In vitro efficacy of fungicides against Fusarium oxysporum f. sp. ciceri

Abstract

Six systemic, six non-systemic and six combi fungicides were evaluated in vitro against Fusarium oxysporum f. sp. ciceri; All fungicides tested in vitro were found effective in inhibition of mycelial growth of Fusarium oxysporum f. sp. ciceri. Among systemic fungicide, Carbendazim and Tebuconazole were highly effective in arresting the mycelial growth of Fusarium oxysporum f. sp. ciceri with complete inhibition of pathogen at all tested concentration of 250, 500 and 1000 ppm. Among non systemic fungicide, the least radial mycelial growth with maximum inhibition of pathogen was recorded with Captan followed by Mancozeb at all concentration of 1000, 1500 and 2000 ppm. Combi products of fungicide viz., Carbendazim + Mancozeb, Tebuconazole + Trifloxystrobin and Carboxin + Thirum inhibited the complete growth of pathogen at all tested concentration of 1000, 1500 and 2000 ppm.
