摘要
通过田间药效试验,比较不同除草剂对当前南疆地区冬麦田播娘蒿、萹蓄、硬草等杂草的防除效果,为科学、安全、高效应用除草剂提供依据。结果表明,药后50 d,10%苯磺隆可湿性粉剂18.0 g a.i./hm2+5%唑啉草酯·炔草酯乳油37.5 g a.i./hm2、75%苯磺隆水分散粒剂18.0 g a.i./hm2+10%乙羧氟草醚乳油12.0 g a.i./hm2+5%唑啉草酯·炔草酯乳油37.5 g a.i./hm2、37%炔·苄·唑草酮可湿性粉剂166.5 g a.i./hm2对播娘蒿的株防效、鲜质量防效均为100%,对萹蓄的鲜质量防效均在92%以上,对硬草的株防效、鲜质量防效均在88%以上,且对小麦生长安全。
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%.
