Tens of millions of smallholder farmers across Africa are facing a new foe in their fields: the Fall Armyworm (FAW). Newly arrived from the Americas, this insect prefers to eat maize, but can live on over 80 plant species. Farmers are alarmed by the ragged maize leaves in their fields caused by the FAW larval feeding, and worry about yield losses and their food security. The good news is that smallholder farmers in the Americas have been managing FAW for centuries. Lessons learned from them, as well as advances in technologies, were tried and tested by experts and master trainers from Farmer Field Schools across Africa to craft the newly-launched “Integrated Management of the Fall Armyworm on maize” guide. The guide provides many examples of field studies, experimentations and exercises that can be done with farmers in Farmer Field Schools and in short field trainings. It includes detailed practical guidance on organizing training courses for extension workers and farmers on the integrated management of the Fall Armyworm.
