brown spots on cherries

Asked June 30, 2016, 11:41 AM EDT

We have a mature (10-12 yrs)north star sour cherry tree. The past two harvest have been plagued with brown spots on the surface that damages the flesh to the pit. We've not found worms. it looks like a bruise but I don't think it is because the spots can appear anywhere, on the top, the bottom or on the sides of the fruit. It's on a large percentage of the fruit and seems to be worse this year than last. Any suggestions? thank you

Brown rot (a fungal disease) may be responsible for the brown spots on the cherries. See the following website for information on brown rot.
