Pathogenicity of 21 isolates of Macrophomina phaseolina was tested on three cotton cultivars under greenhouse conditions. Analysis of variance (ANOVA) showed that the main effects of both isolates (P= 0.000) and cultivars (P= 0.000) were very highly significant sources of variation in post-emergence damping-off and survival. Isolate x cultivar interaction was also a significant source of variation in post-emergence damping-off (P= 0.03) and survival (P= 0.04).
