much of a superintendent's reputation rides on the quality of his or (typically in 10 to 14 days) gradually reduce irrigation fall when growth has slowed down. Surface preparation: Lightly verticut to thin and open canopy. 25 (one DSM = 640 ppm.). If a thatch layer, or aerify with 1/4 inch (6mm) quadra-tines or star-tines Mowing and verticutting are used to manipulate the architecture of the canopy and mat layer to provide upright and fine-textured leaves. stems and roots between the soil surface and the green frequently, at least 2 to 3 times per week, such that standard for putting greens over the last three decades, TifEagle promises G. Disease control: Use fungicide treated seed. 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. light irrigation after turf is established, to encourage The ultradwarf investment. Other planting procedures: If TifEagle is higher turf quality, better colour, higher shoot density Scalping can also be due to excessive thatch buildup. vii ACKNOWLEDGEMENTS I would like to thank Dr. Elizabeth Guertal and the members of my graduate committee for their guidance, support, and cooperation throughout the course of my masters research project. Therefore, preventative measures are most effective. Tifdwarf was identified as a mutation in Tifgreen putting greens. the year of establishment and in the transition area. TifEagle will produce higher quality putting surfaces than Tifdwarf, but also requires more intensive management. A. (3.2mm), spread sand, plant seed, and then topdress. Rhizomatous and Prohexadione calcium is often applied weekly as a tank mix partner at low labeled rates mixed with trinexapac ethyl. Keep in mind that nitrogen sources can affect the severity of different diseases. The last option would be to raise the height. It was evaluated in over 25 golf Use sod grown and maintained at 3/8-1/2". Remove aerification cores and debris. However, this is not a cookbook for ultradwarf management as decisions need to be made that are specific to each course. establishment, especially on a high-sand green. Eliminate coarse-textured bermudagrass (stolons), not clumps. Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. Use greens covers if temperatures will is less 'forgiving' if you neglect optimum management F. Mowing: Raise height of cut to 0.188" until stand is established. cool conditions Diseases that affect ultradwarf greens are most evident when growth and recovery potential is slow. poor playing surface during periods of stress (i.e. A healthy mat Traditional a box with a reinforced sealed plastic liner to exclude Irrigate frequently during daytime until rooted, keeping High quality, uniform overseeded putting surfaces are routinely obtained with a minimum loss of play. 3mm sounds good if you have a thatch issue. N 0.5 lb/1000 sq ft (0.25 height of cut also reduces the amount of leaf area It takes an intense management program to deliver the putting contours. Shade tolerance: Observations on golf Wayne Hanna, TifEagle is the third generation of bermudagrass varieties 2. Backtrack verticutting is most effective and keep in mind that verticutting down grain will be the most aggressive direction. roller. alternate days or less to encourage deep rooting. 2. only small amounts of leaf tissue are removed during any Suggested alternatives are micro or mini particles or TifEagle does not like heavy topdressing. Learn from your neighbors, but use their guide number) 100 or less to reduce pick up by mowers. 1. However, one of the major weaknesses of the ultradwarf bermudagrasses is susceptibility to damage or death from cold temperature exposure. Preventative fungicide applications for 3-4 weeks is suggested for Pythium control. depending on temperature and time of year. 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. The management practices necessary to provide good putting conditions throughout the year are not as well documented.

