Abstract:

A Alternaria leaf spot (ALS) and flower heads spot (FHS) disease of Heliconia rostrata plants is prevalent in India. Heliconias plants are known for their beautiful, brilliant colorful flowering bracts. Breathtaking and unusual flower heads (bracts) rise from clumps of banana like leaves, sometimes very large or slender. They are also known as the birds of paradise which are found mostly in Indian gardens. Symptomatic can be seen on the leaves and flower heads like to be small and circular spots with concentric rings at first which later became irregular lesions. These circular spots were dark black coloured along the margins which encircled the necrotic region. With the spread of disease, these necrotic spots turned to appear as blight. Purified fungal suspension (1 x105 cfu/ml) was sprayed on healthy plants for the confirmation of pathogenicity test. Koch’s Postulates were established. This fungus was identified as Alternaria alternata and is the first report of ‘leaf spot and flower heads spot disease’ on this host from India.
