Note that this is a large file and may take a few minutes to download. A free digital version of the presentation is available upon request through the Hemlock Help Line 706-429-8010, or click for the Clinic Presentation Notes. ■ Hemlock Help Program Description (updated 4/9/20) -- Planning document including problem statement, program goals and objectives, guiding principles, scope, and services of the Hemlock Help Program. ■ How SGH Uses Your Donations (updated 2/9/19) -- A recap of our guiding principles and examples of the educational and service activities supported by your donations.

SGH Treatment InstructionsThis section is organized in three parts: ■ Getting Started -- for people who are new to the treatment process. ■ The Details -- for people who know the basics but need the details for the particular product, formulation, and application method they plan to use. ■ Ultimate Short-Cut Instructions -- for people who are experienced in the treatment process and just need a quick reference card or sheet to take to the treatment site.
Also see: GETTING STARTED: If you're NEW to the treatment process, it would be wise to start with the "Introduction to Treating Hemlocks." Once you've mastered the basics, then proceed to The Details below. Note: If you plan to use a soil injector to treat your trees, please read "Testing & Adjusting Injector Calibration" for the particular device to ensure that it's working properly before you load treatment mixture into it. ■ Introduction to Treating Hemlocks (updated 8/8/20) -- Complete step-by-step description for assessing the level of HWA infestation, choosing and measuring the trees to be treated, choosing the appropriate treatment product and method of application, estimating the amount and cost of chemical, obtaining the application device and tools, applying the treatment, safety guidelines, and cleanup procedures. ■ Chemicals, Contacts and Sources (updated 2/25/21) -- Consolidated reference sheet containing names of generic treatment products, contact information for places to purchase them, places for borrowing soil injectors, qualified hemlock treatment professionals, and sources for hemlock saplings. ■ CHEMICAL CALCULATOR (updated 9/9/20) -- This tool can be used to estimate the amount and cost of chemical needed for a hemlock treatment project. After the Instructions tab, it contains sheets for Imidacloprid 75 WSP, Imidacloprid 2F/2L, Imidacloprid CoreTect, Safari 20 SG, and a few other chemicals/formulations. A new Summary page has been added as the last tab containing a chart of the DIY cost to treat individual trees in each size range with each chemical. It is an Excel spreadsheet that you should download to your own computer instead of trying to use it on line. ■ EZ-Ject Soil Injector Care & Use Card (updated 12/8/20) -- Quick reference card for anyone who owns, lends, or borrows an EZ-Ject soil injector; laid out 4 to a page for double-sided printing. It can be laminated and attached to a soil injector. ■ EZ-Ject Soil Injector Maintenance-Testing-Adjusting Calibration (updated 3/6/21) -- Easy to follow instructions for determining whether an EZ-Ject injector is pumping out the correct amount of liquid per pump. For the model that dispenses a standard 1/2 ounce per pump, the output should be 6 ounces for 12 pumps of the handle. For the model that dispenses a standard 1/4 ounce per pump, the output should be 3 ounces for 12 pumps of the handle. If calibration testing indicates that the unit is pumping out less than it should, there is no way to mechanically adjust the calibration. Instead, use the Alternate Mixing Instructions included in this document to adjust the mixing ratio to achieve the correct amount of active ingredient per ounce of output. ■ Kioritz Soil Injector Care & Use Card (updated 6/12/19) -- Quick reference card for anyone who owns, lends, or borrows a Kioritz soil injector; laid out 4 to a page for double-sided printing. It can be laminated and attached to a soil injector. ■ Kioritz Soil Injector Maintenance-Testing-Adjusting Calibration (updated 3/10/21) -- Easy to follow instructions for determining whether a Kioritz injector is dispensing the correct amount of liquid per pump. When the calibration ring in set on 5 ml per pump (i.e., the calibration ring is screwed down as far as possible toward the tank), the unit dispenses 1/6 ounce per pump so the output should be 2 ounces for 12 pumps of the handle. If calibration testing indicates that the unit is pumping out less than it should, use the Alternate Mixing Instructions included in Attachment A of this document to adjust the mixing ratio to achieve the correct concentration of active ingredient per ounce of output. Attachment B of this document contains diagrams and part numbers which may be useful in discussing function or malfunction and possible repair with the Hemlock Help Line. ■ Nu-Arbor 1-Two Root Injector Testing-Adjusting Calibration (updated 9/24/20) -- Easy to follow instructions for determining whether a Nu-Arbor injector is pumping out the correct amount of liquid per pump. The unit is designed to dispense a standard 1/4 ounce per pump, so the output should be 3 ounces for 12 pumps of the handle. If calibration testing indicates that the unit is pumping out less than it should, there is no way to mechanically adjust the calibration. Instead, use the Alternate Mixing Instructions included in this document to adjust the mixing ratio to achieve the correct concentration of active ingredient per ounce of output.
