Today I something I've never seen before on one of the Caroline red
raspberries I planted last year. They were heavily "pruned" by deer
over the winter, to about 8 inches, and are just beginning to sprout -
green tip.
Two of the canes of one of the plants had white stuff on them that
looked fungal. At first glance it almost looked like someone had
sprayed a little white paint in their direction, although there wasn't
anything paint-like anywhere but on this plant. There were slightly
raised white patches on the cane, and towards the end (near the part
bitten off) every little thorn was covered with white. It was mostly
the top end of the cane that was affected. That would be the top 3
inches of the 8 inches of cane the deer left.
The weirdest thing was that despite a little white fuzz directly on
the green tip of the topmost bud, the bud appeared otherwise healthy,
and the green immediately next to the white stuff looked normal, not
dried, or curled, or discolored, or showing any other pathology.
I cut the two affected canes well below the white, and put the scuzzy
bits in the municipal garbage can, not the mulch pile.
Does anyone know what I saw? How serious a problem is it?
Thanks,
