Creeping bentgrass response to plant growth regulating substances and annual bluegrass competition
… it becomes invaded with a persistent weed, annual bluegrass (Poa annua L.). Studies were conducted on a predominately annual bluegrass area managed as a putting green to attempt to quantify the impacts of plant growth regulator, seeding rate" and season on the success of introducing creeping …

Evaluation of Novel Techniques to Control Annual Grasses in Intensively Managed Turfgrass Systems
Annual grassy weeds are problematic in intensively managed turfgrass systems due to a lack of selective and affordable control options. Four projects were conducted from 2020-2023 to evaluate novel techniques for Annual bluegrass (Poa annua L.), goosegrass (Eleusine indica L. Gaertn.), and smooth …

The construction, irrigation and fertiliser nutrition of UK golf greens
… fertiliser. Ingress of the weed species Poa annua (L.) occurred mainly on the soil constructions and its rate of ingress was enhanced by increased nitrogen input. Golf ball roll and various aspects of their behaviour after impact onto the turf with simulated 5-iron flight characteristics …

Prohexadione Calcium for Turfgrass Management and Poa annua Control and Molecular Assessment of the Acetolactate Synthase Gene in Poa annua
… the most expensive practice on golf courses and annual bluegrass (Poa annua L) is the most challenging weed problem in professional turf. The plant growth regulators trinexapac-ethyl and paclobutrazol are commonly used in VA for these two costly and challenging jobs. Prohexadione calcium (PC) is …

Postemergence control of annual bluegrass with mesotrione in Kentucky bluegrass
Annual bluegrass (Poa annua L. var Hausskn Timm) is a common grass weed species in turf. A lack of environmental stress tolerance, combined with prolific seed production and a highly competitive growth habit makes annual bluegrass difficult to maintain, but also difficult to get rid of from an …

Physiological and Environmental Basis of Turfgrass and Weed Response to Mesotrione Formulations
… plant species when applied to foliage or roots. Annual bluegrass (Poa annua L.) absorbed 2- to 4-fold more radioactivity than Kentucky bluegrass (Poa pratensis L.). Both species absorbed less radioactivity through roots than through foliage and root absorbed radioactivity was more often exuded …

Phenology and Management of Annual Bluegrass Weevil on Virginia Golf Courses
Annual bluegrass weevil (Listronotus maculicollis Kirby) (Coleoptera: Curculionidae) (ABW) is a major pest of annual 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, …

Evaluation of fine fescues as alternative golf course fairway turfgrasses
… (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 course fairway turf. Low-input fine fescue …

The Effect of Fe-sulfate on Annual Bluegrass, Silvery Thread Moss, and Dollar Spot Populations Colonizing Creeping Bentgrass Putting Greens
Annual bluegrass (Poa annua L.) is the most problematic 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 …

Influence of Annual Bluegrass on Putting Green Trueness and Control of Weedy Poa Species in Kentucky Bluegrass and Creeping Bentgrass Turf
Annual bluegrass (Poa annua L.) and roughstalk bluegrass (Poa trivialis L.) are among the most troublesome grass weeds on golf courses throughout the United States. Herbicides for selective control of these weeds in cool-season fairways are limited and ineffective. Methiozolin is a new isoxazoline …
