Orange Rust
Gymnoconia sp.
Lower leaf surfaces become covered with blister-like masses of yellow-orange spores by late May or early June. These spores serve to spread the disease to other plants. In addition, heavily infected leaves may die,and infected shoots will be weak, spindly and have very few, if any thorns.
