The U.S. Environmental Protection Agency (EPA) has granted an emergency use exemption in Louisiana and Oklahoma for the application of Transform WG insecticide. The Section 18 label, also recently granted in the state of Texas, was issued specifically for control of sugarcane aphids in sorghum.

The pest was detected in 38 counties throughout Louisiana, Texas and Oklahoma in 2013. The infestation spread quickly and yield losses from 25 percent to 50 percent were recorded.  All sorghum-growing counties in the region are at risk and further expansion is possible in 2014. Sugarcane aphids thrive in drought conditions and mild winters help them survive.

Transform, from Dow AgroSciences, is a fast-acting insecticide from a proprietary, new class of chemistry that controls sap-feeding insects, such as aphids. It offers a short 7-day pre-harvest interval for forage and 14-day pre-harvest interval for grain. Transform also has a short 24-hour re-entry interval and has minimal impact on beneficial insects.

Transform can be applied up to two times at a rate of 0.75 to 1.5 ounces per acre in each application for control of sugarcane aphid. Applicators applying Transform for sugarcane aphids must have a copy of the Section 18 emergency use exemption label, which expires on Oct. 31, 2014.
