The pest is able to destroy the entire healthy plantation in the shortest possible time. The beetle quickly eats not only the tops of potatoes, without which the culture cannot develop normally, but it can also appear on peppers, tomatoes, eggplants, destroying plants at the root. This is due to the need for timely use of the poison.
With the appearance of striped insects on potatoes, it is necessary to immediately plan methods for exterminating the pest. For this gardener, it is important to familiarize yourself with the modern range and choose a product that will give the best result. All means of dealing with the Colorado potato beetle are divided into categories according to the method of processing and toxic substances in their composition:
- tuber disinfectants before planting (they do not harm fish or bees, but destroy pests in the soil and on its surface),
- insecticide sprayers of young shoots (they quickly kill any pests, but are dangerous for fish and beneficial insects),
- combined preparations that include several active substances (possess fungicidal and insecticidal effects, in addition, act as sprayers and disinfectants, leaving no chance of disease),
- biological products (they do not harm the soil, plants, animals, fish, but are successfully used to destroy the Colorado beetles, requiring, nevertheless, a large number of treatments),
- folk remedies (minimally effective compared to other groups of funds, but affordable and safe for harvest).
Preparations against the Colorado potato beetle
There is no alternative to chemical preparations for the treatment of large areas occupied by planting solanaceae, or with a large number of beetles on plants. Any insecticide copes with hordes of insects in 1-3 treatments, and both adults and larvae, eggs, are killed.
Despite differences in the class of such substances, pesticides have a similar principle of action, destroying the Colorado potato beetle by the contact-intestinal method. However, the mechanism of ingress of poison into the body of the pest and contact with it is different from the way it treats planted plants, and therefore the means have different uses.
Prevention of the emergence of the Colorado potato beetle
The best remedy for the Colorado potato beetle to start with is prevention. The young Colorado potato beetle is much more dangerous than adult individuals. They are able to destroy a large area of plants in just one day. Therefore, it is important to prevent their occurrence as much as possible.
Good scare pests fresh or rotted walnut leaves. In the autumn they need to be scattered throughout the site, and then dig up the garden. Plowing the land on the eve of the cooling will allow to destroy a significant part of insects that did not have enough time to go deep enough in preparation for wintering. Throughout the winter, the bed must be evenly scattered wood ash, which has a detrimental effect on leaf beetles and enriches the soil with useful vitamins (phosphorus, potassium).
In the spring, before the emergence of shoots, in glass jars (0.5 -1 l) you need to put a few pieces of raw potatoes or its skin. Vessels need to be buried flush with the ground surface, evenly distributing them throughout the bed. Periodically it is necessary to check such traps and destroy pests caught in them. It is possible to lure and collect insects by this method after harvesting.
During the growing season it is necessary to periodically inspect the tops, and in time to make manual assembly and destruction of pests. In addition to the pests themselves, it is necessary to remove their larvae. And if the beetles on the potatoes are visible quite well, then sometimes it is not easy to detect eggs. Insects usually debug them on the inside of the leaves.
The Colorado beetles are well developed snuff receptors, so they do not like to live in areas where strong odors predominate. To create such conditions in their garden, some growers alternate potato rows with planting other crops. Among the most "unloved" pest - onions, garlic, beans and beans.
Some plants produce a sharp aroma only during flowering. They decided to upset potato plantations around the perimeter. Calendula, coriander, violet and hemp have good deterrent properties. True, the cultivation of the latter is prohibited by law.
Manual destruction of the Colorado potato beetle
An effective remedy against the Colorado potato beetle is its manual destruction. Joy this action does not deliver, but the result brings.
Mechanically, beetles are destroyed when there are few of them: as soon as seedlings appear or seedlings take root, it is necessary to carefully examine not only the plants, but also the soil around them, in time to detect pests and collect them in a jar of saturated salt solution or kerosene (or take it out plot and burn).
This daily hard work, which is the safest, combined with other methods of dealing with the Colorado potato beetle, but it can give a good result.
Agrotechnical ways of dealing with the Colorado potato beetle
An important method of dealing with the Colorado potato beetle is the proper management of garden economy. Potatoes and other vegetable crops (desired for a pest) should return to their former place no earlier than 4-5 years.
Consequently, a crop rotation (crop rotation) is needed, which would optimally regulate the correct alternation of vegetable crops, contribute to the timely processing and preparation of the soil for planting or sowing the next crop.
During the growing season, it is necessary to keep the potato fields or beds in a clean state from the weeds, using the latter as mulch after loosening.
Biological ways of dealing with the Colorado potato beetle
The safest way to fight against the Colorado potato beetle is the safest and most promising for your garden. It is based on the use of its natural enemies to the detriment of an insect - birds, microorganisms, predatory and parasitic insects.
The best remedy for the Colorado potato beetle - for this you need to locate in the garden plot the maximum variety of crops that attract natural enemies of the Colorado potato beetle (birds, ladybugs, ground beetles and others) to the garden.
Chemical methods of dealing with the Colorado potato beetle
The chemical method involves the treatment of plants with insecticides during the second age of the larvae and with the mass appearance of young beetles.
But the Colorado potato beetle has a high resistance to pesticides and quickly adapts to them. Modern systemic insecticides are not addictive and show high efficacy in pest control.

The Colorado potato beetle belongs to the group of insect-leaf beetles with an oval, convex, shiny, yellow-orange body 8–12 millimeters long and 7 millimeters wide. There are black stripes on the elytra, and black spots on the predspinka. Webbed leaves are well developed.That allows the beetle to overcome huge distances in flight.
The larva of the Colorado potato beetle 15–16 millimeters long has a black head and two rows of black spots on the sides. At the initial stage of development, the larva is colored dark brown, however, as it grows further, the color becomes bright yellow or pinkish. Eating leaves, tiny individuals acquire a carrot color, which is associated with the inability to digest all the carotene pigments.
