Abstract
Relevance. One way to increase the productivity and quality of potatoes is to use biological products. They have the ability to influence the immune potential of plants, disease resistance, which in turn affects the yield and quality of tubers. Methods. We have studied the effect of two biological preparations Flavobacterin and Mizorin, as well as their combined effect on the growth and development of potato plants. Results. Treatment with biological products at different stages of development increased the rate of development of potato plants during seedlings by 10-20%, but in the phase of budding and flowering, these differences were smoothed out. The highest yield increase of 1.3 t/ha was noted in the variant with joint processing (Flavobacterin + Mizorin), where the yield was 17.8 t/ha. The quality indicators of tubers treated with drugs did not have a significant impact, however, they significantly affected the prevalence of diseases. So, pre-planting treatment of potato tubers and treatment of potato plants during the growing season with biological preparations increases disease resistance during storage: mushroom from 0.7 to 4.0%. The safety share of healthy potato tubers was 80-95%, and 75% without treatment.

Summary
Одним из способов повышения продуктивности и качества картофеля является использование биологических препаратов. Они обладают способностью влиять на иммунный потенциал растений, на устойчивость к болезням, что в свою очередь влияет на урожайность и качество клубней. Изучено влияние двух биологических препаратов Флавобактерин и Мизорин, а также их совместное воздействие на рост и развитие растений картофеля. Обработка биопрепаратами на разных стадиях развития повышала скорость развития растений картофеля в период всходов на 10–20%, но в фазе бутонизации и цветения эти различия сглаживались. Наибольшая прибавка урожайности в 1,3 т/га была отмечена на варианте с совместной обработкой (Флавобактерин+Мизорин), где урожайность составила 17,8 т/га. Предпосадочная обработка клубней картофеля и обработка растений картофеля в период вегетации биологическими препаратами повышает устойчивость к болезням во время хранения. Доля сохранности здоровых клубней картофеля составила 80–95%, а без обработки – 75%.
