‘Fighting Striga’ may not be a Hollywood – or even Nollywood – blockbuster but it is set to grab the attention of farmers throughout Africa.
Scientists have invested heavily over the past 40 years to fight one of the world’s most troublesome weeds, Striga. This parasitic weed seriously damages maize, sorghum, millet, rice, and fonio. While developing Striga-resistant varieties is a key area of research, insights into how soil fertility management and other options can help to reduce Striga infestation proved hard to communicate effectively with farmers.
In 2006, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) embarked on farmer field schools and came up with practical integrated Striga and soil fertility management practices for pearl millet and sorghum. A scarcity of skilled trainers, however, made it hard to maintain quality while scaling up.