The wintering of such a dangerous creature for solanaceous crops occurs in the soil at a depth of 20–50 centimeters. As soon as spring comes, and the air temperature rises rapidly, insects begin to emerge to the surface, eating sprouts. Mating and laying eggs takes place on the underside of the leaf plates. In a day the female lays from 5 to 80 eggs, and for the season - from 300 to 1000. The youngest larvae consume the pulp of leaves from the lower side, while older larvae are able to eat the entire plate, with the exception of the median veins.
Later larvae are rapidly spreading and moving independently to other plants. After 2−3 weeks, they can burrow into the soil to a depth of 10 centimeters and pupate. After 10–20 days, adult beetles form from them, which either reach the surface or fall into diapause until spring.
Insect lives for one year, although some individuals grow to two or even three years. If the pest senses danger, it does not fly away, but falls to the ground, pretending to be dead.
Currently, there are many effective tools for the parasite. To successfully get rid of the problem, you need to use some techniques, including:
If crops are provided with proper care, which will stimulate more productive growth and development, the plant will develop strong immunity. As a result, the representatives of the nightshade become more resistant to damage, so the conditions for the development of the pest deteriorate. It is no secret that the high risks of the appearance of beetle colonies are associated with many mistakes of gardeners. To prevent them It is important to consider such recommendations:
- When choosing the right grade, choose poorly eaten grapes,
- For planting should be used only high-quality and healthy potato tubers,
- Plant care should be timely and competent.
It is possible to destroy the attack mechanically in those cases if the number of individuals is small. As soon as the first shoots appear from under the ground, or the seedlings begin to take root, a full inspection of the plants and the soil should be carried out. If you managed to notice the pests, collect them in a jar of saturated kerosene or saline.
When looking for the most effective and safe way to handle the garden, pay attention to the biological one. He is able to destroy insects using his natural enemies, including birds, microorganisms, predatory and parasitic insects.
If we talk about chemical processing, it consists in the use of highly effective insecticides at the stage of development of the larvae of the second age, as well as with the mass appearance of young individuals. However, you should understand that beetle has high resistance to pesticidesand over time it begins to adapt to toxins. But the fact is that these drugs are addictive. But if we talk about systemic insecticides, they have excellent efficacy and are not addictive.
Chemicals and preparations
As for the most highly effective means to combat such a common pest, they include the following drugs:
- Actellic. Refers to a broad-spectrum insecticidal drugs. It can be used no more than twice per season, guided by a dosage of 15 grams per 10 liters of water. For ten square meters you can use 1 liter of solution,
- Arrivo. It is a twenty-five percent emulsion concentrate and a highly effective insecticidal agent of contact action. The drug is characterized by high efficiency with minimal consumption of the active substance,
- Decis. A very popular solution for processing solanaceous crops. It is not afraid of rain, does not disintegrate in the soil, does not accumulate and freely interacts with other drugs,
- Itra-vir. One tablet of the drug should be dissolved in 10 liters of water, and then served in a ratio of 1 liter of solution per 10 square meters of the area with solanaceous cultures. The allowable number of procedures - 1-2 per season
- Karate. It is a 5% emulsion concentrate created by English gardeners. To prepare a highly effective tool is not very difficult. It is enough to take 10 liters of water and add 1 gram of Karate or 2 grams of Kinmiks to them. Insecticides are used no more than twice during the growing season,
- Sonnet. Treats contact preparations of the American production. With its help, one-time processing of cultures is carried out at the stage of rapid development of larvae,
- Sumicidin. It is produced by a Japanese company and is very popular. You can use it no more than two times during the growing season in the form of a solution. Gardeners dilute 3 grams of a substance in 10 liters of water,
In addition to numerous chemicals and drugs, many domestic gardeners prefer folk remedies. This is due to the high risk of poisonous substances in our stomach in the case of the use of chemicals. Fortunately, people have learned to deal with the problem more loyal and secure methods. Among them - mechanical pest collectionHowever, if we are talking about extensive plantings, then there is no such solution. It remains to find something as non-toxic as possible, but very effective. Highlight the most popular recipes for effective formulations from the pest:
- One kilogram of fresh leaves and green walnut fruit, pour them with 10 liters of boiling water and insist for 7 days under the lid. Then filter,
- 300 grams of dried leaves and walnut shells are placed in a ten-liter bucket of boiling water and left under the lid for a week,
- 1 kilogram of crushed white acacia brew insist in 10 liters of water for three days, then filter,
- Half a bucket of poplar leaves is filled with water and boiled for 15 minutes, until a 10-liter volume is formed. After a three-day infusion the solution is filtered,
- 100 grams of birch tar and diluted in a bucket of water. With the prepared solution we process the culture for a week, repeating the procedure three times,
- Insist half a kilogram of sunflower flowers in a bucket of water for three days, and then filter,
- 1.5 kilograms of celandine fill with hot water. Then we insist under the lid for about three hours, filtering and pouring into the solution a one and a half percent solution of calcium chloride,
- 300 grams of onion peel filled with hot water 70−80 degrees Celsius. After daily infusion under the load, the solution must be drained,
Ways to fight
Experienced gardeners are accustomed to fighting the beetle with radical methods. At an early stage of development of the larvae, it is necessary to scatter around the site of cutting potatoes, which were previously kept in chloroform solution. Beetles eat the sprayed product, causing them to die en masse. So you will be able to free the selected area from the rapidly developing colonies of the Colorado potato beetle, so by the time of landing the territory will be safe. The procedure is repeated a week before the emergence of shoots and in the autumn, after harvesting.
It is known that the pest is very afraid of the smell of rotting onion peels, so at the landing stage it is placed in each well, along with the ashes. Grown bushes are not susceptible to insect attack until the end of the flowering period, and in fact after this the beetle is not capable of causing great harm to the potato.
Protect the potato from the beetle by mulching between rows. To do this, they lay out the straw, which perfectly suppresses the weeds and allows the soil to maintain normal moisture for quite a long time. This will protect the tubers from the sun and create favorable conditions for the reproduction of the biological enemies of the beetle, including ground beetles, ladybirds and praying mantis.
