Protection of corn against the European corn borer when its harmfulness changes and its range expands on the territory of Belarus
Abstract
The European corn borer is a noxious corn pest in Belarus. Initially, the phytophage has developed in large number on permanent corn crops cultivated in the Southern and New agroclimatic zones, where plants damage has ranged from 30.2 to 90.0 %. Since 2015, its range has expanded, high population focuses have been formed in the central regions. The phenology of the European corn borer is presented in different agro-climatic conditions. The agrotechnical measures significantly decreasing the insect’s harmfulness have been recommended. The insecticides efficiency at depressed and massive pest development has been evaluated. An assortment of insecticides has been formed and the economic feasibility of their use in corn crops by cultivation for grain, seeds and green mass has been substantiated.
