DOI: 10.1002/ps.6838
Abstract: BACKGROUND The commercialization of dicamba-resistant soybean has resulted in increased concern for off-target movement of dicamba onto sensitive vegetation. To mitigate the off-target movement through physical drift, one might consider use of rope wicks and… read more here.
