Abstract

 

Eco-friendly methods and strategies for nematode management have been recommended due to their non hazardous impact on environment. In this current study, experiment was conducted to control Meloidogyne incognita in tomato cv. ‘K25’ by using organic amendment as dip or soil-additive. The root-dip treatment ofJusticia adhatoda L. inhibited larval penetration in roots of tomato more than the root-dip of Lantana camara L. The standard concentration (s) proved to be more effective as compared to diluted concentrations. In another treatment, mixing organic residue of both test plants with soil at 0.5, 1.0 and 3.0% (w / w) 5 days prior to tomato transplanting, improved plant growth response and reduced root-knot development in roots at a 6 and 12% moisture levels. The 3% (w / w) of residue mix of J. adhatoda L. had phytotoxic effects on tomato. The 3% (w / w) of organic residue dosage of J. adhatoda L. at 12% moisture level caused minimum root-knot development in the roots of tomato. Therefore, the availability of these plant materials in tropical and subtropical regions of the world, especially developing countries will provide an economic and feasible means of controlling nematodes in vegetable crops.
