US herbicide restrictions on soybean cultivation comes into force
The product cannot be applied in Minnesota after June 20.
The Minnesota restriction is in addition to those established by the US Environmental Protection Agency (EPA). The affected formulations are XtendiMax, Engenia, FeXapan and Tavium.
Dicamba is most effective early in the growing season. Product labels recommend application on small broadleaf weeds that are up to four inches tall.
To manage weeds after cut-off times, herbicides from Group 9 (products containing glyphosate), Group 2 (such as Pursuit, Classic, FirstRate), and Group 14 (such as Flexstar, Cobra, Cadet, Ultra Blazer) can be used.
If growers have herbicide resistant weeds such as waterhemp, follow the University of Minnesota Extension recommendations on layering of residual herbicides such as Dual, Outlook, Warrant, and Zidua.
In Minnesota, the XtendiMax, Engenia, FeXapan, and Tavium formulations of dicamba are “restricted use pesticides” for retail sale to, and for use only by, certified applicators who have complete dicamba or auxin-specific training.
