Intercropping for the management of root-knot nematode, Meloidogyne incognita in vegetable-based cropping systems

Efficacy of different intercrops, marigold, mustard and sweet potato against root-knot nematode, Meloidogyne incognita infesting vegetables like tomato, okra and brinjal were evaluated by growing intercrops in vegetable-based cropping systems. Among the different intercrops evaluated, marigold intercropped with different vegetables reduced the nematode population in soil, number of galls, egg masses per root system, number of eggs per egg mass and root-knot index as compared to growing of vegetables alone continuously.
