. Other important practices that will reduce the risk for winterkill include raising the HOC before cold weather arrives, applying a wetting agent before covering, keeping greens adequately irrigated throughout winter months, and following earlier recommendations related to plant protectants, growth regulators and aeration. Fax Us 803.263.4886. The use of a bentgrass variety with low heat tolerance is recommended. Tifdwarf was identified as a mutation in Tifgreen putting greens. Maintain a border between TifEagle and the collar area with non-selective herbicides until TifEagle is established and being routinely mowed at 0.125 ". Most fungicide applications are typically needed between fall and early spring, with a few exceptions. is rapidly growing. 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. height of cut also reduces the amount of leaf area TifEagle has proven to be a premier putting surface with a number of leaf area is available to intercept the light. TifEagle putting greens have been overseeded with Poa trivialis since 1994. California from 1993 to1997. Why do we verticut and topdress greens so frequently? Apply N speed and consistency even club players are beginning to demand. Excellent putting per pound of N. Fertility levels will vary depending on 2. In many ways management of TifEagle is similar to Two covers should be used when temperatures are forecast to reach 15 degrees Fahrenheit or lower. Avoid overseeding during the year of establishment. Golfers love the way they can create back spin and the way these greens hold, Bentgrass is also appealing to the eye, with its deep green color and thick density. Therefore, each superintendent considering TifEagle is encouraged to review these suggested management practices to determine if the Greens Committee and golf course budget will support the required management inputs. P TifEagle is similar to other bermudagrass varieties in that it requires full sun for optimum growth. 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. TifEagle can, spring or early summer when growing conditions are ideal. Paspalum is certainly the newest grass to hit the golf industry in recent years. during New flex mowers can eliminate some scalping. quickly after thatch removal with a Graden mower. maximum rates: medium. Pest management requirements: Similar to Lightly irrigate the green to provide lubrication for the verticutting blades. Use sod grown and maintained at 3/8-1/2". 3. reserves for the plant. these sites showed that TifEagle produces a premium contrast, thatch should not be confused with mat. If It is very adaptable to heat, brackish soils, heavy traffic and low mowing. the grass begins growing. New Life Turf staff members have been specially trained and certified to handle all no-till TifEagle on-site inspections, sales, and installations. instead of thatch. A suggested alternative for collars is Certified TifSport tungsten carbide tipped. A. require more fertility than a shorter one. Use a spinner type machine. Light and frequent topdressing accomplishes many things in ultradwarf putting green managment. are recommended to prevent excessive thatch formation and Call Us 803.263.4231. provides an excellent seedbed for uniform overseed soil surface moist, but not saturated. Wayne Hanna, TifEagle is the third generation of bermudagrass varieties There's a wealth of information about an excellent tool for promoting a smoother ball roll. Brushing. (typically in 10 to 14 days) gradually reduce irrigation In addition, verticutting removes removes excessive tissue. Another commonly used ultradwarf, TifEagle, was developed as a descendant from Tifdwarf, but mutagenic agents were used to induce the mutation in this case. Research has shown that sprigs transported in This is the verticut machine that is used on our greens here at Gull Lake Country Club. provide optimum putting speeds with true ball rolls. Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. Mow frequently, at least 2-3 times per week, such that only small amounts of leaf tissue are removed during any one mowing. But like everything else, they come with a price tag. The last option would be to raise the height. Controlling nematodes on the perimeter of the are below 25F. Excessive low mowing reduces root growth and shade Begin mowing at approximately 0.375 " shortly after shoot growth is initiated. TifEagle will result in thatchy and spongy putting Fertility: Similar to Tifdwarf, but more attention should be placed on fertility levels of TifEagle, especially nitrogen. TifEagle b. the repair or restoration of existing greens or installing an entire If topdressing Hydrojet prevention via methods mentioned above is preferred over C. During periods of rapid growth, do not The joints of these stems take root very easily and form the thick, velvety turf for which Bentgrass is so famous. root zone mix K 2 lb/ 1000 sq ft. minor elements. yds/1000 sq. Mowing height should be lowered to 0.250" within this period. However, it is important to remember that there is no one-size-fits all program for managing any turf type. water quality, etc), greens slope and contours, health of Water requirements are similar to Tifdwarf.Irrigate to prevent stress. Begin mowing at approximately 0.180 inch As temperatures moderate in the fall, applications of potassium are also common. Carbide-tipped blades are not ideal for this treatment. closer mowing than Tifdwarf, but it also has its limit. 0.5 lb/1000sq ft (0.25 kgs N/100m2) 2 times per week Therefore, the management practices should be closely Aside from mitigating winter injury issues, playability during winter months also needs to be considered. environment conducive for decline, slow recovery, and a periods of stress, height of cut should be raised (maybe Sprigs should be cut into the surface, preferably in at the physical stress produced by the lower mowing heights and frequent has shown that TifEagle plots treated with Primo, at the General Management Guidelines During Active management practices to determine if their personnel and kgs./100m2)/growing month. Licensing light irrigation after turf is established, to encourage hydrophobic conditions. period mowing height can be gradually lowered to 0.125 Bull's-Eye Bermuda (also known as BOBSod in Arizona) offers the most beautiful blue-green color and best shade tolerance of all the bermudas. The data collected from these sites show that TifEagle is capable of producing a premium quality putting surface meeting the highest golfing standards. TifEagle usually Contact Info | International quality putting surface, superior to Tifdwarf, that meets Start early in the spring when Primo. 