摘　　要：为探讨10%双草醚悬浮剂（农美利）在南方直播水稻田中的安全性及其对杂草的防效,特进行了直播早稻田和中稻田杂草的田间药效试验。结果表明,农美利与对照药剂稻杰一样,对水稻直播田稗草、鸭舌草、陌上菜、节节菜、异型莎草等杂草有较好的防除效果,对直播水稻安全无药害;建议在水稻直播田除杂草时,农美利的有效成分用量为22.5-30.0 g/hm2,在水稻播后3叶期以上、杂草2-4叶期时,对茎叶喷雾防效最佳。Field trialsofsafety and weed controleffectof10% bispyribac sodium（Nominee）SC were conducted respectively in directsowing early-rice and semilate-rice fields. Its weed-preventing and eliminating effect is good for barnyard grass, M onochoria vaginalis,Lindernia procumbens,Rotalaindica,Cyperusdifformisand otherweeds,with no chemicalinjury to rice plants.Itsuggeststhatthe dosage ofNominee’s main active ingredientshould be 22.5~30.0g/hm2 forthe weed controlin directsowing rice field.At3-leafstage ofrice and/or2~4-leafstage ofweed,the stem-leafspray controleffectis the optimum.
