e0“the addition of dicamba to glyphosate at either the early-postemergence (EPOST) or mid-postemergence (MPOST) timing provided greater control and density reduction of GR giant ragweed than glyphosate alone”

Other claims from this paper (8)
- Intervention effect All herbicide treatments controlled glyphosate-resistant giant ragweed by 91 to 100% at 3 weeks.
- Intervention effect Preplant flumioxazin plus dicamba plus glyphosate gave greater giant ragweed control than the 2,4-D combination.
- Intervention effect Delaying dicamba from early to mid postemergence did not alter giant ragweed control or density reduction.
- Intervention effect Sequential dicamba plus glyphosate gave 88 to 89% waterhemp control versus 24% for sequential glyphosate.
- Intervention effect Sequential dicamba plus glyphosate reduced waterhemp density by 90% versus 42% for sequential glyphosate.
- Intervention effect Acetochlor added at early or late postemergence did not improve waterhemp control or density reduction.
- Intervention effect Preemergence flumioxazin plus chlorimuron followed by dicamba plus glyphosate, with or without acetochlor, improved waterhemp control over early postemergence comparators.
- Recommendation Appropriately timed dicamba once or sequentially can be part of integrated resistant weed management in soybean.
