在秧苗移栽后３ｄ，每公顷用８０％稻思达水分散性粒剂９０ｇ有效成分，或８０％稻思达水分散性粒剂６０ｇ有效成分＋１０％吡嘧黄隆可湿性粉剂１９．５ｇ有效成分，对水稻移栽田中的稗草、千金子、碎米莎草和鸭舌草等杂草的防效可达９０％以上，对水稻生长安全，水稻产量比对照提高１１％以上。
The control effects of oxadiargyl and its mixture on weeds in rice field were tested. Oxadiargyl 80% WG at 90 gAI·hm -2 or its mixture at 60 gAI·hm -2 with pyrazosulfuron ethyl 10% WP at 19 59 gAI·hm -2 at 3 day after the transplantation of seedling had significant effect of controling Echinochloa crusgalli, Leptochloa chinensis, Cyperus iria and Monochoria vaginalis .The control efficacy of these treatments was over 90%.
