EPA Approves New Low-Volatile Dicamba Formulation
Soybean and cotton farmers have another low-volatile dicamba-tolerant herbicide to use in 2017 for soybeans and cotton.
The Environmental Protection Agency has registered DuPont’s FeXapan herbicide plus VaporGrip Technology. DuPont officials say FeXapan is a new dicamba formulation that significantly slices off-target movement potential compared with older formulations of dicamba. Vapor Grip is an additive that reduces volatilization.
DuPont officials say it is part of a complete Acre Solution with Pioneer soybeans with the Roundup Ready 2 Xtend trait. They add that the integrated seed and herbicide program approach, including preemergence residual herbicides, works to maximize efficiency and protect yields. FeXapan’s spectrum includes herbicide-resistant weeds like kochia, marestail, and amaranthus species like waterhemp and Palmer amaranth.
FeXapan joins two other dicamba-based herbicides that have been approved for use on soybeans with the Roundup Ready 2 Xtend trait. Federal regulators have approved Monsanto’s Xtendimax with VaporGrip. Its label includes nozzle specifications and currently allows no tankmix combinations.
Also approved is BASF’s Engenia, another dicamba formuation that is lower in volatility than existing ones. Company officials say Engenia has 70% lower relative volatility when compared with Clarity, an existing dicamba formulation. Engenia’s label also currently restricts tankmixes and nozzle selection.
Monsanto also has developed another herbicide for its dicamba-tolerant system that hasn’t yet received federal approval. Roundup Xtend is a premix of glyphosate and a low-volatile formulation of dicamba.
