THE FEATURES OF POTATO TUBERS EPIPHYTIC MICROFLORA DURING STORAGE BY THE APPLICATION OF BIOLOGICAL PREPARATIONS

The using of biologiccal preparations Planryz, Diazofit and Fosfoenteryn reduce the tuber contamination by pathogens Fusarium and Alternaria sp. in 2,1-2,8 times compared to the control. It was established to reduce the number of pathogens in the composition of epiphytic microflora tubers of relatively resistant potato varieties Skarbnuza compared with relatively receptive Lileya. It was proved that using of Planriz + Ridomil Gold was more effective than one fungicide.
