infected, black dots are formed, in which an increased number of fungal spores is noted. The disease leads to curling of the leaves and their shedding. In advanced cases, septoriosis completely affects the entire shrub, which leads to its complete drying.
As a treatment, the same fungicides are suitable as with anthracnose. Plus, as a preventive measure, it is recommended to treat the soil near the gooseberry with a weak solution of potassium permanganate, boron or zinc. It is desirable to carry out the treatment twice per season - in spring and autumn.
There are several varieties of this disease, but the gooseberry most often affects the toe rust. This is a fungal disease affecting the leaves of the plant.
It received its name because of the specific shape of the spots, which look like small glasses. In the early stages, they take a bright orange shade and are located mainly on the lower part of the leaves.
The peak of infection occurs at the beginning of spring, when the pores of the fungus are transported by the wind and insects from the ground or other plants. As the infection becomes, the foliage twists and twists, and then falls. If you do not start treatment, rust affects the berries of the gooseberry. Affected fruits lag behind, deform and dry.
The most effective way to combat gooseberry rust is to observe preventive measures and planting rules. It is recommended to plant only those varieties that are resistant to disease. Plus, the disease is often observed when landing close to water bodies, as well as in lowlands and areas with high humidity.
These points should be taken into account even before the gooseberry is planted.
If the disease could not be avoided, rust responds well to treatment with a 1% solution of Bordeaux liquids (100 g per 10 liters of water). Processing is carried out in three stages - at the time of formation of the ovaries, after the start of flowering and 10-14 days after its completion.
Some time after infection, a characteristic pattern of bright yellow or light green color appears on the leaves. Spots are always located along the veins of the sheet, so the disease is easy to distinguish, even in the early stages.
As the disease progresses, the bush ceases to grow, new shoots and ovaries do not appear. New sheets have a smaller size and small wrinkles on the surface. Fruiting practically does not occur.
The gooseberry mosaic is practically not treatable, therefore, when an infection is detected, it is necessary to dig out a sick bush and destroy it. An important role is played by the further prevention of the disease - the treatment of planting with insecticides to reduce the number of insects, the purchase and planting of new bushes to update the genetic material of this garden culture.
Many of the typical gooseberry disease and affect the fruits of this plant, from which significantly deteriorates the quality and quantity of the crop. When identifying any symptoms, it is important to accurately determine the disease, since the methods of treatment differ in each case.
The most common signs of gooseberry disease are:
- Appearance of yellowness. If yellowing of leaves and berries begins, it is usually a powdery mildew or spherotek. This disease affects the fruits only in the later stages, so before the appearance of yellowness, you can notice a characteristic white patina. If there are small yellow spots on the leaves along the veins, the bush is probably infected with a mosaic, which has not yet been effectively treated.
- Mold on the berries. This symptom is characteristic only for powdery mildew, however mold can appear due to infection of the bush with aphids. To determine the disease, it is necessary to carefully examine the entire hive for the presence of clarifying signs.
- Fall of berries and leaves. Virtually all diseases cause shrub shrinkage, followed by abscission of foliage and fruits. However, the cause may be the lack of macronutrients in the soil, for example, such a symptom is observed with a nitrogen deficiency.
- Scab, which is one of the most common plant diseases in the home plot, is extremely rare in gooseberries. Despite the fact that the risk of infection is minimal, when dark brown spots characteristic of scab on leaves and fruits appear, the planting should be treated with a 1% solution of Bordeaux liquid (75-100 g per 10 liters of water) or copper sulphate (40 g per 10 liters ).
Mealy dew and sphere library
Symptoms of powdery mildew are manifested by the development of a whitish plaque on the foliage, shoots.
With the progression of pathology, the white bloom thickens and darkens.
Affected fruits do not develop, dry and fall off. The leaves twist and dry, shoots from above become crooked, dark and fall off.
powdery mildew on gooseberry
The bush can be destroyed in a couple of years.
The sphere library is a common disease and carries danger.
The measures for getting rid of the disease are as follows:
- Use processing fungicides.
- Before the buds bloom, spraying the plant and the soil beneath it with nitrafen is performed.
- Can be treated with a 3% solution of ferrous sulfate (30 g. Per bucket of water).
