Worldwide distribution. Pasture and food legumes, e.g., yard long and French bean, and weeds, e.g., wild passion fruit. Important disease that lowers pod yields.
Plants stunted, leaves distorted with light and dark green patches. Spread by aphids, seed (>30%) and, less importantly, in pollen.
Cultural control: select healthy plants for seed; do not plant new crops next to old; interplant food legumes with maize; resistant varieties (in Africa mixtures of e.g., yard long bean varieties planted together); collect and burn trash after harvest.
