  Description

  The article gives the results of the three years of research to identify the main species composition of fungal pathogens when stratified open and closed methods. Biological efficiency of Guapsin, 0,2%, and Trichodermin, 0,5% is shown. During the period of stratification, using an open method "on the water", the following pathogens have evolved: Cladosporium herbarum (18,6%), Trichotecium roseum (16,3%), Phomopsis viticola (13,9%), Alternaria spp. (13,4%), Penicillium sp. ( 9,1%), Aspergillus sp. (5,6%), Pythium sp. (4,3%), Gonatobotrys flava (4,3%), Mycelia sterilia (2,8%), Botrytis cinerea (2,2%). The studies found that the close method of stratification in the peat developed the following specific composition of pathogens: Penicillium spp. (21,1%), Phomopsis viticola (16,4%), Botrytis cinerea (15,3%), Trichotecium roseum (11,1%), Alternaria spp. (8,2%), Mycelia sterilia (1,0%). During the period of stratification, biological efficiency Guapsin, 0.2%, and Trichodermin, 0,5%, was 31,9-88,0% and 28,2-86,3%, respectively
