摘要
试验结果表明，１８％杀虫双撒滴剂在水稻田二化螟１～２龄高峰期进行防治，具有优良的防治效果。每６６７ｍ２用撒滴剂１５０、２００、２５０、３００ｍｌ的校正防效分别为８６１％、９１３％、９６９％、９７４％。当撒滴剂用量增加到２５０ｍｌ／６６７ｍ２以上时，其校正防效和保苗效果明显高于１８％杀虫双水剂３５０ｍｌ、９２％杀虫单可湿性粉剂５０ｇ的防效和保苗效果。
The result of field trial showed that 18% Shachongshuang spray-drop solutions had good control effect when it was used in the peak stage of Chilo suppressalis (Walker)1～2 instar in rice field.Correction control effect of spray-drop solutions 150,200,250,300ml per 667m2 was 86.1%,91.3%,96.9%and 97.4%,respectively.when it was used more than 250ml/667m2,its correction control effect and seedling protecting effect were obviously better than that of Shachongshuang aqueous solutions 350ml and 92% Shachongdan WP 50g.
