Mauget Tree Defendr® Tree Injection Kits

The Mauget Tree Defendr® collection includes professional trunk injection systems engineered for arborists and plant health care professionals who demand precise, systemic delivery. Designed for efficiency and durability in the field, these tree injection kits introduce fungicides, insecticides, nutrients, and plant growth regulators directly into a tree’s vascular tissue for controlled uptake and reduced off-target exposure.

Available in both Single and Double Kit configurations, Tree Defendr systems are built to support everything from routine plant health care programs to high-production municipal and commercial treatment schedules. Operating within an optimal pressure range of approximately 15 to 25 psi, the system works with the tree’s natural transpiration process to promote consistent absorption.

Each kit features reusable components, machined brass feeder tubes, linear manifold design, and field-serviceable parts to minimize downtime. Whether you are expanding into trunk injection services or scaling an established PHC program, the Mauget Tree Defendr® kits deliver professional-grade performance, durability, and reliability season after season.

Manufactured in the USA and backed by a 1-year warranty, these trunk injection systems are built to meet the demands of modern arboriculture.
