The effect of two herbicides (paraquat and simazine on the antifungal activity of two fungicides (captan and mounsrin) against Rhizoctonia solani was studied. when the herbicides paraquat and simazine were applied to soil they altered the effectiveness of both fungicides in controlling R. solani , thus causing damping‐off of cotton. Both herbicides increased the toxicity of both fungicides against mycelial growth of the fungus. In pot tests, seeds or soil treated with captan or mounsrin, gave better control of R. solani damping‐off disease when the soil was treated with paraquat or simazine compared to untreated soil. Captan was, however, found to be more effective in controlling the disease than mounsrin.
