Answer: Hi Susan,
Petal blight on azaleas must be treated before the buds open(as soon as colour is seen) with a fungicide such as mancozeb. All dead and diseased flowers must be collected and destroyed to prevent the spread of the spores by wind and water.

The azalea lace bug can be treated with a Confidor spray when they are first seen. The other option is to use the new Confidor Tablets which are inserted around the root area. The insecticide is taken in by the roots and trans located throughout the plant giving a more residual control. As the weather warms up and the azaleas are putting out new growth the incidence of lace bugs will increase. To monitor hold a piece of paper under the azalea leaves and gently tap the leaves. The tiny lace bug will fall onto the paper.
