A beautiful, well-groomed garden that brings a rich harvest is the dream of any gardener. And he can bring joy not only in the spring because of the beautiful flowering and aroma, but also in the autumn during the harvest season of juicy and healthy apples.
But the yield of the garden may suffer as a result of infestation of trees by various parasites. Then the yield is in question, and the storm of defeat hangs over the whole garden. One of these pests is codling moth. This parasite can cause irreparable harm not only to the harvest, but also to the entire garden as a whole due to its rapid reproduction.
The biological features of the butterfly
The butterfly moth is brown or grayish in color. The wings have a transverse shape, a span of no more than 2 centimeters and a spot in darker colors than the body of a butterfly. To notice the infestation of a tree by a pest in the early stages is almost impossible, due to the fact that the butterfly leads nightlife and lays eggs on the fruits and leaves in the dark.
The number of eggs laid by females can reach hundreds, of which, after seven days, caterpillars of light red color with a brownish head appear. During one season, a butterfly can breed two generations of larvae, which can destroy almost the entire crop and significantly damage the fruit tree itself.
Life activity of a caterpillar
Hatching caterpillars enter the fruit by eating the flesh, reach the core, which prevents the fruit from developing properly. As a result, the fruits fall. Caterpillars of apple codling mills can get infected not only with apple trees, the pest can affect any fruit tree.
The apple moth can also affect already formed fruits, which, despite continued growth, can reach maturity before others and fall off under the influence of the pest’s vital activity.
The time of development of the caterpillar can reach the monthly period, during this time the insect can damage a large number of fruits. In the autumn months, the pest moves into the cracks of the bark of the tree, it takes the form of a pupa and lives until spring. For wintering, the caterpillars can choose harvest storage sites, sheds, cellars, or fruit crates.
The pest control can be carried out by various methods, the main task is to prevent insects from breeding and not getting into secluded places for wintering. In the initial stage of the lesion, a method of trapping has proven itself well. To rid the garden of insects using such methods of resistance:
- Belts for catching insects.
- Spraying trees with herbicides.
- Disinfection of storage rooms.
If the apple fruit moth is very fertile, the control measures need to be combined. It also makes sense to carry out preventive work to prevent infection.
It is possible to catch insects with the help of various devices. Can be used against the pest (apple moth) control measures in the form of a belt for catching. Such devices work due to the desire of the worm to find a secluded place. For the manufacture of such belts, you can use any available material: cardboard, paper, newspapers or fabric. Trapping belts are located at a tree height of up to 30 centimeters from the ground and represent a kind of skirt.
A strip of material up to 20 centimeters wide is wrapped around the trunk and fixed with a rope or rubber band on top, while the lower part of the belt remains in a free state. When overlaying paper, it is advisable to slightly deform or crush it, then you will get many bends, and the caterpillars will freely settle in a similar trap without infecting the fruit. Lining such devices on the tree should be carried out in the last days of May or in the early dates of June. Change such devices should be once a week, carefully destroying the old lining.
Advantages and disadvantages of the trapping method
The advantages of this remedy for apple moth lies in its low cost and simplicity. What could be simpler than to tie a piece of material on a tree trunk? With this method, the codling moth is quickly destroyed and control measures do not allow fruits and trees to be treated with chemical compounds, which makes it possible to get a crop without extra nitrates. Such belts for catching insects can serve not only against the apple moth, they are quite capable of coping with other types of dangerous garden pests.
The disadvantages are the need to constantly monitor the traps. Replacement of the belts should be carried out after the rain. Paper tends to disintegrate under the action of moisture, and film traps are not desirable because of the risk of overheating the bark of the fruit tree on hot summer days.
Spraying trees with insecticidal preparations
The fight against the codling moth in the spring can begin with spraying the garden with special preparations. Among them are "Decis", "Rovikurt", "Sonnet", "Karbofos", "Nomolt", "Sherpa", "Fastak" and their analogues. An apple moth of this type can transfer drugs without harming itself, therefore it is better to carry out each subsequent garden treatment by another means.
Timing spraying trees should be strictly adhered to.
- The first spraying is carried out after flowering, but before the first ovaries appear.
- The second spraying is carried out 12 days after the first. During this period, the apple moth can strike young fruits.
- The third spraying is carried out 10 days after the second.
Spraying should be carried out in the evening because of the pest's nocturnal lifestyle when the air temperature is not less than 18ºС, because at a lower temperature the chemical may not work properly.
