What causes brown spots on the leaves of my lilacs?

The leaves start out healthy and green, but now have lots of little brown spots, then turn yellow and fall off.

What causes brown spots on the leaves of my lilacs?
Your lilacs are suffering from Bacterial Blight (pseudomonas syringae). You'll need to spray your lilacs with a fungicide to control this damaging bacterial disease. The best on the market, one that I have used for over 20 yrs, is a product made by "Ortho" called "multi-purpose fungicide" which contains "Daconil" 2787. This fungicide controls over 130 different diseases on trees, shrub, and lawns. It can be easily purchased in the garden centers of Walmart, Home Depot, or Lowes. Follow the directions on the mixing rate which is easy to follow. This fungicide will only control any "further" infection and will "not" reverse the leaf spotting already done. Here is a link with the product info... Hope this answers your question.
