In vitro evaluation of fungicides and bioagents against Fusarium solani inciting wilt disease of cluster bean

Abstract

Fusarium wilt of cluster bean caused by Fusarium solani is a major threat to profitable cultivation. A comprehensive study was conducted to evaluate disease management strategies. Among the eleven fungicides such as Carbendazim 50% WP, Tebuconazole 25.9% EC, Hexaconazole 4% + Zineb 68% WP, Carbendazim 12% + Mancozeb 63% WP, Carboxin 37.5% + Thiram 37.5% WS, Captan 70% + Hexaconazole 5% WP each @ 0.1% and 0.2% concentration were found most significantly effective in inhibiting the mycelial growth of F. solani with 100% inhibition over control. Among six bioagents tested Bacillus subtilis (78.81%) and Trichoderma harzianum (68.89%) inhibit the maximum mycelial growth of Fusarium solani.
