Have this loring peach that started to show what I thought was maybe bacterial spot in July. Never heard of X disease before and now worried that it might be that. I’m going to submit samples to PSU and see if they can tell me if it’s x disease or bacterial spot. Anyone ever seen this? I spray copper at leaf drop and before bud swell so this tree has been treated with copper in november last year and before bud swell in like march this year. I think I do remember the fruit having some peach scab or bacterial spot last year. We had horrible frosts this year so this and mostly all my trees don’t have fruit so I can’t use any fruit diagnoses either on this issue.
Definitely not leaf curl.
There’s also a bit of interveinal chlorosis. How’re the nutrients and pH looking? (even if there’s technically enuff phosphorus if the pH is too low, like at my orchard, the phosphorus isn’t going to be available to the tree and lead to the symptoms that are in the pictures).
