Spots on peony leaves #752658

Asked May 28, 2021, 8:12 AM EDT

Wondering if you can tell me what is causing these spots on my peony leaves and if there is a recommended treatment. I have included a photo. Thank you in advance. Madeline Mayhood

Expert Response

I'll submit the image to our disease clinic for review.  They are going to want to know if there has been any chemicals applied to the plant or in the vicinity, including any herbicides.

I'm afraid our lab was not able to determine any causal agent based on the the single image of the single leaf submitted.

If you could submit the range of images our lab recommends, that may provide more information that would be useful for an accurate diagnosis.

This document specifies the range of images for a good digital submission (https://spes.vt.edu/content/dam/spes_vt_edu/documents/plant-disease-clinic/submitting-samples/Guidance%20for%20Submitting%20a%20Good%20Digital%20Sample%20to%20the%20Plant%20Disease%20Clinic_V1.1.pdf)

Hi Ed,
I do not spray or use chemicals/herbicides of any kind - on my peonies or anywhere else on my property. 
Thanks for helping me get to the bottom of this. My peonies performed beautifully this year although the spots (just on one of about 40) are worrisome. I was unable to find any info on the internet that matched the photo I sent. 
With appreciation and kindest regards,
Madeline Mayhood
