Ekka, I'm the wrong guy to ask about borers, because in my area they are all wimpy and easily treatable with soil applied insecticides like Imidiclorpid.
These new exotics beetles aren't around me yet, like the EAB and Asian Longhorned Beetle.
We just got a gift from the south, Oak Borers ( a diffrerent longhorned beetle), because of warming trends, but haven't gotten to treatment protocols yet. Common sense will prevail, I suspect. Use tree biology and entomology to understand what is the best approach.
Soil applied Merit takes time too move, borers kill fast. It's easy to understand why trunk injection methods have higher efficacy with these fast moving beetles. If you see Ash trees dying up the road, soil inject today, don't wait until your trees are turning yellow!
More profoundly, plant some new trees, not Ash. You can't keep this pesticide protocol up forever. If you live in the US or Canada, don't plant an Ash, duh!
Say you have a nursery, cross out he order for a thousand Ash trees.
Get it?
