Rhubarb leaf issue #791697

Asked May 19, 2022, 3:31 PM EDT

Planted rhubarb plants from another gardener last year. A couple of leaves have these spots this year. What is it & how do I treat? Thanks.

Thank you for writing.
Just pull off those leaves (do not cut them off).
I do not think it is a disease.

it looks somewhat like edema of the leaf.   can you send closeups of the undersides of two leaves?
