Wanted to reach out and see what kind of results you all see with imidicloprid drenches and leafminer control; particularly arborvitae LM. It’s on the label, and my research says it’s effective, but the company I work for does not believe in it based on in-house research. Yet at the same time they are extremely paranoid about chemical trespass. So it’s frustrating to not have that tool “approved” when 90% of the arbs we treat are on property lines where we can only spray one side anyway.

I also find that the foliar applications line up with many birds nesting season and Thuja is a popular habitat choice.

For the most part not a significant pest to worry about IMO. But we do run into some arbs that get pretty fried from them.

good point about the mites.
