Nitrogen utilization in creeping bentgrass
… the conditions of N utilization of fourteen bentgrass cultivars were compared in hydroponic solution culture. There were significant differences between cultivars in plant tissue dry weight, tissue N content, root absorption efficiency (RAE), and NUE. From a whole plant basis, 'Penncross' …

Topdressing and aerification programs on creeping bentgrass fairways
… of topdressing and aerification for creeping bentgrass(<i>Agrostis stolonifera<i> L.) fairways and the effect that these two cultural practices have on soil physical properties have not been fully assessed. The first objective of this study was to determine the optimum timing of topdressing …

Management of annual bluegrass and bermudagrass in creeping bentgrass greens
Management of creeping bentgrass is relatively intense when maintained as a golf course putting green. The intense nature of the cultural practices required to maintain creeping bentgrass as a putting surface has a cumulative negative impact on this same environment. Aerification, verticutting, …

Development of genetic transformation systems in creeping bentgrass (Agrostis palustris Huds.)
As a first step toward improving creeping bentgrass (Agrostis palustris Huds.) via genetic engineering, this study was conducted to develop genetic transformation systems in creeping bentgrass. Establishment of embryogenic cell cultures is a prerequisite for crop improvement via genetic …

Creeping bentgrass response to plant growth regulating substances and annual bluegrass competition
Creeping Bentgrass (Agrostis stolonifera var. palustris (Huds.) Farw.) is the most widely used cool-season turf grass used for putting greens in North America. Frequently it becomes invaded with a persistent weed, annual bluegrass (Poa annua L.). Studies were conducted on a predominately annual …

Chemical and biological control of silvery threadmoss on creeping bentgrass putting greens
… annual bluegrass but not to "¥Penn A4"" creeping bentgrass. Both organisms have potential to be effective biological controls for silvery threadmoss; however, host specificity indicates Alternaria sp. may be a better choice. Data from these experiments suggest herbicides in two chemical classes …

Lateral Movement of Herbicides on Golf Course Fairways and Effects on Bentgrass Greens
… perennial ryegrass and across adjacent creeping bentgrass. Irrigation had no effect on perennial ryegrass control but reduced visible track length and injury of neighboring creeping bentgrass. When treated perennial ryegrass was not irrigated prior to simulated mowing, tire tracks were evident on …

Total nonstructural carbohydrate (TNC) flux of creeping bentgrass receiving sequential applications of growth retardants
… 8 week period increased verdure TNC of creeping bentgrass 2 WAT in the greenhouse experiments. However, TNC content of treated turfs was significantly lower than untreated control from 6 weeks after an initial application both in greenhouse and field studies.

Investigating population dynamics of Hoplolaimus galeatus and select associated relationships in creeping bentgrass putting greens
… to quantify the relationship between creeping bentgrass health and nematode populations, and to evaluate a qPCR diagnostic method. Plant growth regulators (PGRs) are used to optimize turfgrass growth and reduce management inputs, but anecdotal evidence suggests a link between increased …

Optimizing Topramezone and Other Herbicide Programs for Weed Control in Bermudagrass and Creeping Bentgrass Turf
… problematic weeds in bermudagrass and creeping bentgrass turf. Increased incidences of herbicide resistant weed populations and severe use restrictions on formerly available herbicides have increased need for selective, postemergence control options for these weeds in creeping bentgrass and …

Effects of Nitrate and Cytokinin on Nitrogen Metabolism and Heat Stress Tolerance of Creeping Bentgrass
Creeping bentgrass (Agrostis stolonifera L.) is a major low-cut cool-season turfgrass used worldwide. The objectives of this research were to: 1) to gain insight into the diurnal fluctuation of N metabolism and effects of cytokinin (CK) and nitrate; 2) to characterize the impacts of N and CK on …

Creeping Bentgrass, Kentucky Bluegrass and Tall Fescue Responses to Plant Growth Stimulants Under Deficit Irrigation
… conservation practices within Virginia. Creeping bentgrass (<i>Agrostis palustris</i> "L93"), Kentucky bluegrass (<i>Poa pratensis </i>"Midnight"), and tall fescue (<i>Festuca arundinacea</i>) Dominion blend were evaluated under deficit irrigation and upon exogenous application of plant growth …

A Comparative Study of Composted Organic Wastes and IBDU Fertilizer in Nitrogen Utilization by Bentgrass Cultivars
This research project that was conducted to provide evidence that composted organic waste materials do provide comparable nitrogen absorption efficiency in relation to an organic slow release fertilizer. Western's compost facility supplied the two different organic wastes, which had been composted …

Nitrogen and chelated iron fertilization on the growth and physiology of creeping bentgrass (Agrostis palustrus Huds)
… on the growth and physiology of creeping bentgrass. Iron, when applied alone, did not provide a satisfactory turf color during the winter and early spring. However, spring root growth was generally increased with iron while carbohydrates remained high, but top growth was low when compared …

Some physiological responses of two grasses as influenced by temperature, light, and nitrogen fertilization
… Cynodon dactylon (L) Pers., and Cohansey bentgrass, Agrostis palustris Huds. Each of the grasses was included in a field experiment to study the influence of nitrogen rates on carbohydrate reserves at different seasons. Increased temperatures with bentgrass caused decreased carbohydrates, …

Evaluation of bacterial strains for control of dollar spot on creeping bentgrass and brown patch on tall fescue
… Bennett, causal agent of dollar spot on creeping bentgrass (Agrostis palustris Huds.); and Rhizoctonia solani Kihn, causal agent of brown patch on tall fescue (Festuca arundinacea Schreb.), are important pathogens of turfgrass. This research evaluated the ability of twenty bacterial strains of the …

The influence of high temperature stress and herbicides on the susceptibility of creeping bentgrass (Agrostis palustris) to Curvularia lunata
… lunata as a primary pathogen of creeping bentgrass (Agrostis palustris) has been debated in the literature for many years. The most recent and most complete evidence indicates that this fungus is a weak pathogen, colonizing only senescing tissues. In the present study, four groups of …
