Intricate cascading roots on a Western Hemlock, Tsuga heterophylla.

Since I was the only one that was able to make it into work yesterday due to the snowstorm, I ended up getting stuck there for 20 hours doing different shifts. Between bouts of nearly falling asleep this was one of the things I did while manning the door of the tall building of residents that I work at, a piece of a newer YouTube Storytime Animator, Ringo Tsuga ^_^

Im curious to any forestry people out there that do field pathology what are you currently using to fight HWA and HES. and when do you treat?

mixed mesophytic forests and especially Hemlock forests are critical for cold microclimates in specific woodland and even are critical for many cold water riffle communities that support unique darters and brook lamprey. Many crawdads require different dissolved 02 requirements and colder water holds more 02 on average. A few different moth species and wasps are obligates, a few different birds are obligates, and many saprotrophs are duff obligates. Many birds mentioned in this video have Hemlock preferences. In my area sawett owls used to be known to visit hemlock stands in the Allegheny plat of Ohio and are much less common in their historic range as hemlocks and white pine forests decrease. I really want a code of ethics produced for specific usage of insecticides since imidicloprid seems to be the standard for fighting these.

I’ve been using a nonbasal drench as of late and a different type of neonic because It targets two species better than imidicloprid and is a target specific(systemic injection) that minimizes environmental impact when compared to these basal drenches that have more external longterm effects.

The product I’ve been using is called Dinocide which is a dbh adjusted self contained injectible systemic version of dinotefuran. I prefer this specific product over imicide because Im also after Hemlock Elongate Scale and I don’t think imidicloprid is the best translaminar despite having a longer 2 year residual.

I also like the practice of hort oil /mineral oil/ neem to suffocate eggs and crawlers in fall and early spring.

“Thank you for today.”

Is this really happening?

“Stay still. Tsuyu.”

“Ah. Was that alright?”

...

“It was perfect.”

I watched it and I have some thoughts about it.
