Identification Symptoms
- The disease is noticed on
leaves, leaf stalks, stems, twigs, branches and fruits, initially
producing water soaked lesions, later turning into typical canker.
- On leaves, water soaked
irregular satellite to angular raised lesions measuring 1-4 mm in diameter
are formed. These lesions are light yellow in colour, initially with
yellow halo but with age enlarge or coalesce to form irregular necrotic
cankerous patches with dark brown colour.
- On fruits, water-soaked, dark
brown to black coloured lesions are observed which gradually developed
into cankerous, raised or flat spots. These spots grow bigger usually up
to 1 to 5 mm in diameter, which covers / almost the whole fruit.
- These spots often, burst
extruding gummy substances containing highly contagious bacterial cells.
