Tomato Diseases
Early blight and septoria are two leaf-spot diseases that affect the leaves, stems and fruit of tomato plants. Plants can be infected with both at the same time.
SEPTORIA
■ Small leaf spots
(less than 1/8 inch in diameter)
■ Disease spreads upward from oldest to youngest growth.
■ Spots have a dark edge and a tan or gray center
■ Most common in highhumidity conditions
EARLY BLIGHT
■ Disease infects leaves, stems and fruit
■ Disease spreads upward from oldest to youngest growth.
■ Black, leathery spots on fruit often surrounded by yellow tissue
■ Sunken dark, round stem lesions form with concentric circles inside
■ Occurs in warm, wet weather conditions
