Pecan affected by Xantomonas Campestris: is it possible?
Hi from Italy!
I just asked about this problem on my cape fear little plant.
It is a 3 yo plant, planted in March 2016.
This year in June I found on the lower part of some leaves strange black spots and in July I noticed strange scorchings on them.
The problem did not stopped and leaves started to falm down in September.
Now, a lot of leaves fell down and I decided to have some analysis on them.
I thought it could be pbls due to xylella fastidiosa multiplex.
According to the plant patologist it is also a bacterial disease but it is due to Xantomonas Campestris, a bacterium that affects stone fruits.
Have you ever heard about it on pecans?
He told me to treat with copper salts after all leaves will fall.
By the way, I use on my plants bordeaux mixture, is it OK or are there other copper fungicide better than this against bacterial disease?
Thank you very much!
Ps: just found that xhantomonas campestris juglandis affects walnuts and its the cause of canker.
