Click that part about signs and symptoms. Look for upper branches dying.
The latest and best is Tree-age solution. Superior results--lasts more than one year--needs professional injection.
For myself and homeowners, the Bayer Tree and Shrub is a good bet. Contains imidicloprid. Pour solution around base of the ash trees about when leaves reach full size in spring. It has worked at my daughter's house--so far... neighbors...not so lucky. We have lost thousands of ash trees around here.
