Orange tree disease question w/picture
Does anyone know what this disease is on this Valencia orange tree?
I've cut back the stem twice now and the disease has re-emerged each time. Two other branches had the disease, but when I cut them back it did not re-emerge?
Is there any spray or anything that can be used? I'm really worried it will overtake the whole tree. I lost a apricot tree to this, really don't want to lose this wonderful orange tree.
Thanks in advance.
