Abstract:
Leaf blight caused by Myrothecium roridum is a devastating disease of Bael in nursery stage. The experiments were conducted to test the efficacy of fungicides against Myrothecium roridum causing leaf spot of bael in in vitro condition. The results showed that the complete (100%) mycelial growth inhibition was recorded with Tebuconazole (50%) + Trifloxystrobin (25%) 75 WP @ 0.05%, Carbendazim (12%) + Mancozeb (63%) @ 0.2%, Propiconazole (25%) EC @ 0.1%, Tebuconazole (25%) EC @ 0.2% and Carbendazim 50% WP @ 0.1%. The minimum mycelial growth (mm) and maximum growth inhibition at 24 day after inoculation was Hexaconazole (5%) EC @ 0.1% (39.66mm and 55.93%) followed by Mancozeb (75%) WP @ 0.2% (45.66mm and 49.26%) and Azoxystrobin (18.2%) + Difenconazole 11.4% SC @ 0.2% (50.33mm and 44.07%). Maximum mycelial growth was found in control (90.00).
