Yeah I prefer using proper nomenclature as well but that issue was put together under a time crunch.
Interesting about the differences between the different arbs. Western get wintern burn something fierce here and are becoming more common of late whereas the eastern is old hat but usually perform well.
We'll make a point to cover cottony maple scale as it has been known to flair up on occasion here. Scales in general are on an upswing here and I'm expecting predator and parasite populations to start building back up to help the cause. Consider some well timed IGR applications rather than the conventional insecticides. One suggestion that comes to mind is the use of dinotefuron. It's root soak/injection residual is only about 60 days so look at when applications were made. If they were too early before crawler emergence, that may be your problem. I would also recommend using a pretty strong rate though at $7 an ounce, it is expensive.
