Where it grows
Richardia brasiliensis serves as a host for nematodes and bacteria that cause disease and damage to crops. Nematodes harbored in its roots cause dry rot in yams. In brassica fields, this plant hosts bacteria that cause black rot. As well as damaging pests, it can also host beneficial mites as a natural form of pest control.
Uses
