  • In India, where marigolds are traditionally planted among other crops, African marigolds (Tagetes erecta) intercropped with tomatoes or okra, were found to be effective for reducing six kinds of nematodes including the root knot nematode, and for increasing the quality and quantity of crop yields. 57 There appear to be several ways in which marigolds affect nematodes: substances exuded from marigold roots are nematocidal, the nematodesÂ’ life cycle is interrupted because nematode larvae have difficulty penetrating marigold roots, and nematodes are unable to develop once inside the roots.
