Pearl Millet Diseases
Questionable and Poorly Described Diseases

Alternaria Leaf Spot

Alternaria alternata (Fr.) Keissler was isolated in India from pearl millet samples (either leaf spots or head mold, not clearly stated) and inoculated back onto pearl millet. Scattered oval to irregularly shaped lesions developed on the leaves. Lesions were copper red with black in the center and varied from 5 to 20 mm in diameter. This disease has been reported once (Gaikwad and Rane 1977) and may be an artifact of controlled inoculations.
