Method: Incision-point application
The incision point application method, sometimes also referred to as “hack and squirt”, is a technique in which multiple incisions are made into the tree, and then herbicide is applied to each hack. This method allows for precise, calibrated treatments, meaning less herbicide is often needed compared to conventional control methods. No diluting or mixing is involved with this control technique, which minimizes the risk of accidental exposure and user error. This method causes trees (e.g., albizia) to lose their leaves over the course of a couple of weeks and eventually break apart over months. Some species, including African Tulip (Spathodea campanulata), take up to 180 days to entirely defoliate.
Incision-point application is most known for its usefulness in controlling albizia trees, but it also works on other woody invasives.
- Using a hatchet or machete, make incisions ‛hacks’ at a 45-degree angle into the sapwood
- At about waist high, make a hack every 2 inches around the trunk to make a circle.
- Apply .5 ml of undiluted herbicide into each hack.
Pesticide Safety
Always make sure to read the entire product label before mixing and applying pesticides. It will provide you with the information you need to safely and effectively use the product. Be sure to wear the appropriate personal protective equipment (PPE) as specified on the label, such as a long-sleeved shirt, long pants, close-toed shoes, chemical-resistant gloves, and protective eyewear. Store pesticides out of reach from children and pets in a garden shed or well-ventilated area. It is important to make sure that pesticides are never stored in cabinets with or near food, animal feed, or medical supplies.
