摘　　要：为探讨水稻水直播稻田抗药性稗草的防除方法,采用25 g/L五氟磺草胺可分散油悬浮剂(稻杰)、10%双草醚悬浮剂(农美利)和50%二氯喹啉酸可湿性粉剂(沙稗丰)进行了不同配方的田间药效试验。结果表明:该试验田块稗草对稻杰、农美利、沙稗丰的抗药性高,建议在防除该类抗药性稗草时,水稻催芽播种后0~3 d土壤喷雾处理300 g/L丙草胺乳油(扫茀特)100 mL/667 m^2,水稻3~4叶期茎叶喷雾处理100 g/L氰氟草酯乳油(千金)或10%噁唑酰草胺乳油(韩秋好)100 mL/667 m^2,能有效防除此类抗药性稗草。To study the methods of Barnyardgrass(Echinochloa crus-galli)control,which have Resistance to three herbicides like penoxsulam(25g/L.OD),bispyribac-sodium(10%.SC)and quinclorac(50%WP),we do an experiment with different herbicide formulations.The results showed that the Barnyardgrass has high resistance to Penoxsulam,bispyribac-sodium and quinclorac.We Recommend that when controlling this kind of Barnyardgrass,spray to soil with pretilachlor(300g/L.EC)1.5L/hm2after the germination period0-3d and cyhalofop-butyl(100g/L.EC)or metamifop(10%.EC)1.5L/hm2to the foliage in the3-4leaves stage,which could effectively control the resistance of the barnyardgrass.