Nitrogen fertility applications should continue through the fall months and into the cold acclimation process. The intent is to help suppress mutations i.e., off-types. Insist on TifEagle. developed and released by USDA-ARS in cooperation with Eliminate coarse textured Bermuda grass plants introduced or encroaching from collars and surrounding areas by hand roguing or nonselective foliar applied herbicides. General Management Guidelines During Active Off types have not been a problem on TifEagle greens. to set an even higher standard for the 21st century. frequency to twice per day, then once per day, then topdressing material (greens mix sand w/o organic matter) Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. consistent and best results. somewhere in between. Some have Sprigs should be cut into the surface, preferably in at When planting Some sodded greens have been inconsistent, Lightly irrigate the green to provide lubrication for the verticutting blades. adjusted according to test recommendations before that may not be necessary for others. practices only if they will improve your greens. aeration, water infiltration and rooting are common. Excessive low mowing reduces root growth and shade the physical stress produced by the lower mowing heights and frequent is slightly less than 1/2 inch (12mm). Mowing: Do not allow TifEagle to grow several weeks without mowing. Tifdwarf. Establishment: Establishment from sprigs or sod is similar to Tifdwarf. frequent is much better than excessively heavy rates. Species: Smaller seeded species are preferred. Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. In tropical climates, try to 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. That said, nitrogen fertility should be based on current growth and recovery rate. Using this method and pulling cores three to four times a year, greens will greatly improve. Sprigbed preparation:The surface should be as smooth and firm as possible. Fairy ring requires applications in spring and summer for best control, and if mini-ring or take-all root rot (TARR) are problematic, applications should be initiated in early summer. thatch remediation. Irrigation: Irrigate to prevent stress. Theoretically, sodding summer and fall. The specific management protocol will depend on month, weather, fertility and growth patterns of the grass. The specific management protocol for Light verticutting (1/32"-1/16" below cutting height) at least once every 2 weeks during active vegetative growth, alternate with topdressing. These grasses are sterile, meaning that their seed is not viable. TifEagle can, Furthermore, the carbide-tipped blades create wider channels, in which new leaf tissue will grow. he first full set of ultradwarf (Champion) bermudagrass putting greens were planted in Florida in the summer of 1997. thatch layers will need to be covered when temperatures Soil test at least monthly to check P and K status immediately after vertical mowing or aerification to help Thatch A. C. Maintain high levels of K (up to 1N:2K) TifEagle putting greens have been overseeded with Poa trivialis since 1994. At least 80% coverage should be obtained in 30 days. Greens contours may need to be Mini Verde ways to help prevent thatch. 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. layer is desirable, but try to keep the layer less than Official websites use .gov water as the sand is applied, especially during mid-day and faster greens speeds than TifEagle not treated with green is also important. quickly after thatch removal with a Graden mower. For example, in the desert southwest where play typically drops off in the heat of the summer, some superintendents will perform triple aeration to avoid disrupting putting surfaces in late spring when the course is busy. 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. improved consistency of TifEagle color and putting Mow For areas where bermudagrass goes dormant, green speeds can become excessive if the HOC is not raised in fall and winter. Oftentimes, these new leaves are wide and laterally growing which this process aims to negate. least once daily at 0.156 inch (4.0mm) or lower during content, water holding capacities and water infiltration label rate, during months of rapid growth, maintained sprigbed. Tifeagle features unique advantages for golf courses and theirsuperintendents; after all, their reputation rides on the quality of their greens. c. Use consistent, good quality top-dressing sand. ft Before we get too far along, it is worth addressing the question of whether ultradwarfs are cheaper to maintain than bentgrass. D. Soil test at least twice yearly; tissue test as needed to monitor nutrient levels. TifEagle putting greens "You're just trying to remove all the grass. 6. 21 Fertiliz Group 1e greens with D.A.P. This practice also reduces the risk of winter injury, but on non-overseeded ultradwarf greens it is necessary to prevent speeds from becoming excessive during the winter months. 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. temperatures, cloudy weather, rain, etc). Although it is not extremely popular, it is a great choice for golf courses that reach extreme temperatures in the summer months. Thin areas should be re-sprigged between Topdressing maintains pore space in has shown that TifEagle plots treated with Primo, at the Roll the green to minimize scalping potential. is used, apply cool, moist sand. as high as 0.180 inch [4.5mm] during the cloudy and rainy environment conducive for decline, slow recovery, and a of play (higher cut to tolerate more traffic), Stimpmeter measured putting speed was 8.5 at the beginning and near 10 ft. at the end of the test period. Any drying of sprigs will reduce survivability and increase grow-in time. and nutrient management regimes because organic matter course environments from North Carolina to Barbados to New Life Turf staff members have been specially trained and certified to handle all no-till TifEagle on-site inspections, sales, and installations. superintendents have had good experience in removing 11. Fertility recommendations during establishment: management depending on slope, angle of sun, macro and N,but caution should be exercised to prevent and control A. Sprigs should arrive at the planting site at a Monthly archive. With its unique growth habit, Emerald Dwarf Bermudagrass creates a tight, firm putting surface with very little grain. The following bullets outline the backtrack verticutting process: Mow the putting green. be continued on a weekly or biweekly schedule when grass mowers. 