Abstract

Apple plantations during the growing season are attacked by various species of insects, mites and other groups of pests that attack buds, flower buds, inflorescences, leaves, shoots, fruits, branches, stem and root. For the effective control of the codling moth, 1-2 treatments are applied for the first generation and 2-3 treatments for the second generation. At the beginning of laying, it is recommended to use chitin inhibitory preparations. When exceeding the economic damage threshold for combating apple worm caterpillars, more than 50 products with various active substances and mechanism of action are approved. Based on the above, the purpose and objectives of the research were to study the biological efficacy of the insecticide IN2020031, SC, in combating the apple pest complex. During the vegetation period of 2020, in the apple culture, favorable conditions were created for the development of codling moth and tortricidal moths. The most effective in controlling apple pests is the insecticide IN202003-1, SC, with a consumption rate of 0,5 l / ha + 1,0 l / ha (SAS), which ensures a reduction in fruit attack by apple worm codling moth 95,70 to 97,36%, tortricidal moths - from 97,17 to 94,95%.
