Does ASR affect any other crops grown in the United States?
Some common leguminous crop plants and weeds are also hosts, including yellow sweet clover (Melilotus officinalis), vetch (Vicia dasycarpa), medic (Medicago arborea), lupine (Lupinus hirsutus), green and kidney beans (Phaseolus vulgaris), and lima and butter beans (Phaseolus lunatus). Of most concern may be the snap bean (Phaseolus vulgaris) industry on Virginias Eastern Shore and in other parts of Virginia. Although the snap bean is listed as a host species of ASR, the snap bean is not as susceptible as the soybean. According to observations by researchers on snap beans and soybeans in South Africa, it is very difficult to find ASR in fields of snap beans, even when adjacent soybean fields are severely diseased. However, some snap bean cultivars are more susceptible than others. Corn and other grain crops, alfalfa, cotton, and peanuts are not hosts to ASR.
