Abstract: Fusarium oxysporum Schlecht was frequently isolated from roots of the okra plants showing wilting symptoms collected from Tando Allahyar. Pathogenicity test of F. oxysporum, was carried out by two methods (seed infestation and soil infestation method) on commonly growing okra variety Sabzpari. Between two methods of pathogenicity, soil infestation method produced maximum impact of the F. oxysporum on test plants. The plants inoculated by soil infestation method became more vulnerable to the pathogen and significantly showed minimum plant growth, seed germination as well as high recovery of a test pathogen as compared to the seed infestation method. Among six fungicides (Carbendazim, Topsin-M, Aliette, Copper oxychloride, Dividend Star and Dithane M-45), Carbendazim and Topsin-M appeared as highly effective at all used concentration, completely checked the mycelial growth of F. oxysporum, while other fungicides were effective at their higher doses only. The low concentrations of Topsin-M, Carbendazim and Aliette were performed well in promoting the shoot and root growth of the treated okra plants. However, all fungicides either more or less, significantly checked pathogen infection of okra plants grown in soil artificially infested with F. oxysporum as compared to the untreated plants.
