Working in the south of France I have found a disease affecting bay laurel there. I wondered if anyone knows what it is or if I need to do anything about it. There are reddish-brown patches on the bark - anything from 2-10 inches across, they are edged in silver. There does not seem to be any lesions or other symptoms. Although a few trunks have had a black rot running down inside some of the tree rings. This might be related? Any ideas? thanks,

a fungal infection may have caused this, not sure what to do or how to cure them. maybe you just have to keep them dry and take off any infected leaves.

Could it be phytophthera? Are the patches flush with the bark or do they look like "mushroom" sort of growth?

The patches are flush with the bark. I thought maybe a fungal growth or worse phytopthera - but didn't know if bay trees were subject to the ramorum strain - hope not! It could be either as we have had torrential rain here after very hot summer, and it is on top of a hill so very windy too - a lot of strain for plants to live under...!
