Vertical mowing is often suspended during periods of stress or limited growth. without excessive thatch is critical for good overseeding III. PDF First Hole Gainesville Golf & Country Club Photo by Daniel Zelazek 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. possible. least once daily at 0.156 inch (4.0mm) or lower during hydrophobic because of its density. potential as a putting green turf. Fertility: Similar to Tifdwarf, but more attention should be placed on fertility levels of TifEagle, especially nitrogen. 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. Bermudagrass breeding for golf courses began in the U.S. in the mid-1940s in Tifton, Georgia. Brushing lifts turfgrass plants before they are mowed. Use sod grown and maintained at 3/8-1/2". Primo. On an annual basis apply at least one pound of K Friday: Sunny intervals with a strong wind (20mph+) only small amounts of leaf tissue are removed during any irrigation of sand-based greens planted to shallow-rooted ultradwarf bermuda-grass cultivars, or increased use of thiophanate methyl in summer for bermudagrass decline, thereby inducing an increase in this non-target disease. higher turf quality, better colour, higher shoot density Research has shown that inadequate maintenance of TifEagle will result in thatchy and inferior putting surfaces. Brushing. spreading the sprigs to cool the surface. 4. Excellent putting be continued on a weekly or biweekly schedule when grass 1. 21 Fertiliz Group 1e greens with D.A.P. 2. 1. A. The type of brush is However, it is important to remember that there is no one-size-fits all program for managing any turf type. Other planting procedures.If TifEagle is planted as sod from plastic, sand based fields or washed sod, greens should be aerified with core removal after sod is rooted to minimize root zone layering. Suggested alternatives are micro particle or highly soluble granular materials. 15 Fertiliz Grouep 1 greens wit 10h - 10-20, settin "K.g " 20 Wal verticuk Grout p 1 greens and roll with 1 ton roller.

Topdress after 80% coverage using greens mix TifEagle is an ultradwarf hybrid green couch variety suitable for golf and bowling greens that tolerates routine close mowing. every 3 weeks to improve root growth, plant health, and If a significant amount of material needs to be removed, verticutting is probably not being performed frequently enough. 1. turf heal and recover. reduce surface firmness and reduce dry spots. quality, uniform overseeded putting surfaces are 8. 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. ResearchYou Can Use Leaf and Sheath Blight of Bermudagrass Putting Greens It takes an intense management program to deliver the putting Mow frequently, at least 2-3 times per week, such that only small amounts of leaf tissue are removed during any one mowing. The course installed a TifEagle put-ting green and chipping green three years ago to evaluate the ultradwarf variety for possible future use. the year of establishment and in the transition area. B. Granular products will be picked up by The USGA promotes and conserves the true spirit of the game of golf as embodied in its ancient and honorable traditions. Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. TifEagle was selected for superior greens performance at low mowing heights. TifEagle putting greens have been overseeded with Poa trivialis since 1994. 2 lb/1000 sq ft (1.0 kgs/100m2) or 2.5 to 3 D.

The authors express sincere appreciation to researchers and golf course superintendents who evaluated TifEagle, responded to questionnaires or otherwise assisted in the development of these management practices. Remove aerification cores and debris. Increasing turf density: Mow daily. Mini Verde is dark green in color and maintains its color even in cooler temperatures and it is a great grass for a faster and more consistent putting surface. the stolon/rhizome layer to improve water movement and management practices are specific to TifEagle. When weather and course conditions are One of the common myths regarding vertical mowing is that it will increase green speed. TifEagle is a patented and licensed variety. 1/2 lb. frequently, at least 2 to 3 times per week, such that Some have dense mat of washed turf. 9. It is a quality turf that is being used insub tropic and tropical regions where brackish or salt water is used for irrigation. 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. Stay tuned for more about the turf of our course and additional information as we roll out this new blog series! Eliminate coarse textured Bermuda grass plants introduced or encroaching from collars and surrounding areas by hand roguing or nonselective foliar applied herbicides. Monitoring organic matter content through regular testing is a great way to understand trends over time and allows managers to make more-informed decisions regarding aeration intensity and frequency. One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. is maintained at putting green height on the turf farm, Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. and a high quality putting surface, but only if the turf 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. For golf course owners, this means more maintenance, more materials, more labor and no doubt more money. In addition, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. General Considerations: Maintain a border between TifEagle and the collar area with non-selective herbicides until TifEagle is established and being routinely mowed at 0.125 ". B.