Spraying is strictly prohibited during the ripening of the fruit, because it can undergo saturation of the pulp with chemicals, and such a crop is not acceptable for human consumption. In such periods, you can spraying infusions of wormwood or tops from tomatoes. It is the decoctions of these plants have effectively established themselves in the fight against the codling moth.
How to determine what is on your site is the codling moth bred? First, observe whether the butterfly years have increased 2-2.5 weeks after the end of the blooming apple trees. Secondly, take a look at the first ovaries. On holes damaged by insects, small holes appear. Thirdly, if you have not noticed the first two signs, then you can certainly find out when healthy apples start falling from the tree. In a section it is possible to observe the eaten pulp and seeds.
This is a particularly dangerous type of pest.. It multiplies with unprecedented speed. Widely distributed in the south of Russia. There have been cases when in one apple, gardeners found up to 5 larvae of the eastern pinwort. This caterpillar can in a short time destroy the entire crop of apples at your cottage.
This caterpillar does not like heat very much. She feels good during rains and at high humidity. And when the humidity drops to 30%, these insects begin to die en masse.
Apple moth larvae photo
The larva is normal caterpillar pinkish-red hue with small gray dots along the body. It can not be any hairs or fluff. The body also has legs with walking nails. The rear legs are not real, but they look the same. The caterpillar is not very large in size and can reach a length of 2 centimeters.
For the winter, the pest is wrapped in a spider cocoon and placed under the bark, in packages, storages and other places most suitable for comfortable wintering. If your garden is young, then the moth will most likely be located near the root of the tree's neck right in the soil.
Moth on apple: methods of struggle
Measures to combat moths are divided into:
Important to rememberthat all these methods separately will not give any results. To defeat the pest you must use all 4.
Healthy trees, for which ongoing care is rarely subjected to attacks of these pests. But those trees that are exposed to severe frosts, hail, or are overfed with "organic nitrogen" most often become victims of "nasty" caterpillars.
A garden cannot consist of old trees alone. It should constantly sit down new species. Thus, you will increase the number of insects that feed on moths, thereby saving themselves from their worst enemy.
Prevention of the emergence of the apple moth
- It should be twice a year (spring and autumn) to clean the bark of trees and remove the cocoons of butterflies that overwinter there,
- In order to remove the fruits that were affected by the moth, the trees are periodically shaken. All fallen apples must be collected and carried away from fruit trees as far as possible.
- A flowerbed should be broken around the apple trees to attract various insects that feed on pests,
- Moth does not like the smell of tomatoes, so they will not be superfluous near your garden,
- The caterpillars always leave fallen apples and return to the tree in search of new profits. At this very moment they can be caught. Sly gardeners use sticky tape to catch flies. It is simply wrapped around the trunk. Do not forget that different insects will stick to this tape, so it needs to be updated regularly,
- Adult butterflies lure apple syrup, which is prepared according to the following recipe: for 2 liters of water you will need 100 grams of dried apples. They must be boiled for thirty minutes and add yeast and sugar to the syrup. During the fermentation process, this compote is of great interest to butterflies, which costs them their lives,
Chemical control agents
Now the stores are just full of various drugs to combat all sorts of pests. But there are new and not proven drugs. In the case of moths, it is better to trust well proven drugs:
In the evening, a massive butterfly age begins, which means that trees should be processed on a quiet evening without precipitation and strong gusts of wind. The solution is prepared in accordance with all the recommendations specified in the instructions for the preparation. It is necessary to process not only those branches that are located at the bottom or those on which damaged fruits were noticed. Spray should be absolutely all branches and leaves, so as not to leave an insect a place of refuge.
Biological methods of struggle
Many herbsthat can be found in their own garden act on the pest is not worse than the most expensive drugs. Among them:
The first treatment comes at the end of the flowering period of apple trees. Two weeks later, the second treatment of trees is carried out, and another two weeks later the third.
If you have a lot of apple trees in your garden, Between them you can plant crops such as:
The moth is afraid not only of their smell, but also of those insects which they attract - these are horsemen. They are the first enemies of a garden pest. Apples that fall should be immediately harvested and buried away from the garden. Now pheromone bait has become especially popular. These are the traps on which the pheromone of the females is applied. Its smell spreads within a radius of 50 meters. All males flock to it and fall into the trap.
