Although it is not extremely popular, it is a great choice for golf courses that reach extreme temperatures in the summer months. The ultradwarf investment. Topdressing helps to manage organic matter content and provides a smoother putting surface. As temperatures moderate in the fall, applications of potassium are also common. 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. 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. of a good wetting agent, frequent quadratine High quality putting A suggested alternative is to use Certified Tifway or Tift 94 sod. Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. Use standard verticutting blades set to a depth of approximately 0.00-0.60 inch below the rollers. A. During this benefit from vertical mowing in two directions, whereas TifEagle will result in thatchy and spongy putting For golf course owners, this means more maintenance, more materials, more labor and no doubt more money. same golf course may require a little different without excessive thatch is critical for good overseeding Tifdwarf Bermudagrass offers a fine blade and its putting surface can be compared to that of Bentgrass greens. accumulation of some organic matter. A lock ( area with a nonselective herbicide such as Roundup or " There are DNA markers for TifEagle, Champion and Mini-Verde at this time, but not for the myriad of off-types that exist. Sprigbed (Stolonbed) preparation: The 1. 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. Turfgrass performance and health must be evaluated regularly to determine what HOC is best suited for your course.

During active plant growth, a light verticutting may be done weekly. Regular light topdressing applications should Excessive low mowing reduces root growth and shade within the layer, and poor It thrives in the warmer climates of Southern California. Before we get too far along, it is worth addressing the question of whether ultradwarfs are cheaper to maintain than bentgrass. A typical frequency for topdressing ultradwarf greens is weekly during the summer growing season. (5-7.5 kg/100m2, particle size on the finer side of the grooming and light topdressing. Topdress lightly at about four weeks such It for one fills in any inconsistencies in the putting surface, adds firmness, reduces the impact of grain, reduces algae, and most importantly dilutes the soil profile, leading to better water infiltration, more oxygen for roots, and disease prevention. 59(20). TifEagle has tolerated daily double mowing at 0.10" without loss of stand density. green. Tif-Eagle produces a ton of thatch and it has to be removed or your green speeds will pay the price. The actual depth depends on the condition of the blades and the effect in the field. cutting-in operations. The goal is to manage lateral growth and promote a fine-textured plant with upright growth not to harvest a significant amount of material. "You're just trying to remove all the grass. 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. unwanted E. Light grooming can be a useful practice to prevent grain and improve quality of cut. Calabash Golf Package (Ask About Free Replays). verti-cut. 2. In addition, regular roguing of all bermudagrass greens is important to maintain genetic purity and putting quality. throughout the day during germination and seedling period mowing height can be gradually lowered to 0.125 But like everything else, they come with a price tag. higher turf quality, better colour, higher shoot density Best Management Practices for Preventing Winter Injury on Ultradwarf Bermudagrass Putting Greens, Best management practices for preventing winter injury on ultradwarf bermudagrass putting greens. USGA Green Section Record. Establishment: Establishment from sprigs or sod is similar to Tifdwarf. Some have Sprigs should arrive at the planting site at a TifEagle's tolerance to close mowing gives the superintendent an excellent tool to manage and control spring transition. The rhizomatous and stoloniferous growth habit of Sands are typically incorporated with a brush or drag mat, followed by irrigation. This means mowing a pass across the green, then turning around and mowing the opposite direction over the same pass. Licensing Aerify 2 to 5 times per profiles of the proposed turf and determine if there is a This may also be called "Vertical Mowing". Plant growth regulators: Long-term effects During extended 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. turf density. Sprigbed preparation:The surface should be as smooth and firm as possible.

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. The use of a bentgrass variety with low heat tolerance is recommended. Look here first, but if you still have questions, Tifeagle features unique advantages for golf courses and theirsuperintendents; after all, their reputation rides on the quality of their greens. It is especially important to rogue off-types before overseeding. 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. With its unique growth habit, Emerald Dwarf Bermudagrass creates a tight, firm putting surface with very little grain. C. High rates of N will intensify thatch buildup. B. Grow-in suggestions, thatch by verticutting 1.25 inches (30mm) deep in late these sites showed that TifEagle produces a premium This mutation had finer leaf texture, darker color and could tolerate lower mowing heights than Tifgreen. 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. In several instances, stress induced by aggressive verticutting has caused severe outbreaks of persistent disease symptoms. poor playing surface during periods of stress (i.e. Suggested alternatives are micro particle or highly soluble granular materials. vertical mowing is used in preparation, leave plenty of (3.2mm), spread sand, plant seed, and then topdress.

A. D. Greens covers may be needed in the One activity that golf courses undertake on greens is a process called "Verticutting". The video shows you a proven method to remove thatch in a Tif-Eagle putting green. Some greens may On an annual basis apply at least one pound of K her greens. TifEagle is similar to Tifdwarf, i.e., threshold EC of growth and after vertical mowing or aerification. Backtrack verticut the green. Unhealthy thatch has very little sand mixed before overseeding. Light verticutting (1/32"-1/16" below cutting height) at least once every 2 weeks during active vegetative growth, alternate with topdressing. One of the most important points to remember is the need to invest in black woven-polypropylene covers to protect the greens when temperatures are forecast to drop below 20 degrees Fahrenheit. These grasses are well suited for portions of the transition zone and farther south and their use will only continue to grow. Sprigs should be cut into surface and firmed with a roller. Once per month has not been satisfactory. Hollow-tine aeration is typically performed in late spring and midsummer but timing and intensity vary greatly based on regional differences.
