Control of plant parasitic nematodes by intercropping with Tagetes minuta

Resumen

Marigold, Tagetes minuta, in mix-culture, significantly inhibited the root-knot development caused by Meloidogyne incognita on tomato and eggplant and reduced the multiplication of Rotylenchulus reniformis and Tylenchorhynchus brassicae on tomato, eggplant, cabbage and cauliflower. The growth of all the test plants was improved when marigolds were present. The root-exudates of T. minuta also exhibited strong nematicidal action.
