METHOD OF BIOLOGICAL CONTROL OF ALTERNARIA OF GRAPE

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture, in particular, to viticulture. In the process against the pathogen Alternaria tenuissima (Kunze ex Pers.) Wiltshire the biofungicide based on antagonist fungus Trichoderma viride Pers. ex S.F. Gray strain 4097 is used, the titer is at least 1.0×10⁹ CFU/ml. The consumption rate of biofungicide is 1.5-3.0 l/ha. Processing is carried out by blocks: the first is carried out prior to harvesting to suppress the current infection, and the second is after harvesting to reduce the accumulation of infection.;EFFECT: method enables to increase efficiency and environmental safety of control of Alternaria, to reduce phytotoxic effect of treatments to maintain the plants immunity through the use of biological defense technology.;1 dwg, 2 tbl, 2 ex
