If you are seeing symptoms like the images below give me a call or post a comment. We are seeing this yellowing in different areas of middle georgia and are trying to figure out if it is related to variety.
In affected fields or areas of fields leaves tend to yellow around the edges and some cup upward as seen above. The only thing that these fields have had in common so far is high numbers of potato leafhopper. This is the same little insect (1/8" ) that causes hopper burn in peanuts and there are reportedly large migratory populations.
Let me know if you have anything resembling this injury or if you have a heathy population of the above insects.