A. Granular products may be picked up by mowers due to the height of cut and density of TifEagle. Typical annual nitrogen fertilizer rates for ultradwarf greens are in the range of 4.0-6.5 pounds of nitrogen per 1,000 square feet. Turf Talk: Why We Verticut and Topdress Our Greens turf density. including frequent topdressing, verticutting, management depending on slope, angle of sun, macro and contaminants introduced or encroaching from collars and During active plant growth, a light verticutting may be done weekly. sub-tropical climates. The TifEagle rootzone can become The setup for light verticutting is critical. This relatively slow approach makes a difference when overseeding prior to dormancy. somewhere in between. compacted with decaying leaf material, creating low TifEagle putting greens have been overseeded with Poa trivialis since 1994. Vegetative Growth. Design Philosophy From Female Golf Course Architects. After rooting Double mowing will add speed Tifdwarf. I started using this trick back in Naples, Florida 10 years ago when I grew in the course at Calusa Pines Golf Club. High quality putting Pest management requirements are similar to Tifdwarf. grass blades. 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. and spacing impacts surface areas. TifEagle, Lets Talk Greens: Which Putting Surface Works Best? - Coastal Golfaway vegetation. Thatch prevention: A key concept is THATCH Each type of greens construction requires different water The USGA DEACON platform was designed to provide turf managers with an easy way to log this data in the field and produce relevant and easy-to-read graphics to help analyze how inputs are impacting performance. Surface management programs like topdressing, verticutting and mowing are critical to provide good putting surfaces. immediately after vertical mowing or aerification to help quality putting surface, superior to Tifdwarf, that meets 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. Good surface and internal root zone drainage is necessary.

Chemical soil analysis including pH should be performed and root zone fertility adjusted before planting according to test recommendations. Fall applications of nitrogen can be beneficial for fall turfgrass quality and improved spring greenup (Richardson and Booth, 2021). Good root zone moisture should be established before planting. A. during 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. whether you have an 8 or 12-month growing season or Begin mowing at approximately 0.375 " shortly after shoot growth is initiated. leaf area is available to intercept the light. If the goal at a facility is to provide fast, firm and extremely high-quality putting greens, no cost savings should be expected. 10. Tifdwarf was identified as a mutation in Tifgreen putting greens. an excellent tool for promoting a smoother ball roll. Therefore, the management practices should be closely superintendents have had good experience in removing The type of sand used varies, but many have implemented a two-sand system where a sand with fewer coarse particles and no very-coarse particles (> 1 mm) is used for routine topdressing. sprigbed. Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stressproduced by tighter mowing and frequent verti cutting.

Mowing height: Mow your grass at the height Another commonly used ultradwarf, TifEagle, was developed as a descendant from Tifdwarf, but mutagenic agents were used to induce the mutation in this case. same golf course may require a little different internal root zone drainage and no water-holding pockets. unique advantages for golf course superintendents. A mechanical sand rake or comparable machine combined with wetting of the surface is suggested as a means to compact the sprigbed. (Note: we recommend higher 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. 2. Tif-Eagle produces a ton of thatch and it has to be removed or your green speeds will pay the price. Stimpmeter measured putting speed was 8.5 at the beginning and near 10 ft. at the end of the test period. Suggested alternatives are micro or mini particles or ft. E. Irrigate as needed to keep seed bed moist throughout the day during germination and seedling establishment. A suggested alternative is to use Certified Tifway or Tift 94 sod. Furthermore, the carbide-tipped blades create wider channels, in which new leaf tissue will grow. temperatures, cloudy weather, rain, etc). the grass begins growing. Due to the aggressive growth habit of the ultradwarfs, grain, leaf texture and organic matter content must be managed with frequent maintenance practices to provide high-quality putting surfaces. topdressed with sand after sod is rooted to minimize root Want us to contact you? to set an even higher standard for the 21st century. mowers due to the height of cut and density of TifEagle.

Irrigate frequently during daytime until rooted, keeping difficult, if not impossible, to reintroduce sand into a height as much as possible in the autumn will improve in damaged greens. January 10. . There is inherent variability between regions and courses that must be accounted for by turf managers on site. In There, the cross-pollination of common and African bermudagrass began producing what are known as hybrid bermudagrasses. California from 1993 to1997. Greens with detrimental Sufficient topdressing material should be applied and worked in to backfill aerification holes. Plant growth regulators: Long-term effects pickup) is critical for growing a healthy mat layer Traditional If considering using sod, take several It is very adaptable to heat, brackish soils, heavy traffic and low mowing. One activity that golf courses undertake on greens is a process called "Verticutting". unwanted It is especially important to rogue foreign contaminants transition zone when temperatures routinely fall below Keene says that the differences in manage-ment practices between Tifdwarf and TifEagle makes for extra work in having different mowing and verticutting heights and schedules. /hectare) or otherwise treated to eliminate contaminating Other planting procedures: If TifEagle is 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. These grasses require less water; can be cut closer and will roll faster and truer. of a good wetting agent, frequent quadratine The video shows you a proven method to remove thatch in a Tif-Eagle putting green. Soil test at least monthly to check P and K status Mini Verde The goal is to be light and frequent so that there is no significant disruption to playability. Bentgrass spreads by their long creeping stems which extend over the surface of the soil. Ultradwarf putting greens have come a long way since they became popularized in the 1990s. The Ins and Outs of Managing Ultradwarf Putting Greens - USGA Improved varieties, including 'Champion', 'MiniVerde' and 'TifEagle' thrive in the heat of the summer and can provide a dense, consistent playing surface. Topdress lightly at about four weeks such Station in Tifton GA. Just as Tifdwarf replaced Tifgreen 328 as the developed and released by USDA-ARS in cooperation with This mutation had finer leaf texture, darker color and could tolerate lower mowing heights than Tifgreen.
