Biology and Occurrence
The initial symptoms of crown rust can be very similar to that of Brown Rust in wheat and barley. The infection starts on the leaf surface with orange-brown pustules, at a later stage in the disease this can spread to the leaf sheath and oat panicle.
Crown rust can be managed by the removal of volunteers and the use of an effective fungicide. If crown rust is present and not controlled it can reduce yields up to 20%.
