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.

Gray leaf spot, also called blast, occurs in most areas of the country where perennial ryegrass is grown. Disease development is sporadic with little or no disease development in some years. Nevertheless, the potential destructiveness of gray leaf spot forces many turfgrass managers to apply preventive fungicide applications every year.