Immediately after flowering of the shrub or when the first symptoms of the disease develop, they are treated three times with an interval of one and a half weeks, using a solution of soda ash (50 g. Of soda, 50 g. Of soap, a bucket of water).
You can apply bacterial techniques.
To do this, pour manure pour 3 parts of water and give infusion for the 3rd day. The composition is diluted 1 to 2 with water, filtered and treated for them diseased gooseberries.
The technique is based on the ability of the bacteria that are present in the manure to kill the disease. Spraying can be done after harvesting.
Well from this disease helps "Fitosporin."
You should also cut and burn diseased shoots, fruits.
In spring and when autumn, the ground under the gooseberries must be dug up, in the spring - to bring mulch.
Septoria or White spot on gooseberry
On the foliage you can see small angular or round specks (size 3 mm).
Initially, the spots are brownish, then they become white in the central part and only the rim of the leaf remains brownish.
Small specks can be observed on the fruits
In the spots ripen fungal spores, the disease develops in the summer. If the gooseberry is severely affected by the disease, the foliage may fall off.
Septoriosis also destroys leaf stalks, green shoots, stalks, where brown ulcers can be seen.
Measures to combat garden spotting are as follows:
- The infected area, plants and soil are well treated with nitrafen or copper sulphate.
- Spraying performed in the spring, when the buds have not yet dismissed.
- If necessary, for treatment, you can use Bordeaux liquid (0.1 kg per bucket of water) or the same solutions that are used to combat anthracnose.
The treatment is carried out with the development of the first symptomatology of the disease.
The second time is treated after a week and a half after harvesting the berries.
You should also remove all flown foliage under the bushes of plants (there are fungal spores there) and dig the ground in the near-stem circle (when cold weather comes or in springtime).
Rust on gooseberry
Symptoms are manifested by the development on foliage, flowers, fruit ovaries of large enough yellowish pads (there is a development of fungi).
There are two types of pathology - goblet and columnar.
The development of the disease is associated with sedge, so you need to free the site, sedge meadows should be cut at least 25 meters.
It should be grown varieties of fruit bush, resistant to the disease.
The treatment is quite simple.
It is necessary to spray 1% Bordeaux liquid or other fungicides:
- The first time processing is carried out in the period of foliage blooming.
- The second time is treated during budding (the most important treatment!).
- For the third time, the flowers will bloom immediately.
With a strong infection of the garden culture with rust, use processing 4 times - a week and a half after the third spraying.
You can use the universal drug "Fitosporin".
You should also collect and burn all overgrown foliage, loosen the ground around the bushes.
What are the diseases of gooseberry, and what are the measures to combat them
Fungal infections are one of the worst enemies of plants, including the gooseberry. Gooseberry diseases of the fungal nature are mealy dew, anthracnose, as well as rust, mycoplasmosis, and septoria.
1. Mealy dew
Mealy dew or sphere library is a rather frequent guest of gooseberry or currant bushes. The initiator of this gooseberry disease is a mushroom. In the spring, spores are dispersed and new bushes become infected. All parts of the plant are affected by this type of fungus. Initially, a whitish bloom appears, which then turns brown and becomes denser. When the disease is a deformation of the branches, leaves and fruits. As a result, the plant dries out and dies in 2-3 years.
How to treat powdery mildew? In order for the plant not to be threatened by this fungus, it is necessary at the very beginning to choose disease-resistant gooseberry varieties.
• If the plant is already sick, you can add solutions of elements of copper boron, manganese sulphate and zinc to the root area.
• For prevention in the spring, during the period of budding and flowering, the bushes are sprayed with blue vitriol at the rate of 300 grams per 10 liters of water. Repeat spraying after 8-15 days, and the last spraying should not be carried out later than 15 days before picking.
• Soda Ash and Laundry Soap. 50 g of soda and soap are diluted in 10 liters of water. This treatment is done in 10 days.
• Wood ash or charcoal treatment. At the rate of 3 kg per 10 liters of boiling water. The solution is sprayed with bushes once every 10 days.
• Bleaching powder. Take 2 tablespoons of funds for 10 liters of water
• Mustard powder. 2 tablespoons of mustard powder added to 10 liters of water. The solution is heated to boiling. Boil the composition for at least half an hour, then filter. Treat the whole plant and especially young shoots
• Inkstone. 300 g per 10 liters of water. Before treatment, the infected parts of the plant are removed. The soil on which the infected shoots were located should also be treated with this solution.
