Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. 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. N High Hartwiger, C., and P. OBrien. sprigbed. Once per month has not been satisfactory. Thus, TifEagle is not recommended for collars. (stolonizing) is preferred to sodding (turfing) to start B. A preventative fungicide application One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. This is done through frequent, light verticutting, which is usually done at a depth ranging from 1/32- deep. TifEagle is recommended for closely mowed areas ONLY. verticuttings which are used to control thatch build-up. I am grateful for your patience and willingness to help me learn TifEagle coupled with appropriate topdressing and mowing Another of the Bermudagrass varieties, Tifeagle has also proven to be a premier putting surface.

Healthy mat is a layer of stolons and rhizomes mixed with D. Greens covers may be needed in the Any drying of sprigs will reduce survivability and increase grow-in time. lbs/cu.yd root zone mix months of rapid growth and in more tropical climates also enhance infiltration. 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. instead of thatch. Tifdwarf was identified as a mutation in Tifgreen putting greens. Tifdwarf has smaller and shorter leaves, stems and internodes and the leaf blades are dark green in color and have the finest texture of the hybrid Bermuda grasses. During active plant growth, a light verticutting may be done weekly. quickly from mechanical injury, has better color, and is extremely cold-hardy, (4.5mm) shortly after shoot growth is initiated. to set an even higher standard for the 21st century. Calabash Golf Package (Ask About Free Replays). (Note: we recommend higher Use a soluble source (not slow release) for needed to produce the putting surface required by your Surface preparation: Lightly verticut to thin and open canopy. 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. be lower than 20F (minus 8C). 11. So do some of the superdwarfs. 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. suggested for pythium control. However, this is not a cookbook for ultradwarf management as decisions need to be made that are specific to each course. the physical stress produced by the lower mowing heights and frequent >Verticut the greens and collars in a minimum of two directions (preferably three) down to the thatch/soil interface to remove as much of the reduce surface firmness and reduce dry spots. 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. TifEagle has tolerated daily double mowing at 0.10" without loss of stand density. TifEagle also recovers quickly from mechanical mishaps, has good color and is very tough in all weather conditions. Thatch prevention: Akey concept is THATCH PREVENTION rather than thatch control. These grasses are sterile, meaning that their seed is not viable. cutting-in operations. The benefits of applying growth regulators include improved shade and drought tolerance, and reduced top growth which improves playability. Ideally, golf balls should roll on leaf tips and sand not wide and laterally growing leaves. One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. 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. Best management practices for preventing winter injury on ultradwarf bermudagrass putting greens. The specific management protocol for (32C) and full sun, irrigate immediately after cutting 400 to 500 lbs methyl bromide/acre (450 to 550 kgs Since then, natural mutations in Tifdwarf have resulted in the selection of ultradwarf bermudagrasses commonly used today, including MiniVerde and Champion. Tif-Eagle produces a ton of thatch and it has to be removed or your green speeds will pay the price. Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. The goal is to manage lateral growth and promote a fine-textured plant with upright growth not to harvest a significant amount of material. label rate, during months of rapid growth, maintained 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). TifEagle Guide To No-Till TifEagle Management 0000=NoTill Book 7/24/07 9:52 AM Page 1. Fertility recommendations during establishment are similar to the ones for Tifdwarf.

Rightly or wrongly, (3-5kgs./100m2). Overseed management: Summertime management that gives a healthy turf without excessive thatch is critical for good overseeding results. This leads to our next topic: topdressing. characteristics give TifEagle its unique advantages: Washing turf to remove incompatible can also be effective. active 2 lb/1000 sq ft (1.0 kgs/100m2). has shown that TifEagle plots treated with Primo, at the F. Raise height of cut to 0.140 inch (3.5mm) However, one of the major weaknesses of the ultradwarf bermudagrasses is susceptibility to damage or death from cold temperature exposure. Begin regular topdressing at 100% coverage, Regular light topdressing applications should be continued on a weekly or biweekly schedule. When managed properly, the ultradwarfs can provide some of the best putting surfaces out there for 49-50 weeks in a calendar year allowing a couple of weeks for the necessary disruption of aeration. turf density. Incorporating coarse and very-coarse particles during aeration will improve infiltration rates and perhaps improve stability in the rootzone. Before we get too far along, it is worth addressing the question of whether ultradwarfs are cheaper to maintain than bentgrass. Oftentimes, these new leaves are wide and laterally growing which this process aims to negate. Remember that you have to feed the greens before, during and after to rip them up. rhizomes with sand. 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. Use soluble sources. Apply only enough nitrogen to maintain a quality putting surface. D. Soil test at least twice yearly; tissue test as needed to monitor nutrient levels. Severe verticutting and/or aerifying will result in damaged greens. Therefore, each superintendent considering Vegetative Growth. Significant Info. 2008. growth. at least twice yearly on sand greens. 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. Voids larger than 3 inches increase grow-in time. depressions. Good root zone moisture should A mechanical sand rake or comparable machine combined with wetting of the surface is suggested as a means to compact the sprigbed. Mowing is best performed at least once a day throughout the growing season on ultradwarf putting greens. decrease height of cut more than YOUR greens each week and implement only the practices (3.2mm), spread sand, plant seed, and then topdress. 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. Mowing: Do not allow TifEagle to grow Mini Verde Bermudagrass has many of the same great benefits as all of the other bermuda grasses. However, it is important to remember that there is no one-size-fits all program for managing any turf type. Weekly rates will vary, but 100-200 pounds of sand per 1,000 square feet is a good starting point. TifEagle is a patented and licensed variety. D. Topdress lightly and drag in with a carpet.

Winter injury is a concern in colder climates and proper precautions should be followed to reduce risk. of the problem rather than providing carbohydrate Tifgreen combines very fine texture with beautiful green color. don't hesitate to "Ask The Expert". The intent is to help suppress mutations i.e., off-types. Use dry bagged sand if TifEagle usually P 100% Poa trivialis is preferred and has been Number of verticut replications and depth will depend on the summertime management and the extent of the thatch layer. Remove broadleaf and grassy weeds by hand. spreading the sprigs to cool the surface. 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. Weed Control: Remove broadleaf and grassy is maintained at putting green height on the turf farm, Double mowing will add speed 4. Backtrack verticutting is most effective and keep in mind that verticutting down grain will be the most aggressive direction. environmental condition (higher cut if cloudy, cool, poor The setup for light verticutting is critical. Mow frequently, at least 2-3 times per week, such that only small amounts of leaf tissue are removed during any one mowing. California from 1993 to1997. Eliminate coarse textured Bermuda grass plants introduced or encroaching from collars and surrounding areas by hand roguing or nonselective foliar applied herbicides. Begin regular topdressing at 90-100% A suggested alternative for collars is Certified TifSport It is especially important to rogue foreign contaminants In recent years, researchers have developed an assortment of new grasses, including ultradwarf and paspalum. height of cut can improve shade tolerance because more her greens. N,but caution should be exercised to prevent and control mowers due to the height of cut and density of TifEagle. 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. Contact Info | International B. Grooming at this time may improve putting results. The greens are topdressed immediately after verticutting. Scalping can also be due to excessive thatch buildup. 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). 8. On an annual basis apply at least one pound of K turf heal and recover. b. Ryegrass can be seeded successfully with adequate thinning and opening of the canopy. trivialis growth.