You can also try attract birds to your garden. In the fall, this is done by hanging the feeders, and in the spring of birdhouses. Birds love to eat moths.
Mechanical methods of struggle
There are some ways of struggle that begin to use in the fall. When the entire crop is harvested, experienced gardeners are digging around the tree trunk. In the spring, it is necessary to remove the bark from the trees, which has died off during the winter. In her like to spend the winter various pests. The collected bark should be immediately burned so that the awakened pests do not have time to move to the trees.
Another effective method is use of trapping belts. They are made of burlap and wrapped around tree trunks. Once a week, they should preferably be cleared of caught caterpillars.
Modern pesticides in the fight against pest
The old "grandmothers" drugs had several disadvantages:
- they had no direction of action, they killed both harmful and beneficial insects,
- were dangerous for the gardener himself,
- their dosage is too high
- toxic substances tend to accumulate in the soil and fruits,
- they are afraid of rain as they are immediately washed away from the treated surface,
- their duration is too short and you have to do it over and over,
- to kill a pest, you need to get the drug on his skin or inside.
The superiority of modern pesticides:
- the pest's organism cannot adapt to these drugs,
- not dangerous for beneficial insects, such as bees,
- a tree can be protected for up to 3 weeks, not afraid of rain,
- instant action on the moth and other pests,
- can be absorbed into the fruits and leaves, which leaves the pest no chance of survival,
- destroy the entire family of moths: butterflies, caterpillars and even eggs.
Protecting the apple tree from the moth folk measures
As stated earlier, moth does not tolerate the smell of wormwood. A special infusion is prepared from this plant that will help to get rid of the codling moth very quickly. Spraying is carried out after the end of flowering once a week for a month.
For 1 liter of water you will need 1 kilogram of wormwood. It is filled with warm water. Flooded grass should be infused during the day. Pure infusion must be diluted with water in a ratio of 1: 5 (solution: water).
Also good deters the apple moth the tomato. From its fruits and leaves another effective remedy is prepared against the codling moth.
On 4 kilograms of a mixture of crushed leaves, stems of green fruits of a tomato, you will need 10 liters of water. This mixture must be boiled for half an hour, and then allowed to cool and strain. Next, 3 liters of the resulting broth you will need another 10 liters of water and 50 grams of soap. The resulting solution can be sprayed on trees affected by the codling moth.
Method of catching butterflies using fermenting solutions
How to deal with the codling moth with chemicals, every gardener knows, but such tree protection can have a detrimental effect on the crop. Therefore, you should pay attention to the solutions with the action of fermentation. They are not poisonous and are excellent for the destruction of butterfly pests.
Empty containers are filled to a third with a solution of apple compote or another ingredient that can cause fermentation. To obtain such a solution, you can use whey from milk, kvass bread, beer or decoctions of dried fruit. For the fermentation process, add sugar and yeast to the solution, insist a few hours and pour it into containers. Next, hang the bait on the tree. The strong smell of yeast attracts butterflies, they die in the tank, not having time to make a laying with the larvae.
Replacement of such traps should be carried out as they are filled, but at least every 3-4 days. Otherwise, the fermentation process will end, and there will be no sense from the device.
Measures to combat the apple moth in the fall
If in the spring, despite all efforts, to defeat the pest did not work, then you need to hold a series of activities in the fall after harvest. To prevent larvae from crawling into the bark of a tree, the trunk can be limescaled. Taking into account whitewash no less than a quarter of the tree. The solution of lime should not be made liquid, it is better if all the voids and cracks of the tree are filled with it.
It is good to scrape off parts of the dead bark of the trunk and branches with a scraper and get rid of the waste obtained by burning. In the autumn, a deep tillage of the land should be done around the trees, this will help kill the larvae that overwinter in the ground.
Having prepared the tree for wintering with such methods, it is possible to get rid of the treacherous moth in the spring.
Prevention measures to prevent re-infection
Fruits that have fallen from an infected tree are unsuitable for human consumption. But if the fruit is large and the tree has not been treated with chemicals, then such fruits can be put up for processing, taking into account the complete destruction of the resulting waste.
After harvesting, scavengers cannot leave unprocessed fruits for storage at night. The moth will crawl off due to the principle of its nocturnal activity and there may be a risk of reinfection of the tree or damage to other trees near the house.
A container for harvesting should be chosen from flat and smooth materials, preferably ceramic or plastic. Pest larvae will not be able to hide in secluded corners, as in wooden boxes. After processing such dishes should be thoroughly washed and treated with any disinfectant.
