In the backyard and summer cottages, the crop is damaged by the larvae of beetles (eastern and western May beetle) and caterpillars of several types of scoops (southern gnawing, exclamation, ipsilon scoop, dirty brown earthen scoop, C-black, clover, tomato, etc.). These pests feel comfortable in different climatic zones and in some years they cause significant harm to vegetables, fruits and berries, fodder and other agricultural crops.
On strawberry plantations, in gardens and nurseries on young trees, the larvae of beetles, mainly May ones, harm: adult beetles - the leaves of plants, and their larvae (popular names - khrobaki, furrows, etc.) - to the roots. It is difficult to fight them, since they live in the ground. They winter there, and in the spring, by the beginning of the blooming of leaves, trees and bushes are populated. The duration of generation is 3-4 years in the southern and southwestern regions, and in the north - 5 years (eastern beetle). The larvae prefer loose, well-warmed soils. Beetles lay their eggs in the soil. The larvae feed on humus and small roots. In the so-called "flying years", the beetles are especially numerous.
Adult beetles are destroyed with the help of ground treatments with insecticides (groups of pyrethroids, organophosphorus drugs, neonicatinoids) - zolone, fufanon, danadim, decis, karate, fury, confidor, etc. Grizzly preparations (granules) in the soil give excellent results against larvae - 5 g / sq. m, Medvedtoks-U - 300 g / weaving. Granules are applied in the spring at the beginning of the growing season of plants to a depth of 5-10 cm (if the soil is dry, it must be watered), and on beds with strawberries - in the aisles at a distance of about 5-10 cm from the plants.
Many scoop caterpillars damage some parts of plants: inflorescences, ovary, leaves, stems and fruits. The main way to combat them is spraying with one of the insecticides: in the spring - decis, karate, fury, and in the summer, organophosphate preparations should be used: zolon, dursban, fufanon, danadim.
You should buy drugs only in specialized stores. The consumption rate depends on the form of drug release (granules, powder, emulsion concentrate). It is indicated on the package.
Sprayed in the evening, finish processing 30 days before harvest.
