Dogwood tree diseases

Asked July 7, 2017, 12:01 PM EDT

I have 3 Dogwood trees that have black spots on their leaves and on one branch the leaves are turning red and that particular branch is turning black. I have been using " Bonide" Fung-onil with no success. What can I use to stop this fungus and should I trim off that branch?