The described methods really contribute to the fight against garden pests. Help to save the crop and prevent damage to trees in the garden. When using preventive measures against infection, the garden will smell sweet and please its owners for a long time.
Плодожорка: что это такое и как ее распознать
Плодожорка – насекомое-вредитель яблони, которое поедает не только плоды дерева, но и уничтожает практически целиком молодые побеги и листву. На первом этапе своего развития плодожорка делает кладку яиц с обратной стороны яблоневых листьев. Они имеют светло-желтый цвет и в диаметре достигают лишь 1 мм.
The butterfly laying off “offspring” has a velvety gray color and small size. She manages to lay more than 80 eggs, of which, after only a couple of weeks, caterpillars appear. Visually they are easy to detect: they differ in small body size (up to 2 cm) and have a bright color with a pinkish tint. By the way, the probability of finding the moth butterfly is problematic, since it appears predominantly at night, but you will find the caterpillar almost immediately.
Having appeared on the light, the caterpillars of the codling moth first eat the foliage, and, after they get a little stronger (in about a week), they are taken for fruit. Inside them, they continue their development up to pupation.
Council There is a very effective way to check for the presence of a pest in a garden plot: a special pheromone trap. You can either purchase it with a capsule containing a low-toxic synthetic pheromone, or make it yourself. If more than 5 copies fell into the trap for a weekly period of time, this is the right signal to start the action.
Pest control methods
There are several methods of dealing with codling moth: chemical, mechanical, folk. Consider each in detail.
Chemical processing of apple trees is considered one of the most effective means of combating the moth. We are talking about insecticides, processing of which should be carried out in the summer period with intervals of 2 weeks (starting from mid-July).
The best effect can be achieved by treating the trees in the period between the beginning of the laying of eggs and the defeat of apple fruits hatched from the eggs by caterpillars.
The following insecticides are most popular: Ditoks, Fozalon, Karbofos, etc. To enhance the effect, the insecticide can be mixed with a fungicide. Among the most successful Arrivo, Proteus and Sherpa are noted. One bucket of fungicide is taken on a bucket (about 10 liters) of water (the insecticide is taken in the amount specified in the instructions). So, we begin processing in early June, then at an interval of 2 weeks we continue processing until it is time to harvest.
In order not to wait for the appearance of the pest, it is possible to carry out preventive measures (and, quite effective) to combat the crop moth:
- removal of falling off parts of the bark (thus depriving the caterpillar of the place for wintering),
- digging the soil between the trees and carefully loosening the soil in the root zone,
- timely removal of damaged / diseased branches, shoots,
- Regular inspection of crown and fruit and timely removal of damaged or sick specimens,
- installation on the trunks of apple trees trapping belts (this will help to quickly and effectively catch all the tracks),
- mandatory sealing of wood cracks.
Council In recent years, a non-trivial tool for the control of the codworm has become increasingly popular - a trichogram cultivated in the laboratory. This insect is parasitic in the moth eggs. Using an insect, you can reduce the level of apple spoilage by 2-3 times.
In order to prevent the saturation of apples with a chemical, you can alternate insecticide with natural decoction. Consider the time-tested folk remedies:
- Infusion wormwood. The treatment of trees should be carried out immediately after flowering. The processing interval is about 10 days. It will be enough 3-4 times. You can also plant bushes of wormwood near apple trees (this will help scare off the pest).
- Apple vinegar. It can be used as bait. In 1 liter of water diluted with 150 ml of vinegar. Hang the mixture on the apple branches. As far as filling the traps with a pest, we change them for new ones.
- Coniferous extract. For the preparation of infusion will need a liter jar of conifer needles. Fill them with 2 liters of water and insist for a week and filter. The concentrated composition is diluted in 20 liters of water and sprayed immediately after flowering.
- Camomile tea. Processing is carried out chamomile extract, prepared from either fresh flowers or dried. On a bucket of water use about 1 pack of dried flowers.
The above means will be quite enough to get rid of the pest on apple trees once and for all. Good luck!
Our results for the protection of apple trees from the moth
During 2016, we carried out 3 treatments with a tank mixture using Lepidocide and BTB, hung out the tar caps in the garden, planted a couple of bushes of tomatoes in tree trunks. In addition, in the garden grow tarragon, mint, catnip. Still all the dangling stepchildren and leaves laid out in the fork of the apple tree branches.
