Managing Entomosporium Leaf Spot on Red Tip Photinia

Red tip photinia in Southeast Texas develops rust-colored spots and defoliates. Local nurseries stop selling it due to this chronic fungal disease (Entomosporium leaf spot).

Control Program

Spray every 2 weeks during growing season.
Use propiconazole—excellent systemic fungicide.
Consistency is key; miss a treatment and disease rebounds.

High maintenance, but manageable if you commit to the schedule.
