Phaseolus lathyroides is usually infected by cowpea mosaic virus (CMV) in fields of western Puerto Rico. Symptoms of infection by the virus are usually masked by symptoms of bean golden mosaic infections. CMV was detected in bean (Phaseolus vulgaris) fields where infected P. lathyroides plants were commonly found. Characteristics of the virus were similar to those reported by other investigators.
