Abstract
To investigate the indoor antifungal activity of different fungicides to Botrytis cinerea Pers. in strawberry,we determined the indoor toxicity of 10 kinds of fungicides to strawberry B. cinerea by using mycelium growth rate method. The results showed that the EC50values of Carpropamid,Prochloraz,Diethofencarb,Cyprodinil,Procymidone,Iprodione,Diniconazole,Carbendazim,Pyrimethanil and Boscalid were 0. 0494,0. 0636,0. 1064,0. 1389,0. 1442,0. 2799,0. 7301,0. 7902,2. 1407 and 2. 7545 μg / mL,respectively. There was great difference in sensitivity to strawberry B. cinerea among 10 kinds of fungicides,and strawberry B. cinerea was the most sensitive to Carpropamid.
