Soil-applied broadleaf herbicides for weed management in dry beans (Phaseolus vulgaris L.) in Ontario are limited. Sulfentrazone is an effective broadleaf herbicide with some grass activity and is currently registered for use in soybean and some pulse crops in Canada. If registered for use in dry beans in Ontario, sulfentrazone would provide growers with another mode of action for broadleaf weed control. Five field studies were conducted over a two year period (2014–2015) to determine the tolerance of white beans to sulfentrazone applied pre-emergence (PRE) and if the spectrum of weeds controlled can be expanded by tank-mixing sulfentrazone with a soil-applied grass herbicide. Sulfentrazone (140 and 210 g ai ha^-1) was mixed with pendimethalin, dimethenamid-p, s-metolachlor or pyroxasulfone. All the tankmixes evaluated provided good control of green foxtail (Setaria viridis L.), pigweeds (Amaranthus powelli L. and A. retroflexus L.), and common lambsquarters (Chenopodium album L.), but only sulfentrazone pendimethalin had an adequate margin of crop safety. Based on this study, sulfentrazone combined with a grass herbicide provides acceptable control of some grass and broadleaf weed species; however, further research is required to determine if there is an adequate margin of crop safety for weed management in Ontario dry beans.
