doi:10.11924/j.issn.1000-6850.casb16080001

Abstract

Abstract: In production, the selection of fungicides to control konjac gray mold that caused by Botrytis cinerea was in chaos, toxicity of fungicides against B. cinerea was not clear. Therefore, the toxicity of 7 fungicides against B. cinerea was tested by mycelium growth rate method. The results showed that carbendazim and iprodine had the best inhibitory effect on mycelial growth of B. cinerea , with the EC 50 value of 0.001 and 0.005 mg/L; then were ningnanmycin, pyrimethanil and dimethachlon, which had good inhibition rates, with theEC 50 value of 0.043, 0.052 and 0.084 mg/L; the inhibitory effect of copper oxychloride and copper calcium sulphate were the worst, with theEC 50 value ≥ 200 mg/L.
