Abstract
Soybean (Glycine max L.) is widely cultivated in northeastern Italy, especially in Friuli-Venezia Giulia and Veneto. Since 2013, during early seedling development, necrotic lesions have appeared on upper leaves, spreading downward and causing up to 25% defoliation in the field. Purplish discoloration was observed on petioles, stems, and pods. Seeds showed pale to dark purple blotches on the seed coat, from small spots to full coverage. These symptoms are typical of Cercospora leaf blight (CLB) and Purple Seed Stain (PSS).
