This tree injection system provides foresters, utility managers, and agricultural producers an efficient, effective, and economical way to control unwanted woody vegetation. Each study site was evaluated one year following treatment. Two treatments, Rodeo 4" and Polaris AC 10", controlled no stems greater than 1 inch in diameter. Treatments are effective when injections are made every 2 to 6 inches around the tree. Treatments are most effective June 1 to November 1 and when stems are not frozen. Some species, particularly maples, are prone to basal sprouting following hack-and-squirt treatments with glyphosate herbicides. Injections are made waist high on the tree. Black birch control percent.Figure 6. Prepared by David R. Jackson, forest resources educator, and James C. Finley, professor emeritus of forest resources. Stems less than 1 inch in diameter are too small to treat properly. Spring and fall sap flows are especially prevalent in black birch. Principle benefits of the herbicide tree injector, 1–Suitable for use where spray application not appropriate. Basal sprouting was highest for applications made during spring sap flow. Whether you have an invasive species or simply don’t like a tree variety, there are ways to kill it. You must have JavaScript enabled in your browser to utilize the functionality of this website. Control trees along drainage areas, roadsides, and utility right-of-ways. Caution: Herbicides can potentially kill or injure nearby trees through root grafts. They are used to apply either liquid or pellet herbicides to trees … 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. Trade names are used to give specific information. For tree and shrub pesticide and fertilizer applications under the soil surface, The fastest, easiest way to selectively kill trees, stumps, woody brush. This tool was developed by Arborjet and we had the privilege of doing some of the testing of the prototype. Figure 6. Herbicide Backpack Tree Injector Specifically developed for use in rough and sensitive environmental situations. The number of root sprouts controlled by hack-and-squirting parent beech trees with herbicides containing the active ingredients glyphosate and imazapyr is significant. Basal sprouting remained consistent throughout the remainder of the year for all herbicides studied, ranging from 10 to 50 percent. unit and QUIK-jet device with bottle top assembly. It provides a flexible tool landowners and managers can use to accomplish a variety of vegetation management objectives over a wide range of forest types. With the exception of Polaris AC and Polaris AC/Accord Concentrate solutions applied in June (Figure 4), basal sprouting was observed at some level for all other herbicide active ingredients and treatment months. Additional incisions made to root flares are effective at preventing basal sprouting in difficult-to-control species, like red maple. The spear is thrust into the tree at an angle of 30° to 40° from the vertical, opening a cut in the tree and applying the appropriate herbicide amount. Location: Central West VirginiaAverage diameter: 1.8 inches DBHFour herbicide solutions: Time of year: Two applications—September 2004 and June 2005Results collected: September 2005 and June 2006. When hard freezes are forecasted to occur at night following application, add RV antifreeze (propylene glycol) to the spray solution according to label directions. Ready for your large and small dose tree injection jobs. Get notified when we have news, courses, or events of interest to you. 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. Striped maple top kill percent.Figure 2. Hack-and-squirt herbicide applications are effective at any time of the year, except during heavy spring sap flow or severe drought. Herbicides are a versatile tool for manipulating tree species composition. In areas with high deer browse impact this may not be a concern as sprouts will likely experience heavy browsing. Arborjet Tree-Age G-4 Injectable Insecticide 1 qt. The Chemjet Tree Injector is an inexpensive reloadable syringe used to inject pesticides, fungicides and fertilizers to treat diseases and pests, to prevent death of the tree. Photo by David Jackson. Trunk injection is the most effective alternative to spraying or soil applying pesticides for tree pest control. If basal sprouting is unacceptable, only a very small window is available for treatment. The chemicals then move into and through the tree mainly in the xylem sap. The objective was to determine the effectiveness of glyphosate as Rodeo (53.8 percent) and imazapyr as Polaris AC (53.1 per-cent) using manual hack-and-squirt applications for controlling American beech root suckers. This section shares information from studies conducted by Penn State and the U.S. Forest Service. They are effective at controlling trees 1 inch in diameter and greater. In addition, preferential browsing by white-tailed deer favors less-desirable shade-tolerant tree species such as striped maple (Acer pensylvanicum), American beech, and eastern hophornbeam (Ostrya virginiana). We are using this method for almost all of our injections now. It allows the owner to favor species better suited to the site that meet future desired conditions and their objectives. A large drop in the number of root suckers controlled was observed in the larger size classes (Table 3). Hack-and-squirt herbicide applications offer one of the safest, most efficient, target-specific, and least expensive means of eliminating unwanted tree species. (2004) where about half of the existing beech sprouts less than 1 inch DBH and approximately 22 percent of the sprouts 1 to 5.9 inches DBH were controlled by hack-and-squirting all parent beech trees 6 inches in diameter and larger with a 50 percent solution of Accord (41.5 percent glyphosate). A small quantity of herbicide … Control trees along drainage areas, roadsides, and utility right-of-ways. Leave intact bark between cuts to facilitate herbicide translocation to roots. Basal sprouts on top-killed red maple treated with a glyphosate herbicide. Spacing between cut edges should not exceed 1-1/2". The chosen treatment diameter depends on stand characteristics. “Root grafts are usually species-to-species,” he said. Photo by Dave Jackson.
