Woody Ornamentals
Rhododendron
If the younger leaves are still healthy, no control is needed.
Older leaves have numerous fungi that attack them once they get
old. Often these fungi cause spots in the leaf. When these spots
die and fall out they leave holes. The fungi will not attack the
younger leaves.
