摘要: 在生产上防治魔芋灰霉病发生的药剂种类选择混乱,及很多药剂对魔芋灰霉病菌的毒力作用也不明确,因此采用菌丝生长速率法测定了7种杀菌剂对魔芋灰霉病菌的毒力。结果表明,多菌灵、异菌脲对魔芋灰霉病菌的抑制效果好,EC50分别为0.001、0.005 mg/L;其次是宁南霉素、嘧霉胺、菌核净,EC50分别为0.043、0.052、0.084 mg/L;王铜和硫酸铜钙的抑菌效果最差大于200 mg/L。

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.
