Rust (Puccina cynodontis)
Many species of Rust occur on turf grasses and symptoms are normally seen in the summer and autumn. Rusts appear as small chlorotic flecks followed by orange or brown spore pustules on the leaves, either scattered randomly or in lines. The most commonly affected grasses are Perennial ryegrass, Cocksfoot and Annual, Smooth-stalked and Rough-stalked meadow grass.
