I have these tiny black dots on my sweet Caroline potato vine that has been in a greenhouse. It's almost like it is part of the plant.
They do no pick off. I have searched for a disease or virus online to no avail. The closest I have found is edema, but all the pics on line show it like blisters and not black. Any ideas out there? thanks
I tried to edit the picture, but could not, so I am sending an additional one that has a better resolution.
