Seven systemic and non-systemic fungicides were screened at different concentrations (100, 500, 1000 & 2000 ppm) in vitro and in vivo to test their efficacy against Rhizopus Rot of tomato. In vitro fungitoxicity test indicated that the benomyl, Carbendzim12% +Mancozeb 63% (75 WP), Trifloxystrobin25% + tebuconazole 50% (75 WG) and thiophanate methyl 70 WP at different concentrations (100, 500, 1000 & 2000 ppm) were highly effective and resulted in complete mycelial growth inhibition of Rhizopus oryzae. The lowest Rhizopus rot severity was observed in fruits treated with benomyl at 100 & 500 ppm, trifloxystrobin (25%) + tebuconazole (50%) at 1000 and 2000 ppm concentration followed by carbendazim (12%) + mancozeb (63%) (6.21 & 0.45 and 7.49 & 7.49%) at 500 and 1000 ppm both in Pre-and Post-inoculation at 5 ᵗʰ day after inoculation, respectively. Carbendazim (61.11 & 24.99% and 51.48 & 49.54%) found least effective against Rhizopus rot at 100 and 500 ppm on 5th day after inoculation.
