The Colorado potato beetle causes headaches for many gardeners who want to harvest a rich potato harvest. You have to deal with this pest constantly; it quickly gets used to chemicals. It is not surprising that manufacturers are trying to offer the most effective ways to deal with unwanted guests. The difficulty is caused by the beetle's ability to overwinter in the ground, appearing during harvest time. Moreover, he has no enemies in nature.

There are drugs of narrow and broad specialization on the market. The first act against a certain type of Colorado potato beetle. The latter have a complex effect on various parasites, affecting wireworms, aphids, etc. In the top 10 ranking, we collected drugs from both groups, considering the active substances. They were considered effective by buyers, as evidenced by multiple reviews.

Biological products

The products are considered safe for humans when used correctly. Used to spray the green part of the plant. The result is noticeable within a week. Biological drugs have a maximum effect of 14 days. Heavy rains reduce the effectiveness. Preparations are produced in the form of powder and compressed tablets. Before use, the contents of the sachet should be poured into cold water.

The active ingredients are natural insecticides; the composition does not contain a dangerous compound for humans. They enter the body of insects by contact, when sucking juices from leaves. Death occurs after a few days, as the poison accumulates in the body. The mechanism of action is identical to insecticides - they disrupt the functioning of the nervous system.

Among the effective biological products are:

• Colorado;
• Bitoxibacillin;
• Fitoverm;
• Spark bio;
• Bicol;
• Akarin;
• Actovegin.

Review

We spray potatoes in the garden with poison. We plant a separate bed of potatoes so that we can eat them young in June-July. We are treating this bed with herbal medicines. We buy different ones every time, they work the same way. The insects are not killed completely, but the number of Colorado potato beetles is reduced significantly. In large areas, using biological products is ineffective and expensive.

Biological products are sold in specialized stores, hardware departments of supermarkets, and can be ordered online. Spraying is carried out twice a month throughout the entire growing season.

How are insecticides used?

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.

Spraying potatoes

Let's look at them:

• it is necessary to purchase only drugs that have been certified and comply with standards
• It is prohibited to use insect control products that have expired
• inaccessibility during storage for children or pets
• storage conditions for drugs must comply with their instructions; it is usually a dry, dark and cool place
• dissolving the poison in water (or other solvents) is carried out exactly according to the instructions and in the doses indicated there; an overdose of the drug can be very dangerous for both people and the environment
• each drug is compatible (or not compatible) 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
• Spraying solutions should be prepared only before their use (at the earliest – two hours before spraying)
• It is best to spray potatoes in the morning or evening in dry weather
• the person spraying must be dressed in specialized clothing - a suit that protects the skin from possible contact with the drug; the use of protective equipment such as goggles, a respirator and gloves is mandatory
• during spraying it is forbidden to eat, drink, smoke; It’s also not advisable to talk
• If the insecticide gets on the skin, it is recommended to wash it off with plenty of running water.
• the remaining solution must not be poured into the sewer; they need to be poured into a dug hole in the ground somewhere in a vacant lot, then this hole needs to be buried
• At the end of spraying, it is necessary to wash the sprayer, wash work clothes thoroughly, and the worker himself should take a shower, washing himself with laundry soap
• each insecticide acts for a certain time; re-processing before this period is not allowed; the time is indicated in the instructions.

Rating of the best remedies for the Colorado potato beetle

Beetle eater

This is a new drug that is often used to kill pests on potatoes. The composition includes several active substances: alpha-cyperemthrin, which does not allow the beetle to feed and causes its rapid death, imidacloprid, which protects plants from negative environmental influences and prevents even an adult parasite from harming them, and clothianidin, which provides the crop with long-term protection. The beetle eater destroys even those beetles that are located on the lower sides of the foliage.

It is enough to carry out the treatment only once during the growing season. In this case, the potatoes will be protected for the whole season. Before use, please read the instructions:

1. Dilute the concentrated drug in a liter of water.
2. Add more water to this mixture. As a result, there should be 1.5 ml of concentrate per 3 liters of water. The product should be used immediately and should not be stored.
3. Spray the stems and leaves with the preparation. Manipulations are best done before 10 am or after 18 pm. Consumption is 3 liters per 100 square meters.
4. After processing, at least 3 weeks must pass before harvesting.

It is important that there are no children or pets nearby during the procedure; in addition, it is necessary to protect the skin with protective clothing. Rubber boots, a respirator and rubber gloves are a must. It is advisable not to combine Beetleworm with other similar products.

Price – 26 rubles per 1.5 ml ampoule.

Advice from experienced gardeners

The invasion of the Colorado potato beetle is a real disaster for every summer resident, so experienced gardeners have developed several effective rules, thanks to which the appearance of a pest in a summer cottage will no longer be a problem on a global scale:

1. Before planting, it is imperative to treat the planting material with special substances. This will help the seedlings take root and go through certain stages of the growing season without the negative impact of the pest.
2. Scare away the beetle with unpleasant odors. To do this, plant marigolds, nasturtium, calendula, and coriander next to the potato plantings.
3. Try to get rid of pests by attracting their natural enemies.
4. Do not neglect all agrotechnical care techniques, carry out fertilizing and preventive measures in a timely manner. The Colorado potato beetle often settles on sick, weak plants.
5. Small potato plantations can be rid of beetles using a simple mechanical method. Adults are collected by hand, and if larvae and eggs are present, the leaves are usually simply torn off.
6. When choosing means to kill an insect, the period of crop development should be taken into account. Try more gentle methods first; if they are ineffective, use strong chemicals, strictly following the instructions.

