The Sycamore tree in question has Sycamore Anthracnose. This is a common disease that also effects Ash, Maples and Oaks. It is a result of the wet, cool spring that occurred in Bloomington. The twig blight that is present is the classic sign of the disease. At this point there is nothing that can help the tree other than the return of dry hot weather to control the pathogen. Usually, around July 4th, a new flush of leaves push out and you can't tell the tree looked so bad this spring. The use of a fungicide and fertilization can be applied in the late winter to help prevent this from occurring in the future. Application now will do nothing.
