Tree Injection Best Practices

How to utilize it as a tool for managing pests in the urban ecosystem

Summary: In this course, we will see how science has led to effective treatment of various insects and diseases based on tree size, health, and species as reliable predictors at preventing tree loss. We will explore Tree Injection Best Management Practices as compiled by co-authors Dr. Smiley and Shawn Bernick within the ISA’s Best Management Practice booklet. Developing a consistent training program of where to properly inject trees and approaching this application method as a toolbox approach. Learn the latest in trunk injection processes that minimize wounding while effectively managing pests and diseases, with the latest in open-system, trunk injection tools. We will cover the key distinctions between macro and micro infusion and why they are important to successful treatments.
