ID pest / disease on olive tree

Postby Amelda » Sun Dec 14, 2014 7:02 am

Hi all, can anyone help identify what is happening with my olive? The trunk has patches that look like it's been burnt, but just in patches. The bark is turning brittle where this disease/bug is. It was just one patch initially, now there is three or four. I am in melbourne northern suburbs. Tree is a couple of years old.

It looks like a fungal problem. I would treat with a fungicide to see if this helps.

I agree, almost certainly fungal. It looks a lot like stem canker that Grevilleas can get (not saying that is what it is, just similar-looking symptoms.)

I did find this .... I don't know whether it is relevant to Australia or not, but I suspect those affected areas will eventually split.
