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)
