Early blight (Alternaria solani) is a very common fungal disease of tomatoes and potatoes, and can infect a number of other crops as well.
A. solani is often referred to as ‘target spot’ because the infection lesion resembles the concentric-circle pattern of a target. Each lesion is about 1cm in diameter and all parts of the plant are vulnerable. Lesions on the fruit are more likely to begin near the stem end.
A. solani is a ‘necrotrophic pathogen’: it kills the host tissue using enzymes that eat into the cell wall, and feeds on the dead plant cells.