To completely remove Colorado potato beetles from your plot and obtain a healthy, high-quality potato harvest, it will be enough to follow the recommendations of knowledgeable gardeners.

A little overseas guest is capable of destroying vegetable crops in a short time. Therefore, treatment of potatoes against the Colorado potato beetle should be carried out carefully and regularly; the procedure should not be neglected. This event will allow you to harvest a rich harvest of tasty and healthy vegetables.

Classification

Types of synthetic drugs against striped pests

Chemical compositions for the destruction of Colorado potato beetles are divided into:

1. Insecticides.
2. Biological products.
3. Folk remedies.

To effectively use chemicals, you must be able to correctly correlate the choice of drug with the conditions of your summer cottage. The leading positions in the ranking of pest control products are occupied by powerful synthetic compounds with a high speed of impact: “Prestige”, “Aktara”, “Tanrek”, “Koragen”, “Respect”, “Bark beetle”.

Farmers who use natural products most often turn to urea. This nitrogen-containing fertilizer kills two birds with one stone: it feeds the plants and helps get rid of striped pests. The composition is used in spring or autumn.

Some farmers combine natural remedies with systemic microbiological preparations (Fitosporin, etc.), insecticide-acaricidal agents (Rateid, Tsifoks based on cypermethrin). In order not to harm the plantings, farmers follow the dosages of drugs recommended in the instructions.

When using insecticides and pesticides together, you need to know the degree of compatibility of the drugs.

Methods of influence

According to methods of use, synthetic drugs are conventionally divided into:

• mordants (they are used to treat tubers before planting);
• spraying agents.

Chemical compounds have different effects on beetles. Some instantly kill harmful insects, others scare off minke whales with a pungent odor, paralyze, or disrupt the functioning of the parasites’ digestive system.

Among insecticidal agents with a reputation for being effective, farmers often choose: Actellik, Punisher, Confidor, Agita, 30 Plus. The contact-intestinal remedy for Colorado beetles “Gunner Duo” also has a high rating. This insecticide destroys all harmful insects and protects the garden for a month.

Many farmers who want to get rid of the Colorado potato beetle choose the Stop Beetle insecticide. This contact-intestinal drug has a class IV hazard class for humans. Despite its toxicity, STOP Beetle is actively used by gardeners; the chemical quickly rids plants of pests without disturbing the life cycles of crops.

By composition

Colorado beetles quickly adapt to synthetic compounds. Experienced gardeners advise alternating preparations with different active substances.

Pyrethroid insecticides are less toxic than chemicals from other groups. After treating potatoes with the following preparations: “Kinmiks”, “Marshal”, “Klotiamet”, “Typhoon”, “Hurricane”, “Senpai”, you cannot dig up the tubers for at least 30 days. This protects against the effects of harmful substances that get inside the plants.

Bison

Bison is a systemic insecticide. It attacks the parasite's nervous system and prevents it from feeding, causing extinction within a few days. To treat 100 square meters, you need to dissolve 1 ml of the drug in 10 liters of water. Spraying is carried out early in the morning or in the evening so as not to cause leaf burn. It takes several hours for complete absorption, so it is best that the weather is dry.

The bison is distributed over the tops of the plant, so even the larvae, hiding in the most unexpected places, die. Judging by the reviews, the effectiveness remains at 95%.

For better fixation, the product is mixed with crushed laundry soap. You can use it a month before harvesting, but then it is no longer worth it. In the correct dosage, Bison is non-toxic.

The remains of the working solution can be used for tomatoes, cucumbers or flower crops. Treatment with this drug should not be carried out for more than three years in a row.

Taboo

This is a new generation drug used before planting. About 10 ml of product is needed for 120 tubers. To prepare the solution, you need to dissolve 8 ml of Tabu in a glass of water and shake thoroughly. Then add water, bringing the volume to a liter. Spray the tubers that are ready for planting; a dense colored film should appear on them. As soon as everything is dry, the planting material should be placed in the holes.

The manufacturer also recommends spraying furrows or holes with spread potatoes. Then the dilution rate is 4 ml per 10 liters of water. The treated areas are covered with soil from the next row.

Protection lasts about 45 days from the moment of emergence. The effectiveness of Tabu does not depend on weather conditions, in addition, in the dosage recommended by the manufacturer, it does not pose a danger to insects and animals. Additionally, the drug will protect plantings from wireworms.

It is worth remembering that the product does not protect plants from fungus, so it is recommended to combine it with Bunker or Trust, Vial. It's not worth it with others.

Treatment must take place on the day of disembarkation, since the toxicity of the poison decreases during prolonged exposure to the air or under the sun.

To prepare the solution, you need to use special containers; during work you need to use special clothing, a respirator and gloves. After the manipulations, it is advisable to take a shower. Naturally, processed tubers are prohibited for consumption.

Price – from 145 rubles per package, designed for 125 kilograms of potatoes.
