Ginger in Danger

Tip for farmers: caterpillars fear the sound of bee wings

Ginger has been extensively cultivated for use as a spice and traditional medicine. A study has confirmed that the pathogen Aspergilus niger causes necrotic leaf spot disease. This is the first report ever of the pathogen afflicting ginger. During a survey in Maharashtra in September last year, it was found that ginger leaves suffered from the disease. Symptoms appeared as small, rectangular to irregular, yellow spots on the leaves that covered a major area of the leaf when severe. The infection caused defoliation.
