Abstract
The aim of the study is to determine the biological effectiveness of preparations (insecticides) against the eastern corn borer (Ostrinia furnacalis Guenee, 1854) and to assess their impact on the seed productivity of corn. The study was conducted in the fields of the laboratory of selection and primary seed production of corn of the Federal State Budgetary Scientific Institution Federal Scientific Center of Agrobiotechnology of the Far East named after A.K. Chaika in 2023–2024. The effectiveness was assessed: biological preparations – Biokill, KE (abamectin, 10 g/l), and Proclaim, VRG (emamectin benzoate, 50 g/kg); chemical – Espero, KS (imidacloprid,, 200 g/l + alpha-cypermethrin, 120 g/l) and Proteus, MD (thiacloprid, 100 g/l + deltamethrin, 10 g/l). Experimental design: 1 – control (treatment with distilled water); 2 – Proteus (0.5 l/ha, single treatment); 3 – Proteus (0.5 l/ha, double treatment); 4 – Biokill (0.4 l/ha, single treatment); 5 – Biokill (0.4 l/ha, double treatment); 6 – Espero (0.15 l/ha, single treatment); 7 – Espero (0.15 l/ha, double treatment); 8 – Proclaim (0.3 kg/ha, single treatment); 9 – Proclaim (0.3 kg/ha, double treatment). Plot area is 10.5 m2. Placement is systematic. Replication is threefold. Corn variety is Slavyanka. Observations and records were made in accordance with generally accepted me-thods. The preparation Proteus has a high biological efficiency against the pest with two-fold treatment of plants – 82 %, the bioinsecticide Biokill has the minimum with a single use (52 %). A positive effect of all the studied preparations on the seed productivity of corn was revealed. A significant increase (26.8 g, HCP05 = 15.4) in grain per 1 cob and the weight of 1000 grains (98 g, HCP05 = 19.0) compared to the control is provided by the insecticide Proteus with two-fold application.
