إنجليزي. An onion mycosis caused by Stemphylium vesicarium (Wallr.) Simmons was first observed in 1983. A survey of this fungal disease, achieved until now, showed its occurrence, causing important losses in seed production fields of the center and south of our country. Disease symptomatology, anamorf diagnosis and results of preliminery fungicidal tests are presented. We must conclude, that mancozed and iprodione, either alone or mixed, showed better efficacy than a copper oxychloride formulation
