STUDY OF PLANT BIOPREPARATIONS TREATMENT EFFECT WITH HOT MIST IN THE PERIOD OF VEGETATION
Biological preparations are used to disinfect seeds and prevent mass infection. This also contributes to intensification of plant growth. It is proposed to treat potato seed tubers with hot mist of biopreparations Potassium humate and Fitosporin M before planting on a conveyor-loader using a hot mist generator. To stimulate plant growth after treatment with herbicides, it is proposed to carry out inter-row treatment with hot mist of biopreparations using a special device for potato treatment. To evaluate the development of plants, the stem height of potato bushes was measured and the number of leaves was counted. Results are presented as stacked histograms. The reliability and reproducibility of the data obtained was evaluated using Cochran criterion. The experimental data did not exceed the table value of Cochran criterion Kkt = 0.54. Studies carried out with potatoes of "Lily" variety showed that the treatment with hot mist of Potassium humate caused an increase in the stem height by 13.6 % and the number of leaves - by 14.2 %. Pre-treatment of potato seed tubers with hot mist of biopreparations and plant treatment during the growing season contributed to the accelerated development of the vegetative mass in earlier periods, that increased the resistance of plants under unfavorable conditions
