Abstract/Contents:"Subfreezing temperatures in early May caused injury resembling several pathogenic disorders to Kentucky bluegrass. Several mistaken diagnoses were later observed. White leaf tips, often accompanied by white transverse bands across the leaves, were the primary effects of frost injury. Of 24 cultivars examined, 11 showed no color demarcation between green and white tissue, 'Merit' and 'Glade' had distinct purple margins, and the remaining 11 showed occasional purpling. These symptoms resembled infections caused by Ascochyta, Nigrospora, or Lanzia/Moellerodiscus. Ascochyta was isolated from some spots, suggesting a saprophytic relationship. Shoots and tillers were damaged in pockets, especially where closely mowed. Their gray-brown coloration suggested Helminthosporium infections. Effects of low temperature were confirmed by growth chamber tests at -5 C."
