Cardamom (Elettaria cardamomum)
Chenthal disease ( Corynebacterium sp. and Colletotrichum gloeosporioides )
Symptoms
- Characterized by the appearance of rectangular linear reddish brown lesions mainly on the lower surface of the leaves.
- The lesions are clearly visible even on dried leaves.
- The incidence of the disease appears to be more severe in areas, which do not have proper shade.
- Even though Corynebacterium and Colletotrichum gloeosporioides have been isolated from the infected leaves, the pathogenicity of these organisms could not be established.
Management
- Providing adequate shade is the only measure recommended
