Abstract:
Pod rot of mungbean caused by Fusarium incarnatum-equiseti is a newly emerged fungal disease of mungbean that caused bottleneck reduction in production. In the present study nine different fungicides viz. Carbendazim + Mancozeb, Tebuconazole + Trifloxystrobin, Azoxystrobin + Difenoconazole, Carboxin + Thiram, Metiram + Pyraclostrobin, Hexaconazole, Chlorothalonil, Propiconazole, and Tebuconazole were evaluated under in vitro conditions for their antifungal potential against Fusarium incarnatum-equiseti. The fungicides were tested at different concentrations i.e., 15, 25, 50, 100, and 150 ppm concentrations employing the “Poisoned Food Technique”. Among the fungicides, Tebuconazole and Propiconazole resulted in maximum mycelial growth inhibition with 80.23% and 74.13% at 150 ppm concentration, respectively. While the lowest percent inhibition was recorded in Hexaconazole 65.16 percent, over the control. Among the different combi fungicides, 100% inhibition of mycelial growth was recorded in Azoxystrobin + difenoconazole and Tebuconazole + Trifloxystrobin at 150 ppm followed by Carboxin + Thiram and Metiram + pyraclostrobin with 61.18% and 52.22%, respectively, and the least percent inhibition was observed in Carbendazim + mancozeb with 39.40% at 150 ppm concentration.