• The method of struggle with the help of bacteria. To do this, add a triple portion of water to one part of rotted hay or mullein, insist on this solution for three days. Treat gooseberry with a diluted 1: 3 composition. Bacteria of this solution, falling on the bushes, eat the fungus.
All solutions are used three times: before flowering, during and after leaf fall.
2. Anthracnose countermeasures
Anthracnose can also affect gooseberries. It is expressed in the fact that brown spots appear on the plant, the leaves are deformed and curled. Fruits may fall off or taste sour.
The following measures are taken to get rid of this disease:
• Remove diseased branches and leaves in autumn and spring.
• Digging the soil near the plant.
• Treated with “Home”, a solution of 40 g in 10 liters of water.
• Sulfur colloid. Sprayed at the time of flowering.
• Bordeaux mixture. 40 g of vitriol in 10 liters of water. Conduct treatment 2-4 times depending on the severity of the disease. Begin processing before flowering at intervals of 14 days. For more serious cases, make 1 percent solution.
3. Glass rust.
The reverse side of the leaves is covered with yellow growths, which are then transferred to the stems and berries. After that, they become like a felt patina. The disease usually occurs where there is a sedge weed.
To get rid of rust:
• make soil digging,
• removal of thickets of sedge weeds,
• apply top dressing with potassium and phosphorus fertilizers,
• spraying Bordeaux mixture, phytosporin and fungicides.
4. Mycoplasmosis or Terry
In mycoplasmosis, the mite infects the plant buds. It reborn and the characteristic smell disappears, leaves from five-lobed become three-lobed, the brush becomes thin, the flowers are purple.
For prevention and treatment:
• remove aphids and ticks with various preparations;
• fertilize plants with complexes containing boron, manganese, molybdenum,
• Nitrogen fertilizers are not used.
Septoria is characterized by the appearance at the initial stage of brown specks, which then turn white from the center, the border remains dark. When the disease is neglected, the berries are affected and the leaves fall.
To get rid of the fungus, the plants are sprayed:
• remove affected branches,
• fallen leaves are burned in autumn,
Physiological gooseberry diseases
Also quite often occur with improper care, inappropriate soils.
Such disorders usually occur in the bushes with a lack of nutrients.
• So, with a lack of nitrogen, the plant may slow down growth, the leaves turn yellow, the fruits fall off. Such bushes need to be fed with nitrogen fertilizers, in accordance with the dosages on the packages or spray vegetative plants.
• With insufficient phosphorus content in the soil, dark green and yellow-green spots appear on old leaves, shoots are thinned and the buds are not sufficiently developed and the plant's resistance to cold weather decreases.
• Potassium deficiency causes poor absorption of nitrogen and phosphorus. The leaves turn pale, then purple-brown stripes appear on them, the leaves die off. Почки формируются неполноценными, и в последующем дают недоразвитие плодов и новых побегов, снижается зимостойкость крыжовника.
• Дефицит магния также вызывает заболевания и крыжовника. Этот недостаток снижает жизнеспособность растения, ослабляет корневую систему.
• Lack of calcium and its excess inhibits the root system, while the roots become similar to the stumps. The fight against this is to reduce watering, drainage of peatlands
• If the plant does not have enough iron - then the leaves and the ends of the shoots turn yellow. It can occur if the soil is over-humidified, insufficiently organic, as well as during drought. In order to prevent enrich the soil with humus, making iron sulfate (150 g per 10 liters of water).
The disadvantages of these elements are corrected by the introduction of appropriate fertilizers, proper care, watering, removal of weeds, digging the soil.
For a more accurate determination of the composition of the soil, you can do an analysis, then you can know exactly which element is missing.
Prevention of gooseberry disease
• not allowing thickening of bushes, cutting out dried and damaged branches,
• collecting and removing fallen leaves by burning,
• You can plant plants near the gooseberries that have pest repellent properties: marigolds, garlic, dill, chrysanthemums.
• in the early spring pour boiling water over the bushes to destroy the spores of fungi,
• spray the bushes with a solution of zircon in early spring, to increase their immunity.
