摘要
通过苯醚·咪鲜胺35%水乳剂对黄瓜靶斑病进行田间药效防治试验,结果表明:在黄瓜靶斑病发生中前期,喷施苯醚.咪鲜胺35%水乳剂750、500、300倍液防治黄瓜靶斑病,药后5d,防效分别为63.55%、70.03%和70.63%;间隔7d进行2次施药,药后7d,防效分别为51.63%、61.62%和62.05%。苯醚.咪鲜胺35%水乳剂500、300倍液和对照药剂多抗霉素3%可湿性粉剂300倍液对黄瓜靶斑病的防治效果相当,都显著高于750倍液。该药剂可以做为防治黄瓜靶斑病的重要轮换产品,进行推广应用,且对黄瓜安全性良好。
The effects of Difenoconazole.Prochloraz 35% EW for the control of Corynespora cas- siicola were carried out. At the initial and middle stage of Corynespora cassiicola, the efficacy of the Difenoconazole-Prochloraz 35% EW diluted to 750, 500, 300 times were 51.63%, 61.62% and 62.05% respectively after five days; the second spraying after seven days, the efficacy were 51.63%, 61.62% and 62.05% respectively after seven days. The effects of Difenoeonazole- Prochloraz 35% EW diluted to 500, 300 times and Polyoxin 3% WP diluted to 300 times were similar, and they are better than the 750 times. This fungicide could be extended for the control of Corynespora cassiicola and it was safe to cucumber.
