Efficacy of Novel Fungicides against the Fusarium oxysporum f.sp. cubense Causing Panama wilt of Banana

Abstract

Panama wilt of banana caused by Fusarium oxysporum f.sp. cubense TR4 is considered as most devastating disease of bananas. In Bihar, this disease became a menace to banana growers of Bihar due to introduction of new highly virulent strains i.e.TR 4 strain B2. The objectives of this study were to evaluate newly available fungicides under in vitro and in vivo conditions for the efficient management of the Panama wilt of banana. Fourteen different fungicides and novel chemicals were tested in vitro as well as in vivo conditions. Native (tebuconazole 50% + trifloxystrobin 25%) was found to exhibit 100% inhibition over control in vitro whereas in pot conditions 86.2% inhibition over control was observed against Fusarium oxysporum f.sp. cubense TR 4 strain B2 in cultivar Alpan (AAB).
