Application of microbial plant protection products and bacterial fertilizers Planriz, Fitotsid, Diazofit and Fosfoenterin has reduced damage of pathogens in 1,6-2,9 times at processing tubers before planting, plants during budding and flowering, before laying on storage in Western Forest-steppe. Among the total number of diseases share a wet bacterial rot was 17,6-22,6%, Phoma spp. rot - 13,5-16,1%, Fusarium dry rot - 61,3-67,6%. In tubers planted in mid-May, the development of Fusarium spp. at the end of storage increased by 1.3-1.8 times compared with planting in late April.
