摘　　要：探讨了排草丹、农美利、稻杰等3种药剂防除水花生、三棱草、鸭舌草、牛毛毡、稗草、丁香蓼、节节菜等水稻田常见杂草的效果。结果表明,48%排草丹水剂有效成分1200g/hm2时可有效防除这几种常见杂草,药后41d时,除对水花生的防效比农美利处理组低外,对其他几种杂草的防效均优于另2种药剂,且持效期较农美利和稻杰长。48%排草丹水剂可作为湖北荆州地区防除水稻田常见杂草的药剂推广。Effects of 3 kinds of herbicides including Basagran,Nominee,Penosulam to control the common weeds in rice field such as Alligator Alternanthera,Difformed Galingale,Sheathed Monochoria,Needle Spikesedge,Barnyardgrass,Climbing Seedbox,Indian Rotala Herb were stuided.The results showed that 48% Basagran at the active ingredient concentration of 1200 g/hm2 could control the common weeds effectively,the effect of Basagran was higher and the persistence was longer than the other two herbicides except the effect on Alligator Alternanthera.48% Basagran was worth extending largely as herbicide to control the common weeds in rice fields in Jingzhou of Hubei Province.
