Abstract
The research was carried out in order to find ways to optimize the system of protection of spring wheat crops. In the conducted studies, the effect of combinations of sodium selenite and various pesticides, differing in the specifics of action and biological activity, on the yield and quality of spring wheat of the Yubileinaya 80 variety was studied. Currently, there is a need to achieve a sufficient effect of the action of chemical plant protection products and to obtain a minimum impact on human health and the environment. The purpose of the research is to study the influence of various combinations of chemical plant protection products and methods of using sodium selenite on the yield and grain quality indicators of spring wheat variety Yubileinaya 80. The studies were carried out under the conditions of a vegetative experiment with spring wheat variety Yubileinaya 80. Two methods of using sodium selenite and chemical plant protection agents of different specifics of action were studied: fungicide, herbicide, and insecticide, which were applied in different combinations and at different times. As a result of the studies, the phytotoxicity of the studied preparations of chemical plant protection was revealed, which apparently manifests itself as a result of inhibition of the morphometric indicators of the growth of the root system and vegetative organs of wheat plants, resulting in a violation of the processes of accumulation of assimilates and their outflow to the reproductive organs. Optimal combinations of pesticides and sodium selenite have been established, allowing to obtain reliable changes in yield and quality indicators of wheat grain. It was revealed that the use of selenium treatment before sowing seeds contributed to a decrease in the phytotoxicity of the studied pesticides, as a result of stimulating the processes of absorption by plants and the redistribution of nitrogen to the reproductive organs of wheat, which had a positive effect not only on the yield and quality of spring wheat of the Yubileynaya 80 variety, but also on the external surface microstructure of the fruit shell of the grain. The noted features of the surface of the fruit shell of the grain will reduce losses during grain processing and obtain processed products from such grain of higher quality.
