As a result of the widespread reports of damage, the EPA quickly enacted changes for dicamba use in 2018, including making these products restricted-use, requiring stricter record-keeping and ordering additional spray drift mitigation measures.
The EPA issued several amendments to the XtendiMax, Engenia and FeXapan labels that will impact all purchases and applications of these products in 2018 and beyond. These amendments, as summarized by Aaron Hager, weed specialist at the University of Illinois, include:
1 XtendiMax, Engenia and FeXapan are now restricted-use products, permitting only certified applicators to purchase and/or apply these products.
2 Prior to applying these products in 2018…
