Rhododendron fulvum · Shrub
Bud blast: Remove and destroy infected buds promptly; avoid wetting foliage to reduce spore spread.
Powdery mildew: Improve air circulation and prune for light penetration; apply fungicide if severe.
Vine weevil: Use nematode treatments in soil during warm months or apply systemic insecticides.
Silver leaf: Cut out and burn infected branches well below the visible symptoms; avoid planting near infected trees.
Rhododendron leafhopper: Monitor for egg-laying damage to buds; control is often unnecessary as feeding rarely harms plant vigour.
