为科学防控枣果真菌病害提供用药指导,采用生长速率法,研究了生产上7种常用化学杀菌剂扑海因、世高、多菌灵、代森锰锌、百菌清、甲基托布津和多抗霉素对枣果3种主要致病真菌链格孢菌、实腐茎点霉和七叶树壳梭孢的室内毒力作用。结果表明:链格孢菌对扑海因极其敏感,其次为世高;实腐茎点霉对多菌灵和扑海因极其敏感,其次为多氧霉素(其半数致死量为0.01μg /mL);七叶树壳梭孢对多菌灵、甲基托布津和多抗霉素敏感。
為科學防控棘果真菌病害提供用藥指導,採用生長速率法,研究瞭生產上7種常用化學殺菌劑撲海因、世高、多菌靈、代森錳鋅、百菌清、甲基託佈津和多抗黴素對棘果3種主要緻病真菌鏈格孢菌、實腐莖點黴和七葉樹殼梭孢的室內毒力作用。結果錶明:鏈格孢菌對撲海因極其敏感,其次為世高;實腐莖點黴對多菌靈和撲海因極其敏感,其次為多氧黴素(其半數緻死量為0.01μg /mL);七葉樹殼梭孢對多菌靈、甲基託佈津和多抗黴素敏感。

The efficacies of seven commouly used fungicides in prduction (iprodione, difenoconazole, carbendazim, mencozeb, chlorothalonil, thiophanate-methyl and ployoxin B) against three causal agents of jujube fruit diseases, Alternaria alternata, Phoma destructiva and Fusicoccum aescul were compared in laboratory toxicity experiments using growth rate method to provide a medication guide for the prevention and control fungal diseases of jujube fruit.The results indicated that iprodione had significant inhibitory against colony growth of Alternaria alternata, and difenoconazole was followed.Carbendazim, iprodione and polyoxin B had significant inhibitory against colony growth of Phoma destructiva, polyoxin B was followed and the half lethal dose of it was 0.01 μg /mL.Carbendazim, thiophanate-methyl and polyoxin B had significant inhibitory against colony growth of Fusicoccum aescul.
