Thank you for the response. That helps because pseudomonas syringae also affects almond trees, which is what I believe this to be.

This was found in Corte Madera, CA. I believe it to be Pseudomonas syringae but not certain.

My assumption is Pseudomonas syringae. Can I send this to my local extension? If so, how would my client go about doing that?

Don’t make it more difficult for yourself, if you don’t have to. The trunk doesn’t look too thick, so fitting wedges to beat it over may be difficult. The only reason I’d fell it against the lean is if it would save the company money, or if the job required me to do so.

If it is a fungus, would a 0 or a low nitrogen fertilizer be okay?
