Copper spot is a foliar disease of bentgrass, with severest outbreaks occurring on velvet bentgrass. It also occurs sporadically on creeping bentgrass greens and higher cut creeping bentgrass tees and fairways. Gloeocercospora sorghi causes a leaf spot of bermudagrass and zoysiagrass as well.

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. This section covers the diseases Drechslera leaf spot and melting-out caused by D. poae and red leaf spot caused by D. erythrospila.

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 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.
