Cedar Apple Rust
On crabapple
On juniper
This disease affects the leaves of crabapples. It also infects junipers. The two of these plants in close proximity may yield a cedar apple rust.
On crabapples, the disease starts as rust colored spots on the leaves which may eventually infect the entire leaf, causing premature leaf drop.
On junipers, it will appear as a small, orange colored gelatinous growth.
This is seldom a serious disease, but it is possibly the most unsightly, especially on crabapple leaves.