A very effective way to fight a bug is to grow some plants that have a detrimental effect on it. Among such green spaces:
And then the insect will not even look at the site. Правда, на этапе созревания семян растения лучше удалить, иначе они массово распространятся по участку.
При химических методах обработки следует остановить свой выбор на тех препаратах, которые были перечислены выше. By the way, many modern gardeners highlight the special effectiveness of the French means “Colorado potato beetle NO”. It is characterized by high efficiency and the absence of dangerous effects on the human body. To significantly reduce the number of pests, it is enough to spend three treatments per season.
If you intend to overcome the beetle on eggplants, then in this case it makes sense to use all sorts of traps and special devices, placing them around the perimeter of the beds in early spring, after the soil warms up. As already mentioned, the method of scattering potato pieces treated with the corresponding substance is not bad. You can also pour a bunch of waste and wait for the appearance of pests. Then it needs to be poured over with gasoline and set on fire.
If the seedlings began to be covered with the first ovaries, the use of toxic chemicals is strictly prohibited. The only way out of the situation is to hide the seedlings from the pest by covering them with plastic bottles that have their throats and bottoms cut off. Early spring beetles are very lazytherefore they do not fly or travel long distances. To get close to the stalk, which is reliably protected by plastic, is almost impossible.
Not bad manifests itself another method. It involves the use of a fence from a polyethylene film 50 centimeters high. It is known that the females of the Colorado potato beetle very rarely fly, and the males do not fly to places where there are no females, therefore such actions will protect the bed from the pest for a short period of time.
It is possible to save eggplants from such a dangerous pest using mosquito nets. To do this, it must be planted on each bush, as a result of which the plant will receive the optimum amount of light, air and moisture, but it will become protected from insects. The bottom edge of the cap is covered with earth.
You can protect the culture from the appearance of beetle colonies by scattering mowed grasses to the height of the bushes. Dangerous smell can scare off beetles from eggplants. Planted around the perimeter of the beds those plants that scare the beetle with its smell.
The most effective method of dealing with the beetle is a mechanical collection with subsequent destruction. It is impossible to do with chemicals alone, since they are highly toxic. In addition, over time, the insect produces strong immunity to the active substances of individual drugs, so the chemicals lose their effectiveness.
Pest control of the Colorado potato beetle
The Colorado potato beetle is known to almost everyone, quite small in size (about 1 cm), it is characterized by a striped color and a rounded body. An insect can go into the soil not only in winter, but several times over the summer. The fact of this so-called rotation of the insect is verified, so one or two pickles will not be enough to completely destroy it. It is worth knowing that in one clutch the female of the Colorado potato beetle is capable of producing 500-600 eggs, which, in order to turn into a full-fledged pest, last one month. That is, from spring to mid-summer, the number of the beetle can increase 150-200 times. The sight, when the underside of the leaves is littered with bright orange clutches of eggs, is amazing. After all, through a small period of time, these eggs will appear gluttonous larvae, which in a moment will eat potato bushes.
After a month of active feeding, the larvae will descend into the soil, pupate there, becoming young bugs. They will continue to destroy the crop, eating the remains of the tops after the larvae. If no measures are taken against the beetle, or the measures applied do not work on it, then it will calmly wait for frosts, go deeper into the soil, where there may be more than one year waiting for new potato plantations.
What is the most effective remedy for the Colorado potato beetle? How to get rid of the striped pest and save the crop? Effective remedy for the Colorado potato beetle when planting potatoes has a warning nature and is aimed at insect deception. In the aisle, it is recommended to lay out potato trimmings as sprouts or plant sprouted potato tubers in early spring. Waiting for the striped guests, crawling to eat "snack", you can safely collect and destroy them.
It is recommended to spud the emerged shoots, which will save young potatoes from a beetle for 5-10 days, and also determine the saving of the tops of the larvae that could lay thousands of eggs on the leaves.
An effective remedy for the Colorado potato beetle is its manual destruction. It does not bring joy, but the result brings. From the green mass of the potato, adults should be collected, laying eggs and larvae, carried outside the site and destroyed. This daily work, which is the safest, in combination with other methods of struggle can give a good result.
Biological preparations against the Colorado potato beetle
An effective remedy for the Colorado potato beetle is the use of biological agents that are dangerous to the pest and are safe for humans, the environment and animals. Well established "Fitoverm", "Agravertin", "Bitosibaktsillin", "Bicol." It is enough for the season to spend 2-3 sprays with a break of a week. After processing, the larvae of beetles become inactive, stop eating. This is explained by the penetration into organisms of pests of bacteria, which, developing inside them, hinder the development of the beetle itself. "Fitoverm" immobilizes the pest, which after 3-6 days after treatment dies. These preparations are powerless for laying eggs, therefore it is recommended to use them during the period of appearance of the larvae, and then repeat.
Poisons in the fight against the Colorado potato beetle
The most effective remedy for the Colorado potato beetle, the reviews of which are very contradictory, is a poison of chemical origin. Gardeners use it as an extreme option, if the rest, more harmless to the plant methods, were powerless. Treatment should be carried out in the event of a massive onset of the beetle. Such drugs as Aktara, Marshal, Inta-Vir, Tsimbush, Arrivo, Karate, Regent, Zolon, Rovikurt, Iskra and other. Using chemicals, it should be understood that their action may spread to other plants, and in a negative context. Be sure to use protective equipment and follow the instructions, because exceeding the dosage will lead to the accumulation of harmful chemicals in the soil and tubers of the plant. Processing should be done in calm weather, preferably in the morning or in the evening (in order to avoid harmful fumes during the heat), using special garden sprayers. You cannot use brooms, watering cans and other available materials as a replacement. After spraying in gardening work, a two-, three-day break should be taken. If weeding of plants was performed, then weeds should not be fed to poultry in any way, but destroyed. Poison against the Colorado potato beetle should be constantly changed due to the easy addiction of the insect.