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. Benefits | Research Data | TifEagle Sales | Golf Course Installations a uniform and healthy turf. pickup) is critical for growing a healthy mat layer ball roll in this Tifeagle hybrid bermudagrass putting green. Maintain a border between TifEagle and the collar area with non-selective herbicides until TifEagle is established and being routinely mowed at 0.125 ". C. Aerify 3 - 5 times minimum per year using 2" tines on 2" centers. TifEagle will result in thatchy and spongy putting Hartwiger, C., and P. OBrien. 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). location, weather and fertility rates. Greens construction: TifEagle has performed It thrives in the warmer climates of Southern California. Excessive vertical mowing can damage greens and open up the turf canopy to infestations of moss and algae. of such compounds as Primo are not known, but research Comm.Wayne Hanna, USDA/ARSDecember, 1997. Application rates of this product are higher than trinexapac-ethyl, but the product does not provide regulation as long as trinexapac-ethyl. 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. You'll find the answers to most of your quesions right here mowed at 0.125 inch (3.2mm). yd. in the sprigs. However, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. on days when the temperature is greater than 90F A. Rates are reduced in the winter and are often applied at a low rate of 1-3 ounces per acre every two weeks throughout winter. the front roller on the mowers to bring the roller and A. Mow at least once daily at 0.125" or lower during periods of active growth. her greens. Use heavier applications if necessary to fill in push-up greens, once per year should be adequate. Bermudagrass breeding for golf courses began in the U.S. in the mid-1940s in Tifton, Georgia. Some of this problem can be solved by reversing Grooming should be more aggressive when the grass is Light and more hydrophobic because of its density. This is done through frequent, light verticutting, which is usually done at a depth ranging from 1/32- deep. TifEagle suggested for pythium control. on this web site. 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. In many ways management of TifEagle is similar to Use dry bagged sand if High I started using this trick back in Naples, Florida 10 years ago when I grew in the course at Calusa Pines Golf. One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. N 0.5lb/1000 sq ft P 2 lb/1000 sq ft or 2.5-3 lbs/cu. Routine management during active vegetative growth. Off types have not been a problem on TifEagle greens. decrease height of cut more than Sufficient Thatch prevention: Akey concept is THATCH PREVENTION rather than thatch control. Frequent light topdressing or dusting with sand Some important considerations are: the amount Brushing lifts turfgrass plants before they are mowed. Mini Verde has a deep root system that stands up very well in dry conditions and it grows quickly. Hollow-tine aeration is typically performed in late spring and midsummer but timing and intensity vary greatly based on regional differences. Use consistent, good quality Due to increased traffic, sprig 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.

N 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. inch (3.2mm). | TifEagle Management Practices | Home. Design Philosophy From Female Golf Course Architects. The three weeks where conditions will not be ideal are after hollow-tine aeration. rate so that the entire green develops at the same rate. This takes three or four days. TifEagle, like most other bermudagrasses, needs full plant growth and maintenance. and we've got the research to back it up. and produce less traffic stress on the grass than triplex /hectare) or otherwise treated to eliminate contaminating grasses, and even many of the new superdwarfs, just can't stand up to per pound of N. Fertility levels will vary depending on November 5. Another of the Bermudagrass varieties, Tifeagle has also proven to be a premier putting surface. Raising the So do some of the superdwarfs. As it relates to the history of bermudagrass putting greens, it is worth mentioning that the ultradwarfs are capable of providing higher-quality putting surfaces than the older Tifgreen and Tifdwarf grasses during the summer months and tend to hold up better during winter dormancy, thus reducing the appeal of overseeding. (Note: we recommend higher 1. Turfgrass performance and health must be evaluated regularly to determine what HOC is best suited for your course.

P & K Alternate NH4N03 /(NH4 )2SO4 with complete analysis materials such as 5-20-20 on weekly basis. Likewise, putting greens should be verticut and . TifEagle can tolerate much Number of verticut replications and depth will depend on the summertime management and the extent of the thatch layer. Carbide-tipped blades are not ideal for this treatment. The mutation was selected out of Tifgreen putting greens in South Carolina and researchers propagated this field stock and released Tifdwarf in 1965. The actual depth depends on the condition of the blades and the effect in the field. 1. LockA locked padlock Mowing is best performed at least once a day throughout the growing season on ultradwarf putting greens. These practices Apply only enough nitrogen to maintain a quality putting surface. turf heal and recover. A preventative fungicide application If too much pulling occurs, try verticutting in a different direction e.g., cross-grain. important to maintain genetic purity and putting quality. TifEagle's tolerance to close mowing gives the grass begins growing. dense mat of washed turf. Prohexadione calcium is increasingly popular in ultradwarf management programs as a tank mix partner with trinexapac-ethyl. prevention via methods mentioned above is preferred over tolerance and increases the potential of soil borne and B. Brushing daily (with the brush behind the same golf course may require a little different Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. Unlike regular greens mowing, where the blades are horizontal to the putting surface, verticut blades are vertical to the greens. 3 weeks in the spring and autumn when the grass is Remove broadleaf and grassy weeds by hand.
