Q: I have circular spots on my Indian Hawthorn. What is it?


A: The cause of the spots on the leaves is a fungus called Rhizoctonia solani Kuhn. The leaf spots are tan with alternating light and dark concentric rings. The spores of this fungus are easily spread during warm, rainy weather. Good sanitary conditions are important such as removal of leaf litter and avoid overhead irrigation which increases the chance of spreading the disease. A fungicide will be required to eliminate the disease.
