Grain sorghum producers in four Southern states will again have Transform available to help manage sugarcane aphid infestations.
The U.S. Environmental Protection Agency, in response to states’ requests, has granted Section 18 emergency use exemptions for Alabama, Arkansas, Georgia and Texas for application of Transform WG. Section 18 approvals are pending in five other states, according to Dow AgroSciences, producer of Transform.
Dow describes Transform as a fast-acting insecticide from a proprietary class of chemistry introduced commercially in 2013 in cotton, potatoes, canola, soybeans and other crops. Last year, Section 18s were granted in several states for control of sugarcane aphids in sorghum.
Sugarcane aphids first appeared in sorghum in 2013, mostly in Texas and Louisiana, and by last year spread to 300 counties and parishes in 12 states. The insect pest feeds on plant sap, causing foliage to turn purple and yellow and reducing yield. The aphid also produces a sticky honeydew that collects on leaves and stalks, creating reduced harvest efficiency and clogged combines.
