| dc.description.abstract | ABSTRACT The research explorations entitled ‘Role of Botanicals in Management of Meloidogyne incognita (Kofoid and White) Chitwood associated with Tomato (Solanum lycopersicum L.)’ were undertaken to record the efficacy of certain botanicals known to possess nematicidal principles in different forms against Meloidogyne incognita infecting tomato crop. In all, nine plants viz., Azadirachta indica (Neem), Calotropis procera (Calotropis/ aak), Lantana camara (Lantana), Parthenium hysterophorus (Congress grass), Tagetes erecta (African marigold), Allium sativum (Garlic), Duranta erecta (Duranta), Melia azedarach (Darek) and Ricinus communis (Castor) were used during the present studies. In vitro studies regarding effect of aqueous leaf/seed extracts of referred plants at one, two and five per cent concentrations on juvenile hatch from egg mass revealed garlic clove extract at five per cent to be the best egg hatch inhibitor closely followed by calotropis leaf extract. However, at lower concentrations aak leaf extract was more effective than garlic clove extract. On the other hand, among the leaf extracts neem caused highest per cent mortality of J2s under in vitro conditions at all durations of exposure followed by calotropis, parthenium, tagetes and lantana in decreasing order of efficacy. Among seed extracts, garlic at five per cent concentration was the most effective causing cent per cent mortality within 120 hours. In a pot experiment, seedling root dips in five per cent extracts of referred plants separately, followed by their transplanting in nematode infected soil applied with respective extracts produced the best results showing improvement in vegetative growth and tomato fruit production and reduction the soil populations of the juveniles and root galling significantly with respect to control. The highest yields were attained in treatments receiving garlic clove or neem leaf extract. In a field experiment with dried powders of six plants, soil treatment with dried neem leaf powder produced most vigorous plants that yielded highest quantum of fruits followed by calotropis, castor, lantana, parthenium and duranta in decreasing order of efficacy. | en_US |
