I have 5 large Azaleas about 15 years old that have a heavy infestion of lace bug eggs on the underside of leaves. They have discolored the plant to a tanish color. I did treat these azaleas with Talstar at the begining of the season. Three applications in spring and summer. Now it is Novemeber in Zone 6 and I am concerned on these plants living. What should I do? Also what should I tell the customer, since I have been treating them for one season now.
