In vitro efficacy of fungicides against Fusarium solani incited by dry root rot of sweet orange

Fusarium is a large genus of filamentous fungi widely dispersed in soil and huge yield losses in crop plants. In present study eight different fungicides were evaluated in vitro at different concentrations viz., 500, 1000, 2000 and 2500 ppm against Fusarium solani by applying poisoned food technique. However, highest average mycelial growth inhibition was recorded with Carbendazim and SAFF (each 100 %). These were followed by the fungicides viz., Propiconazole (79.09 %), Hexaconazole % (72.15 %), Chlorothalonil (61.63 %), Mancozeb (49.15 %), Captan (40.86 %). The fungicide Benomyl was found comparatively less effective with minimum mycelial inhibition of 34.39 per cent.
