【Abstract】 Field surveys documented the dominance of monocotyledonous weed populations of Beckmannia syzigachne( Steud.) Fernald,Alopecurus japonicus and Sclerochloa kengiana and the dicotyledonous weeds,Stellaria media( L.)Cyr. and Galium aparine L. var. tenerum Gren. et( Godr.) Rebb in a wheat field in Taicang City. From 2013 to 2014,herbicide screening test were conducted on the dominant weed,B. syzigachne which also was the most difficult to control species. Fenoxaprop 6. 9% EW( Biaoma) and oxazoline o clodinafop 5% EC( Daneng) provided excellent control( above 90%) well above that achieved with other herbicides tested.更多还原
