Bean Common Mosaic Virus

Casual Agent

Bean common mosaic virus (BCMV) is a Potyvirus that infects various bean species.

Symptoms

Symptoms include puckering, blistering, and foliar distortion. Downward curling and rolling may also be present. Plants infected early may end up stunted and distorted.

Disease Cycle

The virus is spread season to season through infected seeds, aphid vectors, mechanical transmission and, occasionally, pollen.

Management

• Source certified disease-free seed.
• Grow bean plants that are labeled resistant to the virus.
• Manage aphid populations on bean plants.
