Underdeveloped raspberry canes

Asked May 25, 2019, 10:50 AM EDT

See attached images of Caroline ever bearing raspberries. There are 2 areas in our patch where the canes are underdeveloped canes with dwarfed leaves. What is the cause?

Thank you,

We have a Plant Diagnostic Laboratory at NMSU where specialists (pathology, entomology, weed scientist) could take a look at plant samples if you're willing to prune off some representative stems, leaves attached. Put them into a box or paper bag, along with leaf samples (see below)

Print your attached photos in color. Cut some fresh sections of affected branches, put them into a box or bag and take all of this to your County Extension Service office:

3229 Rodeo Rd, Santa Fe, NM (at the fairgrounds).
(505) 471-4711---FYI. Your County Agent is Tom Dominguez. Office hours are basically 8-430, M-F.

They will have you fill out a simple submission form with your fresh sample. You might note how old these plants are---especially the ones with symptoms. Did they do that last year, too? Also, what have you applied to the berry plots this year? These and other questions will be on the form---just a heads-up.

They will pack your specimens and completed form and ship it all to us at NMSU---no charge to you for shipping or diagnosis.

Diagnostic information will be returned to you through the agent's office. Response time will be fairly quick, but, chances are, the pathologist will likely try to 'plate out' any pathogens in the tissue which can take several days.

Another request from me---the entomologist on the team---pick some of those tightly curled leaves and preserve them in some rubbing alcohol (91 or 95%), please. A pill vial will work for this; use some saran wrap under the lid to keep it from leaking (we hope) and put the vial into a small ziplock baggie. (double protection from leaks). We await........




Thanks so much for your response. My husband will be up at the extension on Rodeo Drive in Santa Fe this Friday. He will bring some raspberry samplings and some from our Native NM Locust tree that is 13 years old and started having curling leaves last year.

Thanks again.