They are not just satisfied with the result, but very happy - the damage was no more than 10%. But we must bear in mind that we badly thinned the fruits in June - we normalized the harvest. The apples and sugars were scored properly, and the size was very good. So try these methods, in a timely manner, carry out preventive maintenance against damage to the fruit by the moth flake.
In the meantime, have not chosen their own methods of protection, feel free to adopt these tips. And save the apples, and chemistry is not inhale. But try not to overload the apple trees with the harvest, otherwise the next year you will not wait for the apples, because the tree will weaken. As you can see, you can pick up a safe defense, and we boldly declare that the struggle with the fruit moth on the apple tree with folk remedies is very effective.
Apple moth: description
The prospect of a damaged crop, a large amount of wasted effort, time and money will hardly please anyone. But all this can be avoided if we adopt proven methods and means struggle with moth on an apple tree. And if, in addition to everything, to learn about the biological cycle of the pest, it will help to multiply the effectiveness of the measures taken to combat it.
Many gardeners up to a certain point do not realize that they have long been settled on the site moth butterfly. And it is not surprising, because it has such an inconspicuous appearance that many do not recognize it as a dangerous pest.
It seems to gardeners that this is a harmless little bug that accidentally flew into the garden. However, over time, they learn that this dangerous color hides a dangerous enemy of fruit harvests.
Butterfly Codling moth is enough large pest. It has a wingspan of about 18-21 mm. On the body are two pairs of wings - the front dark gray color with dark wavy lines that are transverse, and the rear, having a light brown tint. This the pest has a very good disguise - it is necessary for the butterfly to sit on the bark or branch of a tree and fold its wings, and it immediately merges with it and it is almost impossible to distinguish it with the naked eye.
This insect reproduces mainly at night. It conducts its wrecking activity during the period of flowering of trees, which lasts for one and a half to two months. At about 3 days after the appearance, the butterfly begins to lay eggs of milky size 1 mm on shoots, leaves and fruits.
During the season, one individual can lay from 40 to 120 eggs. Over time, white caterpillars with a black head hatch from them. As they grow older, they change their color to light pink. It is the caterpillars that cause the main damage by eating the ovary, gnawing the passages in the fruit and leaving behind the wormholes.
During the season, one individual can give life to two or three generations. The greatest harm to fruit trees is the second.
Hatching eggs caterpillars lead their wrecking activity for 16-45 days. Then they hide in the ground or bark, where they make cocoons for themselves in order to survive the winter in them. In the soil, they arrange their shelters at a depth of 3-10 cm. In addition, they can use plant residues, containers and premises where fruits are stored as shelters. With the onset of spring, when the temperature rises above 10 degrees, they pupate.
Harm from moth
Apple moth can cause considerable harm not only to apple trees, but also to other fruit trees - plums, pears, quinces, apricots and peaches.
The caterpillars can penetrate the fetus through the stalked hollow, damage to the peel under the cover of the leaf. After the worm makes moves in the fetus, there is a rot, which is caused by bacteria that are transferred by the caterpillars on their body. Over time, the fruits begin to emit a specific flavor that attracts wasps.
Adult caterpillars of the last generation cause great damage to the crop, successively gnawing the moves, first in one and then in another fruit and eating their flesh. Only one individual can spoil two or three fruits per season, and sometimes five.
If a damaged apple falls to the ground, moth tries to leave the fruit and after about one or two days it turns out on the trunk, where it continues to spoil other fruits.
In view of the above, it becomes clear what the insect is and how much damage it can do to apples and other fruit trees.
Now it is time to get acquainted with proven ways to combat this pest. Keep in mind that, using only one of them, you can hardly get rid of the codling moth. To achieve positive result, it is necessary to take a comprehensive approach to solving this problem.
Apple moth: control measures
To clear the garden from the moth and its caterpillars, you can use the following ways to fight:
The safest and at the same time effective are preventive actions. If you want to protect your summer cottage from the moth, it is necessary to dig up the soil well in the tree circle every fall.
Thanks to this procedure, cocoons with caterpillars will be on the surface of the earth, where they will die with the first frost.
In addition, do not accumulate plant residues, which can be an excellent shelter for caterpillars.
Twice a year (spring and autumn) need to process the bark of trees. Required carefully inspect trees and remove old areas that can be picked up by pupae for caterpillars. All bark collected from trees must be burned.
