An extensive survey of downy mildew ( Sclerospora graminicola ) incidence on pearl millet ( Pennisetu mglaucu m) grown in farmers’ fields was undertaken in 2002 in pearl millet-growing areas of Nigeria – the Sahel, Sudan Savanna, northern Guinea Savanna and southern Guinea Savanna agroecological zones. Downy mildew incidence was assessed on two types of pearl millet “gero” and “maiwa” and in 32 locations in these zones. Incidence in “gero” millet was the highest in Sudan Savanna and the lowest in the Sahel zone. Cropping pattern and seed rate affected incidence of the disease which was highest in the fields with pure stand than mixed stand cropped with legumes
