- Bronze or reddish-brown discoloration: Infected leaves exhibit a distinct bronze or reddish-brown colour, particularly on the upper surface. This discoloration may appear as blotchy patches or cover the entire leaf surface.
- Leaf spots and lesions: Initially, small dark spots develop on the leaves, which gradually enlarge and merge to form irregular-shaped lesions. These lesions may have a tan or gray center surrounded by a darker border.
- Leaf distortion and necrosis: Infected leaves may become distorted, curled, or twisted. They may also develop necrotic areas, turning brown or black. The affected tissue may eventually die off.
- Premature leaf drop: As the disease progresses, infected leaves may prematurely drop from the plant. This can result in defoliation and an overall thinning of the plant canopy.
These signs collectively indicate the presence of bronze leaf disease in the affected plants. If you observe these symptoms, it is essential to take appropriate measures to manage the disease and prevent its spread to other plants.
