Only applied once so far but it seems to be working

This is what is recommended for the tar spot fungus in my maple trees but I couldn't find it at any retail store. It seems to have stopped the spread of the fungus but frankly the real test will be next spring which is supposed to be when it would have the most effect. It's easy to mix and apply with a sprayer but what I have read is to be sure to protect yourself when you spray. Remember, it IS a chemical that may be harmful.