As the Colorado potato beetle conquered domestic territories, gardeners carefully thought out methods of dealing with it without the use of chemicals. Some of them proved to be ineffective, others have proven themselves well and are successfully used in private estates.
Wood birch resin is a fairly effective remedy for the Colorado potato beetle. Reviews of gardeners are mostly positive. Adult bushes of potatoes are recommended to be sprayed with birch ash per 10 kg per hundred. This is quite a lot, but at least it is not harmful for the plant. Both adults and larvae die from such a popular preparation. Ashes can also be sprinkled on the soil under the bushes of a plant, in which case there is little chance of escape from the beetles that hide in the soil.
Laundry soap - an effective remedy for the Colorado potato beetle
Potato bushes can be sprayed with a solution of soap. To do this, you should dissolve the crushed soap bar in a bucket of water, you can also add 2 liter cans of wood ash there. The resulting composition insist 15 minutes, then immediately use.
With the Colorado potato beetle you can successfully fight with the help of ordinary calendula, which for some reason is afraid of the Colorado potato beetle. This fragrant flower is recommended to be planted around the perimeter of the potato plot, as well as inside the beds themselves.
An effective remedy for the Colorado potato beetle is wormwood. It is required to cut a few bushes of a plant, cut it and fall asleep in a standard bucket, filling it by a third. Green mixture pour boiling water, mix, cover and leave for several days. Further, the composition is required to filter and use for spraying.
In the fight against the Colorado potato beetle, decoctions from onion peel and such plants as hot pepper, tobacco, garlic, burdock showed their effectiveness. Spraying should be carried out in the early morning hours or evening. This is required to prevent rapid evaporation of the drug from potato tops. Such treatments should be weekly and terminated 20 days before harvest.
Useful tips for saving potatoes
In order to maximize the protection of potato plantations from the pest should follow a number of rules:
- observe crop rotation,
- place plots for planting potatoes at a remote distance from solanaceous and pumpkin crops,
- in the autumn to make a deep digging of potato beds, and during the growing season - regular weeding between the rows,
- spud the beds, you should fill up the lower leaves higher - this contributes to the destruction of egg-laying on them,
- mulch the soil with needles or straw, which will not only ensure effective weed control, protection from direct sunlight and preservation of moisture in the soil, but also create favorable conditions for insects - potential enemies of the Colorado potato beetle (these are ladybugs, praying mantis, ground beetles),
- after harvesting, the plot should be left absolutely clean, bringing all plant residues to the fields.
Insecticides used by the Colorado potato beetle
Modern toxic chemicals have a complex effect, destroying dozens of species of pests in one application. These preparations are lethal for caterpillars, worms, larvae, ticks, and adult insects. Synthetic organic compounds are used to destroy the Colorado beetles: imidacloprid, cypermethrin, thiamethoxam, malathion, permethrin, deltamethrin, chlorpyrifos, and a number of other substances.
Imidacloprid - a potent substance, it is included in the following drugs:
- Golden Spark,
Thiamethoxam - active substance of toxic chemicals:
Cypermethrin - active ingredient of the following means:
Acetamiprid - the active ingredient of toxic chemicals:
Malathion - the basis of the following drugs:
Deltamethrin - active substance of such preparations as:
Intestinal, contact and intestinal-contact insecticides completely destroy the Colorado potato beetle in gardens, gardens and flower gardens. Systemic pesticides, penetrating inside plants, and fumigators are ineffective in combating this pest.
Konfidelin - toxic chemical contact action. This tool can be used to rid the land of the Colorado potato beetle at any time during the growing season. The chemical is also used against thrips mites, aphids, shovels.
The active substance Confidelina - imidacloprid. The product is available in 1 ml ampoules and 10 ml polyethylene bottles. The concentration of iminacloprid in 1 ml of suspension is 0.3 grams. The working substance of the chemical does not burn the leaves and fruits of plants.
The contents of the ampoule are mixed with 5 liters of water. This is enough for spraying 200 square meters of vegetable garden. Confideline keeps well on the leaves of vegetables and protects plants from new generations of pests for two weeks.
Confideline causes perforation of the stomach walls of insects and beetles, the larvae and caterpillars stop feeding, immobilize and fall to the ground within 1-3 days. Imidacloprid also disrupts the nervous activity of insects.
Aktara destroys not only the larvae of the Colorado potato beetle. The drug is used against the wireworm, whitefly caterpillars, thrips ticks, flea beetles, cabbage moths. The active ingredient of Aktara is the toxic chemical thiametaxan.
Aktar is produced in the form of a suspension, the liquid is sold in bottles (9 and 250 ml). There is also a granulated preparation (in plastic bags). Each package contains 4 grams of granules. For processing from the Colorado potato beetle bred:
- 1.2 g of granulated Aktara per ten-liter bucket of water,
- 0.6 ml suspension in the same volume of water.
Five liters of working fluid is enough to handle one weave of vegetable garden. The drug protects plants for 2-4 weeks (the less rain, the better the protective layer is preserved).
This chemical is used in greenhouses, greenhouses, in the open fields they poison the Colorado potato beetle. The killer has a paralyzing effect on the larvae of three dozen insects, including the whitefly, scoop, moth, aphid.
Suspension of the drug Killer is sold in ampoules (1.3 ml) and in plastic vials (10 ml). The active ingredients of the chemical Killer - chlorpyrifos and cypermethrin.
Cypermethrin has a contact effect on adult beetles and destroys their nervous system. Pests become inactive, cannot fly, multiply and make new clutches. The insecticide is valid up to 30 days, the greatest effect is observed in the first or second day after spraying.
Chlorpyrifos causes insect paralysis, and as a result, the larva immobilizes and falls to the ground in a few hours. Pests do not die instantly, it happens after eating leaves covered with pesticides. The larvae disappear from the tops 2 days after treatment.
The killer does not wash off the surface part of the plant for up to 70 days. The standard dosage of the drug is indicated on the package:
- For the treatment of the ground part of the plant, one ampoule (1.3 ml) is added to water (8 liters). This volume of solution is sufficient for irrigation of one 0.1 hectare of vegetable garden.
