摘　　要：[Objective] The paper was to isolate Colletotrichum sp.from strawberry and to screen effective fungicides.[Method] The indoor toxicity of 7 fungicides to Colletotrichum sp.was measured by growth rate method.The potted control effect of 3 fungicides on Colletotrichum sp.was evaluated.[Result] Fludioxonil exhibited the highest indoor toxicity to Colletotrichum sp.,with the EC50 value of 0.117 mg/L,and the EC50 value of prochloraz and difenoconazole were 0.141 and 0.357 mg/L,respectively.The pot experiment showed that the potted control effect of 20% fludioxonil2 000 times dilution on Colletotrichum sp.was the highest of 92.86%.450 g/L prochloraz EW 4 500 times dilution and 250 g/L difenoconazole EC2 500 times dilution also received high control effects against Colletotrichum sp.,which were 91.68% and 89.29%,respectively.[Conclusion] Fludioxonil,prochloraz and difenoconazole could be used for the control of strawberry anthracnose.
