Hi, you can see the pictures in fb page here
https://www.facebook.com/permalink.php?story_fbid=1644130822629124&id=100010966652076 the papaya leaves have stopped growing, they are yellowish, thick and rigid. My friend suspects ringspot virus. The tree has been sprayed with insecticide.
Your suggestions please if it can be healed. Or, would it be better to completely destroy the diseased tree so the disease does not spread?
Thank you!
