Identification Symptoms
- Alga infects immature guava leaves during early spring flush.
- Minute, shallow brown velvety lesions appear on leaves specialy on
leaf tips, margins or areas near the mid vein and as the disease
progresses, the lesions enlarge to 2-3 mm in diameter.
- On leaves the spots may vary form specks to big patches which may
be crowded or scattered.
- On immature fruits the lesions are nearly black. As fruits enlarge,
lesions get sunken and get cracked frequently on older blemishes as a
result of enlargement of fruits, lesions are usually smaller than leaf
spots. They are darkish green to brown or black to colour
