Bacterial canker

Initial symptoms are the result of primary, systemic infection and first affect the lower leaves causing leaf curling, wilting, chlorosis, and shriveling. Plants infected from seed may die, fail to set fruit, or show no symptoms. In advanced stages, the pathogen spreads throughout the plant and causes poor growth, wilt, and plant death. Foliage throughout the canopy wilts, yellows, turns brown, and collapses. Stems can split resulting in open breaks or cankers and stems break easily. Secondary infections occur from rain splashing onto foliage, stems, and fruit. Spots occur on green fruit and are very characteristic: white to yellow spots, 3-4 mm with raised brown centers (“bird’s eye spots”). If infected plants are present, the movement of bacteria from one plant to another during normal watering, handling, and ventilating activities occurs readily. Primary, systemic infections may not cause symptoms until the plants begin to flower. Plants begin to wilt starting from the lower leaves and progressing upward. Early symptoms include one-sided wilting of leaves and downward cupping of leaves. Later, stems may develop adventitious roots, external brown streaks, or may split open revealing internal discoloration of vascular tissue. The discoloration is yellowish to brown at first but becomes dark reddish brown and eventually the stem pith also becomes discolored and rotten.
