“Throughout the year pathologists receive numerous samples of yellow, creeping bentgrass or annual bluegrass (Poa annua) from putting greens. In autumn or spring, superintendents sometimes suspect that yellow tuft (Sclerophthora macrospora) or yellow patch (Rhizoctonia cerealis) diseases are the problem.”
