US EPA allows sulfoxaflor use on sorghum in nine states
The US EPA has granted emergency exemptions to allow the use of Dow AgroSciences' insecticide, sulfoxaflor (trade-marked as Isoclast), for the control of sugar cane aphids (Melanaphis sacchari) on sorghum in nine states. The state authorities in Arkansas, Florida, Georgia, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee and Texas asserted that without the use of the insecticide uncontrolled aphid infestations would likely result in significant economic losses. They pointed to the presence of a new pest or a new biotype of M sacchari that could not be controlled with pesticides registered for use on the crop. The EPA has approved the request and established temporary tolerances that expire on December 31st 2017. It granted a similar exemption for Texas last year. Dow received US approval for the sulfoxaflor-based insecticides, Transform and Closer, for use on a wide range of crops in 2013.
