Downy mildew, caused by Sclerospora graminicola, is one of the most important pearl millet diseases. It is widely distributed in the temperate and tropical areas of the world and has been reported in 51 countries. In Africa, the disease is found in all pearl-millet producing countries such as Senegal, Sierra Leone, Niger Republic, Ghana, Nigeria, Benin Republic, Cameroon, Zimbabwe, Zambia, Tanzania, and many others. Yield losses in pearl millet attributed to downy mildew varies with location, variety, and season. In Nigeria, grain yield losses caused by this disease range from 50 to 70%. The most striking symptom of the disease is green ear, and two plants in five are found to produce the green ear symptom.
