Indian Hawthorn Leaf Holes: Cercospora Leaf Spot Treatment

New Indian hawthorns show small holes in leaves preceded by brown spots (3/8–1/4 inch). Not Entomosporium leaf spot. Likely Cercospora leaf spot or similar fungal disease. Plants otherwise healthy.

Treatment Protocol

Apply Daconil (chlorothalonil) or similar ornamental fungicide every 7 days for 3 weeks. For organic option, try neem oil, though less reliable for persistent leaf spots. Practice strict sanitation: remove and destroy all fallen leaves (do not compost). Prune for air circulation, disinfecting tools with 10% bleach solution. Water only in morning, avoiding foliage wetness.

Expected Outcome

With consistent treatment and cultural practices, significant improvement should appear within weeks. Monitor new growth for reinfection.
