摘　　要： 对15个加工番茄品种进行了田间抗早疫病鉴定,结果表明,供试品种中无抗病品种,耐病品种6个,占40%;感病品种9个,占60%。对加工番茄早疫病菌进行了室内毒力测定和小区药效试验,室内毒力测定结果表明:72%锰锌·霜脲氰WP对菌丝生长抑制效果最好,EC50值为8.1μg/mL,70%代森锰锌WP、58%甲霜·锰锌WP、10%苯醚甲环唑WP次之,其它的药剂抑菌效果较差。小区药效试验结果表明:72%锰锌·霜脲氰的防治防效最好,可达81.2%,其次是10%苯醚甲环唑WP、70%代森锰锌WP、58%甲霜·锰锌WP,防效分别为73.1%、71.0%和61.0%。 Fifteen processing tomato varieties were identified for the early blight resistance identification in the farm.The results showed that there were no resistant varieties,and 6 varieties were tolerable account for 40%,9 varieties were susceptible accounting for 60%.The control efficacy of twelve fungicides to early blight of processing tomato with experiments of indoor toxicity trials and field trials were compared.Indoor toxicity trials shows that Cymoxanil mancozeb 72% WP was the most effective fungicide against the pathogen with EC50of 8.1 μg/mL,Mancozeb 70% WP,Metalaxyl·mancozeb 58% WP,Difenoconazole 10% WP,and others with a low effect.Field plot trials showed that the control effects of Cymoxanil mancozeb 72% WP was the highest,the control efficacy reached to 81.2%,Mancozeb 70% WP,Metalaxyl·mancozeb 58% WP and Difenoconazole 10% WP in turn,with the average control efficacy of 73.1%,71.0% and 61.0%,respectively.
