摘要：

In vitro sensitivity assays of nine isolates belonging to five Trichoderma species, to ten demethylation inhibitor fungicides, showed highly significant differences among both isolates and fungicides. Isolates of T. koningii were the most tolerant to fungicides. Flutriafol, fenarimol and myclobutanil were the least effective in inhibiting growth of Trichoderma isolates. UV mutants resistant to prochloraz or bromuconazole from a wild-type isolate of T. harzianum were obtained. Cross-resistance between prochloraz and bromuconazole was evident in four of the five representative mutants tested. Some mutants showed reduced growth and sporulation. Overall results suggest a good potential for integration of Trichoderma isolates and DMI-fungicides in integrated plant protection schemes. Copyright (C) 1996 Elsevier Science Ltd
