Nematicidal Activity of the Leaf Extract of Vinca rosea, Carbofuran and their Combinations against Meloidogyne incognita Infesting Papaya

The nematicidal efficacy of the leaf extract of Vinca rosea (250ppm) and carbofuran (7.5 ppm) alone, and their different combinations viz. 9: 1, 8: 2, 7: 3, 6: 4 and 5: 5 for the management of root-knot nematode, Meloidogyne incognita in vivo in papaya plant cv., Honey Dew in pots as well as micro plots is reported. V. rosea (250ppm) alone in pots and a 5: 5 combination of V. rosea (250ppm) and carbofuran (7.5 ppm) in micro plot were significantly effective in influencing the plant growth parameters as well as in reducing population density of root-knot nematode, M. incognita.
