White Spots on Photinia (Red Tip) Hedge: Insect or Fungal?

White Spots on Photinia (Red Tip) Hedge: Insect or Fungal?

Photinia hedge losing leaves with white spots on foliage: test if spots rub off with liquid inside (scale insects) or are powdery (fungal).

Diagnosis & Treatment

• If spots rub off with liquid: Scale insects. Treat with malathion spray or Bayer Advanced soil drench (systemic, 1–2 weeks control, 1 year protection).
• If powdery, not rubbing off: Fungal leaf spot. Treat with Daconil (chlorothalonil) fungicide; repeat in 10 days.

Cultural Practices

• Prune for air circulation.
• Water at base, not foliage.
• Remove fallen leaves.

Photinia is prone to both issues; correct diagnosis ensures effective treatment.
