Good evening gardeners I'm hoping someone can help me out here as I've come into an issue with my pear tree. At first I thought it was pear tree leaf blister mites, but the spots on the leaves are black. Now I'm convinced it's some sort of fungal issue as it's spread all over the tree after the few days of rain. (Maybe Venturia pirina or Fabraea leaf spot?) Thoughts? Thanks in advance.
