SGH Treatment Instructions

This 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:
Optimized Optimized Insecticide Dosage for Hemlock Woolly Adelgid Control in Hemlock Trees -- a detailed treatment recommendation developed in 2016 by Dr. Elizabeth Benton (Warnell School of Forestry and Natural Resources, University of Georgia, Tifton, GA) and Dr. Richard Cowles (The Connecticut Agricultural Experiment Station, Windsor, CT).  This new recommendation both reduces insecticide use for large trees and provides a precise dosage for any specific size of hemlock tree, based on the tree’s diameter at breast height (DBH), while still providing at least 5 years of protection following a single application.

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.

 

THE DETAILS:  If you ALREADY KNOW THE BASICS of treating hemlocks but need help with the details, select the appropriate one-page application document below.  To choose the right one:
Step 1.  Find the treatment product (Imidacloprid, Safari, etc.) and formulation (liquid, powder, etc.) you intend to use.
Step 2.  Then, under that product and formulation heading, select the application method (Kioritz soil injector, soil drench, etc.) you plan to use.

Note that these instructions are completely consistent with the product labeling but contain only the information specific to treating hemlocks.  If you have any questions, please call the Hemlock Help Line 706-429-8010.

   Wild by Law -- Film (54 min.) by Larry Hott, Diane Garey, Ken Chowder, Linda Hunt, Florentine Films., Direct Cinema Ltd. -- The story of the Wilderness Act of 1964 and the three men responsible for its passage: forester/philosopher Aldo Leopold, author of the bestselling A Sand County Almanac and the first to bring the word 'ecology' into standard usage; Bob Marshall, millionaire socialist and founder of the Wilderness Society; and Howard Zahniser, a tireless bureaucrat with a profound love of the wild places he seldom saw. Singly and together, these three fought against the current of American thought from the 1920s through the 1950s to attain what had once seemed an unimaginable victory. More than just the story of an historic struggle to preserve the natural world, Wild by law provides an invaluable overview of the roots of the environmental movement, offering a deeper understanding of one of the most important issues facing contemporary civilization.
