摘要

There <span style="font-family:Verdana;">are</span><span style="font-family:Verdana;"> a limited number of soil-applied herbicides available for broad-spectrum</span><span style="font-family:;" "=""><span style="font-family:Verdana;"> weed control in dry bean production in Ontario, Canada. Four experiments were conducted from 2017 to 2019 in southwestern Ontario to compare the efficacy of six soil-applied grass herbicides [trifluralin (600 g ai ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;">), ethalfluralin (810 g ai ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;">), pendimethalin (1080 g ai ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;">), S-metolachlor (1050 g ai ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;">), dimethenamid-p (544 g ai ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;">) and EPTC (3400 g ai ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;">)] and halosulfuron (35 g ai ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;">) applied alone and in combination, applied preplant incorporated (PPI), on white bean tolerance and yield, and weed control efficacy. There was no white bean injury from the herbicide treatments eva</span><span style="font-family:Verdana;">luated. Grass herbicides (trifluralin, ethalfluralin, pendimethalin, S-metolachlor</span><span style="font-family:Verdana;"> dimethenamid-P and EPTC) controlled velvetleaf 0% - 82%, pigweeds 87% - 99%, common ragweed 0% - 93%, common lambsquarters 81% - 99%, wild mustard 0% - 71%, barnyardgrass 98% - 100% and green foxtail 98% - 99%. Halosulfuron controlled velvetleaf 98%, pigweeds 94%, common ragweed 90% - 94%, common lambsquarters 97%, wild mustard 98% - 100%, barnyardgrass 19% - 24% and green fo
