چکیده
SUMMER 2000 6 NYSTA Research Reports A study was conducted to evalu ate golf putting green establish ment procedures with four creeping bentgrass (Agrostis palustris Huds.) cultivars: Penncross, Penn A-4, L93, and SR1119. Five seed rates were used (0.5, 1.0, 2, and 4 lb.) with five seed treatments: metalaxyl (Apron), Pseudomonas aureofaciens, Azospirillum brasilience, Enterobacter cloacae, and untreated seed. Seeding was undertaken twice, in June 1997 and August 1998. Seedling survival, morphology and rooting were examined. A sand (pH 7.8) putting green was constructed to “California” specifications. Data were collected in the establishment phase (up to 12 weeks after establishment) on seedling survival, visual cover and plant morphology. In addition, visual quality and root mass distribution data were collected the second season on the matured plots. Disease and drought occurrences were rated on both juvenile and mature turf. Seed rate strongly influenced all measured parameters. Specifically, seed rate was inversely related to seedling survival and incidence of Establishment Procedures Influences Seedling Survival, Morphology, and Rooting of Creeping Bentgrass

Soil Amendments and Fertilizer Source Effects on Creeping Bentgrass Establishment, Soil Microbial Activity, Thatch, and Disease
Natural organic fertilizers require microbial degradation for nitrogen (N) release, but their ability to promote rapid turfgrass establishment has not been well documented in newly constructed sand-based rootzones. This 2-year field study evaluated the influence of two general fertilizer and soil amendment programs for their effect on establishment and quality of three creeping bentgrass (Agros...
متن کاملCreeping Bentgrass Cultivar Influences Biocontrol
Printed on recycled paper SUMMER 2001 24 A Healthy Ecosystem Inconsistent performance of biological control strategies for turfgrass disease control has limited the adoption of this technology into IPM programs. A major contributing factor to this variable performance in agricultural systems is the cultivar to which biological control organisms are applied. In a recent study, our goal was to de...
متن کاملEstablishing and Trafficking New Bentgrass Putting Greens
Establishing and Trafficking New Bentgrass Putting Greens Golf turf managers are pressured from the golfing community to reduce the establishment time of playing surfaces. To this end, accelerated grow-in procedures are implemented that eventually permit play on surfaces that are less than prepared to receive traffic. Research hassuggested that accelerated grow-in procedures and premature traff...
متن کاملCytochrome P450 Inhibitors Reduce Creeping Bentgrass (Agrostis stolonifera) Tolerance to Topramezone
Creeping bentgrass (Agrostis stolonifera L.) is moderately tolerant to the p-hydroxyphenylpyruvate dioxygenase-inhibiting herbicide topramezone. However, the contribution of plant metabolism of topramezone to this tolerance is unknown. Experiments were conducted to determine if known cytochrome P450 monooxygenase inhibitors 1-aminobenzotriazole (ABT) and malathion alone or in combination with t...
متن کاملRNA-Seq Analysis of the Sclerotinia homoeocarpa – Creeping Bentgrass Pathosystem
Sclerotinia homoeocarpa causes dollar spot disease, the predominate disease on highly-maintained turfgrass. Currently, there are major gaps in our understanding of the molecular interactions between S. homoeocarpa and creeping bentgrass. In this study, 454 sequencing technology was used in the de novo assembly of S. homoeocarpa and creeping bentgrass transcriptomes. Transcript sequence data obt...