A gadget should not be left in a circle where it can rot. Her is necessary collect regularly.
In order to scare away the codling moth, it is possible to grow grassy plants near the plantings that can attract insects - natural enemies of the caterpillars. A rather effective measure is the creation of feeders, which will help to attract insectivorous birds to the garden.
Butterfly moths do not tolerate the smell of tomatoes. Therefore, if you plant tomatoes, mustard or dill next to fruit trees, the pest will bypass your site.
Trapping belts will help you protect the trees from the moth in the summer. To make them, you would need a piece of paper, cloth or burlap, from which you want to cut strips of length 25-30 cm. Then they wrap the trunks of trees at a height of 30-40 cm from the ground. Above the trap must be fixed with a twine, it should be free below.
When the caterpillar tries to reach the fruit, it will begin to climb the trunk and eventually fall into the trap. They need to be regularly checked and retrieved and destroy the insects caught there. For greater efficiency You can spread traps with tracked glue. To protect old trees that are more than 20 years old, you can apply betanaftol on paper or fabric wrapped around the stems of a ribbon of paper or fabric.
It is possible to make a mothbone trap from ordinary adhesive tape, which is used to catch flies. Try to inspect at least once a week. trapping belts and clean them from the caterpillars caught there.
Butterflies can be fought by hand. Knowing that they arrange flights at night, you can turn on a bright light, and after they fly on it, catch them and destroy them. To catch more pests, you can make a trap out of duct tape or sticky paper under a light source.
When it comes time to harvest containers for fruit, you need to previously lay corrugated paper. Caterpillars that will crawl out of the windfall will fall into it. Store fruits preferably in containers without gaps, keep them must be tightly closed. In the future, when the fruit in the containers will not remain, the paper with the tracks should be pulled out and burned. The container must be thoroughly cleaned and treated with boiling water.
Folk methods of struggle
During the time that gardeners have to deal with the moth, they have tried various ways, among which folk remedies have shown themselves well.
For the destruction of the pest, you can use infusions and decoctions based on insecticidal herbs - wormwood, burdock and tansy. You can also use conifer and tobacco decoctions, which have a strong deterrent effect.
The first time the trees are sprayed decoctions and infusions during flowering. In the future, it is necessary to once again process the trees with an interval of 2 weeks. Spray fruit planting is best after sunset in windless dry weather.
For the preparation of tobacco broth take a pound of dry tobacco, add to it 10 liters of water and infuse for 2 days. After that, the resulting mixture must be boiled for 2 hours. The cooled broth must also be diluted with a bucket of water. Before use, 50 g of soap should be added to the solution. Apple is sprayed with this tool in the period of mass emergence of caterpillars.
Insect symptoms and characteristics
The symptomatology of injuries is an enhanced flight of butterflies 12-17 days after flowering, as well as the presence of 1 to 5 or more microscopic holes in the apple ovaries. Also, the appearance of a carrion in the form of apples that are full-fledged in appearance, but on the cut inside of them there are cries and a seedbed chamber.
This butterfly is widespread. the entire European part of the Russian Federation (with the exception of the tundra zone), and Caucasus and Transcaucasia, the Far East and the Baikal steppes, Central Asia, Siberia, Altai, South Belarus and Ukraine. Most harms in the steppe zone of Ukraine, the Russian Federation and in the mountainous Crimea.
Moth chemical preparations
These pest control agents are used only in the event of a massive destruction of trees. In order to determine the moment when it is necessary to treat trees, it is necessary to make pheromone traps and arrange for the site. If more than 5 butterflies get into them in a week, then chemical treatment of trees is necessary.
However, it is still better to do everything possible so as not to have to resort to such a radical measure. First you should try to deal with pests using gentle methods. And if they do not help clean the garden from the moth, you can turn to chemistry. At the same time try to use against the tracks the most environmentally friendly drug.
With a large scale infection of the garden, prepare for process trees will have at least 4 times. The first treatment is carried out during the departure of the butterflies, the second - after 2 weeks, the third - after another two weeks, the last time the apple trees are sprayed after harvest.
To date, the shops offer a large number of different drugs, with which you can clean the garden from the caterpillar caterpillar tracks.
All of them can be divided into three main groups:
Among the drugs in the category insecticide, with the best hand they showed themselves "Decis", "Iskra-M", "Ditox", "Zolon", "Sirocco", "Fufanon". With their help, you can destroy the caterpillars from the exit from the egg to the introduction into the fetus. It is during this period that the spraying of apple trees must be carried out.