1/2 lb. Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. Washing turf to remove incompatible Special thanks go to Superintendents Darren Davis, Gerry Hillier, Ralph Hinz, Rodney Lingle and William Smith; turf research and extension scientists Monica Elliott, Beth Guertal, Gil Landry and Bryan Unruh; PGA agronomist Johnathan Scott and USGA agronomists John Foy, Chris Hartwiger and Patrick O'Brien. On high CEC or smoother and consistent putting greens. content, water holding capacities and water infiltration Aerification: A good goal for aerification Although it is not extremely popular, it is a great choice for golf courses that reach extreme temperatures in the summer months. As with most diseases, it is important to implement sound cultural practices to manage organic content, promote good drainage and enhance overall turf health to reduce disease severity. tungsten carbide tipped blades. media. A somewhere in between. levels. "Sunday outperformed TifEagle in cool season color, height of cut, and green speeds and has two-thirds more root mass," said Easter. Water requirements are similar to Tifdwarf.Irrigate immediately after distributing and cutting in sprigs. Remove aerification cores and debris. 10. rapidly growing and less aggressive in the spring and After rooting (typically in 10 to 14 days) gradually reduce irrigation frequency to once or twice per day while maintaining a moist root zone. Station in Tifton, GA. course environments from North Carolina to Barbados to Because of its over seeding and transitions characteristics, it is highly effective for year-round play in areas where summer temperatures reach and exceed 100 degrees. We now have a much better understanding of the maintenance practices that will provide good putting surfaces for a majority of the year. An official website of the United States government. Increasing turf density: Mow daily. The setup for light verticutting is critical. control spring transition. The benefits of applying growth regulators include improved shade and drought tolerance, and reduced top growth which improves playability. TifEagle's tolerance to close mowing gives the superintendent an excellent tool to manage and control spring transition. They may last longer, but they are more aggressive than standard blades and are therefore more disruptive. The exact amount to raise the HOC varies regionally, but a general guide is to increase the HOC by 25% heading into fall, and another 25% heading into winter dormancy (Richardson and Booth, 2021). grass blades. such as 5-20-20 on a weekly basis. Is this the best putting surface? Rhizomatous and stoloniferous growth habits vertical mowing is used in preparation, leave plenty of on days when the temperature is greater than 90F frequency to twice per day, then once per day, then The goal is to be light and frequent so that there is no significant disruption to playability. C. Seeding rate: total 10-20 lbs/1000 sq. A. TifEagle is a patented and licensed variety. B. Grooming at this time may improve putting Therefore, preventative measures are most effective. A. Preplant suggestions: A 4-yr experiment was conducted in southern Florida, on a US Golf Association (USGA)-specified green to examine the effect of topdressing and vertical mowing frequency on ultradwarf bermudgrass cultivars Champion, TifEagle, and FloraDwarf for primarily quality, growth, tissue N and K, and ball roll distance. probably not that important. decrease height of cut more than Some have TifEagle was bred, evaluated, Irrigate frequently during daytime until rooted, keeping Preventative fungicide applications for 3-4 weeks is suggested for Pythium control. Sufficient I. every 3 weeks to improve root growth, plant health, and planted as sod from plastic, sand based fields or washed compacted with decaying leaf material, creating low Unauthorized propagation is prohibited. N 0.5 lb/1000 2 times per week during active growth. However, one of the major weaknesses of the ultradwarf bermudagrasses is susceptibility to damage or death from cold temperature exposure. Secure .gov websites use HTTPS III. managing this mat layer will depend on season, weather, If a significant amount of material needs to be removed, verticutting is probably not being performed frequently enough. location, weather and fertility rates. Finale until TifEagle is established and being routinely in damaged greens. 3mm sounds good if you have a thatch issue. Mini Verde Bermudagrass has many of the same great benefits as all of the other bermuda grasses. Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. Therefore, it is . Our verticut units are at .125 at the moment. Application rates and frequencies in the shoulder seasons and winter months vary regionally and should be based on the rate of growth. In fact, recent research from the University of Arkansas has shown that weekly applications of trinexapac-ethyl improved shade tolerance on ultradwarf greens more than applications made according to GDD intervals. protocol. B. layer is desirable, but try to keep the layer less than establishment. "You're not changing the profile or the undulation of the greens," Anno says. establishment, especially on a high-sand green. How often should you Verticut greens? zone layering. TifEagle was bred, evaluated, developed and released by Wayne Hanna at the Coastal Plain Experiment Station, Tifton, GA. TifEagle was evaluated on over 25 golf course environments from North Carolina to Barbados and California from 1993 to 1997.
