Good Afternoon,
I have a customer that has a problem with EGA they bought a year ago.
I asked if they could look for out of the ordinary symptoms that may be on the branches or bark.
The damage is in somewhat of a spiral pattern. Conifers have a spiral vascular system, correct?..
Could this just be winter damage? Could it be cankers?
I know that it's normal for them to drop old branchlets at this time too; but this case seems to be something more.
I'd love to hear your opinion.
Thanks,
Caroline

This could be several things. I would like to see a plant sample to really make a proper diagnosis. Yes it could be cankers, it does not seem to to be insects or abiotic. If you can bring in a sample.
