Spots on Azaleas - Knowledgebase Question

Midlothian, VA
Question by mmkapil

We have recently moved into a new home that has many large azaleas surrounding it. I have noticed that most of the leaves are turning a pale color, almost white. On the bottom of the leaves are brown spots. I have not seen any mites or other insects on them. On the advise of a local nursery, I sprayed for mites, with no improvement. Some of these azaleas are very large, almost 5 feet in height and I would hate to lose them...Please help.

Based on your description it is possible they suffered from lace bugs this past spring and summer. These can be sprayed three times with insecticidal soap at weekly intervals beginning in mid spring when they become active. To be sure of the diagnosis, you might wish to take a sample to your County Extension (751-4401) for a more definite identification and the optimum timing for the spray in your area.
