"To control susceptible woody plants...with stems less than 6 inches in diameter, mix 20 to 30 gallons of Remedy Ultra in enough oil to make 100 gallons of spray mixture. Apply with a backpack or knapsack sprayer using low pressure and a solid cone or flat fan nozzle. Spray the basal parts of brush and tree trunks to a height of 12 to 15 inches from the ground in a manner which thoroughly wets the lower stem, including the root collar area, but not to the point of runoff."

Overspray or spray drift of Remedy Ultra Herbicide can harm desired plants. While a light overspray won't be enough to kill a fully matured tree, it can certainly kill the leaves it has contacted. We recommend that you trim back the ivy and then treat the fresh cuts directly with the herbicide so that you are not spraying herbicide over the desirable tree.
