摘　　要：[Objectives]The paper was to search for biopesticides with good control effect on grape gray mold.[Methods]A randomized field trial was carried out to compare the control effects of 100 million CFU/g Trichoderma harzianum WDG,200 million spores/g Trichoderma WP,24% validamycin AS,0.3% matrine AS on grape gray mold.[Results]Of the 4 biopesticides,200 million spores/g Trichoderma WP had the highest control effect on grape gray mold,with the control effect of 73.38% at 7 d post the second application,significantly higher than those of 100 million CFU/g T.harzianum WG and 0.3% matrine AS;the control effect was 75.77% at 14 d post the second application,significantly higher than those of other 3 biopesticides.[Conclusions]The 200 million spores/g Trichoderma WP shows a good control effect on grape gray mold with a long-lasting control effect,so it is more is for the control of summer black grape gray mold in Jianshui County.