Rust features and ways of dealing
- The causative agent of columnar rust is one of the types of fungi. This fungus has several hosts. This fungus spends the winter on Siberian cedar or on Maymouth pine, which causes the active development of tumors on the trunks and branches of the plant. They begin to develop spores, which in the spring time affect and berry crops. By the middle of the summer season, yellow and brown spots begin to appear on the upper side of the leaves, and on their lower side a large number of bright orange forming pads with sporification can be seen.
- During the strong stage of the fungal infection of the plant, the leaves of the gooseberry begin to grow and dry in a short time, and then fall to the ground prematurely. The development cycle of this plant is quite complicated: in the summer, on currants or cedar, which grow nearby. The infection continues to persist inside affected coniferous crops, as well as on plant debris.
- The causative agent of goblet rust is considered to be the mushroom Puccinia ribesiicaricis Kleb. The fungus prefers to spend the winter on sedges, in springtime the spores of the fungus begin to actively affect berry crops. At the end of May - beginning of June, on leaflets and cuttings of plants from the outside one can find bulging bright yellow spots of the disease. On the lower side of the leaf plate, the goblet-shaped écia develop, which carry particular disputes.
- The affected leaves and berries begin to crumble quickly to the ground in the middle of the summer season, so the symptoms of the disease quickly disappear. Diseases of rust fruits contribute to their cultivation on the territory of lowlands, where sedges actively grow, where infection continues for a long time. The glass type of rust in most cases attack the currants, and not the gooseberries.
How to fight? Compliance with the general rules for growing plants, spatial isolation from other types of conifers and the rapid cutting of sedge in the garden plot will all help the plant not to get sick. It is also worth regularly collecting plant residues. Prophylactic spraying of shrubs should occur using 1% Brodsky mixture or its special substitutes (XOM, Agiba-Peak) during leafing, and with the strong development of columnar rust, it is worth re-spraying after collecting the fruits with the same tool.
Alternaria - gooseberry disease
The fungus of this disease, which in a short time affects the leaves, shoots and fruits of the culture. Black-gray spots appear on the sheets during Alternaria, which in most cases actively spread along the edges of the leaves and the leaf plate. By autumn, the affected plant tissue begins to become covered with a rich and velvety olive bloom, which consists of fungus spores. The affected leaves fall off earlier than the prescribed time and dry quickly.
On the young shoots and the fruit of the culture of the disease occurs depressed brown spots oblong in shape, and the leaves are covered with a strong bloom of olive color. The defeat of the shoots, as well as the premature fall of the leaves negatively affects the condition of the whole plant, weakens it and reduces resistance to low temperatures. The infection persists in the cortex of the affected shoots, as well as inside the infected plant residues.
Measures to combat the disease include the timely collection of plant residues. It is also worth carrying out each year preventive spraying of a shrub of a plant before the flowering process, and also, if necessary, after harvesting from a plant.
Anthracnose on gooseberry
First signs of development Diseases on the crop can occur by the end of the flowering currant, the peak of virus activity occurs in the second half of the summer season (July and August). Leaves, scapes, young shoots and berries of the crop, both currant and gooseberry, begin to be actively affected.
Initially, the plant develops separate light spots with glossy sporulation mounds. After the stain, they begin to grow rapidly, merge with the leaf and form large patches of affected tissue. During the entire summer season, several generations of a fungus with a large number of spores inside can develop on the leaves of a plant. On the petioles, as well as on the young shoots, anthracnose is formed in the form of small gray-blue ulcers, small gray grains may also develop on the fruit.
The growth of shoots on affected plants slows down significantly, there is a premature abscission of leaves, as well as a decrease in crop yield indicators. The infection continues to persist inside the bark of the affected shoots and within plant residues.
To fight this disease is exactly the same as with Alternaria.
Septoria on gooseberry
Such a disease able to hit both currants and gooseberries.
Already at the beginning of June, on sheets, small round spots with a red-brown border along the edges, which eventually brighten in the center, can be seen. In the necrotic tissue of the plant, bodies of a wintering nature, pycnidia, develop. Currant also affects shoots and fruits; small brown rashes appear on them.
The disease affects weak fruit plants..