- For the treatment of planting tubers (25 kg) in a liter of water, dilute 10 ml of killer. The chemical is applied with a spray.
After irrigation of the garden with poisonous chemicals, the Killer crop cannot be harvested within 45 days.
Spark double effect
The active ingredients of the pesticide are the insecticides cypermethrin and permethrin. In the bag is one tablet. Experience has shown that the spark double effect acts well on larvae of all ages and adult Colorado beetles. This chemical is used against 60 species of insects and their larvae.
The package contains one tablet weighing 10 grams. It is diluted in a small amount of water, the solution is filtered and poured into a bucket. The volume of the liquid while stirring is adjusted to 10 liters. For processing 10 square meters of a kitchen garden use 1 liter of an insecticide.
The chemical is sprayed with a sprayer or hand sprayer. The larvae stop eating and moving within an hour after treatment, as cypermethrin destroys their stomachs. After spraying Spark potatoes can be eaten in three weeks.
Potassium-containing substance, which is part of the tablets, has a healing effect and allows plants to recover quickly after the application of an insecticide.
The active ingredient of Mospilan is acetaprimide. The drug is produced in powder form. There are 1, 50 and 1000 grams of Mospilan for sale. The concentration of insecticide is 200 grams per kilogram of powder.
For irrigation of potatoes in 5 liters of water dissolve from 5 to 8 grams of Mospilan. This amount of the drug is enough to process 2 acres of plantation.
The larvae stop eating and moving through the leaves within an hour. They die within a day. New clutches and adults of the Colorado potato beetle do not appear on the treated areas for 3 weeks.
Potatoes can be dug and eaten one week after being treated with Mospilan.
The active substance is organophosphate insecticide malathion. Karbofos for the destruction of garden pests produced in the form of an aqueous emulsion. The concentration of the active substance in the suspension is 45%.
The drug is packaged in 5 ml ampoules. To prepare the working solution, the contents of the ampoule are diluted in a bucket of water. Karbofos is applied to plants with a garden or hand spray.
Malathion is a contact poison, it enters the body of pests and disrupts nervous activity. As a result, beetle larvae die. Plantings can be treated with carbofos once in ten days, the last irrigation is carried out 20 days before harvesting.
This tool belongs to the group of pyrethroids, its active ingredient is the insecticide deltamethrin. The chemical is made in the form of tablets weighing 2.5 grams. The concentration of the active substance is 2.5%. AT one pack contains three tablets.
Deltamethrin disrupts the processes involving potassium and sodium, the insect nervous system is overstimulated and the respiratory process stops. The chemical infects the larvae when released into the stomach and on the skin.
For the manufacture of a working solution of 5 grams (2 tablets) funds are dissolved in 10 liters of cool water. Этого количества жидкости достаточно для обработки 0,2 гектара огорода. После применения ФАС сохраняет защитные свойства в течение 2 недель.
Правила применения инсектицидов
При применении любого инсектицидного препарата следует придерживаться общих правил. Это поможет получить максимальный эффект от ядохимиката.
- The garden is sprayed early in the morning or after sunset, in dry and calm weather.
- Working solutions are not stored, they should be spent on the same day. Remains of liquids disposed of.
- The treatment is not carried out in the protected zone of water bodies (closer than 100 meters from the coastline).
- After spraying, the larvae stay on the leaves for 1-2 days and it seems to the gardener that the toxic chemical does not work. Therefore, many gardeners allow an overdose of the drug. This can not be done, on the packages indicated the maximum consumption of the solution per hundred or square meter.
- If the package does not have clear instructions on the interaction of one insecticide with another, the preparations are not mixed in order to avoid unwanted chemical reactions.
- The treatment is carried out at a temperature of 12-24 degrees Celsius.
- If the drug gets on the skin, mucous membranes, stomach, or eyes, the poison from the Colorado potato beetle can harm health. To prevent this from happening, gardeners must follow the following rules.
- Do not eat, drink or smoke during work.
- Spraying is carried out in protective clothing, rubber gloves, closed shoes and a respirator.
- In the garden during processing should not be children and pets.
- In case of poisoning with pesticides, you should contact the clinic or call an ambulance.
Insecticides that effectively destroy the Colorado potato beetle are substances of little danger to humans and animals (classes 3 and 4 of danger). But they can not be used when there is an active flowering of fruit trees, shrubs and herbs of honey plants on the site and in its vicinity. Any contact with insecticidal preparations leads to the mass death of bees.
General issues of struggle with the Colorado potato beetle
Thus, the only acceptable way to combat this insect is to exterminate it with the help of specialized insecticides.. The fight against this pest must take into account the peculiarities of the life cycle of the beetles, this is how it will achieve maximum efficiency from all the means that are planned to be used.
Consider the life cycle and features of the development of the beetle in more detail:
The beetles hibernate at depths of 30 to 50 cm. Those of them that did not freeze in winter come to the surface, begin to feed on young shoots (not necessarily solanaceous) and mate. Moreover, if the female beetle mated in the fall, in the spring, leaving the hibernation, it immediately lays its eggs.
Beetles emerge from their winter hiding places when frosts are no longer foreseen. Usually, this happens when the air temperature stabilizes around + 12-15 ° С and there is no serious precipitation expected. The peak of such an outcome falls on the last decade of April - the first decade of May.
Colorado potato beetle eggs
In one day, the female beetle is able to lay several dozen eggs., during the entire life of the female, the number of eggs can reach about a thousand (according to some information - seven hundred).
Thus, the livestock of only one female can turn into a center of distribution of beetles of a regional scale. In the northern regions, beetles rarely survive one generation, however, in the south (Kuban, Rostov and Astrakhan regions, Kazakhstan, Ukraine, Moldova), there may be two or three generations of Colorado beetles, depending on the temperature and duration of the warm season. This means that, in fact, preventive measures to control the beetle should begin at this stage already.
