Farmers who grow cereal crops in most African countries are all too familiar with the challenges presented by striga, a parasitic plant also known as witchweed that infests farmers’ fields and causes lower yields, or even no harvest at all. Now African scientists are breeding maize that can resist this pest plant as extension agents are offering farmers various solutions for improving yields in areas where the invasive weed is especially prevalent.
