Description of the Colorado potato beetle
The Colorado potato beetle is one of the most dangerous pests in the garden. This is a representative of the leaf beetle family, imported from Colorado and spread throughout Eurasia. In Russia, the Colorado potato beetle appeared in the forties of the twentieth century.
The pest is easy to recognize by its characteristic black and yellow color. The size of the beetle is no more than 12 mm. The body of the insect is oval, with stripes on the back and black spots on the head. Beetle larvae are gray or black and yellow.
The Colorado potato beetle spends winter at a depth of 0.3 m. If the soil is sandy, then the pest penetrates to a depth of 0.5 m. Then its population does not die during frosts. Depending on the ambient temperature and rainfall, the Colorado potato beetle comes to the surface in May or a few weeks earlier.
Due to the developed wings, the Colorado potato beetle can make long flights. Usually the pest appears from neighboring areas or as a result of mass migration.
Harm from the Colorado potato beetle
The female Colorado potato beetle lays eggs on the lower part of plant leaves from early spring to autumn. In one summer, 2-3 generations of beetles can appear.
The larvae begin to hatch within 5-14 days, which largely depends on the temperature. The larvae go through several stages of development. During this period, they need intensive nutrition, so they intensively eat the upper parts of the shoots.
Then the larvae go into the ground, where pupation and the formation of an adult take place. The Colorado potato beetle feeds on plants for a period of up to 20 days. In hot weather, insects fly in search of a food source. As a result, the area of their settlement is several tens of kilometers.
The pest can be found on eggplants, peppers, tomatoes. The insect is active from April until the end of the summer season. If the leaves of the potato are not sufficiently formed, then the beetle moves to other crops.
In spring, the Colorado potato beetle eats young shoots, in the middle of summer it moves to inflorescences. At the end of the season, the lower parts of the potato suffer.

Active ingredients
The composition of the Killer preparation includes the following substances:
- cypermethrin in an amount of 50 g per liter;
- chlorpyrifos at a dosage of 500 g per liter.
Cypermethrin is a chemical made up of 8 isomers. Each of them has a specific effect on insects. The combination of these ingredients has a detrimental effect on the Colorado potato beetle.
The substance affects the nervous system of pests due to contact and intestinal effects. As a result, the life of the Colorado potato beetle stops, and the insect dies.
Its effectiveness remains high for another month. The substance retains its properties under the influence of the sun and high temperatures.
Chlorpyrifos is harmful to Colorado potato beetle larvae... When an insect enters the body, the substance paralyzes it and becomes the cause of death. Chlorpyrifos affects the Colorado potato beetle through the respiratory system.
Chlorpyrifos is resistant to environmental factors. The activity of this component can last for 70 days. The substance remains in the soil for up to 4 months.
Due to the complex effect of active substances, the effect is exerted both on the larvae and on full-fledged individuals. Therefore, the drug is fast acting and retains its properties for a long time under the influence of external factors.
The killer destroys the Colorado potato beetle within 2 days. The protective effect lasts for three weeks.
Time of processing
The killer is used in two ways:
- potato tubers are processed before planting;
- the bushes are sprayed during the growing season of plants.
Potato tubers are processed prior to planting. To do this, they are sprayed with a solution based on the drug. Then the tubers are mixed.

Consumption rates
When using Killer, the proportions of the substance are strictly observed. The drug is not used in its pure form; a solution is prepared on its basis.
