It can infect beans and many other legumes. This disease is found worldwide. It was first described in Russia in 1894, and has been known in the US since 1917. This disease stunts, but rarely kills plants.
Symptoms vary by host, virus strain, and time of infection.
Leaves usually have an irregular mosaic pattern of light yellow and green areas, or a band of darker green color may follow the veins while the rest of the leaf remains green. Leaves may also be puckered or malformed, often with a downward cupping of the entire leaflet, or the leaflets may be narrower and longer than normal. Leaves may roll. Occasionally, bright yellow dots may be seen on the leaves. When the plants are infected early, they may be severely stunted and spindly.
