Symptoms of bean common mosaic virus (BCMV) are cupping and twisting of leaves with a light and dark green mosaic pattern. The dark green tissue is often bubbled and/or in bands next to the veins. Affected plants produce smaller, curled pods with a greasy appearance, and yields are reduced. The virus is seed borne. It can be transmitted by several aphid species.What to do:
- Use certified and disease-free seeds
- Plant resistant varieties (e.g. French bean variety ‘Paulista’)
- Control attacks of aphids
- Remove infected plants from the field
