“Fall Armyworm: Towards Sustainable Management by Smallholders in Africa” presented by Allan Hruska, Principal Technical Coordinator for Fall Armyworm for the Food and Agriculture Organization of the United Nations
Fall Armyworm (Spodoptera frugiperda) (FAW) is an important crop pest in the Americas, especially in tropical and sub‐tropical areas where it can overwinter. FAW was confirmed in Africa in early 2016 and has quickly spread across Sub‐Saharan Africa and beyond. Recently it has been confirmed in India and Yemen. It is now infesting tens of millions of acres of maize across Africa, and rapidly moving on to sorghum and millets. In the USA and South America, FAW has been largely controlled with Bt‐corn over the last 20 years. Corn farmers in Sub‐Saharan Africa are largely smallholders – over 98% of Africa’s corn farmers grow small plots (typically less than two acres), often in multi‐crop systems, use saved seed, use few inputs or machinery, and use most of the harvest for family consumption. Less than 10% use pesticides in their corn crop. So most African corn farmers couldn’t afford high‐technology management options. FAO has been working with smallholders, their organizations, and with support of many governments, to help innovation of locally available, sustainable management practices for FAW. Many of these practices have their basis in traditional cropping systems of Mesoamerica (plant diversity, importance of natural enemies), as well as innovations discovered and tried by smallholder corn farmers around the world. The knowledge and practices used and being tried for sustainable FAW management by smallholders will be presented.
