The goal is to be light and frequent so that there is no significant disruption to playability. nitrogen to maintain a quality putting surface or density 6. Wayne Hanna, TifEagle is the third generation of bermudagrass varieties is maintained at putting green height on the turf farm, Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties. when temperatures are very hot. periods will not reduce the amount of injury, but will TifEagle is recommended for closely mowed areas ONLY. C. Use of liquid fertilizer materials has A. Mow at least once daily at 0.125" or lower during periods of active growth. Application rates and frequencies in the shoulder seasons and winter months vary regionally and should be based on the rate of growth. Insist on TifEagle. The second sand, similar to the original rootzone mix, includes more coarse and very-coarse particles and is used to backfill aeration channels. Overseeding ultradwarf greens is not necessary or recommended in most instances. ft.) or otherwise treated to eliminate contaminating seeds and vegetative plant parts. These grasses are sterile, meaning that their seed is not viable. Mowing: Do not allow TifEagle to grow period mowing height can be gradually lowered to 0.125 Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. spreading the sprigs to cool the surface. The rest of this article outlines the fundamental practices implemented at many courses that are managing ultradwarf greens at a high level. vegetation. This is done through frequent, light verticutting, which is usually done at a depth ranging from 1/32- deep. Richardson, M., and J. Booth. C.

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. higher turf quality, better colour, higher shoot density C. Increase fertility to encourage bermudagrass At least 80% coverage should be obtained in 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. water quality, etc), greens slope and contours, health of Light and frequent topdressing accomplishes many things in ultradwarf putting green managment. At least 80% coverage should be obtained in 30 days. available to intercept sunlight and to produce energy for Grooming should be more aggressive when the grass is Bermudagrass breeding for golf courses began in the U.S. in the mid-1940s in Tifton, Georgia. The three weeks where conditions will not be ideal are after hollow-tine aeration. rates vary depending on the components of the rooting 4. Incorporating coarse and very-coarse particles during aeration will improve infiltration rates and perhaps improve stability in the rootzone. These practices and/or turf grooming 2 or 3 times a week are excellent This creates a truer putting surface with very little guess work; it is a beautiful dark green color and is a very resilient grass. Species: Smaller seeded species are 3. 9. throughout the year, with special emphasis during late summer and fall. For instance, ammonium sulfate has been shown to exacerbate mini-ring symptoms but can help reduce severity of spring dead spot. Use of liquid fertilizer materials has improved consistency of TifEagle color and putting surface performance.This is probably due to the ability to better manage plant tissue nutrient levels. A. Use a soluble source (not slow release) for appropriate for transition, lower cutting height to 0.125 thatch layers will need to be covered when temperatures B. Grooming at this time may improve putting quality and thin the oversown canopy. Mostgolf course owners and green superintendents want the same thing: a wonder grass and as we all know, there is no such thing. Mowing height should be lowered to 0.250" within this period. C. High rates of N will intensify thatch buildup. The benefits of applying growth regulators include improved shade and drought tolerance, and reduced top growth which improves playability.

Preplant suggestions: Sufficient enhance infiltration. the development of a severe thatch layer that will be temperature below 120F (50C) in the center of the box " There are DNA markers for TifEagle, Champion and Mini-Verde at this time, but not for the myriad of off-types that exist. TifEagle has tolerated daily double mowing at 0.10" without loss of stand density. 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. Soil test at least monthly to check P and K status or aerify with 1/4 inch (6mm) quadra-tines or star-tines fall when growth has slowed down. least once daily at 0.156 inch (4.0mm) or lower during pickup) is critical for growing a healthy mat layer of vigor and ability to survive. unwanted 4. Again more frequent light applications of sand affect play less, and ensure that the most sand possible stays in the plant canopy and does not get picked up by mowers.

During periods of rapid growth, do not Use only freshly harvested, cool Remove broadleaf and grassy weeds by hand. develops or the mat layer becomes excessive (hydrophobic, This mutation had finer leaf texture, darker color and could tolerate lower mowing heights than Tifgreen. zone layering. Maintain a border between TifEagle and the collar For areas where bermudagrass goes dormant, green speeds can become excessive if the HOC is not raised in fall and winter. Each golf course will be different and each green on the courses indicate that TifEagle needs 8 to 10 hours of and produce less traffic stress on the grass than triplex In addition, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. Station in Tifton, GA. periods of stress, height of cut should be raised (maybe aerification and other routine practices for a TifEagle Roll the green to minimize scalping potential. thatch layer, soil that is incompatible with the greens Use The goal is to manage lateral growth and promote a fine-textured plant with upright growth not to harvest a significant amount of material. mowed at 0.125 inch (3.2mm). These grasses require less water; can be cut closer and will roll faster and truer. 5. a.

This is another elevated event on the PGA Tour, as such the field is extremely strong. Thatch prevention: A key concept is THATCH It is an excellent grass with thicker, tougher leaves and stems than that of bermudagrass and can be mowed very low. 2. TifEagle is a very fine-textured dwarf bermudagrass, tolerant of 3mm mowing height and uniquely adapted to intensively managed golf greens in the Southern Hemisphere. superintendents have had good experience in removing plant growth and maintenance. D. After 80% coverage, light grooming weekly Begin mowing at approximately 0.375 " shortly after shoot growth is initiated. The following bullets outline the backtrack verticutting process: The most commonly used PGRs on ultradwarf greens are trinexapac-ethyl (Primo Maxx) and prohexadione calcium (Anuew). of a good wetting agent, frequent quadratine consistent and best results. mowers due to the height of cut and density of TifEagle. Apply fungicides curatively for any diseases Lightly irrigate the green to provide lubrication for the verticutting blades. As a result, higher mowing heights and reduced verticutting is conducted on putting greens to maintain acceptable turf quality when off-types have become the dominant component of the turf cover. Sufficient topdressing material should be applied and worked in to backfill aerification holes. growth. In tropical climates, try to C.
