A pea disease caused by a Brazilian strain of tomato spotted wilt virus (TSWV), as identified through host range, serology, and electron microscopy is described. TSWV was found in pods and seed testae, in addition to stems and leaves. Symptoms were usually more severe in cv. Triofin than in ‘Mikado’, both of which occupy more than 95% of the total area planted to dry peas in Brazil. Seed transmission was not detected. So far, the virus has been found to occur in five states in Brazil, although disease incidence has generally been low.
