Total six novel chemicals viz., Carbendazim (Bavistin), Hexaconazole (Convax plus), Tebuconazole (Folicur), Tebuconazole50%+ Trifloxystrobin 25% (Nativo), Fosetyl-Al (Aliette) and Fluopyram 17.7%+ Tebuconazole17.7% (Luna) were evaluated against Fusarium oxysporum f.sp. cubense TR4 at 50, 100, and 150 ppm concentration. Data revealed that the 100% inhibition was recorded in Tebuconazole50%+ Trifloxystrobin 25% even at 50 ppm followed by Fluopyram 17.7% + Tebuconazole17.7% and Tebuconazole with 100% inhibition over control at 150 ppm. The Minimum inhibition was found in the Carbendazim with 43.05% inhibition over control at 150 ppm. Same chemicals were tested at 0.2% concentration against Panama wilt of banana under pot condition in poly house. Among the novel chemicals, Tebuconazole 50% + Trifloxystrobin 25% was found most effective against Fusarium oxysporum f.sp. cubense TR4, in which wilt symptom was not observed up to 78 days after inoculation (DAI) in cv. Grand naine followed by Tebuconazole in which wilt disease was not found before 55 DAI while in Hexaconazole 52 DAI, Fosetyl-Al 50 DAI, Carbendazim 48 DAI whereas in Fluopyram 17.7%+ Tebuconazole17.7% wilt symptoms were appeared in 47 DAI. In control where no treatment was applied wilt symptom was seen in 21 days with a 96% wilt index. Maximum 77.09% inhibition over control was recorded in Tebuconazole 50% + Trifloxystrobin 25% followed by 52.09% in Fluopyram 17.7%+ Tebuconazole17.7%, 50.00% in Tebuconazole, 48.96% in Hexaconazole, 45.83% in Carbendazim and minimum 29.17% in Fosetyl-Al.
