I noticed today on my one year raspberry cane some type of growth. Has anyone seen this before or know what it is? Should I remove the cane?

Thanks,
Kris

I've never seen that sort of thing on raspberries but It looks like it could be an insect.

I had a whole bunch or pretty extreme growths late last season with what I'm nearly sure was a gall wasp. I cut open the growths and there were a bunch of larva living in there. If your plant is vigorous, which it looks like, you might want to go ahead a lop it off and take a look inside the growth. It would sure give the good folks here more information to work with.

Here's my post from late last summer

I wonder if it's Diastrophus nebulosus

It appears after a bit of reading base on the replies I got on here that it is likely a gall wasps (Diastrophus nebulosus).

I circled in red the little translucent larva which are maybe 2mm long.

Thanks for updating with pictures - I've not seen anything like that on my raspberries but glad I can add that to my mental library now
