System uses plants to lure fall armyworm away from maize fields

Climate conditions in Nepal are suitable for the establishment of fall armyworm, which could cause considerable crop loss if not managed properly. The fall armyworm is a destructive pest that has a voracious appetite for maize and other crops. Through the Nepal Seed and Fertilizer (NSAF) project, the International Maize and Wheat Improvement Center (CIMMYT) is working with the government of Nepal and other partners to address this imminent threat.

Chemical control of fall armyworm is too expensive and impractical for small-scale farmers, has negative human health effects, and can be a source of soil pollutants with a negative effect on biodiversity.

CIMMYT is currently evaluating the efficacy of push-pull cropping systems to control fall armyworm. Considered one of the most climate-smart technologies, push-pull systems use plant-pest ecology instead of harmful chemical insecticides to control weeds and insects. It is an environmentally friendly pest control method which is also economically viable for maize producers.
