Snyder and Hansen” was carried out at Department of Plant Pathology, (J.N.K.V.V.), College of Agriculture, Jabalpur (M.P.) with the objective to record the incidence of Fusarium wilt of tomato in Jabalpur and Jhabua district and to evaluation of organic product, bioagents and chemicals against the isolated pathogen. Fusarium wilt of tomato was present in all the villages and block which surveyed. However, the incidence was not similar and it varied from place to place. The maximum incidence of Fusarium wilt of tomato was recorded in Panagar taluka in Mahgawan village which was 95%. There was noticeable difference on disease incidence between grafted (0%) and non-grafted (45%) methods. Minimum intensity of 54.32 per cent and 62.24 per cent was recorded while using FYM (Farm Yard Manure) with pre-composted deoiled sweet basil (Ocimum basilicum) leave SBL @25t/ha at 60 days and 90 days respectively. The minimum wilt intensity of 28.54 % (61.01% inhibition) and 50.06% (38.65% inhibition) was recorded recpectively at 60 and 90 days in treatment with use of FYM with Trichoderma viridae @ 5kg/ha + P. fluorenscens @ 5kg/ha. The minimum wilt intensity of 24.5% (64.73% inhibition) and 41.68 % (48.42 % inhibition was recorded recpectively at 60 and 90 days in treatment with use of Humic acid (400ppm) + (Pyraclostrobin + Epoxyconazole) (1000ppm). The maximum inhibition of 4.4 cm constituting 28.8 percent inhibition was recorded with use of FYM with SBL @ 25t/ha (100%). The maximum inhibition of 2.63cm constituting 57.44 percent inhibition was recorded with use of FYM with Trichoderma viridae @ 5kg/ha + P. fluorescence @ 5kg/ha. The maximum inhibition of 1.8cm constituting 71.48 percent inhibition was recorded with use of Humic acid (400ppm) + (Pyraclostrobin + Epoxyconazole) (1000ppm). The yield attributing parameters viz. Shoot length, root length, dry shoot weight, fresh shoot weight fresh root weight and dry root weight are significantly enhanced by the application of with FYM (Farm Yard Manure) with pre-composted deoiled sweet basil (Ocimum basilicum) leave SBL @25t/ha (100%). Among different bioagents with their combinations, maximum shoot length, root length, dry shoot weight, fresh shoot weight fresh root weightand dry root weight are significantly enhanced by the application of FYM with Trichoderma viridae @ 5kg/ha + P. fluorenscens @ 5kg/ha. Among different bioagents conventional chemicals with their combinations, maximum shoot length, root length, dry shoot weight, fresh shoot weight fresh root weight and dry root weight are significantly enhanced by the application of Humic acid (400ppm) + (Pyraclostobin + Epoxyconazole) (1000ppm).EnglishThesis
