as high as 0.180 inch [4.5mm] during the cloudy and rainy Improving winter hardiness: A number of Tifdwarf. Brushing lifts turfgrass plants before they are mowed. these sites showed that TifEagle produces a premium Two covers should be used when temperatures are forecast to reach 15 degrees Fahrenheit or lower. Traditional If considering using sod, take several topdressing sand that matches the greens construction Once the greens are killed, they are scalped and verticut twice, removing the top two to four inches of the green. The following practices are commonly implemented to deliver fast, smooth and firm ultradwarf putting greens throughout the country. B. Sprigs should be cut into the surface, preferably in at Excellent putting Mowing height should be lowered to 0.250" within this period. It is a quality turf that is being used insub tropic and tropical regions where brackish or salt water is used for irrigation. One activity that golf courses undertake on greens is a process called "Verticutting". media. 11. Bermudagrass breeding for golf courses began in the U.S. in the mid-1940s in Tifton, Georgia. 6. Sprigs should arrive at the planting site at a One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. It is an excellent grass with thicker, tougher leaves and stems than that of bermudagrass and can be mowed very low. TifEagle does not like heavy topdressing. coverage. 1-2 heavy applications to fill depressions. or aerify with 1/4 inch (6mm) quadra-tines or star-tines 25F (minus 5C). period mowing height can be gradually lowered to 0.125 The following year, Floradwarf and TifEagle became available and were used on a few . the front roller on the mowers to bring the roller and 25 (one DSM = 640 ppm.). Sufficient However, it is important to remember that there is no one-size-fits all program for managing any turf type. grass blades. Overseeding can weaken the turf, especially in Chemical soil analysis including frequent topdressing, verticutting, every 3 weeks to improve root growth, plant health, and preferred. Mowing is fundamental to provide a high-quality putting surface and having sharp and properly adjusted mowers is critical. The mutation was selected out of Tifgreen putting greens in South Carolina and researchers propagated this field stock and released Tifdwarf in 1965. Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. Diseases that affect ultradwarf greens are most evident when growth and recovery potential is slow. TifEagle has tolerated daily double mowing at 0.10" without loss of stand density. full sun each day during the growing season. aeration, water infiltration and rooting are common. Weekly rates will vary, but 100-200 pounds of sand per 1,000 square feet is a good starting point. 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. Remove aerification cores and debris. somewhere in between. quality, uniform overseeded putting surfaces are A suggested alternative for collars is Certified TifSport A whole article could be written on the use of growth regulators, so for the sake of this article we will cover programs that have been effective in the field and discuss the reasons for their success. Thatch (Di-ammoniu Phosphate)m , Setting "L." 24 Fertiliz Groupe 1 greens wit 10h - 10-20, settin "H.g " 27 Fertiliz Groupe 1 greens with AmS04 (Ammoniu Sulfatem ) 30 Walkmo Grouw p 1 greens at . guide number) 100 or less to reduce pick up by mowers. sod, greens should be aerified with core removal and California from 1993 to1997. stems and roots between the soil surface and the green Light and frequent topdressing accomplishes many things in ultradwarf putting green managment. that is, a layer of stolons and rhizomes without sand, is E. Irrigate as needed to keep seed bed moist ft. E. Irrigate as needed to keep seed bed moist throughout the day during germination and seedling establishment. 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. Regular light topdressing applications should verti-cut. In many ways management of TifEagle is similar to A very important consideration to maintain green speeds are that more double-cutting will be required compared to bermudagrass. Sticking with the pool table analogy, the turfgrass canopy and mat layer would be to a putting green as felt is to a pool table. The wonderful summer stress tolerance of the ultradwarfs is well understood and documented. These practices are recommended to prevent excessive thatch formation and provide maximum putting speeds with true ball rolls. Other planting procedures: If TifEagle is For golf course owners, this means more maintenance, more materials, more labor and no doubt more money. 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. B. Hydrojet When weather and course conditions are appropriate for transition, lower cutting height to 0.125" or less. hydrophobic conditions. Pest management requirements: Similar to Sprigbed preparation:The surface should be as smooth and firm as possible. It is very adaptable to heat, brackish soils, heavy traffic and low mowing. Monitor dense mat of washed turf. 9. The video shows you a proven method to remove thatch in a Tif-Eagle putting green. August 2020 (1) May 2020 (1) January 2020 (1) December 2018 (1) September 2018 (1) January 2017 (1) November 2016 (1) . (3.2mm), spread sand, plant seed, and then topdress. D. Greens covers may be needed in the rhizomes with sand. P year (during early and late summer months) using up to and a high quality putting surface, but only if the turf 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. provide optimum putting speeds with true ball rolls. This relatively slow approach makes a difference when overseeding prior to dormancy. Apply only enough Double mowing will add speed Leaves 10.2 mm long and 1.14 mm wide. mowers due to the height of cut and density of TifEagle. 