以72%杜邦克露可湿性粉剂、72%杜邦克露可湿性粉剂加37.5%泉程悬浮剂、58%诺毒霉可湿性粉剂、68%金雷多米尔水分散粒剂马铃薯在不同出苗时期(出苗后30d、出苗后20d和40d各喷1次)喷洒防治马铃薯晚疫病。试验结果表明,用72%杜邦克露可湿性粉剂加37.5%泉程悬浮剂在马铃薯出苗后20d和40d各喷1次效果最好,马铃薯晚疫病防治效果高达98.9%,值得在冬种马铃薯生产中使用。
Four different kinds of pesticide, Du Pont 72% cymoxanil mancozeb wettable powder, Du Pont 72% eymoxanil mancozeh wettable powder mix with Quaneheng 37.5% copper hydroxide suspending agent, Nuodumei 58% metalaxgl mancozeb wettable powder and Jinleiduomier 68% mefenoxam maneozeh aqueous dispersion granule, were used to control potato late blight by spraying the pesticides on the twentieth, thirtieth and fortieth day respectively after emergence of seedlings. The results showed that spraying Du Pont 72% cymoxanil mancozeb wettable powder mix with Quaneheng 37.5% copper hydroxide suspending agent on the twentieth and fortieth day after emergence of seedlings, achieved the best result, which has 98.9% of control effect on potato late blight.
