Abstract: Tomato (Lycopersicon esculentum Miller) crop suffers from several diseases, among which wilting caused by Fusarium oxysporum f. sp. lycopersici is one of the serious diseases observed regularly in tomato growing areas. Therefore, efforts were made to evaluate the efficacy of different systemic fungicides in vitro against Fusarium oxysporum f. sp. lycopersici by poisoned food technique. Among the seven systemic fungicides tested in vitro, against Fusarium oxysporum f. sp. lycopersici, carbendazim and hexaconazole at all three different concentrations (@ 500, 1000 and 1500 ppm) showed complete (100%) mycelial inhibition, followed by tebuconazole (95.06%), difenconazole (92.65%), propiconazole (89.94%) and thiophanate methyl (62.28%), respectively. The pyraclostrobin was found less effective with 44.93% mycelial inhibition over untreated control.
