A Practitioner’s Guide for Testing Herbicide Efficacy With the Incision Point Application (IPA) Technique on Invasive Woody Plant Species

The Incision Point Application (IPA) method is a refinement of the more traditional "frill cut" or "hack-n-squirt" basal application methods that minimizes the cutting action to small incisions around the base of the tree. It also precisely delivers known (micro) amounts of herbicide to each incision. This basic guide is for practitioners to conduct their own experiments, testing registered, non-restricted herbicides using the Incision Point Application (IPA) technique on invasive woody species of interest.
