Garlon 4 Ultra Herbicide is not labeled specifically for use with a hack and squirt method for tree control, but typically this is an effective application using triclopyr herbicides. Keep in mind that taller trees will still need to be cut and removed safely, so you would normally cut these trees and then treat the fresh cuts with the Garlon 4 diluted at 20-30 gallons in enough oil to make 100 gallons of solution. This breaks down to 25-38 oz of Garlon 4 per gallon of oil solution.
