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.
