DOW AGROSCIENCES SOLUTIONS FOR COTTON BOLLWORMS IN INDIA

摘要

India has the largest area under cotton in the world but has one of the lowest yields per unit area. It has many diverse production segments ranging from subsistence to high technology hybrids and genetically modified (GM) hybrids. Dow AgroSciences LLC (DAS) has a long history of exporting and marketing products to the Indian cotton farmers and is one of the leading insect solution companies today. Products targeting bollworms (Helicoverpa armigera, Spodoptera litura, Earias vittella and Pectinophoragossypiella) include chlorpyrifos, chlorpyrifos + cypermethrin, and spinosad. WideStrike~(R) is a new generation stacked trait that expresses Cry1F and Cry1Ac proteins in cotton. WideStrike~(R) varieties were grown commercially on a limited scale in the United States during 2005. The efficacy of WideStrike~(R) proteins against major cotton bollworms in India was studied. Initial observations from these studies and the potential for WideStrike~(R) in India will be discussed.
