The Mauget Tree Defendr® Single Kit is a professional trunk injection system engineered for arborists, plant health care (PHC) professionals, municipalities, and serious tree care operators who need reliable, repeatable vascular delivery.
Designed for performance under real field conditions, Tree Defendr delivers nutrients, plant growth regulators, fungicides, and insecticides directly into a tree’s vascular tissue for precise systemic uptake. By working with the tree’s natural transpiration process, the system operates efficiently at approximately 15 to 25 psi, supporting controlled absorption without drift or runoff.
Durability and serviceability were priorities in the design. Major components are reusable, field-repairable, and easy to clean. The linear manifold design feeds four machined brass feeder tubes, helping you efficiently treat larger diameter trunks while reducing clogging and maintaining consistent flow.
Compact, straightforward, and built for repeated production use, the Tree Defendr is manufactured in the U.S.A. and backed by a 1-year warranty.
