    I forgot to mention that the leaves are from a Hawthorn tree which was planted about 2 years ago. This is the first year I have experienced this. Hope that helps and thank you for the support.

    More likely cedar-hawthorn rust? Both cedar-hawthorn and cedar-apple rust are discussed on the site below.

    Strategies 1, 2, 4, and 5 are considered organic management practices on this page: Cedar-Hawthorn Rust
