Mosaic disease of bottle guard [Lagenaria siceraria (Mol.) Standl] is one of the most important foliar diseases, causing significant loss in India. The pathogen has wide geographical distribution and has been reported in over 100 countries, including environments ranging from semi arid to tropical. It is the most widely distributed and important virus disease of cucurbits The field trial was conducted during Kharif season of 2015 to 2018 at RARI, Durgapura for the integrated disease management of mosaic disease in bottle gourd through different means and combinations among seven treatments. The minimum disease incidence (6.56%) and maximum yield (338.5 q/ha) were observed in treatment T₅(T₀+ Seed treatment with carbendazim 12%+ mancozeb 63% @ 3 g/kg and drenching of Captan 70% + Hexaconazole 5% WP @ 0.1% 15 days after germination followed by spraying of Tebuconazole 50% + Trifloxystrobin 25% @1g/l + spray with (Imidacloprid 17.8 SL @ 7.5 ml/ 15 l + Neem oil 0.2%) followed by Fosetyl-Al @ 0.1% followed by spraying of Tebuconazole 50% + Trifloxystrobin 25% @1g/l + spray with (Imidacloprid 17.8 SL @ 7.5 ml/ 15 l + Neem oil 0.2%) followed by Fosetyl-Al @ 0.1% at 10 days interval) while maximum disease incidence (40.13%)and minimum yield (225.7 q/ha)were observed in treatment T₇(Control). Natural products such as herbal extracts may provide alternatives to synthetic fungicides.
