Recently, turfgrass has received scrutiny from the public in many parts of United States due to misconception that it limited benefits and negative impacts on environment. These are often associated with water chemical usage during maintenance. Even these ill-advised concerns, remains an important component urban landscapes. Contrary opinion, numerous environmental, ecological, economical, social, societal benefits. This review paper summarizes highlights systems.
Abstract Annual bluegrass ( Poa annua L.) poses significant challenges in managed turfgrass systems due to its adaptability and resilience. This study explores publicly available information on performance of several organic or nonsynthetic herbicides for annual control address this issue. Through a keyword frequency analysis using Google Scholar, the prevalence weed treatments was examined, revealing association between search engines, key phrases, management types general dominance...
Abstract Periodic drought and shortage of potable water have led many municipalities in Florida to set limitations restrictions on irrigation frequency for home lawns. These do not take into account turfgrass health response may be inappropriate across different species cultivars; hence, there is a need identify genotypes that could sustain quality performance under reduced irrigation. A study was conducted at the University Plant Science Research Education Unit Citra, FL, assess 10...
Abstract Water shortages have become more chronic as periodic droughts prolong and water demand for urban agricultural use increases. Plant drought responses involve coordinated mechanisms in both above‐ below‐ground systems, yet most studies lack comparisons of root canopy under scarcity recovery. This is particularly true research focused on warm‐season turfgrasses sandy soils with extremely low holding capacity. To address the examination stress recovery responses, this study compared...
Tropical signalgrass is one of the dominant weeds in Florida turfgrass industry and potentially troublesome for southeastern industry. especially problematic St. Augustinegrass sod producers because lack control options.

Abstract Poa annua L. (annual bluegrass) is a common weed in turfgrass and has been reported resistant to 12 different herbicide sites of action, with various combinations multiple‐herbicide resistance having identified. To quantify the extent herbicide‐resistant P. , ResistPoa Project (resistpoa.org) surveyed 1349 populations for nine action one plant growth retardant. Herein, we report results from sequencing known target site mutations found 5‐enolpyruvylshikimate‐3 phosphate synthase (...

Abstract Measuring water use on U.S. golf courses is an essential component of measuring best management practice adoption. To provide timely and meaningful education regarding current use, continued measurement course necessary. The objective this study was to assess the related practices in 2020. A survey developed distributed electronically 14,145 with 11% responding. Since initial conducted 2005, applied as irrigation declined by 29% from 2.38 1.69 million acre‐ft. Factors contributing...
Golf facilities account for 2.3 million acres in the United States. Numerous turfgrass species are managed on US golf facilities, but may change turfgrasses depending numerous variables. Knowing which grown and how selection has changed would provide important information to scientists, managers, policymakers. The objective of this survey was measure use 2021 determine whether changes have occurred since 2005. A developed distributed via e-mail 13,938 with 1861 responding. From 2005 2021,...
Abstract ‘FSA1602’ (Reg. no. CV‐294, PI 704119) hybrid St. Augustinegrass [ Stenotaphrum secundatum (Walter) Kuntze] was developed and released by the Florida Agricultural Experiment Station, University of Florida, in 2018. FSA1602 has a distinct olive blue‐green color high levels resistance to gray leaf spot, take‐all root rot, excellent shade tolerance turfgrass quality (TQ). It is targeted for use residential commercial lawns southern United States. coarse textured leaves similar width...
Plain Language Summary Poa annua is a troublesome weed in turfgrass areas such as golf courses, athletic fields, lawns, and sod farms. Controlling P. made more difficult by the growing problem of herbicide resistance, inherited ability plants to survive applications that would normally be lethal. Researchers from 13 academic institutions collected 866 populations different states systems better understand extent this problem. Collections were divided treated with four herbicides one plant...
Degree‐day modeling applications in turfgrass management have recently seen increased interest. The predictive capacity of any degree day model is dependent on an accurate determination the basal growth temperatures for species under consideration. objective this study was to determine and rate constants eight warm season turfgrasses (five species).

Abstract A novel coronavirus, termed COVID‐19, spread worldwide and become a global pandemic in 2020. Forecasts show that COVID‐19 will cause substantial economic contraction affecting almost every industry. Managed turfgrass, particularly urban settings, has many positive societal environmental benefits. In contracted economy, resources be available to manage turfgrass achieve these benefits? this paper, we outline the benefits of managed on golf courses, playing fields, recreational parks,...

Due to complex interactions between social and ecological systems, herbicide resistance has classic features of a “wicked problem”. Herbicide-resistant (HR) Poa annua poses risk sustainably managing U.S. turfgrass but there is scant knowledge guide its management. Six focus groups were conducted throughout the United States gain understanding socio-economic barriers adopting herbicide-resistance management practices. Professionals from major sectors (golf courses, sports fields, lawn care,...
