Roya on tarragon
Tarragon Morocco
Good morning, the tarragon has a disease on the leaves and we do not have much idea of what can be. Maybe Roya?. I know that is quite difficult recognize a disease through a photo but maybe you are familiarized with it.
Thank you.
Thank you.

Agree it could be rust disease, but hard to confirm from these images. Is it possible to upload some clear close-up images?
Symptoms: Appearance of yellow or white spots on the upper side of leaves; bright orange or yellow pustules on the underside of the leaves; leaves may turn yellow; growth is stunted and the plant may become stunted.
