Dead Spot Severity, Pseudothecia Development, and Overwintering of Ophiosphaerella agrostis in Creeping Bentgrass.
ABSTRACT Dead spot (Ophiosphaerella agrostis) is a damaging disease of young </=6 years old) creeping bentgrass (Agrostis stolonifera) golf greens. The objectives of this 3-year field study were to determine the peak periods of dead spot activity based on increasing patch diameter and pseudothecia development, and to determine where O. agrostis overwinters. Patch diameter generally increased at...
متن کاملNitrogen Source Impact on Dead Spot (ophiosphaerella Agrostis) Recovery in Creeping Bentgrass
Dead spot is a relatively new disease of creeping bentgrass (Agrostis stolonifera L.) incited by Ophiosphaerella agrostis Dernoeden, M.P.S. Câmara N.R. O’Neill van Berkum et M.E. Palm. Limited information is available with regards to chemical and cultural management strategies for dead spot. Two field studies were designed to evaluate the influence of various fertilizers and iprodione on the re...
متن کاملGenetic Diversity Among Ophiosphaerella agrostis Strains Causing Dead Spot in Creeping Bentgrass
Dead spot is a new disease of young creeping bentgrass (Agrostis stolonifera L.) putting greens in the United States. The disease is incited by Ophiosphaerella agrostis Dernoeden, M.P.S. Câmara, N.R. O’Neill, van Berkum, et M.E. Palm, a previously undescribed pathogen that first was isolated in 1998 from a golf course in Maryland (1,3). In the same year, the disease was confirmed on creeping be...
متن کاملPromoter analysis in transient assays using a GUS reporter gene construct in creeping bentgrass (Agrostis palustris).
Transient expression profiles for several chimeric beta-glucuronidase (GUS) gene constructs were determined in tissues (young leaves, mature leaves and roots) of creeping bentgrass (Agrostis palustris, cv. Penn A4) following microprojectile bombardment. The constructs analyzed consisted of the uidA (GUS) reporter gene driven by four different promoters (ubiquitin 3-potato, ubiquitin corn, ubiqu...
متن کاملEstablishment of transgenic herbicide-resistant creeping bentgrass (Agrostis stolonifera L.) in nonagronomic habitats.
Concerns about genetically modified (GM) crops include transgene flow to compatible wild species and unintended ecological consequences of potential transgene introgression. However, there has been little empirical documentation of establishment and distribution of transgenic plants in wild populations. We present herein the first evidence for escape of transgenes into wild plant populations wi...
