Using bioproducts for soybean protection against the soybean pod borer (Leguminivora glycinivorella Mats.) under the conditions of the steppe zone of Primorsky kray

Abstract

This paper presents the results of a study on bioproducts BioKill, EC, and Proclaim, WG, against the soybean pod borer (Leguminivora glycinivorella Mats.), which damages soybean pods in the agroecosystems of Primorsky kray. This species is one of the main soybean pests in the Russian Far Eastern federal district. The research was conducted on late soybean variety Briz in the conditions of the steppe zone of Primorsky kray – in the soybeans fields of FSBSI “FSC of Agricultural Biotechnology of the Far East named after A.K. Chaiki”. The plan of the experiment included the use of bioinsecticides BioKill, EC, and Proclaim, WG, for treating plants either during the growing period (two times) or in combination with seed-applied insecticide Imidor Pro, SC. Our research goal was to evaluate the biological and economic efficacy of the bioproducts against Leguminivora glycinivorella Mats. It was established that applying the bioinsecticides decreased the degree of the damage caused by the soybean pod borer (larvae) to soybean pods and seeds and positively affected the productivity of soybean plants. Bioproduct BioKill, EC, had the highest biological efficacy. The protective properties of bioinsecticide Proclaim, WG, were observed to be weaker. The research results demonstrated that bioproducts BioKill, EC, and Proclaim, WG, were effective against the soybean pod borer Leguminivora glycinivorella Mats. and could be used as soybean protection products in the agroecosystems of the Russian Far East.
