A new foliar disease of dry bean, nematode angular leaf spot (NALS), is caused by Aphe-lenchoidea rizemabosi. The disease is typified by numerous dark, angular lesions on leaves and occasionally a superficial necrosis on the uppper surface of the petiole. Diagnosis of NALS is based on the presence of foliar symptoms and recovery of nematodes from symptomatic tissue. Infested fields were infrequent in a field survey of 7,175 ha in |
