Symptoms appear first on lower part of plant and move upwards
Initial symptoms are small circular or oval chlorotic spots on leaves which develop light to dark brown centers; as the lesions expand, they may develop concentric zones
Very small water-soaked spots between leaf veins which enlarge and turn dark brown to black
Severely infested leaves may dry out and curl then drop from the plant.
Stems may have elongated dark streaks.
Irrigate plants in the morning to allow plenty time for plants to dry out during the day; irrigate at base of plant to avoid leaf wetness
Use adequate plant spacings to decrease humidity in the plant canopy
Bacterial leaf spot is difficult to control; plant pathogen-free seed; avoid overhead irrigation; do not work with plants when they are wet
