Book excerpt: Annual bluegrass is the most widespread turfgrass species maintained on intensively cultured turf. Indeed, most of the top golf courses in the world have greens composed, at least in part, of this type of turfgrass There have historically been conflicting beliefs as to why many golf courses have problems with annual bluegrass populations during the summertime months. Through analysing the industry's latest research and pest control technologies the author helps put to rest this debate and offers methods for growing and maintaining healthy annual bluegrass. Written by leading experts in their field, this book contains many colour photographs and is a practical guide for golf course and turgrass specialists.

Book Synopsis Use of Mesotrione for Annual Bluegrass (Poa Annua L.) at Cool-season Turfgrass Establishment by : Katelyn A. Venner
Download or read book Use of Mesotrione for Annual Bluegrass (Poa Annua L.) at Cool-season Turfgrass Establishment written by Katelyn A. Venner and published by . This book was released on 2011 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual bluegrass is a problematic weed in highly maintained turfgrass environments, and is difficult to control due to its adaptability to highly maintained turfgrass environments and lack of highly effective chemical control options. Mesotrione is a relatively new herbicide which has been found to show some level of control of annual bluegrass, and is safe to use at cool season turfgrass establishment. Thus, mesotrione has potential to be utilized for weed control in cultivated sod production. The objectives of this research were to evaluate mesotrione to determine: 1) tolerance of selected tall fescue cultivars, an important turfgrass species cultivated for sod, to applications of mesotrione; 2) the length of residual of mesotrione versus prodiamine, bensulide and dithiopyr for control of annual bluegrass; and 3) potential of mesotrione to control winter annual broadleaf weeds at Kentucky bluegrass establishment. Tall fescue cultivars were found to be tolerant to mesotrione applications made preemergence and preemergence plus 4 weeks after emergence at higher rates than required for weed control. Significant cover reductions were only observed at the 1.12 kg ha-1 application rate of mesotrione, which is four times the highest labeled rate for weed control. There was little difference in the response of the seven tall fescue cultivars iii evaluated suggesting minor intraspecific variability between tall fescue cultivars to mesotrione. When applied to bare ground, mesotrione provided 48% annual bluegrass control in the fall and annual bluegrass control decreasing to 20% in the following spring. Prodiamine, bensulide and dithiopyr provided much greater levels of annual bluegrass control and high levels of control were maintained into the following spring. These results suggest that although mesotrione has some activity on newly germinating annual bluegrass it is much lower relative to prodiamine, bensulide and dithiopyr. Mesotrione was found to be more effective for winter annual broadleaf weed control when applied POST compared to PRE. For overall winter annual broadleaf weed control mesotrione should be applied PRE at rates of 0.21 kg ha-1 or higher and POST at 0.14 kg ha-1 or higher. The results of these studies demonstrate that mesotrione is safe for use in newly seeded tall fescue and previous studies have shown similar findings with Kentucky bluegrass. The safety of mesotrione to these two economically important turfgrass species widely grown for cultivate sod combined with its ability to control winter annual broadleaf weeds and suppress annual bluegrass demonstrate that is a new and valuable component to an overall weed control program in cultivated sod production.

Book Synopsis Annual Bluegrass (Poa Annua L.) Control with Ethofumesate During Turfgrass Establishment by : David L. Wieneche
Download or read book Annual Bluegrass (Poa Annua L.) Control with Ethofumesate During Turfgrass Establishment written by David L. Wieneche and published by . This book was released on 1988 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of annual bluegrass on sites renovated by three different techniques. In addition, tolerance of common turfgrass cultivars was determined. Ethofumesate rates of 0.5, 1.0, 1.5 kg ai/ha, and split repeat treatments of 0.5 kg ai/ha applied twice or three times, applied preemergence, or early postemergence at the one and two leaf stage relative to perennial ryegrass were tested. Protected Least Significant Difference mean separation statistical analysis was used to determine differences at the 5% level. Differences were observed between ryegrass and tall fescue cultivars in greenhouse ethofumesate tolerance studies but not in field trials. Ethofumesate greenhouse cultivar tolerance differences did not correlate to results of field trials. All perennial ryegrass and tall fescue cultivars tested in field trials tolerated ethofumesate well at all rates. There was an initial 1 month period of growth suppression following ethofumesate application which perennial ryegrass and tall fescue appeared able to recover and annual bluegrass was not. Annual bluegrass was controlled in all trials at 0.5, 0.5 X 2, 0.5 X 3, 1.0, and 1.5 kg ai/ha ethofumesate rates and at all stages of application. Annual bluegrass reduction ranged between 83% to 100%. Perennial ryegrass cultivars Palmer, Blazer, Loretta, Dasher, and Regal, tall fescue cultivar Mustang, and 'America' Kentucky bluegrass tolerated ethofumesate. Red fescue, hard fescue, chewings fescue, roughstalk bluegrass, colonial bentgrass, and annual bluegrass did not tolerate ethofumesate. In the three establishment methods studied, annual bluegrass control was 100% in the no-till followed by surface scarification and broadcast seeding, 97.3% in the till trials with broadcast seeding, and 83% in the no till slicer seeder method.

Available in PDF, EPUB and Kindle. Book excerpt: Most people know about the presence and health effects of pesticide residues in the water they drink. However, they may not realize the impact of atmospheric transportation and deposition of pesticides on water quality. Scientific studies of pesticides in various atmospheric matrices (air, rain, snow, aerosols, and fog) provide some of the answers.
