Photinia Leaf Spot: Fungal Disease Requiring Ongoing Management

Photinia Leaf Spot: Fungal Disease Requiring Ongoing Management

13–15-year-old red tip photinia with spotted leaves dropping rapidly: Entomosporium leaf spot (fungus). Spots have tan centers, purple margins. Disease has removed photinias from many landscapes.

Management Program (Lifelong)

1. Prune back severely; remove all debris under plant.
2. Apply fungicide (Daconil or triforine) every 10–14 days during growing season.
3. Start at spring bud break for best results.
4. Water at base; never overhead.

Reality

High maintenance; many replace with resistant shrubs. But with diligence, photinia can be kept attractive.
