Abstract:
Ginger leaf spot disease is one of the major fungal diseases of ginger. In the present study, the rate of growth of leaf spot (C. gloeosporioides) has been compared with different solid culture media types viz., Potato Dextrose Agar, Ginger Leaf Extract Agar, Czapek’s Dox Agar, Potato Carrot Agar, Richard’s Synthetic Agar etc. Among the various solid media tested, maximum mycelial growth was observed in Richard’s Synthetic Agar (90 mm), Potato Dextrose Agar (90 mm) followed by Czapek’s Dox Agar (89 mm) and lowest growth was observed in Potato Carrot agar (72.50 mm) at 27±1 °C. Colour of colony varied from grayish white to white. Texture of colony varied from velvety to cottony in nature, margin of colony varied regular to irregular and excellent sporulation was recorded in Potato Dextrose Agar and least sporulation was recorded in Czapeck’s Dox Agar and Oat Meal Agar.
