摘　　要：Nine field trials (five with PPI and four with PRE herbicides) were conducted at Exeter and Ridgetown, Ontario during 2013 to 2015 to determine if the tolerance of white bean to preplant incorporated (PPI) and preemergence (PRE) herbicides is influenced by the herbicide carrier (water vs. UAN at 200 L&#8226ha^-1). There was no significant interaction between the carrier and herbicide for visible injury, plant stand, plant height, shoot dry weight, seed moisture content and yield. There was also no significant difference between the herbicide carriers for all parameters measured except for the shoot dry weight which was 6.5% greater when UAN was used as the carrier with PPI herbicides. Dimethenamid-p, pendimethalin, imazethapyr and halosulfuron applied PPI or PRE caused no visible injury except for imazethapyr PPI which caused 2% visible injury and dimethenamid-p PRE which caused 7% - 14% injury in white bean. There was no effect of the PPI and PRE herbicides evaluated on white bean stand, shoot dry weight, height, maturity and yield. Based on these results, using water or UAN could be used as the carrier for PPI and PRE herbicides in white bean.Nine field trials (five with PPI and four with PRE herbicides) were conducted at Exeter and Ridgetown, Ontario during 2013 to 2015 to determine if the tolerance of white bean to preplant incorporated (PPI) and preemergence (PRE) herbicides is influenced by the herbicide carrier (water vs. UAN at 200 L&#8226ha^-1).
