The center of the spot may become tan and flecked with small black specks and, in wet conditions, may produce a mass of slimy salmon- colored spores. Leaf spots are small, circular, and brown. Yellow rings often surround them. The root system may be damaged so severely that the plant can be easily pulled. This disease affects ripe fruit only, causing almost perfectly round sunken spots with dark centers.
Early blight has different symptoms.
Early blight fruit spots are dark and have a target appearance. They are usually near the stem. They can be found on green fruit. Use disease-free seed. Resistant varieties are available and should be used whenever possible.
