Use of tartrazine dye as a tracer to measure foliar spray retention on turfgrass
… on foliar spray retention on a bentgrass (Agrostis stolonifera L.) golf fairway. For water-based spray mixtures, the results indicated that increasing spray volume decreased foliar recovery to a plateau at around 85%. Compared to flat fan nozzles, air induction nozzles delivered the same …

Evaluation of Novel Techniques to Control Annual Grasses in Intensively Managed Turfgrass Systems
… smooth crabgrass >80% in creeping bentgrass (Agrostis stolonifera L.) and hybrid bermudagrass turf. Although similar programs also controlled goosegrass, acceptable control required more applications than are allowed on the product label. Targeted application devices (TAD), such as spot …

Prohexadione Calcium for Turfgrass Management and Poa annua Control and Molecular Assessment of the Acetolactate Synthase Gene in Poa annua
… and Kentucky bluegrass, creeping bentgrass (Agrostis stolonifera L.), and perennial ryegrass. Annual and Kentucky bluegrass absorbed more PC than creeping bentgrass or perennial ryegrass and partially explained the selectivity between these species. Translocation and metabolism of PC did not …

Physiological and Environmental Basis of Turfgrass and Weed Response to Mesotrione Formulations
… of perennial grasses like creeping bentgrass (Agrostis stolonifera L.). Field trials conducted at Virginia Tech and Blacksburg Country Club determined that several programs that integrate herbicide treatment and turf seeding effectively transitioned creeping bentgrass contaminated golf roughs …

Phenology and Management of Annual Bluegrass Weevil on Virginia Golf Courses
… bluegrass (Poa annua L.) and creeping bentgrass (Agrostis stolonifera L.) on golf courses in the northeastern United States. The asynchronous life cycle makes managing ABW difficult, putting emphasis on scouting to achieve accurate insecticide timing and acceptable control. Little is known about …

Evaluation of fine fescues as alternative golf course fairway turfgrasses
… grow high-input grasses like creeping bentgrass (Agrostis stolonifera, L.), Kentucky bluegrass (Poa pratensis, L.), annual bluegrass (Poa annua, L.), and/or perennial ryegrass (Lolium perenne, L.) on fairways. Grass species exist that are more sustainable than those currently being used for golf …

Improved Strategies for Dollar Spot Suppression Using Ferrous Sulfate
… is especially devastating on creeping bentgrass (Agrostis stolonifera L.). The fungus Sclerotinia homoeocarpa degrades the foliage by creating silver, dollar-sized depressions of dead and bleached turf. Frequent fungicide applications and cultural management strategies are required throughout the …

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 …

The Effect of Fe-sulfate on Annual Bluegrass, Silvery Thread Moss, and Dollar Spot Populations Colonizing Creeping Bentgrass Putting Greens
… weed to control in creeping bentgrass (Agrostis stolonifera L.) putting greens. The objective of this study was to transition a mixed putting green stand of annual bluegrass and creeping bentgrass to a monoculture by using fertilizers and plant growth regulators that selectively inhibit …

Influence of Annual Bluegrass on Putting Green Trueness and Control of Weedy Poa Species in Kentucky Bluegrass and Creeping Bentgrass Turf
… bluegrass control in creeping bentgrass (Agrostis stolonifera L.) or Kentucky bluegrass fairways. Another study evaluated the response of 110 Kentucky bluegrass varieties to three rates of methiozolin. Annual bluegrass has long been presumed to impact putting green trueness, or the ability …

Optimizing Topramezone and Other Herbicide Programs for Weed Control in Bermudagrass and Creeping Bentgrass Turf
Goosegrass [Eleusine indica (L.) Gaertn.] and smooth crabgrass [Digitaria ischaemum (Schreb.) Schreb. ex Muhl.] are problematic weeds in bermudagrass and creeping bentgrass turf. Increased incidences of herbicide resistant weed populations and severe use restrictions on formerly available …
