The effectiveness of the of biologics and biostimulants use on winter wheat Moscow 39

The purpose of the research is to study the effect of new protective agents, including biostimulants, on the growth, development and yield of winter wheat. The research was carried out at the research and educational experimental center of the "Integration" of the Orel State Agrarian University named after N.V. Parakhin. New and recommended fungicide Amistar Extra, SC, biofungicide Vitaplan, SP, biostimulants Nigor+ and Nigor++, winter wheat Moskovskaya 39 were used as objects of research. The location of plots is systematic. The size of the experimental plot is 12 x 20 = 240 m2. The size of the accounting plot is 50 m2. The repetition of the experience is threefold. 2 treatments were carried out: 1 - tilling phase-the beginning of the exit into the tube: 2 - the phase of the flag sheet. For all variants of the experiment, the following pesticides were used: Insecticide Zalp, CE (250 g/l cypermethrin) - 0.2 l/ha (working fluid - 200-300 l/ha). Herbicide Lornet, BP (300 g/l of clopyralide) - 0.16-0.66 (r.zh. - 200-300 l/ha). The predecessor of winter wheat is buckwheat. Plowing to a depth of 23-25 cm. Early spring harrowing. Pre-sowing cultivation. The seeding rate is 5 million germinating seeds. The infestation of plants with diseases and the structure of the crop were determined according to the Methodology of the State Variety Testing of agricultural crops (1982, 1995). When determining the quality of grain, we were guided by the relevant GOST standards. It was revealed that double treatment of winter wheat crops of the Moskovskaya 39 variety contributes to an increase in grain yield in the variant with Nigor+ and Nigor++ - by 7.9%, under the influence of Vitaplan - by 10.5% and the greatest increase was noted when treated with the systemic fungicide Amistar Extra - 18.4%. Under the influence of all drugs, the quality of grain and its nutritional value have improved. The best results were obtained when crops were treated with preparations of biological origin Nigor+, Nigor++ and Vitaplan.
