Abstract

The aetiology of a leafspot disease of pearl millet (Pennisetum americanum [P. glaucum]) in Zimbabwe was investigated using Koch's postulates. Bipolaris sp., Exserohilum sp. and bacteria, were isolated from lesions, but only bacterial isolates produced the original symptoms following inoculation of a susceptible pearl millet line, 852B. Biochemical and physiological tests, including LOPAT, indicated that the bacterium was the fluorescent pseudomonad, Pseudomonas syringae. This represents the first report of P. syringae on pearl millet in Africa