The plant is affected by the root system. This is expressed in yellowing and wilting of the leaves, but at the same time they remain on the bush, without falling off
Measures to combat the withering of the gooseberry are as follows:
- Follow the rules of agricultural engineering.
- It is necessary to properly care for gooseberry bushes.
- When trimming shrubs should be disinfected cut zones Bordeaux liquid (0.1 kg per bucket of water) or carry out the lubrication of the garden pitch.
It is also necessary to carry out the prevention of verticillary wilt.
Mosaic on gooseberry
Symptomatology is expressed by the appearance on the foliage of a bright yellowish pattern along the main veins of a leaf of gooseberry bush in the form of stripes.
Mosaic on gooseberry
As the disease progresses, the leaf is crushed and wrinkled.
Garden plants that are affected by mosaic, do not give berries and practically do not develop.
Diseases that provoked the virus, almost no cure.
Plants with symptoms of pathology must be excavated and destroyed in the fire.
The methods of struggle are exclusively preventive in nature:
- Use of non-diseased planting material.
- Regular processing of horticultural crops against sucking pests to prevent the spread of gooseberry mosaics.
- Compliance with quarantine measures.
Prevention must be carried out.
Disease prevention in gooseberry
The basic rules of prevention:
- In the fall, follow all the diseased parts of the bush and burn them along with all the fallen leaves and berries.
- The ground at the base of the bush needs to be dug up.
- From the beginning of spring - until the bud breaks - you need to spray the gooseberry with a three-day extract of mullein and diluted with water in a 1: 3 ratio. Repeat spraying after two weeks.
- If shoots were struck, they should be sprinkled with lye made from ash. To do this, pour 1/3 of the ash into the bucket and top up with water. Boil the mixture for half an hour and finally add the shavings of laundry soap (40 grams). Sue and sprinkle.
- After the gooseberry blooms, it needs to be treated with soda ash (50 grams of soda and the same amount of soap are needed for 10 liters of water. You will need to spray the plant three times with a 10-day break)
Gooseberry Pests and Control
Consider the main gooseberry pests in more detail:
- Sawfly on gooseberry
False larvae of this type of pests eat up the leaves of bushes to the veins.
Adult larvae (size up to 10 mm) spend the winter in dense cocoons of cobwebs in the ground under a bush at a depth of up to 150 mm.
In the first days of springtime, the pupae with caterpillars, when blooming foliage, form into butterflies, which lay eggs from the bottom of the leaf plate along the veins.
One butterfly lays up to 140 eggs.
Sawfly on gooseberry
After a week and a half, the larva appear.
Green larvae with a brownish head.
During the summer period 2-3 generations of pests develop.
To fight with gooseberry sawflies need the same compositions that are used to destroy such insects:
All these solutions are able to destroy and sawfly.
Spraying to eliminate the first generation of caterpillars should be from the moment when the buds open until the formation of inflorescences, against the second - as soon as possible after fading.
If the larvae are found after picking up the fruit, processing can be performed again.
You can drop the larvae from the branches into an open umbrella. It is necessary to dig and tear through the ground under the bushes, remove and burn the leaf that has flown over.
Compositions for destruction will be described below.
- Gooseberry firing pin
This harmful insect is the most common and dangerous species for gooseberry crops.
Fruits affected by a pest ripen prematurely and dry out.
On them you can watch the cobweb.
Gooseberry firing pin
Butterfly nazhnevka in wingspan up to 30 mm, front wings dark with brownish transverse stripe and brownish specks, behind the wings are the lightest.
Caterpillars of pest size up to 20 mm, green with black head.
Winter pest pupae spend in cocoons from the web on the soil surface under the gooseberry bushes. In the springtime, butterflies are formed, they lay eggs in gooseberry flowers.
After a certain period, caterpillars form, which crawl into the ovary and eat them. One pest can damage up to 6 gooseberry fruits, wrapping berries with the finest gossamer.
In autumn, pests are sent to the ground for pupation and wintering.
To overcome the pest, it is necessary to systematically remove and burn the spiderweb nests from the gooseberry.
After the garden culture has faded, it is necessary to spray one of the following preparations:
These same tools are used to treat mosaics.
In case of an epidemic in the previous season, it is possible to spray the preparations before flowering.
The treatment takes place in conjunction with spraying against anthracnose and other pathologies.
