Drechslera diseases are part of a group of diseases caused by fungi that were once cataloged in the genus Helminthosporium. Over the years, taxonomists have revised the genus Helminthosporium to include the genera Drechslera, Marielliotta, Bipolaris and Exserohilum.

Rust pustules.

Identification and Management of Turfgrass Diseases, Page 18

Reviewed

Rust occurs to some extent on all turfgrasses, but the rust fungi are generally host specific. Rust is most severe on susceptible cultivars of Kentucky bluegrass, tall fescue, perennial ryegrass and zoysiagrass. Rust symptoms usually appear in late August to early September and continue through the fall months.

Ascochyta leaf blight.

Identification and Management of Turfgrass Diseases, Page 04

Reviewed

Ascochyta leaf blight results in the rapid development of large irregularly shaped, straw-colored patches on Kentucky bluegrass and occasionally on tall fescue and perennial ryegrass during the summer. Because Ascochyta spp. are primarily foliar pathogens, diseased turfgrass usually recovers relatively quickly.