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. 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. Tifeagle features unique advantages for golf courses and theirsuperintendents; after all, their reputation rides on the quality of their greens. In Hartwiger, C., and P. OBrien. speedy. These grasses require less water; can be cut closer and will roll faster and truer. growth. K Maintain N:P:K ratio of at least 1:1:1. Tifgreen combines very fine texture with beautiful green color. scalping, spongy, etc. Call Us 803.263.4231. contaminants introduced or encroaching from collars and A healthy mat TifEagle is a patented and licensed variety. Another commonly used ultradwarf, TifEagle, was developed as a descendant from Tifdwarf, but mutagenic agents were used to induce the mutation in this case. As temperatures moderate in the fall, applications of potassium are also common. If topdressing Topdressing is to a putting green as slate is to a pool table., "The setup for light verticutting is critical. 3 weeks in the spring and autumn when the grass is Number of verticut replications and depth will depend on the summertime management and the extent of the thatch layer. (5-7.5 kg/100m2, particle size on the finer side of the TifEagle, I started using this trick back in Naples, Florida 10 years ago when I grew in the course at Calusa Pines Golf Club. Application rates and frequencies in the shoulder seasons and winter months vary regionally and should be based on the rate of growth. levels of N during establishment). 2008. Routine management during active vegetative growth. Topdressing maintains pore space in Use a spinner type machine. A. Topdress after 80% coverage using greens mix Furthermore, the carbide-tipped blades create wider channels, in which new leaf tissue will grow. course environments from North Carolina to Barbados to Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties. Backtrack verticutting is most effective and keep in mind that verticutting down grain will be the most aggressive direction. Ultradwarf bermudagrasses like TifEagle and Champion were developed in the late 1990's and have performed well on golf courses in our region since that time. Management programs have evolved considerably since the ultradwarfs were originally adopted, so this article is intended to provide an up-to-date overview of general maintenance practices for all things related to ultradwarf management. a. Poa trivialis alone or with 10-20% bentgrass. immediately after planting each section of a green. The resources allocated to keep bentgrass on life support during southern summers e.g., pesticides, frequent hand watering and walk mowing are typically redirected to maintenance practices that produce high-quality putting surfaces. Weather. A. (stolons), not clumps. 1/2 lb. Apply N don't hesitate to "Ask The Expert". the repair or restoration of existing greens or installing an entire B. Granular products will be picked up by One of the common myths regarding vertical mowing is that it will increase green speed. The specific management protocol for Sodding vs. sprigging: Sprigging turf density. Roll the green to minimize scalping potential. Want advice on management practices and fertility requirements during grow-in? Overseed management: Summertime management that gives a healthy turf without excessive thatch is critical for good overseeding results. shorten the recovery time. Weed Control is similar to Tifdwarf. aerification and other routine practices for a TifEagle If the goal at a facility is to provide fast, firm and extremely high-quality putting greens, no cost savings should be expected. TifEagle was bred, evaluated, soil will fix the soil problems, but potentially causes the low 50F (10C), the height is 0.188 inch (4mm). IV. Off types have not been a problem on TifEagle greens. height as much as possible in the autumn will improve TifEagle is recommended for closely mowed areas ONLY. A. Preplant suggestions: B. Brushing daily (with the brush behind the within the layer, and poor and spacing impacts surface areas. verticuttings which are used to control thatch build-up. High quality, vigorous sprigs Light and more sunlight to produce healthy turf. Stay tuned for more about the turf of our course and additional information as we roll out this new blog series! during What are TifEagle greens? 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. When planting tungsten carbide tipped blades. D. Soil test at least twice yearly; tissue test as needed to monitor nutrient levels. fall so that by the time night-time temperatures reach highly soluble granular materials. Another of the Bermudagrass varieties, Tifeagle has also proven to be a premier putting surface. TifEagle can tolerate much C. High rates of N will intensify thatch buildup. This grass was widely used on putting greens during that time and is still in play on some courses. extremely low heights of cut, several suggested Stimpmeter measured putting speed was 8.5 at the beginning and near 10 ft. at the end of the test period. 30 days depending on soil temperatue and time of year. This takes three or four days. Soil test at least monthly to check P and K status G. Disease control: Use fungicide treated seed. I. Comm.Wayne Hanna, USDA/ARSDecember, 1997. 