Professional Dual-Reservoir Tree Injection System

The Mauget Tree Defendr® Double Kit is built for arborists and plant health care professionals who demand efficiency, durability, and consistent vascular delivery in the field. Featuring dual reservoirs and eight brass injection ports, this system increases trunk coverage and reduces setup time on large diameter trees and high-production treatment programs. Operating within the optimal 15 to 25 psi range, it works with the tree’s natural transpiration process to promote controlled systemic uptake without drift or runoff. Reusable, serviceable, and manufactured in the USA, the Tree Defendr Double Kit is engineered to perform season after season.
