Description
The aetiology and epidemiology of leaf blight of centro (Centrosema pubescens Benth) was investigated at Ibadan in the lowland humid tropics of Nigeria. Rhizoctonia solani was associated with the leaf blight of centro. The pathogen was harboured by itchgrass (Rottboellia cochinchinensis (Lour) Clayton), a weed growing within and outside the centro plot. High inoculum population of 4.0 + 0.3 x 106/g soil was estimated in the soil. The seed of centro were free of R. solani. Field infection of the disease occurs during the peak of the rainy season beginning in patches which later spread causing extensive defoliation of the sward.
