摘  要:
采用生长速率法测定了几种内吸性杀菌剂对甜瓜枯萎病菌的毒力。试验结果表明,多菌灵和氟硅唑的毒力最高,其EC50分别为2.2671mg/L和13.3418mg/L;而且枯萎病菌对多菌灵和氟硅唑的敏感性也较高;多菌灵和氟硅唑对枯萎病菌的联合毒力测定结果表明,两种药以6:1和1:6混配,具有增效作用。

摘  要:
Based on the mycelium growth rate,the toxicity of several systemic fungicides were tested against Fusarium oxysporum f.sp.melonis.The results showed that carbendazim and flusilazole had the best toxicity against Fusarium oxysporum f. sp. melonis,and their EC50 were 2.267 1 mg/L and 13.341 8 mg/L,respectively.F.oxysporum f. sp. melonis was highly sensitive to carbendazim and flusilazole.The synergic toxicity tests showed that the mixed preparation of carbendazim and flusilazole had synergistic effect at the ratio of 6:1 and 1:6.
