摘要

Tomato (Solanum lycopersicum L) is most widely cultivated solanaceous vegetable crop in the world. Wilt disease caused by Fusarium oxysporum f.sp. lycopersici (Sacc) Synder and Hans {FOL) is a serious constraint in the production of tomato and causesconsiderable yield losses in many states of the India. In vitro and disease control experiments were conducted to evaluate bio-efficacy of different organic bio-formulations, neem based formulations, de-oiled cakes and biocontrol agents either alone andin various combinations to develop organic management practices for tomato wilt during Kharif seasons (2017 and 2018). In vitro tests indicated that among the three neem-based formulations, three organic bio-formulations and five de-oiled cakes extracts;Achook @ 2.0 per cent concentrations; Jeevamrut and de-oiled neem cake mixture extract @ 30 per cent concentration were highly inhibitory to F.o. f.sp. lycopersici. Trichoderma viride and Pseudomonas fluorescens showed effective antagonistic activitiesin suppression of FOL. In disease control experiment, treatment modules comprising soil application of de-oiled neem cake mixture plus FYM (10+10g kg"1 soil) enriched with T. viride and P. fluorescens each @ 2 per cent was found best effective in suppression of wilt disease (PDI 13.7%; PEDC 76.6%) followed PDI 15.1 per cent and PEDC 74.2 per cent in module comprising soil application of de-oiled neem cake mixture (20 g kg"' soil) enriched with T. viride and P. fluorescens each @ 2 per cent and both themodules were statistically significant and at par with chemical check i.e. seed and seedling dip treatment with carbendazim @ 0.10 per cent (PDI-12.1%; PEDC 79.2%). Determination of population density revealed that disease suppression was due to reduction in population count of the pathogen by biocontrol agents and antimicrobial activities of organic bio-formulations in all the treatments compared to the inoculated untreated control.
