In this experiment, different districts of South Gujarat were closely examined for the presence of wilt disease in different cultivars/ Bt hybrids during the crop season to know the current scenario of wilt disease. The respective FOV wilt pathogen was purified, identified and isolated. Here, different combi fungicides were tested for their effect on the growth of Fusarium oxysporum f. sp. vasinfectum (FOV) using poisoned food technique. The technique involves cultivation of test organism on a medium containing the test chemicals. In this experiment, PDA was used as basal medium. Six combination products of fungicides were evaluated at three different concentrations by poisoned food technique for evaluating their efficacy against the Fusarium oxysporum f. sp. vasinfectum. Among them, combination products of fungicides, carbendazim 12% + mancozeb 63% significantly inhibited the growth of the Fusarium oxysporum f. sp. vasinfectum and proved strongly fungitoxic in nature.
