    Emerald Ash Borer

    “The carry-over of imidacloprid [IMA-jet] trunk injections with the Arborjet system gave about 63- 77% control in the second year following a single trunk injection in 2004, suggesting that an every-other year treatment may be possible.”

    “In 2003, we evaluated several insecticide products and application methods to assess their effectiveness in controlling emerald ash borer (EAB).”

    “Our objectives were to (1) evaluate registered insecticide products and application methods for adult and larval control; (2) identify optimal timing for soil, trunk and spray applications; (3) monitor persistence of insecticides over time; and (4) identify factors such as tree age or previous injury that could affect insecticide efficacy.”

    Hemlock Woolly Adelgid

    Arboriculture & Urban Forestry 2007. 33(1):12–21.
    “These results demonstrate that hemlock with high HWA pressure can be successfully treated using IMA-jet and the Arborjet Tree I.V. system.”

    Joseph J. Doccola, Peter M. Wild, Ilangovan Ramasamy, Paulina Castillo,and Christine Taylor

    Journal of Arboriculture 29(6): 327-330, November 2003

    “Injected trees had significantly (p < 0.05) lower HWA populations compared to untreated controls; mean mortality for injected trees was over twice that of noninjected trees.”

    “The Arborjet trunk injection treatments with imidacloprid [IMA-jet] provided a high level of control (92 to 100 percent), suggesting that they were efficacious against second-year as well as first-year larvae.”