The larvae come out of the eggs already on day 5, under unpleasant weather conditions - on 15. In order to successfully deal with pests at this stage, you need to prevent the emergence of a large number of larvae and destroy the maximum number of insects before they lay eggs.
The case when the measures taken were useless or untimely
The larvae will gain a mass of about three weeks, then they burrow into the ground and turn into pupae. The pupae either have time to turn into adult insects and go out at the end of the summer, or they spend the winter until next year, and then turn into adult individuals next spring. Adult beetles in search of new feeding places or meta wintering can fly up to 10 km per day.
They can also fly!
The life cycle of the Colorado potato beetle is several months, however, these insects have the unique ability to enter the state of diapause - a multi-month hibernation, which can reach 3-4 years.. That is why beetles become capable of producing offspring immediately in the middle of spring (from adult fertilized overwintered females), and this is the reason for the impossibility of their total elimination. Well, in any case, is not yet ...
Modern means against beetles created by the chemical industry are quite effective and the state of the matter is now much better than 20-30 years ago. It is possible that soon there will be a universal method for the complete extermination of the Colorado potato beetle.
Specialized insecticides against this insect species can be classified according to several parameters. In general, funds from the Colorado potato beetle come in the following classes:
- Means of narrow specialization. Their use is limited to only one form of insect. Some tools help only against the larvae, some - only against adult, formed beetles.
- Multipurpose or universal. Such tools are capable of infecting pests that go through any phase of the life cycle.
The latter, universal remedies, are more chemically active and have a stronger effect on both beetles and plants (and if people do not comply with safety standards, they also affect people). Naturally, not all, but many of the tools in this group are phytotoxic, that is, they negatively affect the growth of potatoes and the ripening of their tubers.
Potatoes before planting
If there is such an unpleasant opportunity, it is recommended not to handle in any way with such means potatoes intended for planting next year. At best, after such a treatment, it will give very weak shoots and offspring, at worst, it will not rise at all.
By methods of exposure
In turn, according to the methods of use, funds against the Colorado potato beetle are divided into the following groups:
- picklescreated for the "dressing" of tubers (by this term is meant a special preplant treatment of tubers),
- spray productsApply to spray leaves or stems with sprayers.
The main classification currently used divides these agents according to their methods of exposure to pests.
- Contact means. The defeat of pest beetles occurs when insects come in contact with the treated stems, leaves, or flowers of the bush attacked by them. Such means have one major drawback: during rains, irrigations or any other ways of contact with water on the plant, they are washed away. The latter implies spraying such products in dry weather, when no rain is expected, and no irrigation is planned.
- Intestinal means. These substances get into the body of beetles through their food.
- System tools. This category of funds gets inside the plant, filling it almost entirely. As a result of such exposure, the leaves and stems of the plants become poisonous to beetles.
By active substance
The main active substances against Colorado beetles are:
- Avermectins. They are the product of vital activity of streptomycetam fungi. Can also be obtained by industrial means. The most common part of the insecticide against the beetle is a modification such as avertin-H or aversectin-C. The first works well on larvae and adults, the second - on all forms of the beetle, including eggs and pupae. However, it should be remembered that both intestinal and contact preparations based on avermectins are not very dangerous for humans, however, they can be poisonous for other insects, for example, bees. Therefore, the use of such drugs in the vicinity of apiaries is recommended with caution.
- Pyrethrins. These are substances that are contained in the cells of the plants of the Aster family. Can also be synthesized artificially. Funds based on them block the nervous system of beetles, causing their death. Also, like the previous group, they are of low toxicity to humans, but poisonous for fish and bees. In addition, at high temperatures (above + 25 ° C), their action diminishes significantly, until it is completely absent.
- Phosphorus compounds. Means against insects belonging to the third class of danger. With prolonged low concentration effects in beetles in general, immunity can be developed for preparations of this group.
- Neonicotinoids. These substances are used to create systemic agents against the Colorado beetles.
How to use insecticides
The low toxicity of any insect repellent does not mean that it can be used without fear for your health. This means that the purchase and use of such drugs requires compliance with certain precautions.
- you need to buy only certified products that meet the standards
- It is forbidden to use insect repellents with expired shelf life.
- inaccessibility during storage for children or pets
- the storage conditions of the preparations must comply with their instructions, as a rule, this is a dry, dark and cool place
- the poison is dissolved in water (or other solvents) exactly according to the instructions and at the doses indicated there, an overdose of the drug can be very dangerous for both people and the environment
- each drug is compatible (or incompatible) with any other drugs, this information must be indicated in the instructions, the use of incompatible drugs in the same place at the same time is prohibited
- spray solutions should be prepared exclusively prior to their use (at the earliest - two hours before spraying)
- it is best to sprinkle potatoes in the morning or evening in dry weather
- the sprayer should wear special clothing — a suit that protects the skin from the possibility of the preparation getting on them; the use of protective equipment such as goggles, a respirator and gloves is mandatory
- It is forbidden to eat, drink, smoke or talk during spraying
- if the insecticide has come into contact with the skin, it is recommended to wash it off with plenty of running water
- the remains of the solution can not be drained into the sewer, they must be poured into a dug hole in the ground somewhere on the waste ground, then this hole must be buried
- at the end of the spraying, it is necessary to wash the sprayer, wash the working clothes thoroughly, and the worker himself to take a shower after washing with soap
- each insecticide is valid for a certain time, re-processing before this period is not allowed, the time specified in the instructions.
Preparations used for dressing
Means of this type are able to protect young potatoes only for a certain time. After this time comes to an end, the chemical decomposition of the insecticide occurs. To beetles at the end of this period could not damage the plants, it is necessary to process the site again, but using some other means.
