ArborSystems has made improvements to their Wedgle Direct-Inject Tree Treatment System, reportedly the only trunk injection application method that does not require a drilled hole as highlighted in the Integrated Pest Management (IPM) of Midwest Landscapes manual.
• Uses a needle-like injection tip that is pushed through the bark; the company says arborists and consumers should avoid using other trunk injection methods that involve drilling holes in the tree as part of the application process as that can permanently damage a tree's ability to move and store water and other nutrients
• Delivers chemicals directly inside the tree at a known dose rate with virtually no environmental exposure
• All of the hardware components are now made in the United States
