Hack-and-squirt herbicide applications are one of the least expensive manual herbicide application methods. Hack-and-squirting root flares, in addition to the stems, during periods of active growth is effective with both glyphosate and imazapyr herbicides at preventing basal sprouting. Results and discussion: All hack-and-squirt treatments outside the spring sap-flow window, February to April, resulted in 100 percent top kill of red maple saplings and poles (Figure 3). Hack-and-squirt treatments control competition without impacting existing regeneration or desirable residual trees. They are effective at controlling trees 1 inch in diameter and greater. JavaScript seems to be disabled in your browser. Treated parent trees could be sold and harvested as merchantable timber, provided enough time is given for herbicide translocation (a minimum of 30 days). 3 For best results, treat trees 1.5 inches or more in diameter at chest height. Results and discussion: When applied in June or September the hack-and-squirt treatments controlled 100 percent of the striped maple stems (Figure 1). Black birch is effectively controlled with a 50 percent solution of a concentrated glyphosate herbicide. Stems less than 1 inch in diameter are too small to treat properly. Stem Injection Systems (Europe) Limited is the market leader and specialist in the provision of commercial weed control equipment and ancillary products. Figure 5.

Hack & squirt (or herbicide injection) involves introducing an herbicide into an ailanthus tree through spaced cuts made around the trunk of the tree with an ax, hatchet, or tree injector. Traditional understory treatments of beech and striped maple have used mechanized (skidder-mounted) mist blowers or a combination of mist blowers and basal bark applications. Step 4 Inject the herbicide … Arborjet trunk injection equipment injects formulations directly inside trees. The 50 percent Accord Concentrate (glyphosate) solution provided 100 percent control during February, June, August, and December. Researchers have concluded that species diversity declines as shade-tolerant reproduction continues to expand. Lance shaft contains four chambers into which shells are loaded. Shells are packaged 25 to a tube with 48 tubes contained in each 1200 shell box. Ez-Ject Herbicide System Ez-Ject Lance is the fastest, easiest way to selectively kill trees, stumps, and woody brush. Recognizing and treating less-desirable trees prior to a planned harvest increases the proportion of desirable species in the future stand. The large dropoff observed is likely explained by the large amount of herbicide required to control the parent tree. 72" hose and check valve included. The amount will vary depending on the size of the tree. Herbicide applications were made to frill cuts at the rate of one incision per inch (minimum of two incisions) of diameter measured at DBH. Trunk injection is the most effective alternative to spraying or soil applying pesticides for tree pest control. (53.8 percent glyphosate), Garlon 3A (44.4 percent triclopyr), and Polaris AC (53.1 percent imazapyr) applied using manual hack-and-squirt applications for controlling black birch with both dormant and growing-season applications. Dense understories of undesirable shade-tolerant trees interfere with the establishment and development of desirable regeneration such as northern red oak (Quercus rubra), white oak (Quercus alba), black cherry (Prunus serotina), and yellow poplar (Liriodendron tulipifera). Location: Central PennsylvaniaRange of red maple sizes: 0.7 to 5.8 inches DBHThree herbicide solutions: Results collected: September 2018Results and discussion: The results showed that once again 100 percent top kill is achieved on red maple using hack-and-squirt treatments applied July through November (results not shown). The most effective method for deadening undesirable standing trees involves using an herbicide. Tygon® herbicide hose for maximum chemical resistance. Striking the tree creates necessary force to deposit the pre-set amount of herbicide (slightly more than 1 ml). Make one injection per inch of tree dbh. Frill cuts are approximately 2 inches long and spaced 1 to 2 inches apart. The 5 percent solution of Polaris AC (53.1 percent imazapyr) provided sufficient control (83 to 93 percent) (Table 2). Photo by David Jackson. The method that we use most for infusing chemicals into trees is the Quickjet injector or the Quickjet Air injector. Herbicide applications were made to frill cuts at the rate of one incision per inch (minimum of two incisions) of diameter measured at DBH. Hack-and-squirt applications are target-specific treatments generally used to control trees that are 1 inch in diameter and greater. Restricting treatments to tree species different from desirable crop trees will minimize this concern. Striped maple top kill percent.Figure 2. All plots were evaluated 12 months after treatment. The chemicals then move into and through the tree mainly in the xylem sap. This is only a concern if you are using bark injection to thin desirable species, such as oaks, according to Jim. Applications made to undesirable trees facilitate the regeneration or growth of desirable trees in mixed-species standsâfor example, oak/hickory or cherry/maple. Material was sprayed into each frill cut until full. Black birch control percent.Figure 6.