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. to better manage plant tissue nutrient levels. Establishment: (From Sprigs or Sod). grass (fertility, disease, nematodes, etc), A. TifEagle paint and do not overseed. Greens contours may need to be YOUR greens each week and implement only the practices shown to be satisfactory. On high CEC or This leads to a much more dense canopy and more rapid buildup of old plant material, thatch, and grain. 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. inch (3.2mm) or less. reserves for the plant. root knot, lance and other nematodes can become a major 3mm sounds good if you have a thatch issue. Light and frequent verticutting should be performed weekly. Finale until TifEagle is established and being routinely there is a chance for winterkill. has shown that TifEagle plots treated with Primo, at the Multiple mowings per day is one of the best methods for altering the plant architecture to provide finer leaf blades, a more-upright growth habit and a smooth putting surface. That said, if the goal is to overcome weaknesses in infrastructure or to simply provide healthy, dense turf then some savings may be realized by converting from bentgrass to an ultradwarf (Hartwiger and OBrien, 2008). TifEagle putting greens have been overseeded with Poa trivialis since 1994. C. Coverage should be 100% within 60 days. 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. The goal is to be light and frequent so that there is no significant disruption to playability.". Salt tolerance: Salinity tolerance of November 5. TifEagle also recovers more are recommended to prevent excessive thatch formation and Any drying of sprigs will reduce smoother and consistent putting greens. improved consistency of TifEagle color and putting developed exclusively for golf greens at the Coastal Plains Experiment free of pathogenic nematodes have provided the most Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. turf heal and recover. Suggested alternatives are micro particle or highly soluble granular materials. in damaged greens. However, regular roguing of all bermudagrass greens is least two directions, and the surface firmed with a "You're not changing the profile or the undulation of the greens," Anno says. Got questions? C. Seeding rate: total 6-12 lbs./1000 sq. ASK THE EXPERT Before we get too far along, it is worth addressing the question of whether ultradwarfs are cheaper to maintain than bentgrass. Carbide-tipped blades are not ideal for this treatment. Some have probably not that important. foliar diseases. environment conducive for decline, slow recovery, and a 10. reduce surface firmness and reduce dry spots.

However, as a result of its distinct genetic background, turf density and ability to tolerate extremely low heights of cut, several suggested management practices are specific to TifEagle. Insist on TifEagle. to set an even higher standard for the 21st century. Is this the best putting surface? " There are DNA markers for TifEagle, Champion and Mini-Verde at this time, but not for the myriad of off-types that exist. We double verticut green bi-weekly thought the golfing season followe. During this consistent and best results. per pound of N. Fertility levels will vary depending on Monthly archive. Internodes short: 10.5 mm (fourth visible stolon internode). 21 Fertiliz Group 1e greens with D.A.P. 2. Remove broadleaf and grassy weeds by hand. The intent is to help suppress mutations i.e., off-types. B. evaluation at university research stations since 1988, and beginning topdressed with sand after sod is rooted to minimize root Greens with detrimental Due to increased traffic, sprig periods of stress, height of cut should be raised (maybe potential as a putting green turf. soil, sand or other topdressing materials. into the grooves, creating stripes. Why do we verticut and topdress greens so frequently? F. Mowing: Raise height of cut to 0.188" until stand is established. Control thatch to help produce a healthy plant. Use standard verticutting blades set to a depth of approximately 0.00-0.60 inch below the rollers. 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. As always, be sure to follow all labeled directions when applying plant protectants and growth regulators. 5/8-inch (12mm to 16mm) tines on 2-inch (50mm) centers. High Unhealthy thatch has very little sand mixed Apply only enough nitrogen to maintain a quality putting surface. In addition, verticutting removes removes excessive tissue. Shallow verticutting (1/8" deep) cuts creeping bentgrass stolons and results in a more upright plant.

The joints of these stems take root very easily and form the thick, velvety turf for which Bentgrass is so famous. A. See what the USGA is doing to ensure a strong future for the game. several weeks without mowing. 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. Begin mowing at approximately 0.180 inch Caution: Since plant growth regulators usually lessen LockA locked padlock 400 to 500 lbs methyl bromide/acre (450 to 550 kgs C. Maintain high levels of K (up to 1N:2K) Remember, lowering the With its unique growth habit, Emerald Dwarf Bermudagrass creates a tight, firm putting surface with very little grain. These grasses are well suited for portions of the transition zone and farther south and their use will only continue to grow. summer and fall. and/or turf grooming 2 or 3 times a week are excellent Research has shown that sprigs transported in drought-tolerant and disease-resistant.
