Abstract

Twelve isolates of Fusarium spp., incitant of cowpea wilt were studied for their morphological, cultural and pathogenic variability. Among the isolates, F7, F8, F10 and F11 were non – pathogenic whereas all others were wilt producing type. The growth rate of the isolates varied from 0.86-1.42 cm/day. Macro conidia produced were falcate, fusoid to sub cylindrical, mostly 3-5 septate and the size ranged from 18.8-7.9 x 3.3-1.8 ?m in size. Microconidia were oval to ellipsoidal, cylindrical, straight or curved. Intercalary and terminal chlamydospores were observed among the isolates.
KEY WORDS: Fusarium spp., Variability, Pathogenic, Morphological, Cultural, Cowpea.
