Nitrogen utilization in creeping bentgrass
Efficient approaches for screening nitrogen utilization efficiency (NUE) of turfgrasses are needed, since nitrate contamination of ground water is a concern on golf courses. In the first study, the conditions of N utilization of fourteen bentgrass cultivars were compared in hydroponic solution …

Topdressing and aerification programs on creeping bentgrass fairways
… timing 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 …

Initial Value Problems for Creeping Flow of Maxwell Fluids
We consider the flow of nonlinear Maxwell fluids in the unsteady quasistatic case, where the effect of inertia is neglected. We study the well-posedness of the resulting PDE initial-boundary value problem. This well-posedness depends on the unique solvability of an elliptic boundary value problem. …

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
… to 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 …

Total nonstructural carbohydrate (TNC) flux of creeping bentgrass receiving sequential applications of growth retardants
… during an 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.

Mold fever : how a bizarre life form penetrated popular consciousness and launched a creeping hysteria
Molds are everywhere, lately: in our homes, newspapers, and courtrooms, and on our minds. In the past few years, mold has gone from a blip on the radar of public consciousness to a major force in home inspections, insurance, litigation, and testing. Never before have people been so concerned over a …

Investigating population dynamics of Hoplolaimus galeatus and select associated relationships in creeping bentgrass putting greens
… studies aim 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
… Muhl.] are 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 …

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
… water 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 …

Nitrogen and chelated iron fertilization on the growth and physiology of creeping bentgrass (Agrostis palustrus Huds)
… were evaluated 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 …
