BONIDE (imidacloprid) Elm Application? [BORERS?]

PFE, What a shame with all that root zone damage on such a nice tree.

A few thoughts; The tree is now stressed, think about protecting against DED.

Chlorpyrifos treatments for Bark Beetles, prune out deadwood for sanitation.

Increase mulch bed, maintain soil moister & fertilize.

Good luck!

It is actually healthier this year after that backhoe then all previous years! The mulch bed is 4ft out on all sides a few inches thick with a layer of farm composted manure under the mulch bed.

I have started pruning out deadwood all over the tree, removed several hundred pounds of deadwood. I'm thinking it is already battling DED with all that flagging, I'm not licensed for injection unfortunately, but can probably piece the system together at a hardware store. Is Chlorpyrifos an injection or a systemic root drench?

Bark Beetle info...Native Elm Bark Beetle Control

Chlorpyrifos is a restricted use pesticide, not be available without license.

Your Drenching w/Merit should work check the label, I think you'll need a higher rate.

The mulch ring needs to be extended to drip edge, 4ft is not cutting it.

Going to try something different this year I picked up Garant 2F, I think we did it around this time last year however this is the first week we have had with temperatures above freezing so far.
