- 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.
- Chemical control: not a method for aphid control.