It is a drug of the system principle of work. Manufacturer - German chemical concern "Bayer". The preparation contains the following active substances:
- imidiacloprid, an insect repellent developed over ten years ago and having an excellent characteristic: the protection of tubers treated by it retains its effectiveness for one and a half months, in addition to the Colorado potato beetle, the tubers will be protected from cicadas, aphids, ticks, and soil parasites ( wireworms and scoops) will bypass the plot,
- penzicuron, a remedy against fungal infections, the time of protection of potatoes from various forms of fungus is about 40 days, in the first place these diseases include blight and rhizoctorosis,
The tool belongs to the third class of danger. The working concentration for applying this agent is 1 to 20. The consumption rates are as follows: 1 kg of potato consumed 1 ml of the drug. Pre-planting is carried out: the tubers are stacked in one layer on a tarpaulin or soil and they are sprayed with a solution prepared earlier. The solution has a pink color, so the rhinestone can see how well the tubers will be covered with it. When the solution dries, a thin film layer forms on the tubers.
After the mortar has dried, the tubers should be turned over to spray their lower part. Then they should be dried again, and then proceed to planting. This is required: to plant in order to dry both sides of the potato, otherwise the effectiveness of the agent will noticeably decrease. It is also recommended to process the potatoes near the landing site, so that during transport it does not tear off the insecticide film from the body of the tuber.
Since the remedy enters the stem and leaves of the plant, the beetles, starting to feed on them, immediately die, without even having time to lay eggs. In the tubers, which are formed on the bush again, and which then will be removed as a crop, the tool does not penetrate. An additional function of the drug is the stimulation of the growth of potato bush and anti-stress effect, since the specimens treated by it are much easier to tolerate a decrease in temperature and lack of water. When it expires, the tool is completely decomposed into non-hazardous components.
Also a systemic means against insects, which is based on the same drug, imidiacloprid. Similar to the previous preparation, it produces a complex plant protection not only against the Colorado potato beetle, but also against wireworm and against other parasites. Taboo can be used together with fungicides.
The solution is made as follows: in a liter of water must be dissolved 8 ml of funds. This will be quite enough for dressing about a centner of potato tubers. The composition of this drug includes sticky surfactants that can create a thin and durable film on its surface that holds the insecticide around the tuber. The film is strong enough to allow the tubers to be pickled far from the point of disembarkation; during transportation, the protection from the tubers will not crumble.
For better visibility of the pickled layer, it has a pink color. Since the germination of sprouts is possible when turning over the sprouted potatoes, Taboo can be used to process the tubers directly in the planting holes. On spraying 100 square meters. m square must be diluted in 10 liters of water 4 ml of the drug. At the same time, the solution must be made homogeneous; this can be achieved as follows: At the beginning, the tool is dissolved in a glass of warm water, and then the resulting glass of highly concentrated product is poured into a 10 liter container.
The tubers are placed in the holes, and then they are sprayed with an average consumption of about 30 ml of funds for one tuber. Poison permeates the shoots and leaves of the plant, but does not fall into the tubers. The validity of the drug is 1.5 months, which, given the life cycle of the Colorado potato beetle, does not allow the latter to have time to lay eggs.
Spraying products for bushes
The product is packaged in 1 and 5 ml ampoules or in 10 ml vials. Consumption per 100 square meters. m is 1 ml per 10 liters of water. The duration of the funds - about 30 days. This insecticide is allowed to process potatoes only once per season.

TOP-5 funds from the Colorado potato beetle. Description of pest activity, classification of funds against it (Photo & Video) + Reviews
Protection of potato crops from pests in the form of the Colorado potato beetle and its larvae is carried out throughout the year. If the site is small in size, even very simple methods may be suitable, consisting in the banal manual gathering of insects, however, larger spaces where even semi-industrial cultivation of potatoes is conducted require the use of specialized tools. Therefore, it is always necessary to have on hand the whole complex of necessary preparations and technical means for working with them in order to be ready to meet the enemy.
This tool - an effective way to cope with the Colorado potato beetle. The drug is sold in ampoules of one milliliter: there is enough volume for a bucket of water. The resulting prepared solution is enough to spray 100 m2 of fields. Note that the drug has a systemic effect, penetrates deep into the plant tissue, and affects insects by penetrating into their digestive organs.
The drug is not washed off by rain, which increases the duration of exposure. The maximum period during which the tool will kill insects - 4 weeks. In addition to adult individuals, Konfidor also affects the larvae of the Colorado potato beetle.
Insecticide system-contact effects. Основное поражающее вещество — фипронил. Воздействует препарат путем поражения нервной системы насекомых, приводя их тем самым к гибели.
Форма выпуска — ампулы по 1 мл: этого объема достаточно для 10-литрового ведра воды. Перейдя по ссылке можно больше узнать про препарат Регент от колорадского жука.
Also a systemic insecticide, the impact in this case occurs due to the composition of imadacloprid. The tool is of Russian origin, and is also very popular among our gardeners. Packaging - 1 ml and 10 ml. In addition to the Colorado potato beetle, the Commander is effective against flies, aphids, wireworms, butterflies.
The tool penetrates into the foliage, and then gets into the roots: thus the poison appears in all tissues of the plant. The pest dies very quickly after eating the poisoned leaf. If the concentration of the solution in this area is high, then the Colorado potato beetle dies already in contact with the substance. We note the high destructive ability of Commander: he kills both adult beetles and their larvae. Clicking on the link you can learn more about the tool from the Colorado potato beetle Commander.
The poison from the Colorado potato beetle The killer is an effective combination drug, effective in combating not only the Colorado potato beetle, but also other types of pests. The drug is available in 1.3 ml ampoules. The effect of the remedy is based on the suppression of the nervous system of pests, as a result of which the latter perish.
For the complete destruction of the Colorado potato beetle in this case, just a day is enough. And within 16-21 days after treatment, the Killer retains its damaging effect.
Poison from the Colorado potato beetle. The executioner is a combined insecticide of a new generation, effectively striking the Colorado potato beetle. The product is available in 2 ml ampoules: one pack contains five such ampoules. The tool is effective at all stages of pest development: from the egg to the adult. The executioner acts by damaging the insect's nervous system, and also blocks its respiratory tract.
