Sumario:In onion's (Allium cepa L. c.v. Valenciana) crop at the end of the vegetative cycle, situated at the Department Cruz del Eje (Córdoba), we observed plants with apical clorotic spots that evolved to necrotic, finally covering all the affected leaves. Isolation and pathogenicity test demonstrated that Stemphylium botryosum Wall. was the causal agent. Also the sexual stage, Pleospora herbarum Pers., was observed.
