US OK for DuPont's safer maize herbicides
DuPont has received US approval for two safened versions of established sulfonylurea maize herbicides. Accent Q (nicosulfuron 54.5%) and Steadfast Q (nicosulfuron 25.2% + rimsulfuron 12.5%) contain Bayer CropScience’s safener, isoxadifen-ethyl, to enable use under a wider range of conditions and on more maize hybrids. “Accent Q and Steadfast Q herbicides offer consistent weed control with crop safety,” says DuPont’s maize portfolio manager, Jeff Carpenter. Bayer agreed to supply DuPont with isoxadifen-ethyl for use in US maize herbicides in 2006 ( Agrow No 504, p 1).