The manufacturer guarantees a 30-day continuous period of protection against the pest after spraying this drug. We note the high toxicity of this agent for bees.
This is an inexpensive domestic remedy against the Colorado potato beetle, as well as other pests of fields and gardens. Means is issued in the form of suspension with a volume of 3 ml. As part of the means substances that affect the nervous system of insects. The death of pests is fixed on the second or third day after treatment with the Napole.
We note the effectiveness of the drug: it equally successfully destroys both adult beetles and individuals at the larva stage. For three to four weeks after treatment, the tool retains its damaging effect, and weather conditions are not a hindrance to it.
The poison from the Colorado potato beetle Sonnet this remedy contains hexaflumuron in the poison, thanks to which it exerts its deadly effect on pests. Consumption is extremely economical: one ampoule in 2 ml per bucket of water is enough to spray 100 m2 of a potato field.
Note that the drug in the usual sense of insects does not poison, but only blocks the development of chitinous cover in the larvae, because of which the latter can not transform into adult insects. As you understand, on those individuals that have already reached an adult state, the Sonnet will not work.
However, adult females also eat the leaves treated with Sonnet, after which their offspring become unviable. Thus, without destroying the beetles directly, Sonnet still leads to the death of the colony.
The drug is not afraid of rain and watering, retains its impact for forty days. In addition, according to the manufacturer, insects do not develop habituation to the drug, that is, the Sonnet can be used continuously.
This tool is capable of striking not only the Colorado beetles, but also practically the rest of the set of pests. The preparation is produced in the form of an aqueous emulsion, as well as in the form of a powder. To prepare a working solution with a volume of 5 liters, it is necessary to dissolve 5 ml of Karbofos.
Note that the tool is not a system, therefore it is washed off in the rain. Based on this, treatment with Karbofos should be carried out only in dry weather, and having made sure in advance that rain is not expected in the next few days. And here is how the processing of strawberries karbofosom spring, will help to understand this information.
If less than 20 days are left before harvesting, the drug should not be used. Note the high damaging ability of karbofos against bees.
Each new generation of insecticides is becoming more secure, effective and has an increasingly pronounced lethal effect. That is, the quality of funds is constantly growing: therefore, the current agrarians have a decent choice of, indeed, good means to fight the Colorado beetle.
No less popular is the insecticide Aktar from the Colorado potato beetle. But before use, it is necessary to familiarize with the instructions for use of Aktar.
Science does not stand still, and insecticides of a new generation are replacing poisonous chemicals - the so-called biological preparations. The great advantage of these products is that they are harmless to plants, insects, birds and animals. In addition, substances do not accumulate in the fruits of useful plants.
The impact is due to special bacteria, of which, in fact, biologics and consist. These bacteria of a particular species infect the larvae and adults of the Colorado potato beetle, resulting in the death of the colony. Note that, on average, the effectiveness of these drugs is slightly lower than the chemical ones, and the process of the death of insects is stretched in time. However, the safety of bioinsecticides for someone can cover all their possible disadvantages. Let's get acquainted with the most effective means of this category.
This tool is widely used in their work by those farmers who adhere to organic potato cultivation technologies. The tool does not accumulate in the roots, and therefore, processing can be carried out not only before flowering, but throughout the growing season.
The impact occurs as follows: after spraying the drug penetrates the leaves, then these leaves are eaten by beetles and larvae. After the insect ate the poisoned leaf, it develops toxicosis, and in 3-4 days death occurs. On average, in five days, the death of the entire colony is already stated.
By cons Bitoxibacillin can be attributed to its low efficiency at temperatures below +18 degrees. In addition, the impact of the funds briefly - only 6-7 days after the procedure.
In addition to Bitoxibacillin, the following drugs are also considered effective against the Colorado potato beetle:
In order to initially protect potatoes from the Colorado potato beetle, gardeners recommend treating tubers and beds with special seed dressings. Having got on such a cultivated field, the insects will not even lay the larvae on it - so much terrain will be uncomfortable for them.
Minus pre-treatment - it only lasts until the time when the plants begin to bloom. However, this is already good, since by that time the sprouts become strong and strong, and due to coarsening they are not so tasty for the beetle.
The following preparations are recommended as disinfectants:
- Taboo. Following the link you can learn more about how to use Taboos from the Colorado potato beetle and wireworm.
It is quite simple to apply such means: you only need to prepare the solution according to the instructions, and then spray them with tubers before planting in the wells. Sometimes it is also sprayed into the wells directly.
Some useful recommendations for the use of insecticidal drugs against the Colorado potato beetle.
It is best not to wait until the Colorado potato beetle captures your potato field, but to carry out preventive preventive spraying of the area before planting. Use for this purpose special preparations acting on pests and their larvae through the soil or directly (but not through the digestive tract).
Process also potato tubers before planting. This measure will prevent the emergence of the larvae of the Colorado potato beetle.
As soon as potato sprouts appear, it is recommended to immediately treat them with insecticide in low concentration. The Colorado potato beetle has a weakness specifically for young shoots, so preventive spraying can stop the spread of the pest. It will also be useful to learn about how to spray cabbage from aphids.
To carry out the processing of potatoes from the Colorado potato beetle can be when the tops are growing, before flowering occurs. If you poison the plants with chemicals during and after their flowering, it may adversely affect the future harvest.
On the video - preparations from the Colorado potato beetle on potatoes:
Insecticides should not be sprayed near water bodies, since most of these drugs have a detrimental effect on fish. Next to the apiary, it is also undesirable to use them: with active spraying, the bees may die, and then neither honey nor a good crop of plants requiring pollination by insects can be seen. And here is how the fight with wood lice occurs in the garden, and what chemicals should be used is indicated here.
As you can see, there are enough funds today against the Colorado potato beetle. Choose a drug based on your needs and taking into account all sorts of environmental protection measures. Be sure to follow the instructions when preparing the working solution, and do not forget about preventive measures to minimize the use of chemistry in the garden.
