Yesterday I was making some grafts. On one rootstock, I made a vertical
cut down the stem for a chip bud graft. When the cut piece fell away,
instead of a healthy looking interior, the cut was covered with what
looked like a layer of sawdust. At the base of the cut, there was a
small hole and I was able to extract a small worm from the hole. It
looked somewhat like a white grub, but it was diamond shaped and flat
instead of round, about 1/4" long. I'm assuming the rootstock will
eventually die from this damage, but I'll just leave it to see what
happens. I should add that the rootstock has been in the ground for over
a year and is not fresh from the nursery. Any ideas of what this worm
might be?
Thanks,
