Bacterial pathogens of cassava manihot esculenta in the congo and the central african republic etiology epidemiology

, : Bacterial pathogens of cassava manihot esculenta in the congo and the central african republic etiology epidemiology. Agronomie (Paris) 1(9): 751-758

Two phytopathogenic bacteria, Xanthomonas manihotis (Arthaud-Berthet et Bondar) Starr, causal agent of the bacterial blight, and Erwinia carotovora Jones var. carotovora Dye, causal agent of soft rot of tubers, are recorded on cassava in Congo and Central Africa. Cassava bacterial blight, the most serious disease in the People's Republic of the Congo and in Central African Republic, develops preferentially in savanna areas. Forested areas are slightly or not contaminated. Symptoms of cassava bacterial blight include: angular leaf spots, leaf blight, wilting of young branches, gum exudation and tip die back. The disease appears and reaches its maximum intensity during the rainy season. In the dry season the manifestations of the disease slow down or even disappear. During this period it is always possible to isolate the parasite from the tissues of attacked plants. Tuber rot is a secondary disease which is not as severe as cassava bacterial blight.
