The Mauget Tree Defendr® Double Kit is a professional dual-reservoir trunk injection system designed for arborists and plant health care (PHC) professionals managing high-production treatment programs. With two bottle assemblies operating from a single system, this kit increases efficiency on large diameter trees and multi-treatment jobs.
Engineered for dependable vascular delivery, the Tree Defendr system introduces nutrients, plant growth regulators, fungicides, and insecticides directly into a tree’s vascular tissue for precise systemic uptake. Operating efficiently at approximately 15 to 25 psi, the system works with the tree’s natural transpiration process to support consistent absorption without drift or runoff.
The linear manifold design feeds eight machined brass feeder tubes, allowing arborists to reach around large trunks efficiently while maintaining consistent flow. Larger diameter injector tubes help reduce clogging, and high-quality valves promote reliable pressurization in the field.
Built for durability, all major components are reusable, serviceable, and easy to clean. Designed for repeated field use, the Double Kit is manufactured in the U.S.A. and backed by a 1-year warranty.
