injections for Hemlock Wooly Adelgid

[Tucker943]

First off, I have no experience with injection capsules. I have a customer with several young hemlocks with hwa. Im planning on treating them with Imicide. I have my trunk measurements and a material list. However, Mauget's website says to use an 11/64 drill bit, except in conifers. I'm waiting for a call back from the tech specialist at the company, to find out what I'm suspposed to use. What have any of you used? Have any of you treated hwa without spraying?

Got my answer from Mauget.

And it is...?

Drill deeper then 1/4 inch under the bark. Sink it in a few inches and use and 3/8s bit.

The area of best uptake is deeper into the tree, and because of the softer, spongier wood, an oversized bit will yield a hole of the correct size when all is said and done.

good luck and take notes. I am curious as to the outcome of this. I know that bug has devastated the Eastern Hemlock terribly.
