Effect of Delivery Systems of Pseudomonas fluorescens on the Rhizosphere Survival and Management of Fusarial Wilt of Tomato

Pot experiments conducted to evaluate different delivery systems for Pseudomonas fluorescens in the management of fusarial wilt of tomato revealed that FYM enriched with P. fluorescens as seed and soil application was very effective in minimizing wilt incidence to 15.53 per cent. Carbendazim at 0.1% recorded 18.56% disease incidence and the untreated control recorded the maximum disease incidence of 38.25%. Significantly highest population of P. fluorescens was recorded when FYM enriched with P. fluorescens was used for seed treatment and soil application (30 × 10 7 CFUs g -1 ) on 60 days after sowing and the same treatment recorded the lowest population of Fusarium oxysporum f. sp. lycopersici (8.9 × 10 2 CFUs g -1 of soil).
