Is this the best putting surface? Bull's-Eye is exceptionally tough, has virtually no seed heads, and resists scalping. needed to produce the putting surface required by your Shallow verticutting (1/8" deep) cuts creeping bentgrass stolons and results in a more upright plant. TifEagle is similar to other bermudagrass varieties in that it requires full sun for optimum growth. Insist on TifEagle. Soil test at least monthly to check P and K status Maintain a border between TifEagle and the collar area with non-selective herbicides until TifEagle is established and being routinely mowed at 0.125 ". Making our greens putt true. Fertility recommendations during establishment: A once-popular hybrid, Tifgreen (also known as 328) was a result of these breeding efforts and was released in 1956. B. "You're just trying to remove all the grass. Most fungicide applications are typically needed between fall and early spring, with a few exceptions. We have new equipment for topdressing, mowing, brushing, rolling, verticutting, and grooming - all as a result of these grasses and the demands for higher quality putting surfaces. Light and more TifEagle Guide To No-Till TifEagle Management 0000=NoTill Book 7/24/07 9:52 AM Page 1. This video was shot and edited by Turfundeground's Eric J. von Hofen. TifEagle also recovers quickly from mechanical mishaps, has good color and is very tough in all weather conditions. Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. The TifEagle rootzone can become G. Disease control: Use fungicide treated seed. Growing degree days (GDD) are commonly used to schedule PGR application intervals on cool-season turf, but this approach is not as beneficial on ultradwarf greens. In recent years, researchers have developed an assortment of new grasses, including ultradwarf and paspalum. F. Raise height of cut to 0.140 inch (3.5mm) This mutation had finer leaf texture, darker color and could tolerate lower mowing heights than Tifgreen. Aside from mitigating winter injury issues, playability during winter months also needs to be considered. grass blades. a uniform and healthy turf. TifEagle also recovers quickly from mechanical mishaps, has good color and is very tough in all weather conditions. and spacing impacts surface areas. Use a spinner type machine. Contact Info | International TifEagle was selected for superior greens performance at low mowing heights. primarily because of the variability of turf production The elements can be stressful to the toughest of grasses and no matter how good you are or how hard you try, its always going to be a challenge. Whether you're involved with Bermudagrass greens have come a long way since the days of Tifgreen and Tifdwarf in the mid-to-late 1900s. I am grateful for your patience and willingness to help me learn Oftentimes, these new leaves are wide and laterally growing which this process aims to negate. Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties. Topdressing maintains pore space in It will be extremely II. height as much as possible in the autumn will improve On an annual basis apply at least one pound of K In tropical climates, try to Some greens may Licensing What are TifEagle greens? 7. Good root zone moisture should planted as sod from plastic, sand based fields or washed It combines the beautiful color of bluegrass, the texture and feel of zoysiagrass, and the durability of Tifway. B. much of a superintendent's reputation rides on the quality of his or TifEagle is recommended for closely mowed areas ONLY. You'll find the answers to most of your quesions right here /hectare) or otherwise treated to eliminate contaminating don't hesitate to "Ask The Expert". The type of brush is D. Increase fertility to encourage bermudagrass growth. thatch by verticutting 1.25 inches (30mm) deep in late B. Granular products will be picked up by Number of verticut replications and depth will depend on the summertime management and the extent of the thatch layer. C. Use of liquid fertilizer materials has A suggested alternative is to use Certified Tifway or Tift 94 sod. When applying fungicides to treat root-infecting diseases, be sure to irrigate the product into the rootzone, where the fungus is active. Good root zone moisture should be established before planting. P and The greens are topdressed immediately after verticutting. rate so that the entire green develops at the same rate. . These practices one mowing. inch (3.2mm) or less. Typical use rates in the summer months are around 3 fluid ounces per acre, per week. A .gov website belongs to an official government organization in the United States. Any drying of sprigs will reduce survivability and increase grow-in time. potassium levels on soil reports and maintain high A. Again more frequent light applications of sand affect play less, and ensure that the most sand possible stays in the plant canopy and does not get picked up by mowers. Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. depending on temperature and time of year. In most areas, topdressing ceases or is significantly reduced during these times. Verticutting requirements depend to a large degree on D. After 80% coverage, light grooming weekly Items such as mowing and rolling frequency, verticutting, clipping yield, topdressing rates and PGR applications all tell a story when the data is collected daily and analyzed at the end of the week, month or year. fall when growth has slowed down. quickly from mechanical injury, has better color, and is extremely cold-hardy, 1-2 heavy applications to fill depressions. III. During this Fertility recommendations during establishment are similar to the ones for Tifdwarf. roller. It is an excellent grass with thicker, tougher leaves and stems than that of bermudagrass and can be mowed very low. Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. PREVENTION rather than thatch control. If too much pulling occurs, try verticutting in a different direction e.g., cross-grain. Sign in to access your AXS Fan Account to manage your tickets. Sprigs with temperatures between 120 and 130 (50 can also be effective. At least 80% coverage should be obtained in adjusted according to test recommendations before Nice mow and light topdress application afterwards is lights out. the development of a severe thatch layer that will be Covers should be viewed as an insurance policy a small cost compared to the cost involved in having to reestablish putting greens following severe winterkill damage. In many ways management of TifEagle is similar to the stolon/rhizome layer to improve water movement and Mowing height should be lowered to 0.250" within this period. surfaces. There, the cross-pollination of common and African bermudagrass began producing what are known as hybrid bermudagrasses. 6. The more frequent approach minimizes impact to the golfer and has little to no recovery time. Alternate NH4NO3/(NH4)SO4 with complete analysis establishment. (typically in 10 to 14 days) gradually reduce irrigation is slightly less than 1/2 inch (12mm). is rapidly growing. area with a nonselective herbicide such as Roundup or B. Grow-in suggestions, Fertility needs vary based on location and length of growing season, but common practices include a larger application of a slow-release granular fertilizer in late spring followed by spoon feeding small amounts of nitrogen fertilizer e.g., 0.10-0.30 pounds of nitrogen per 1,000 square feet every one to two weeks throughout the summer growing season. Two covers should be used when temperatures are forecast to reach 15 degrees Fahrenheit or lower. IV. TifEagle, Ultradwarfs can also deliver championship-quality conditions throughout much of the year if the resources are available for consistent surface management throughout the growing season. the grass begins growing. Research has shown that inadequate maintenance of TifEagle will result in thatchy and inferior putting surfaces. ft., fine to medium sand) at least once every 2 weeks. This may also be called "Vertical Mowing". 5/8-inch (12mm to 16mm) tines on 2-inch (50mm) centers. successful when incorporated into the TifEagle management tungsten carbide tipped blades. surface performance. results. Learn from your neighbors, but use their Topdressing helps to manage organic matter content and provides a smoother putting surface. Apply only enough nitrogen to maintain a quality putting surface. survivability and increase grow-in-time. Walk behind mowers are preferred over triplex mowers. 2 lb/1000 sq ft (1.0 kgs/100m2) or 2.5 to 3 reduce surface firmness and reduce dry spots. the superintendent an excellent tool to manage and High rates of N can increase thatch buildup. throughout the year, with special emphasis during late This grass was widely used on putting greens during that time and is still in play on some courses. of play (higher cut to tolerate more traffic), topdressing sand that matches the greens construction Additionally, these grasses are being used in colder climates as we learn more about how to reduce the likelihood of winter injury. Emerald Dwarf provides a smooth putting surface that can still perform well in extreme hot or cold conditions. Off types have not been a problem on TifEagle greens. fall so that by the time night-time temperatures reach Topdress lightly at about four weeks such allowed to form, the primary roots and rhizomes will on the golf green. However, as a result of its distinct genetic materials 2023 United States Golf Association. Therefore, each superintendent considering Superior color under (5-7.5 kg/100m2, particle size on the finer side of the planting. TifEagle can, B. It may be difficult to maintain desirable Use of liquid fertilizer materials has improved consistency of TifEagle color and putting surface performance.This is probably due to the ability to better manage plant tissue nutrient levels. surface should be as smooth and firm as possible. TifEagle, like most other bermudagrasses, needs full ft Begin mowing at approximately 0.180 inch These grasses are well suited for portions of the transition zone and farther south and their use will only continue to grow. "Sunday outperformed TifEagle in cool season color, height of cut, and green speeds and has two-thirds more root mass," said Easter. If new course, insist on the best.

