The best remedies and preparations for the Colorado potato beetle and its larvae

The Colorado potato beetle is a dangerous pest. The insect can destroy the planting of potatoes and other nightshade crops in a short time. The fight against him must begin in early spring, when the garden is planted. They recommend starting to fight in the fall. This will help reduce the number of adults capable of breeding.

Features of the Colorado potato beetle

Fighting the Colorado potato beetle is difficult for many reasons.

1. In autumn, adult females dig deep into the ground, and in spring they begin to lay larvae.
2. The first larvae appear on the back of the leaf, so they are difficult to notice.
3. He likes to enjoy not only potatoes, but also petunia, eggplant and other nightshade.
4. During the day, the female is able to lay up to 80 eggs, and during the season 800-1000.
5. Larvae and beetles themselves have a great appetite. One larva eats up to 1 gram, and a bug - up to 4.
6. Adults are able to hibernate up to 3 years even in a state of hunger.
7. The insect quickly gets used to insecticides, so the funds should be constantly changed.

There are few natural annihilators in nature for the beetle. Birds and other insects are not able to cope with pest colonies, as the Colorado potato beetle multiplies rapidly.

The insect life cycle consists of stages. First, the female lays eggs. They have a bright yellow or orange color. After 10-14 days, red-brown imago larvae appear. After another 20 days, their color changes. The adults become orange. After that, they dig into the ground to pupate. For one season, the insect gives 4 generations of Colorado beetles, a photo of each of the stages of development will help to accurately determine the presence of a pest.

How to get rid of the Colorado potato beetle

The control of striped pest is a laborious process, including the use of various methods and techniques (prevention, biological, chemical preparations, alternative methods). It is most effective to use several options at once.

Preventive measures help to reduce the number of pests on the site.

1. During cultivation, all agricultural work is carried out correctly and in a timely manner. At the same place, the plants that feed on the striped pest are planted with an interval of 5 years.
2. In the garden adhere to the rules of crop rotation. The cultures are arranged in such a way that garlic, beans, and beans grow next to potatoes and solanaceous.
3. Plants of the same genus (potatoes, eggplant, tomatoes) cannot be placed at one place several times in a row.
4. After harvesting, the plot is cultivated from nightshade weeds. After the emergence of their shoots, mineral and organic fertilizers are applied, they dig the soil 20 cm.
5. The beds should be clean throughout the entire growth period. Weeds are removed with roots.
6. During hilling, the lower leaves are covered with earth.
7. Regular weeding and loosening of the earth between rows reduces the number of insects.
8. In the fall, before digging on the surface of the site, you can distribute the husks of onions or garlic.

Of course, such measures will not help to completely get rid of the pest, but to reduce its number is real.

Environment-friendly destruction methods

There are many ways to control pests. Many prefer methods in which there are no chemical components. They do not always help to completely get rid of, but will reduce the amount of the pest.

1. Using mulch. After emergence in the aisles, mowed grass is distributed. She will not allow insects to multiply. As mulch use bark, hay, straw, large sawdust.
2. Bedbug perillus. The natural enemy of the Colorado potato beetle. If he appears on the site along with striped harm, the landings will be saved without the use of chemicals.
3. Traps for the pest. Simple in design containers with filling are placed around the perimeter of the site. Periodically, the beetles are destroyed, and the filling is refreshed.
4. Infusions of herbs for spraying. Plant-based solutions (wormwood, calendula, mustard) can be used as a means of control.

Effectively use such methods in small suburban areas. And with large areas without chemical insecticides can not do.

Chemicals

Chemical processing of potatoes can be done at the stage of preparation of seed material. There are a number of drugs that are used for such purposes. They help protect potatoes from the Colorado potato beetle before emergence. Another group of drugs is used to spray the ground part of the plant during the growth period. Among all insecticides, proven effective drugs can be distinguished.

Aktara

An effective drug from the Colorado potato beetle, which is chosen by vegetable growers. Has an intestinal contact effect. After processing the plantings, the active components penetrate all the terrestrial parts of the plant in 1-3 days. During eating, toxic substances enter the stomach, poisoning the body.

Poison the Colorado potato beetle on potatoes in any weather. The commander is not addictive in insects, is not dangerous for humans, animals and plants. Processing at any stage of the development of potato plantings is allowed.

The potatoes are spread on a tarpaulin, sprayed, then the tubers are turned over and the processing is performed on the other side.

Since the agent penetrates the stem and leaves during plant growth, insects eat it along with the green mass and die. They do not have time to put off the larvae. Belongs to the third class of danger.

Additionally, treatment with the Prestige drug stimulates the growth of culture, enhances anti-stress endurance. After the expiration date, the product decomposes into components that are not harmful to the environment and humans.

Biological preparations

Widespread use in gardeners have found biological insecticides, which are less safe. After processing, you can harvest in 7-10 days, as it does not accumulate in the tissues of plants.

The disadvantage of biological agents is that they destroy larvae of various ages and adult insects, but they do not act on laid eggs. Therefore, treatments are performed up to 3 times per season.

Among biological insecticides in the fight against Colorado potato beetle, you can use:

• Bitoxibacillin;
• Fitoverm;
• Nemabact;
• Acarin;
• Anthony-F.

Tatyana, Smolensk

I can not use chemical potent drugs, as young children are constantly around the beds. At first I tried to collect, but it was simply impossible to destroy everyone, so I began to fight on a potato with a Colorado potato beetle using biological insecticides.

Vladimir, Volgograd

For a long time I do not think how to process potatoes from the Colorado potato beetle. Immediately starting to use chemicals. I never process the tops twice with the same tool. Change regularly. The first time I process seed material.

Svetlana, Minsk

Every year I fight. The site is small, so first they begin to collect with their hands. I do not buy chemistry, I use poison from the Colorado potato beetle of my own preparation. I alternate folk ways. I alternate infusion of wormwood and birch tar.

Protection of plantings of potatoes and other nightshade crops from pests should be carried out throughout the year. If you want to protect a small area, you can use simple methods, for example, manual collection and removal of leaves with larvae of the Colorado potato beetle. For large areas, it is better to use insecticides. It is difficult to choose the most effective remedy from the Colorado potato beetle, since the pest gets used to the preparations, which requires the constant creation of new methods of control.
