• EPA conditionally approved a new Bacillus thuringiensis (Bt) plant-incorporated protectant in cotton (WideStrike®) for use until Sept. 30, 2009. Dow Agrosciences’ WideStrike® cotton is expected to have environmental and public health benefits by reducing the use of conventional chemical insecticides that may be applied to cotton several times per season. WideStrike® cotton contains Cry1Ac and Cry1F proteins, both previously approved by the EPA. These proteins are intended to control tobacco budworm, pink bollworm, cotton bollworm, cabbage looper, saltmarsh caterpillar, cotton leaf perforator, soybean looper, beet armyworm, fall armyworm, yellowstriped armyworm and European corn borer.
