Abstract
The effectiveness of the insecticofungicide Prestige, KS, used to protect plants from damage by diseases and damage by pests in the first stages of ontogenesis is shown. Presowing seed treatment with a preparation with a flow rate of 2.5–3.5 l/t reduced the incidence of winter wheat with root rot of rhizoctoniosis etiology by 62.9%. The biological effectiveness of the Prestige, KS (3.5 l / t) on moderately infectious background was also quite high - 59.5%, however, it was 9.0% lower than the standard. It practically did not influence overwintering of plants. After application of Prestige, KS were in the norm of 2.5 and 3.5 l/t, and Maxim Extreme, KS in the norm of 1.75 l/t, the number of plants preserved by spring varied from 91.9 to 92.9%, that is higher than in the control by 3.9–4.9%. The application of insectofungicide Prestige, KS at a rate of 2.5 l/t on spring wheat sowings reduced the number of grain fleas by more than 80.0%and the damage of the stems by the larvae of cereal flies by 74.3%. This preparation is not phytotoxic with respect to cereals.
