What kind of fungicide was this? Sulfur fungicides tend to be a little less damaging to some trees and shrubs. Copper fungicides can kill trees if applied to heavily.

If this is an area where water naturally runs to, then it could have been over concentrated in that area. Why was the fungicide applied to the lawn? Did you see signs of infection? Applying copper fungicides for preventative maintenance is not recommended.
