摘要：Field trials were conducted in 1998 and 1999 at two locations near Novi Sad,to evaluate efficacy of single and sequential applications of glufosinate-ammonium in Liberty Link maize.Glufosinate-ammonium (800 g a.i./ha,2x400 g a.i./ha and 2x500 g a.i./ha) controlled grasses: Echinochloa crus-galli (74-100%),Setaria glauca (86-100%),Setaria viridis (84-99%),Digitaria sanguinalis (77-100%) and broadleaf weeds: Amaranthus retroflexus (93-100%),Amaranthus blitoides (90-100%),Chenopodium album (84-100),Xanthium strumarium (100%),Polygonum persicaria (94-100%),Solanum nigrum (100%),Datura stramonium (99-100%),Convolvulus arvensis (74-100%) and Portulaca oleracea (100%).Abutilon theophrasti was more difficult to control with glufosinate-ammonium than other annual broadleaf weeds.Glufosinate-ammonium was similar or more effective in weed control than practical rates of rimsulfuron + dicamba,primisulfuron + prosulfuron + nicosulfuron and nicosulfuron + dicamba.Sequential application (early postemergence) were more effective than single post-emergence application on controll of Sorghum halepense from rhizome (98-99%) and annual weeds.Sequential application of glufosinate-ammonium and rimsulfuron controlled similarly Sorghum halepense from rhizome.