Mini Verde Bermudagrass has many of the same great benefits as all of the other bermuda grasses. coverage of the surface with individual grass sprigs Leaves 10.2 mm long and 1.14 mm wide. (particularly deep and aggressive) may create an 25F (minus 5C). vertical cutting. poor playing surface during periods of stress (i.e. One activity that golf courses undertake on greens is a process called "Verticutting". The benefits of applying growth regulators include improved shade and drought tolerance, and reduced top growth which improves playability. yd. media. Use particle SGN (size Backtrack verticutting is most effective and keep in mind that verticutting down grain will be the most aggressive direction. Call Us 803.263.4231. Mini Verde green is also important. aeration. Each type of greens construction requires different water If a thatch layer, develop above the soil, making them more susceptible to All Rights Reserved. Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. Richardson, M., and J. Booth. high The first pass should be made in the most aggressive direction (down grain) and the second in the opposite direction, but on the same pass. There is no one-size-fits all program for ultradwarf management, but these practices are fundamental to produce high-quality surfaces for 49 weeks of the year allowing a few weeks for the necessary disruption of aeration. B. TifEagle is encouraged to review these suggested TifEagle is a very fine-textured dwarf bermudagrass, tolerant of 3mm mowing height and uniquely adapted to intensively managed golf greens in the Southern Hemisphere. Consult the mowers. sub-tropical climates. A. Remove aerification cores and debris. A mechanical sand rake or comparable machine combined with wetting of the surface is suggested as a means to compact the sprigbed. drought-tolerant and disease-resistant. contours. For instance, ammonium sulfate has been shown to exacerbate mini-ring symptoms but can help reduce severity of spring dead spot. It would be wrong to characterize ultradwarfs as being low-maintenance grasses, but they can deliver good results across the budget spectrum as long as maintenance resources match expectations. dense mat of washed turf. With its unique growth habit, Emerald Dwarf Bermudagrass creates a tight, firm putting surface with very little grain. Controlling nematodes on the perimeter of the within the layer, and poor Several morphological characteristics give TifEagle its unique advantages: $ excellent root system development and structure$ high quality putting surfaces at cutting heights of 0.125" and lower$ rhizomatous rather than stoloniferous growth habit$ superior color under cool conditions$ tolerance to verticutting$ rapid regrowth from mechanical injury. The recommended mat layer thickness This means mowing a pass across the green, then turning around and mowing the opposite direction over the same pass. aerification, and/or use of a hydrojet can lessen these Root-infecting diseases such as pythium root rot and spring dead spot infect the turf in fall, but the symptoms arent apparent until winter or spring when the turf is under stress. TifEagle Management. B.Walk-behind mowers provide an optimum surface practices. The following bullets outline the backtrack verticutting process: Mow the putting green. TifEagle putting greens have been overseeded with Poa trivialis since 1994. In the past, a lot of golf coursesused Bentgrass. Stimpmeter measured putting speed was 8.5 at the beginning and near 10 ft. at the end of the test period. Benefits | Research Data | TifEagle Sales | Golf Course Installations The video shows you a proven method to remove thatch in a Tif-Eagle putting green. Mowing is fundamental to provide a high-quality putting surface and having sharp and properly adjusted mowers is critical. cool conditions fertility and growth patterns of the grass. Research has shown that inadequate maintenance of Backtrack verticut the green. vegetation. Caution: Since plant growth regulators usually lessen Practices such as mowing, topdressing, light verticutting, applying plant growth regulators (PGRs) and water management are some of the most critical components of a successful ultradwarf management program. Planting rate is similar to Tifdwarf.At least 80% of the putting surface should be uniformly covered with grass sprigs. Thus, TifEagle is not recommended for collars.
