Bollworm infections cause severe damage to cotton crops in the region. The level of damage varies from year to year depending on environmental conditions. After hatching, the larvae move quickly into the bolls, where they are protected from insecticide sprays. This does not stop farmers from trying to control insect infections using vast quantities of insecticide. Introducing the Bt toxin into the plant itself affects only feeding insect larvae and targets the pests as they begin to feed on the crop. The toxin is completely safe for all other non-Lepidopteran animals including humans. Bt cotton has the potential to provide effective bollworm control and is a much more environmentally friendly farming method.
