Evaluation of Some New Generation Fungicides against Pigeonpea (Cajanus cajan (L.) Millsp.) Wilt Causal agent Fusarium udum under in vitro Conditions

Abstract

Pigeonpea wilt disease caused by Fusarium udum is one of the most devastating soil borne disease. The objective of this investigation was to determine the antifungal activities of fungicides which can be used to control wilt disease of pigeonpea. Among all the fungicides Azoxystrobin+Tebuconazole, Carbendazim, Tebuconazole+Trifloxystrobin, Hexaconazole, Tebuconazole exhibited 100% inhibition at all the concentrations, followed by Azoxystrobin+ Difenconazole which exhibited 92.22%, 94.4%, 94.4% and 100% inhibition at 250 ppm, 500 ppm, 750 ppm and 1000 ppm respectively.