In addition, trees can be sprayed cygalotoraamong which the most effective are "Borey", "Gladiator", "Sensei", "Kungfu".
To cope with the moth, you can also use the growth regulators "Insegar", "Match", "Gerold".
Among biological preparations good results show:
If none of the above remedies helped, you can try treating the trees with viral preparations. Among those approved for use against the plant moth can be identified "Madex Twin", "FermoVirin YAP".
Caterpillar - what is it?
The caterpillar is such little fat worm. On the body of pink or pinkish-reddish color with grayish dots there is no hairs or pubescence.
The head and cephalothorax are chitinous, of a reddish-brownish tinge, dark and brightly outlined against the background of an apple. There are real legs with walking claws. On the back, unreal legs also have claws. The length of the trunk tracks sometimes reaches two centimeters. Below you can see what it looks like. moth on an apple tree - photo in different life cycles:
Caterpillar of the codling moth.
Butterfly Codling moth.
What contributes to the survival of the butterfly?
Contributes to its multiplicity, reproduction by several generations per year and secluded wintering grounds.
Wintering places may be:
- in the "old" apple orchards most of the zymovipers' cocoons are located in cracks of the bark, up to 60 cm from the ground plane, and others in the ground near the apple trees themselves, as well as in the places of humus storage, supports, chatals, stakes, various buildings and other shelters located directly in the garden ,
- in young gardens гусеницы перезимовывают, главным образом, в земле у «корневой шейки», на глубине до 8 см, не считая того, что гусеницы плодожорок перезимовывают в упаковочном субстрате, в ящичной таре, в местах для сохранения яблок и оказываются они там с испорченными ими же яблоками.
Химикаты для обработки
Spraying apple trees from harmful insects spend synthetic chemicals based on organophosphates. But you can use neonicotinoids and pyrethroids. Below we look at how to treat an apple tree from moths and when, so as not to damage the crop.
Impact aversectin (Fitoverma) complex: penetrating into the caterpillar with the help of absorption into the outer shells during spraying, or after eating the apples treated with poison, the poison affects the caterpillar nervous system, causing its death.
Is it possible to use a herbicide?
This is typical "Scam" modern shopkeepers. This substance has nothing to do with CWD, but it can ruin the life of the apple trees, because the herbicide is a poison for the plants, and certainly does not harm the caterpillars.
Here is the most effective pesticides, commercially available, and which will be effective in the fight against "worms in apples":
- pyrethroids: Kinmiks, Karate Zeon, Lambda cypermethrin, Sumi-alpha,
- organophosphate: Pyrimifos-methyl, Actellic,
- neonicotinoids (act systemically):
All of the above preparations of the genus neonicotinoids. And all artificial pyrethroids - lipophilic substances, excellently retained by the cells of apple leaves and fruits and partially penetrating into them, guarantee an absolute insecticidal effect on caterpillars. But they are applicable only one month before maturation.
How to sprinkle apple trees from the moth, if the garden was previously treated haphazardly, and the emphasis was placed on any one poison for a number of years? In this case, it is necessary to spray the apple mixtures of poisons. The following tank mixes are most suitable for this:
- imidacloprid + lambda-cyhalothrin,
- Thiamethoxam + Chlorantraniprol.
Compound data (best known Dichlorvos, Fozalon, Karbofos, Fufanon) turned out to be persistent and toxic for nature organochlorine compounds.
These compounds have a small consumption of substance per unit area and a high impact rate on the codworm, which made these substances leaders in the fight against caterpillars.
For the spraying, devices that allow to obtain droplets from 0.23 to 0.53 mm in diameter. Such a "fog" tightly and quickly envelops a lot of leaves and shoots of apple trees with the beginnings of apples, and reduces the consumption of poisons.
Besides he bad wind and by this significantly reduces the risk of poison on other cultures in the country.
Terms of spraying
Timing when spraying apple trees from the moth is hard differ for each region of the Russian Federation and for every spring. Therefore, it is meaningless to indicate them, since they are determined on the spot by the beginning time of the flight of adult butterflies in the spring and its intensity.
The greatest effectiveness in spring processing showed organophosphate preparations. They destroy the caterpillars during their birth, and the pest does not have time to reach the small apples. The most effective will be:
During the mass flight of butterflies apply poisons "Insegar", "Dimilin", "Gerold". These drugs belong to the group of growth regulators and insects. Females lay eggs on the poisoned surface, so the caterpillars are waiting for imminent death.
