How to get rid of the Colorado potato beetle with drugs and folk remedies

For hundreds of years, this pest has reduced the yield on fields and gardens. His name is the Colorado potato beetle. It is impossible to completely destroy this evil, but it is quite possible to considerably order its ranks.

This striped pest came to us from the American continent, so it has no natural external enemies. Over the summer, the female lays up to half a thousand eggs in small clutches of 20-25 pieces, of which orange larvae hatch, capable of completely destroying the foliage of the plant on which they sit for twenty days of her life. Statistics say that the loss of a plant by a third of the number of leaves leads to a decrease in yield by a quarter. It would seem that he has dealt with the pest on the site and one can rejoice, but the hopes for a complete deliverance from the misfortune are groundless, because beetles, flying tens of kilometers in search of food, appear again and again on potatoes. So the fight against this insect must be conducted continuously.

There are various options for pest control. Chemical - they destroy the beetle quickly and reliably, biological ones are more sparing to the environment, folk remedies combine both options

Chemicals

Pesticides Safety

Before picking up chemicals, you need to clearly understand that these drugs are poison not only for insects, but also for humans, and therefore, when using them, you need to adhere to some rules:

• Adolescents under the age of 18, pregnant and lactating women cannot be involved in work with pesticides;
• Before eating, as well as smoking, you need to change clothes and wash face and hands well with soap so that particles of poison do not enter the body;
• It is necessary to process plants with a sprayer, preferably in calm weather;
• After processing the plants, it is recommended not to weed weeds for a day or two, and after that, the weed-out plants cannot be fed to pets or poultry;
• Processing is carried out three weeks before harvesting, unless otherwise specified in the instructions;
• For guidance solutions it is strictly forbidden to use food containers.

Colorado potato beetle control chemicals

Chemicals are poison for insects and are characterized by the most rapid destruction of pests. The following are the characteristics of several drugs.

Killer

The active substance is cypermethrin and chlorpyrifos. Cypermethrin acts on adult beetles, affecting their nervous system. Chlorpyrifos is targeted at pest larvae. Both drugs act both when eaten with food, and when ingested through the respiratory system. The drug is especially effective during the first days after application, but retains its properties for a month after treatment. The drug is available in ampoules (1.3 ml.) Or in bottles (10 ml.).

Application: The drug can be used both for preventive purposes and directly for the destruction of insects.

• For prevention, take 10 ml per 0.5 liter of water. the drug.This amount of mixture is enough to process 25 kg of planting material.
• To kill insects, 1 ampoule (1.3 ml.) Is diluted in 8 liters of water. This mixture is treated with 100 square meters of land. The site is treated once a season at least 45 days before harvesting.

Destroy

Active ingredients lambda-cygalotrin and imidacloprid. The drug is available in bottles (3ml.). Both substances affect the nervous system of pests, paralyzing it. Insects enter the body through eaten leaves. The drug is valid for 20 days from the date of treatment. For processing 100 sq.m. plot dilute one bottle of the drug per 10l. water.

Kalash

The active substance is imidacloprid. The drug is available in ampoules (1 ml.) Or in bottles (10 ml.). Insects enter the body through food. The drug is valid for 14 days from the date of treatment. For processing 100 sq.m. plot diluted 1/2 ampoules of the drug in 5l. water. If necessary, repeat the treatment.

Gulliver

Active ingredients alpha-cypermethrin, lambda and thiamethoxam. The drug is available in ampoules (3ml.). Pesticides enter the body of insects through food. Each of the substances acts on the nervous system, guaranteed to disable it. Insects begin cramps, paralysis, and then death. Also, this drug serves as a stimulator of potato growth. The drug is valid for 20 days from the date of treatment. For processing 100 sq.m. plot diluted 1/2 ampoules of the drug into 5 liters. water. If necessary, repeat the treatment.

Stop beetle

Active ingredients thiamethoxam and fipronil. Complete with the tool "Stop Beetle" is the drug "IVF Potassium Humate". The insecticide enters the body of insects through food and in a contact way and acts on the digestive and nervous system of beetles and larvae. The drug is available in ampoules (3ml. + 10ml.). “IVF Potassium humate contains humates, succinic acid and trace elements in a form that is easily absorbed by plants. When processed, it increases the yield and resistance of plants to diseases.

