The purpose of our study was to develop biological methods to protect soybean from pests. Lepidoptera is believed to be one of the most numerous groups of insects in this crop. As a conservative estimate, 20 species of Lepidoptera were found in soybean agrocenosis; the greatest damage to Glycine max L. caused Etiella zinkinella Tr. 1832 and Helicoverpa armigera Hb. 1805. It was shown that not less than 500 m distance of crops from the main reserve of pests – robinia and the use of early ripening varieties provided the minimum loss of bean yield (no more than 0.9 – 1.9%). The use of biological preparations based on B. thuringiensis – lepidocide and bitoxybacillin allowed reducing beans and seeds damage by pests by 20-30%. |