- Shoot aphid on gooseberry
The insect infects the young foliage of a garden plant.
With a plentiful invasion of pests of bush foliage:
Fresh shoots infected with insects are deformed, poorly grown, their growth may stop altogether. As a therapeutic measure should be spraying in the spring until the disclosure of the kidneys.
Shoot aphid on gooseberry
Measures to protect the garden plot against anthracnose also eliminate the shoot aphid on gooseberry bushes.
To combat insect colonies in the summer, they are treated with the following preparations:
From unconventional methods of struggle, you can apply a solution of soap in a not hard water (0.3 kg per bucket).
The entomophages (for example, aphelins), which strike aphids by laying in them, are effective in destroying aphids from the shrub, so that huge hordes of aphids in the garden plot can be destroyed during the season.
Some experienced gardeners use white mustard powder to kill.
- Dangerous pest - moth gooseberry
Caterpillars gnaw up the leaves (or make holes in it) of a garden plant.
The butterfly of a dangerous insect in a wingspan of up to 50 mm.
It makes laying at the bottom of the foliage in the early to mid summer period.
The moth insect is destroyed by the same insecticides that are used against the following types of pests:
Spraying for the elimination of the first generation is carried out during the period of bud opening and before budding, for the destruction of the second generation - during the past ottsvetaniya.
If, after picking, new pest larvae are found, treatment can be performed again.
You can remove dangerous larvae from the branches in an open inverted umbrella.
- Spider mite
Mites live below the foliage, weaving it with the thinnest web.
In places of defeat, you can initially observe light points, then discolored areas.
With the strongest defeat of the foliage is like a "marble", with time dries and flies.
The plant culture, which was struck by a spider mite, greatly reduces the yield and frost resistance.
Fighting a pest is simple enough.
In springtime, when the buds are dissolved, while the females have not yet laid, the gooseberry is treated with any of the following solutions:
It must be remembered that sulfur-based products can burn the foliage when they fall on it.
Gooseberry disease can be avoided if the crop is properly grown, cared for and preventative.
Hopefully this information will help you grow good yields!
To start on prevention
In fact, gooseberry disease is easier to prevent than to fight them. This is a well-known fact, so before moving on to the list of ailments, I would like to talk about prevention.
- For gooseberry, there are special agrotechnical rules that must be clearly known and respected.
- Quite often, the cause of the development of diseases is the thickening of the plantings, so you should remove dry, weak and damaged shoots in time.
- Leaf litter is the ideal soil for the development of fungal diseases. Therefore, in the autumn care for gooseberries, it is mandatory to include the cleaning of fallen leaves and its subsequent burning.
- The soil under the plant is desirable to periodically loosen.
- It is worth making it a rule to treat plants with boiling water every spring - thanks to this event, active fungal spores will be destroyed.
- To strengthen the immunity, the culture should be properly and promptly fed and sprayed in the spring with a solution of “Zircon”.
For gooseberry are characterized by such diseases as:
- American powdery mildew,
As you can see, the list is quite extensive. Let's find out how each of the gooseberry diseases manifests, and how we can fight them.
The causative agent of this disease is a fungus and it affects the plants as follows:
- orange spots with yellow spore pads appear on the leaf plate,
- after a while these pads take a goblet shape,
- leaves become ugly and soon fall,
- fruits become one-sided, stop developing, dry out and do not stick on the branches.
To combat rust, use a 1% solution of Bordeaux liquid three times - during bud break, after flowering, and again after 10 days.
To avoid the occurrence of columnar rust, gooseberries are preferably planted in high areas where there will be no stagnation of water. For planting, it is desirable to choose varieties resistant to the disease.
If previous diseases could have affected other cultures along with the gooseberry, the mosaic is “its own” disease. This is a viral ailment and insects, both sucking and herbivorous, as well as infected garden tools can be its hawkers.
The mosaic is manifested by the following features:
- there is a yellow pattern on the leaves that stretches along the main large veins,
- plant growth ceases, new shoots are not formed,
- yields are rapidly falling,
- leaves become small and wrinkled.
As soon as signs of the mosaic were identified, the bushes should be immediately excavated and burned outside the site. This disease can be prevented by first paying attention to the health of seedlings, treating the crop against insects and observing quarantine measures.