Preparation of the solution. First bred in 3 liters. water contents of the Stop Beetle sachet, then ECO Gumat potassium is added to the composition. This amount of the mixture is treated 200-300 square meters of land.

Aktara

The active substance is thiamethoxam. The drug is available in ampoules (9 ml.), In granules (packaging 4 g) or in bottles of 250 g. Application: 1/3 of the packaging of the substance (1.3 g.) Diluted in a bucket of water. Pests cease to eat half an hour after treatment with the drug, finally insects die in a day. If necessary, the treatment is repeated after two weeks.

Corado

The active substance is imidacloprid. The drug is available in ampoules (1 ml.) And bottles of 10 ml and 25 ml. The poison enters the body of insects through food, or by contact. Destroys the nervous system, the final death of beetles and larvae occurs on the second or third day from the moment of treatment. The active substance is not washed off by rain and is valid for 30 days after treatment. For processing 100 square meters. m. 1 ml. the drug is diluted in 4 liters of water. In order for the drug to mix quickly and well, use warm water. Before pouring the solution into the sprayer, the mixture is additionally shaken. If necessary, after a month, processing can be repeated.

Regent

The active substance is fipronil. The drug is available in a set of six ampoules of 1.5 ml., Or one ampoule of 5 ml. The insecticide enters the body of pests through food, or by contact. It acts on the nervous system, causing paralysis. Finally, the pests die in a day.

For processing 100 sq.m. 1/2 small ampoule is bred in 10 liters of water. The drug is valid for 30 days after treatment. If necessary, after a month, processing can be repeated.

Lightning

The active substance is lambda-cygalotrin. The drug is available in ampoules (2 ml.) And vials (10 ml.).The difference between an insecticide is that, justifying its name, after 20-30 minutes it kills pests, paralyzing them. During the day, 100% of the pests located on the site die. Thanks to special additives, the drug is not washed off from rain and watering. For processing 100 sq.m. one ampoule is bred in 10 liters of water. Spraying is carried out no later than 20 days before harvesting.

Apache

The active substance is clothianidin. The drug is available in paper bags weighing 0.5 g, in a package of five bags. The insecticide enters the body of insects through food and in a contact way, in addition, after an hour after spraying, it penetrates the tissues of the plant and protects even young shoots that appear after treatment from the inside.

It acts on the nervous system of pests, killing them. The drug protects plants for a month from the day of treatment. For processing 200 sq.m. one sachet, without opening the package, is thrown into one liter of water. The bag along with the contents dissolves in a few minutes.

The disadvantages of the drug:

• The solution of the drug is not intended for storage and should be used within 3 hours after guidance;
• If you spray the plants in sunny weather, while absorbing the solution into the leaves, it can collapse under the influence of direct ultraviolet radiation and lose insecticidal properties;
• Spray plants must be at least one hour before rain.

Taboo

The active substance is imidacloprid. The drug is available in 10 ml vials. The toxic chemical enters the body of insects through food. It acts on the nervous system of insects, causing paralysis.

This insecticide is intended for processing not the leaf, but the potato itself before planting. For this, 8 ml of the drug is diluted in one liter of water. About 100 kg are treated with this solution. planting material.

Before wetting the root crops, the solution is thoroughly shaken. The tubers are laid out in a row on a film coating, sprayed, then carefully turn over and process from the untreated side. An indicator of the treated surface will be staining of the root crop in red. Once the tubers have dried, they can be planted in the ground.

With this treatment, “Tabu” is absorbed into the tuber and spreads to young shoots. The Colorado potato beetle, eating young sprouts, receives a dose of poison and dies. Processing protects potatoes for 45 days.

Biological Means of Control

Biological preparations do not harm living organisms (except insects), do not accumulate harmful substances in potato tubers, do not poison the soil, water and air, after their use, potatoes are considered environmentally friendly. The disadvantages include the fact that after processing by them, the pests do not die immediately, but after some time, as well as the instability of the drugs, and, as a result, the increase in the number of treatments on the site.

