The way this chemical works is by absorbtion into the root system of the tree roots. Drenching the soil with 5-10 gallons of diluted Dominion or more (depending on size of tree) and then topically spraying the tree trunk up to the first limbs helps to improve absorbtion.
Other than this, a local arborist can use a tree injection with chemicals only available to licensed professionals.
Hope this helps.
