Rust of sheep's fescue

Festuca ovina L.

A fungal disease of sheep's fescue caused by the pathogen Puccinia elymi, manifested by the formation of yellow or orange pustules on leaves and stems.

In the reference 5 varieties crop Sheep's fescue, where this is mentioned in the description.

On sheep's fescue (Festuca ovina L.), the disease manifests as chlorotic spots which, as the pathogen develops, transform into yellow, orange, or brown pustules. When the pustules rupture, fungal spores are released, leading to premature drying of the affected leaves and thinning of the stand.

The pathogen Puccinia elymi has been identified as the primary causal agent of rust on sheep's fescue in natural ecosystems. Scientific data regarding specific races or pathotypes of the fungus, as well as specific resistance genes in this fescue species, are currently unavailable, and the agronomic assessment of cultivar resistance remains qualitative.