Bitoxibacillin

The active substance is the microbial culture of Bacillus thuringiensis. The drug is available in bags weighing 20 g. After spraying into the intestines of larvae and Colorado potato beetles, bacteria invade that destroy the digestive system of the pests. The maximum effect appears on the seventh day after treatment. Bitoxibacillin plants are sprayed at a temperature not lower than 18-20 degrees Celsius. For processing 100 square meters. m. 80 g of powder is diluted in 10 liters of water. The drug does not affect the eggs of the Colorado potato beetle, so after 7-10 days, the treatment is repeated up to 4 times per season.

Agravertine

The active substance is Agravertin. The drug is available in ampoules of 5 and 10 ml .. The drug enters the body of insects through food. It acts on the nervous system of pests, killing them.The nutrition of insects ceases within 6 hours after treatment, they die in bulk on 2-3 days, the maximum effectiveness of the drug occurs on 5-6 days. The higher the ambient temperature, the more effective Agravertin acts. The drug does not affect the eggs of the Colorado potato beetle. For processing 100 sq.m. 3 ampoules (15 ml.) Are diluted in one bucket of water. The induced solution must be used within two hours after preparation. The drug is valid for 20 days after treatment. If necessary, after a month, processing can be repeated. Spraying is carried out no later than 20 days before harvesting.

Nemabact

The name of the drug is made up of the words Nematode and Bacterium. When using this tool, the larvae of the Colorado potato beetle destroys a specially bred nematode microscopic worm. The nematode enters the body of the larva, eats the pest from the inside, multiplies rapidly and looks for the next victim. The nematodes brought to the site actively clean it for two to three years; for the winter, they go into the ground and hibernate, so that in the spring, having intensified, they will again begin to clean the site of the larvae of the Colorado potato beetle. Nematodes are grown in a biological laboratory, applied to foam rubber and packaged in bags. Store the drug in a refrigerator at a temperature of two to eight degrees Celsius.

Transportation is carried out in a cooler bag. Bringing Nembact to the site, you need to put it in the shade for an hour and a half to acclimatize the worms. Then warm water is poured into the bucket, the bucket is covered with a mosquito net on top, onto which foam rubber is shaken from the bag. In an hour and a half, the worms will pass from the foam into the water and settle on the bottom. Shake the water, pour a half-liter jar of suspension on the watering can, and evenly distribute the contents of the watering can to five square meters of the site. Thus, one Nembakt package is distributed per one hundredth of the garden.

After treatment with Nembactom, the garden must be watered to wash off the worms from the leaves of potato tops. The remaining foam rubber is dug at the edge of the garden so that worms that do not fall into the water crawled out of it into the soil. Nembact is introduced in the evening in cloudy weather at temperatures up to 26 degrees Celsius. If the soil on the plot is dense, then before using the drug it needs to be loosened a little.

Colorado forte

The active substance is neonicotinoid imidacloprid. The drug is available in ampoules of 2 ml., 5 ampoules are sold in the kit. . The drug enters the body of insects through food and by contact. It acts on the nervous system of pests and causes paralysis. Pests are massively killed within 3-5 days after spraying. For processing 100 square meters. m. one ampoule is bred in 10 liters of water. The drug is valid for 30 days after treatment. Spraying is carried out not later than 20 days before harvesting.

Folk pest control

Many gardeners refuse to buy means of combating the Colorado potato beetle, believing that folk remedies cope with pests no worse. There are many options for folk remedies and recipes: these are tinctures and decoctions; dry pollination with various substances; the use of volatile; the use of traps against bugs, the use of agricultural technology.

Without a doubt, the most common way to deal with a pest is manual collection. Beetles and larvae are collected in a jar with strong saline solution at the bottom. If the planting area is small and it is possible to regularly inspect the plants, then this method is unrivaled.

"Dry" pest control methods

When using "dry" methods of pest control, potato tops in the morning, until the dew has subsided, or immediately after the rain, while the leaves are still raw, dusted with dry substances.

Wood ash is well suited for pollination. Sifted ash dusted plants at the rate of 10 kg. per hundred square meters. Before flowering potatoes, pollination is carried out once every two weeks, after flowering - once a month. Also sprinkled with aisle aisle.Larvae and adult bugs die within 1-2 days after treatment. There are recommendations that instead of ash, cement or gypsum is used.

In order for the Colorado potato beetle to bypass the plantation, sprinkle fresh sawdust of conifers between the potato rows. The beetle is very sensitive to the smell of fresh wood. Before flowering potatoes, aisles are sprinkled once every two weeks, after flowering once a month.

