Abstract: Early blight is a dangerous disease affecting potatoes, primarily caused by Alternaria alternata and Alternaria solani in Western Europe. In Russia, it may also be caused by A. tomatophila, A. tenuissima, A. infectoria, and A. arborescens. A. grandis has been identified as the causative agent in Brazil. Different perspectives exist on the Alternaria species' significance in Early Blight, with some believing only A. solani is pathogenic, while others consider both species or a pathogen complex involving A. alternata and A. solani. Early blight symptoms include tiny, 1-2 mm black or brown lesions on leaves, concentric bands of dark pigmentation on stems, and "collar rot" on seedlings. Lesions can grow to significant sizes and infect both green and ripe tomato fruit. Potato tuber symptoms are irregular, sunken lesions, often encircled by a raised purple border.
Key words: tomatoes, fruit, alternaria, pathogenicity, potatoes, causative, complex.
