Abstract
The present study explores the potential of different organic amendments i.e. vermicompost, spent compost mushroom, calotropis leaf extract, panchgavya and Trichoderma against tomato fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici in pots under greenhouse conditions. The population of F oxysporum f. sp. lycopersici was significantly reduced after application of organic amendments. Drenching of soil with Trichoderma asperellum @10 g-1 + Chitosan @ 0.1% (T3) recorded lowest percent disease index (34.40 %) and was at par with chemical control with carbendazim @ 0.1%. Treatment (T1) soil application of FYM + Trichoderma asperellum @ 2% w/w and (T2) vermicompost @ 2 % w/w were also effective in minimizing the disease and PDI recorded at 43.30 and 46.63, respectively. Panchgavya @ 30 per cent was also at par with vermicompost recording 49.96 per cent PDI. Maximum PDI was recorded in control (73.30%).
