Tenth US state gains Isoclast exemption for sorghum

The US EPA has approved an emergency exemption to allow the use of Dow AgroSciences' insecticide, Transform (sulfoxaflor - trade-marked as Isoclast), in Kansas for the control of sugar cane aphids (Melanaphis sacchari) on sorghum. That brings the number of states with emergency exemptions for this use to ten. The Agency previously granted exemptions in Arkansas, Florida, Georgia, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee and Texas. Sugar cane aphids first appeared on sorghum in 2013, mostly in Texas and Louisiana, and by 2014 had spread to 12 states. "As sugar cane aphids continue to migrate farther north, sorghum growers in affected states need an effective tool to combat the devastating impact of this pest," says Dow product manager Todd Pilcher. The company received US approval for the sulfoxaflor-based products, Transform and Closer, for use on a wide range of crops in 2013.
