Abstract:

A serious fungal disease of potato (Solanum tuberosum L.) was observed in Merowe and  Eldebba  localities, Northern state. The symptoms include Lesions begin as indefinite, water-soaked spots that enlarge rapidly into pale green to brownish-black lesions and can cover large areas of the leaf. During wet weather, lesions on the abaxial surface of the leaf vered with a gray to white moldy growth on the undersides of larger lesions, a ring of moldy growth of the pathogen is often visible. As the disease progresses, the foliage turns yellow and then brown, curls, shrivels, and dies. In stem  dark brown or black lesions develop in the cortical tissue near the soil line. The fungus, Phytophthora infestans,(Mont). de Bary) was consistently isolated from the affected seedlings and its pathogencity was confirmed in the seedlings of the potato cv. Belleni. Symptoms were reproduced by injected stem with pathogen suspension. This study reports for the first time the presence of Phytophthora infestans (Mont). de Bary)  in  the Northern Sudan causing  late blight disease in potato.
