摘要
不同药剂防治玉米粗缩病试验结果表明,药剂拌种和喷雾防治对玉米粗缩病均有一定的防控效果,其中以70%锐胜可湿性拌种剂拌种+10%吡虫啉可湿性粉剂225 g/hm2对水225 kg于玉米四叶期前喷雾防治效果最好,防效达78.03%;其次为10%吡虫啉可湿性粉剂225 g/hm2+20%盐酸吗啉胍水悬浮剂375 g/hm2于玉米四叶期喷雾;防效可达75.95%。
The results of different chemicals against maize rough dwarf virus showed that the ways of seeds mixed with pharmaceutical and spraying had certain control effects against maize rough dwarf virus. The controlling effect of 70% Ruisheng WP seed dressing agents ＋10% Imidacloprid WP 225 g/hm2 adding water 225 kg was best when spraying in four-leaf stage of corn ,was 78.03%, 10% Imidacloprid WP 225 g/hm2＋20% Moroxydine hydrochloride water suspension 375 g/hm2 was second when spraying in four=leaf stage of corn ,was 75.95%.