Read the same way how to deal with late blight on potatoes.

Trap use

In the spring, while the number of overwintered beetles is minimal, traps are used to catch it.

• At the site they dig in banks so that their edge is at ground level. The top of the jar is smeared with potato juice, and finely chopped pieces of potato are placed inside. From time to time, checking the cans, they are shaken out of the bugs that have flown in on a delicious smell. One jar is dripped onto 5 sq.m. plot.
• Sliced ​​potato wedges are soaked in a urea solution (100 g. Per 1 liter of water) for two days. In the evening, poisoned baits are laid out in open banks in the area at the rate of 3-4 pieces per 5 sq.m.

Use of volatile

The Colorado potato beetle is looking for edible plants focusing on smell. Many summer residents plant plants along the perimeter of the site with potatoes, the smell of which is unpleasant for the Colorado potato beetle, so that as many insects as possible spread around the plantings. The following plants are suitable for this: marigolds, calendula, borago, nasturtium, coriander, tansy, catnip, white nettle. And if you fence potatoes around the perimeter with plantings of beans, onions, garlic or horseradish, then in addition to phyto-protection, they also get an additional crop.

It is also possible to simultaneously plant potatoes and a bean seed in one well, which, growing, protects the potato bush with its aroma. Beans as they ripen are removed from the garden.

The use of agricultural technology

The harm from the Colorado potato beetle is reduced if varieties resistant to pest damage are used as planting material: Bryansky reliable, Zarevo, Kamensky, Lasunok, Nikulinsky, Temp, Morning Morning. These varieties possess dense, hairy leaves with an unpleasant taste and are therefore not attractive to beetles as food.

In order to reduce the number of bugs remaining to winter on the site, two weeks before harvesting, they cut and destroy potato tops, thereby causing the beetle to starve in the fall.

Late autumn digging of a site with a depth of 25-30 cm with the addition of onion and garlic husks contributes to the death of beetles that have gone wintering in the ground.

On a note: Chickens of the Faverol breed and turkeys can be taught from childhood to feed on the larvae of the Colorado potato beetle, and then released into the garden to collect pests.

Destruction of pests with tinctures and decoctions

Recommendations when using tinctures and decoctions

• Spraying is done in calm weather on a dry leaf surface.
• Sunlight destroys the insecticidal properties of decoctions, so it is better to spray in the evening.
• So that the broth sticks better and keeps on the leaves, soap is added to it during cooking.
• Ready-made solutions quickly lose their properties, and therefore they are used within a few hours after preparation.
• Solutions prepared according to popular recipes must be alternated, since insects quickly get used to the same irritant.
• Treatment with herbal decoctions is carried out every 7-10 days.
• Before eating, as well as smoking, you need to change clothes and wash your face and hands well with soap so that particles of infusion do not enter the body

Tatyana, 60 years old

I live in a village. I have been growing potatoes all my life, we eat them ourselves, and a lot is needed for piglets. Every year, every two weeks, the husband put a sprayer on his shoulders and walked and sprayed pesticides all day. Then he coughed from poison in his nose. Two years ago, the son-in-law brought Nembact. They scolded him for a long time - an expensive drug. Diluted the drug, poured into the garden - look, and after a week not a single larva. And do not spray, do not poison yourself! We’ve been resting for two summers, and cute worms are working for us! Many thanks to the scientists for bringing such a wonderful drug.

 

Alexander, 35 years old

Five years ago, they bought a house in a village near a river. My wife started a small garden. As usual, we come, my wife to the garden, and I to the river. To devote more time to my favorite fishing trip, I bought Lightning from Colorado. It really all came out at lightning speed - I scooped up water, parted the ampoule, sprayed the garden in an hour, I looked, and where I started spraying neither bugs nor larvae. He washed his hands - and into the river! It's a good thing, all the same - Lightning!

 

Sergey 55 years

I am a military pensioner, retired, bought a house in the village. The grandson is allergic to chemistry, so we don’t use pesticides at all. Everything is the old fashioned way - the potato sits with the beans, calendula blossoms around the perimeter of the plot. Once a week I brew husks, then pollinate with ash after rain, then spray with a solution of tobacco. No chemistry - one health benefit.
