The efficiency of the use of biopreparations in increasing winter wheat resistance to the stress

The article discusses ways to increase winter wheat resistance to the factors, the current state of systemic measures for plant protection, taking into account the introduction of new elements of technology. It is noted that timely techniques, in a certain sequence and mutual connection with the biological characteristics of the culture, contribute to the intensification of the agro-industrial production. In solving problems associated with increasing the immune status of plants in the autumn-winter-spring period, it is necessary to reveal the general patterns, features of the development of winter wheat, physiological and biochemical processes, as well as the requirements for environmental factors and the response to their changes. To obtain a high-quality and stable harvest from year to year, it is necessary to use a complex of agricultural practices. The technology should always be specific for the region, zone, farm, field, taking into account the adjustment for the local soil and climatic conditions. The main elements of the adaptive technology include: variety selection, placement of crops in crop rotations, leveling of the soil surface, biological substantiation of sowing dates, crop formation, biological and phytosanitary control, an integrated system of plant protection against diseases, pests, weeds, lodging, choice of a method of grain harvesting, assessment of wheat fields for grain quality. The use of biological products in the treatment of seeds and crops has a positive effect on plant survival and the renewal of spring vegetation. When calculating the duration of the interfacial periods of the experimental variants, it was noted that the period of grain filling was about 40 days, which is 3-5 days more than that of the control sample. The introduction of the developed method of pre-sowing treatment with biological products, spraying of seedlings reduces the development of septoria and rust.
