Crown gall on Orange tree

Raimeiken - z9b - Peoria, AZFebruary 4, 2012

This Navel orange tree that we've had has always been slow growing, and in some years, like this past year did not produce any fruits at all. I snapped a picture of its trunk.

That's crown gall on it right? I suspect that it is because a bunch of my oleander trees in my back yard had crown gall and I had to dig them out and dispose them.

Yep, that's the dreaded crown gall. I am so sorry. Crown gall is insidious. There's not much you can do to cure or prevent this disease, once it has been introduced into your environment.

It's strange that none of the web-sites describing citrus diseases seem to mention crown gall. The only picture I could find was of a young citrumelo plant with symptoms.
Is it very unusual? Lots of photos of wasp galls!

I don't think that it is very common with citrus. But those citrumelo images were not the only ones you've seen! There's an excellent picture of crown gall affecting an orange tree right in this very thread! ;-)

Raimeiken's citrus was made susceptible because of its location near the diseased oleander. Since we know that this bacterium is very easily transmitted via any tiny opening in the plant...pruning cuts, lenticels, insect damage, etc...the chances of this and almost any plant becoming infected is pretty good.

Some plants can live with an active infection for quite some time without breaking out in the 'tumors' we can recognize right away. However, the plants will usually be stunted and unproductive.

Yes unfortunately for me, I only learned about crown gall not too long ago. My oleanders have had it for years and I most likely spread it to this orange when I was pruning it with the same shears I used on the oleanders.
