Abstract
Isolate T95 of Trichoderma sp. Isolated from soil has shown the antagonistic action against the pathogen of Botrytis cinerea Pers. In solid culture medium. Antagonistic action showed parasitism and competition between isolate T95 and the above pathogen. Effective were 6×106/ml conidia ; The control experiment in the fields showed when effective inhibitory concentrations of isolate T95 were 5×106/ml conidia,it was the most effective in greenhouse experiments to against Botrytis cinerea Pers. and it′s control efficiency was more than 80.9%.
