Experiments were conducted at Sartingal farm of Regional Horticulture Research Sub- station (RHRSS) Bhaderwah, Doda, SKUAST-Jammu in randomized block design with fifteen treatments in three replications to assess the losses caused due to fusarium wilt of tomato using a susceptible variety. Different fungicides, bio-agents and cultural practices, alone and in possible combinations gave the significant reduction in tomato wilt disease incidence caused by Fusarium oxysporum f. sp. lycopersici and also significantly increased the yield over the check. Among the treatments, seedling treatment with carbendazim @ 0.1% + Soil drenching with carbendazim @ 0.1% three times was most effective, recording the lowest disease intensity (11.33%), recording 70.27% reduction in disease severity over the check. Accordingly, tomato fruit yield was also highest in T9 (133.65 q/ha), which recorded 91.61% increase in fruit yield over T15 check (69.75 q/ha). This was followed by T10 (Seedling treatment with carbendazim @ 0.1% and soil drenching with carbendazim @ 0.1% two times at 15 days interval starting at the age of 21 days after transplanting), that recorded 13.69% wilt incidence and fruit yield of 119.95 q/ha and T13 (T1 + T2 + T4 + T6), which too recorded fruit yield at par with T10 (118.18 q/ha).
