| Abstract/Contents: | "Swards of Poa annua in the central U.S. commonly display symptoms of yellowing and necrosis when daily air temperatures average 28-32 C for 10-14 days or longer. Water stress is not judged to be responsible for this decline of P. annua. In 1983, frog-eye patterns of yellowed P. annua appeared after 14 days then temperatures averaged 31 C and ranged from 25-37 C. Examination of afflicted crowns and roots revealed black lesions (ca. 2 mm), dark runner hyphae, and a general reduction of root mass. A Gaeumannomyces-like fungus was isolated from the diseased roots and crowns. The roots and crowns of P. annua, seeded in soil infested with oat grains colonized with the fungus and incubated at six different temperatures for 28 days, were rated for disease severity. The fungus was pathogenic at 25-33 C (optimum = 31 C), but not pathogenic at 23 or 35 C. At 30 C, P. annua and Triticum aestivum were very susceptible, P. pratensis was mildly susceptible and Agrostis palustris, Lolium perenne, and Avena sativa were not susceptible. We suggest the name Poa Patch for this disease of Poa annua." |