Also suitable combinations of synthetic poisons, for example, Thiamethoxam + Chlorantraine.
Dates in the fall
As soon as the leaf fall, In the autumn you can splash and clean the apple orchard. They spray the crowns with poisons and scrub the trunks and branches from the old bark. Previously, these terms are not worth doing.
Spraying the garden after the leaves fall.
The first period, when treating apples from the tree moth, is the moment of early spring summer. Before the apple trees themselves begin to bloom.
The processing period consists of two parts - before flowering and after. It ends when the apples begin to “pick up color”.
How often to spray?
In places where the moth forms 2 “waves”, on winter apples 4 sprays are necessary, and on summer two.
In conditions where three generations of the codling moth are developing, 5 sprays for summer and autumn varieties and 7 for winter varieties are recommended.
Time of processing:
- quiet cloudy day and no wind
- predawn or sunset hours.
Because in the heat of drugs reduce their "toxicity", and the wind will reduce the quality of processing.
Ecological methods of struggle
It is assumed that these methods for combating this insect and its caterpillars on apple trees least dangerous for nature. The most effective will be only trapping belts, pheromone traps and bio-insecticides.
Below we consider the most effective ways of how to get rid of the moth on an apple tree using environmental methods.
The base in such traps is created as a pheromone formulation. "SR-MK". It is important that pheromones are used in all apple orchards simultaneously. And the use of traps only in some garden plots can only cause the accumulation of a large number of males of the codling moth in these gardens and this will have no effect.
To destroy the caterpillars of this insect do "Belt" of canvas, then they only catch, or canvas with poisonthen these are killing belts, and they are set up a couple of days before the first generation of the first generation of caterpillars comes out of the fruit, when the worm has a maximum size in the drop - you can wind the belts on the bole.
Inspect Belts need once in two weeks and all pupae and caterpillars cleaned into a container with a solution of liquid soap. And the killing belts do not need to be viewed. They are soaked with "FOSami" every 10-12 days. And after the impregnation is simply repeated.
Catcher belt smear special glue mix or simply medical petroleum jelly.
This glue is prepared from 10 parts of resin, 1.5 parts of rosin, 1.5 parts of paraffin and 2 parts of garden warrior. This is all slowly heated on the fire to paste. If the mass, while cooling, sets too quickly and weakly sticks, then it is heated again and 1 part of melted fat or oil is added.
Even for lubrication, you can prepare a mass of 450 grams of wax, 290 grams of rosin and oil to a liter, better than vegetable. Slowly heat the first two components first, and then add the oil in such a way that after cooling, on a spoon, the mass would be sticky, but it would not flow down.
Integrated protection of apple trees from moths is the best answer to the question "how to protect an apple tree from the moth". Such protection is a special approach to the “collective use” of all available methods of deterring or exterminating the codling moth, encompassing mechanical, physiological, biological, biogeocenotic, agrotechnical, chemical methods of controlling and controlling the number of caterpillars used with the main purpose - this the lowest cost of funds and minimal damage to nature to reduce the number of moths on apple trees.
Starlings on an apple tree eat caterpillars?
Although the Internet and walking information that these birds feed on the tracks of this pest insect, but it is not. They are massively pecked only different types of tits, and then at the time of their exit from the apples and creeping into wintering places.
Flowers that protect the apple tree from worms
Another “panacea” for worms in apples from the Internet, especially distributed by supporters of “BIO-farming”, is planting special types of flowers under apples that frighten and kill the pest.
It is a pity, but this method cannot give anything but disappointment and the harvest missing from the pest, for biology is not “conducted” on fashionable trends, and the butterfly does not perish only by the smell of plants.
Regular processing of apple trees from the moth in the summer will provide a lot of delicious apples in autumn and winter!
Apple moth - one of the most famous pests that can cause serious damage to the crop. In order to destroy the butterflies and caterpillars of the moth, gardeners use various methods and means of control.
but most efficiently combine traditional methods with chemicals, which in most cases help to achieve a positive result.
Even if you do not know how to deal with the moth on apples, it is still better not to bring up to such and prevent such situations. To do this, it is necessary to engage in prevention and every year after harvesting to dig the ground around the circle of the circle, to prevent the accumulation of plant debris that insects can use as shelters, and to regularly drop the carrion.
