Water extracts of neem cake (the residue remaining after the oil has been pressed out of the seeds) are also nematocidal.
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 nematodes life cycle is interrupted because nematode larvae have difficulty penetrating marigold roots, and nematodes are unable to develop once inside the roots.
