Abstract

Field experiments conducted over a 7-yr period have demonstrated that common buckwheat (Fagopyrum esculentum Moench. cv. ‘Mancan’) has acceptable tolerance to many herbicides that are known to selectively control grass-type weeds in broadleaf crops. Herbicides for broadleaf weed control that showed some selectivity in common buckwheat were desmedipham {ethyl [3-[(phenylamino) carbonyl] oxy] phenyl] carbamate} applied postemergence and fluorochloridone {3-chloro-4-(chloromethyl)-1-[3-(trifluoromethyl)phenyl]-2-pyrrolidinone} applied either preplant soil incorporated or preemergence shallow incorporated. Tank mixtures of desmedipham plus sethoxydim {2-[1-(ethoxyimino)butyl-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} also showed adequate tolerance to common buckwheat at rates recommended for weed control in other crops.
