Abstract: Eight fungicides were evaluated in vitro and in vivo against of Fusarium oxysporum f. sp. capsici, causal agent of Fusarium wilt of bell pepper. Mycelial growth of pathogen was significantly inhibited by all tested fungicide. carbendazim at 50, 100, 150 ppm and tebuconazole + trifloxystrobin at 500 ppm were found most effective and resulted in complete inhibition in mycelial growth of the pathogen. mancozeb was found to be less effective as compared to others and resulted in 51.85 per cent mycelial growth inhibition even at high concentration of 750 ppm. Under field evaluation of fungicides against Furasium wilt disease of bell pepper, all fungicides reduced disease incidence compared to the untreated control. Soil drenching of carbendazim (0.2%), carbendazim + mancozeb (0.25%) and tebuconazole + trifloxystrobin (0.1%) were found most effective in reducing the disease completely and increasing the fruit yield. mancozeb was found least effective with 58.83 per cent reduction in disease.
