ArborSystems Wedgle Direct-Inject Tree Injection System is effective anytime the tree is actively growing as the product is translocated with the sap. ArborSystems Boxer Insecticide-Miticide used with the Wedgle gives you two-year control of EAB and can be applied until six weeks before the first frost. And just a reminder, you can treat trees all day long and our trunk injection is a no drilling method so no power is required. Unlike other treatment methods that have to be done in the spring and mixed in the field, Wedgle is advanced technology for tree treatment. For more information, click here.
