Application of Methanolic Extracts of Botanicals for the Management of M. incognita Infecting Tomato and Chilli

Leaf extracts of two plants such as Murraya koenigii L. Spreng and Vitex negundo L. were used as bare-root dip treatment for the management of phytonematode, Meloidogyne incognita infecting tomato (Lycopersicon esculentum) and chilli (Capsicum annum) plants. Significant reduction was observed in the root-knot development caused by M. incognita on the experimental plants. Leaf extracts of Murraya caused relatively higher inhibition in root-knot development and nematode multiplication than Vitex. Improvement in plant growth was noted. The efficacy of root-dip treatment with respect to improvement in plant weight and reduction in disease incidence increased with the increase in concentration of leaf extracts and dip duration.
