I have recorded what seems to be a similar problem on some younger cherries near Hexham. Please see my thread here for pictures. From what I can tell, it is not canker as there is no bleeding or sap coming from the stem. It looks much more like a fungal or bacterial pathogen affecting just the leaves. From what I have read so far, it seems more likely to be the Leaf Spot associated with Cherry, at least in my case. The blossom wilt seems to affect the whole leaf, whereas in my case there are small spots and shot-holes appearing as the leaf shrivels and dies off. I have also noticed other species, such as Rowan, in close proximity to the infected cherries showing some signs of illness. I think it must be to do with the warm, wet summer we are having being perfect for fungus and other pathogens, as the sites in question are not stressful for the trees in any other way. I think I am going to try removing as much infected foliage as possible and burning it, then spraying with some sort of copper fungicide. Does anyone know a good place where I can get hold of this? many thanks, Luke

I have now managed to upload the pictures to a forestry blog, see here: Forest Life: Fungal disease of Cherry trees will no longer be trying to upload via facebook in future!!! Thanks, L

Hello all - A new poster to the ArbTalk forum here. I am generally speaking a forest manager, but have been asked to look at some Wild cherries in the garden of a neighbour as a favour. The leaves on said cherries have been "curling up and dying" - my first thought was bacterial canker but they had not seen any resin bleeding or oozing so had to rethink that one. There are some 9-10 trees in their garden infected, with a small Rowan close up underneath one of the said trees also showing some signs of an infection. Some pictures here: view of the whole tree: It seems so far from the reading I have done on this website and elsewhere it is not bacterial canker or any environmental factors, such as poor drainage or soil conditions. The only thing I can seem to find which matches is something called leaf spot - link to RHS site here The only advice for treatment of this condition seems to be to remove as much foliage as possible to reduce pathogen / inocculum levels and to possibly treat the tree with a copper fungicide to limit the spread. Does anybody have experiences with this or similar diseases, and can you advise on the effectiveness of above treatments? Any advice or differing diagnoses much welcomed. many thanks, Luke Edit - the links to pictures above appear to be broken - can anyone suggest where to post images to make it easy to share them online? Many thanks
