Tomato Blight: How to Identify and Treat Early Blight in Tomatoes Tomato blight, in its different forms, is a disease that attacks a plant’s foliage, stems, and even fruit. Early blight (one form of tomato blight) is caused by a fungus, Alternaria solani, which over-winters in the soil and infected plants. Affected plants underproduce. Leaves may drop, leaving fruit open to sunscald. Early blight’s Latin name is sometimes confused with a form of tomato rot, alternaria, a different tomato problem altogether.

- Septoria leaf spot is caused by a fungus, Septoria lycopersici. It is one of the most destructive diseases of tomato foliage and is particularly severe in areas where wet, humid weather persists for extended periods. Septoria leaf spot usually appears on the lower leaves after the first fruit sets. Spots are circular, about 1/16 to 1/4 inch in diameter with dark brown margins and tan to gray centers with small black fruiting structures. Characteristically, there are many spots per leaf.

How to Prevent Late Blight on Tomatoes Septoria leaf spot: Symptoms of this disease usually first appear on the oldest leaves, after fruit start to ripen. Drought stress: This physiological injury can be distinguished from late blight by the lack of the fuzzy, spore-producing growth and the lack of stem lesions.Late blight, a disease that strikes tomatoes and potatoes, can quickly ruin an entire crop — and provide a source of infection for other plants.revent overwintering: Fortunately, the fungus that causes late blight needs living tissue to survive over the winter, so it can't overwinter on tomato cages or supports. However, infected potatoes (the other plant that gets late blight) can carry the disease through the winter.

Tomato Diseases The fungus survives on infected debris in the soil, on seed, on volunteer tomato plants and other solanaceous hosts, such as Irish potato, eggplant, and black nightshade. Prevention & Treatment: Use resistant or tolerant tomato cultivars. Use pathogen-free seed and do not set diseased plants in the field.
