Embark may be foliar also. I believe Mastiff and Snipper are injection. For injection you may be looking at 150 to 250.00 for large trees. Your timing must be perfect. I have never treated sweet gums so I cant help with more details. I can say that I am somewhat a fan of sweet gums.
It's not a bad looking tree, it's the litter. I slip on them, they get stuck in the belt pulleys, and make a huge mess to clean-up.
