What is causing the leaves of my azaleas to look stippled and bleached-out?
Azalea lace bugs are found most often on the undersides of leaves. The adults are about 1/8 inch long with lace-like wings. They feed on the leaves, causing a blotched or stippled appearance on the upper leaf surface. Dark spots of excrement can be found on the undersides of the leaves. Infested leaves turn yellow and drop. Orthene and Malathion can be used to control severe infestations of lace bugs. Make the first application as soon as the young nymphs appear in the spring. A second application may be needed 7-10 days later. Thorough coverage of the leaves is essential, including the undersides.
