As fall armyworm continues to threaten food security in Africa, the use of Bt maize offers significant potential to manage the pest. But it will be critical to manage resistance via multi-toxin crop varieties and appropriate use of refuge planting—all in forms accessible to the smallholder farmers that grow nearly all of Africa’s maize.
On smallholder farms using Bt maize in Africa, the combination of reduced field size and multiple pests presents challenges to insecticide resistance management. A new report in the open-access Journal of Integrated Pest Management offers recommendations for best practices.
By Josh Lancette When using Bt crops, a constant concern is preventing insect pests from becoming resistant. According to a paper published in the Journal of Economic Entomology that contains […]
Previous studies from China, Spain, and the United States on genetically modified (GM) rice, cotton, and maize have concluded that the biodiversity of insects and related arthropods in GM crop […]
