摘要: 为了解常用杀菌剂对马铃薯干腐病的防效,采用含毒介质法测定了7种供试药剂对干腐病菌主要种群茄病镰刀菌(Fusarium solani)的毒力,并经接种病原菌于薯块和药剂浸泡的方法测定了供试药剂对干腐病的防效。得出的结果为:氟硅唑和苯醚甲环唑抑菌效果最好,EC50分别为3.47μg/m L、3.80μg/m L;异菌脲和甲基硫菌灵效果最差,EC50分别为436.5μg/m L、186.21μg/m L;恶霉灵、多菌灵、百菌清的EC50分别为40.74μg/m L、70.79μg/m L和79.43μg/m L,效果较好。对马铃薯干腐病的防治效果由高到低依次为:恶霉灵、多菌灵、苯醚甲环唑、氟硅唑、百菌清、甲基硫菌灵、异菌脲,其防效分别为70%、62.50%、53.30%、48.30%、47.50%、43.70%、12.50%。

Abstract: Potato dry rot by Fusarium solani is one of the most common and severe disease in storage. Laboratory toxicity of seven fungicides to this pathogen was tested with method of contained fungicide in medium and field control efficacy were determined by soaking inoculated potato with seven fungicides. In results, flusilazole and difenoconazole had the best inhibition effect with EC50 of 3.47 μg/m L、3.8 μg/m L. The second were Hymexazol, carbendazim and chlorothalonil with EC50 of 40.74 μg/m L, 70.79 μg/m L and 79.43 μg/m L. Thiophanate-methyl and iprodione had the lowest inhibition effect at EC50 of 436.5 μg/m L and 186.21 μg/m L. The field control efficacy of seven fungicides hymexazol, carbendazim,difenoconazole, flusilazole, chlorothalonil, thiophanate-methyl, and iprodione were 70%, 62.50%, 53.30%, 48.30%, 47.50%,43.70%, 12.50% respectively.
