In vitro assessment of fungicides against Fusarium oxysporum f. sp. pisi causing Fusarium wilt of pea

Abstract

The present study was designed to evaluate the antifungal effect of six different fungicides viz., Carbendazim, Copper oxychloride, Captan, Thiophanate methyl, Ridomil, and Carboxin + Thiram. The evaluation was carried out at different concentrations i.e., 0.025%, 0.05%, 0.1%, 0.2% and 0.4% against mycelial growth of Fusarium oxysporum f.sp. pisi (FOC) by “poisoned food technique”. Results obtained on in vitro evaluation revealed that all the test concentrations of all fungicides significantly inhibited growth of (FOC) as compared to control. It was observed that the pathogen could not grow at all different concentrations viz., 0.025%, 0.05%, 0.1% and 0.2% in Carbendazim, yielded 100 per cent inhibition of mycelial growth of the pathogen and least inhibition was observed with Copper oxychloride (1.15 per cent) at 0.05% concentration. On the basis of available information and preliminary study, it is suggested that Carbendazim can be used in the management of Fusarium wilt of pea.
