| Abstract: | A field test was conducted to compare the efficacy of several herbicides on weeds including Descurainia sophia L.Schur,Polygonum aviculare L.and Sclerochloa kengiana Tzvel.in winter wheat in southern Xinjiang.At 50 days after treatment,the herbicides mixtures of tribenuron-methyl 10%WP （18.0 g a.i./hm2 ） ＋traxos 5%EC containing 2.5%pinoxaden ＋2.5%clodinafop-propargyl （37.5 g a.i./hm2）,tribenuron-methyl 75%WG （18.0 g a.i./hm2） ＋flu-oroglycofen-ethyl 10%EC （12.0 g a.i./hm2 ） ＋traxos 5%EC （37.5 g a.i./hm2 ） and clodinafop-propargyl· bensul-furon-methyl· carfentrazone-ethyl 37%WP （166.5 g a.i./hm2 ） were all selective to winter wheat and provided 100%and more than 88%control of D.sophia and S.kengiana based on plant number and fresh weight,respectively,whereas the control of P.aviculare based on weight was more than 92%. |
