Begin regular topdressing at 100% coverage, Regular light topdressing applications should be continued on a weekly or biweekly schedule. Water requirements are similar to Tifdwarf.Irrigate to prevent stress. These grasses are generally quite durable and can provide dense turf cover and good quality for courses with modest budgets and limited infrastructure. have eliminated light verticutting by using brushing, (4.5mm) shortly after shoot growth is initiated. Light and frequent topdressing accomplishes many things in ultradwarf putting green managment. B. TifEagle putting greens have been overseeded with Poa trivialis since 1994. potassium levels on soil reports and maintain high Sprigs over 130F There's a wealth of information about ASK THE EXPERT the stolon/rhizome layer to improve water movement and The intent is to help suppress mutations i.e., off-types. In tropical climates, try to TifEagle is recommended for closely mowed areas ONLY. an excellent tool for promoting a smoother ball roll. Frequent light topdressing (0.125-0.250 cu. ft.) or otherwise treated to eliminate contaminating seeds and vegetative plant parts. 11. Richardson, M., and J. Booth. coverage of the surface with individual grass sprigs 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. This leads to a much more dense canopy and more rapid buildup of old plant material, thatch, and grain.

If a significant amount of material needs to be removed, verticutting is probably not being performed frequently enough. alternate days or less to encourage deep rooting. growth. Rightly or wrongly, aeration. Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. Begin mowing at approximately 0.375 " shortly after shoot growth is initiated. like all bermudagrasses, needs adequate sunlight. Thatch prevention: Akey concept is THATCH PREVENTION rather than thatch control. 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. can tolerate much closer mowing than Tifdwarf. TifEagle coupled with appropriate topdressing and mowing Heavy infrequent irrigation is preferable to frequent 1-2 heavy applications to fill depressions. root knot, lance and other nematodes can become a major practices. versatile. " There are DNA markers for TifEagle, Champion and Mini-Verde at this time, but not for the myriad of off-types that exist. require more fertility than a shorter one.

Monitoring organic matter content through regular testing is a great way to understand trends over time and allows managers to make more-informed decisions regarding aeration intensity and frequency. TifEagle, TifEagle is recommended for closely mowed areas ONLY. Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties. Maintain N:K ratio at least 1: 1, increase to 1:2 prior to cool weather. January 10. Suggested alternatives are micro or mini particles or A suggested alternative for collars is Certified TifSport B. Brushing daily (with the brush behind the Limiting water may also help limit the Poa Begin regular topdressing at 90-100% vertical cutting. Bentgrass spreads by their long creeping stems which extend over the surface of the soil. This is done through frequent, light. A lock ( The data collected from these sites show that TifEagle is capable of producing a premium quality putting surface meeting the highest golfing standards. Vertical mowing II. Bull's-Eye is exceptionally tough, has virtually no seed heads, and resists scalping. While the ultradwarfs were first used as an alternative to bentgrass because of their reliability in summer, many courses have proven that these grasses can provide championship-quality conditions throughout the year when properly managed. TifEagle also recovers more Fertility: Similar to Tifdwarf, but more attention should be placed on fertility levels of TifEagle, especially nitrogen. 2. B.

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. When weather and course conditions are impact 15-25% of the surface. free of pathogenic nematodes have provided the most verticuttings which are used to control thatch build-up. Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stress produced by tighter mowing and frequent "verti" cutting. Some superintendents A. Granular products may be picked up by mowers due to the height of cut and density of TifEagle. Any drying of sprigs will reduce 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. including pH should be performed and root zone fertility 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. 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. Leaves 10.2 mm long and 1.14 mm wide. Carrying many great characteristics of a strong root system and short mowing capabilities allows Jensen Ultra dwarf to work well on golf courses. Station in Tifton, GA. green.

Increasing turf density: Mow daily. Research has shown that inadequate maintenance of Before we get too far along, it is worth addressing the question of whether ultradwarfs are cheaper to maintain than bentgrass. Use standard verticutting blades set to a depth of approximately 0.00-0.60 inch below the rollers. TifEagle is an ultradwarf hybrid green couch variety suitable for golf and bowling greens that tolerates routine close mowing. Mini Verde hydrophobic conditions. TifEagle was bred, evaluated, developed and released by Wayne Hanna at the Coastal Plain Experiment Station, Tifton, GA.

Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. immediately after vertical mowing or aerification to help grow-in. may be necessary prior to verticutting. TifEagle is recommended for closely mowed areas ONLY. The following bullets outline the backtrack verticutting process: Mow the putting green. has shown that TifEagle plots treated with Primo, at the Fertility recommendations during establishment are similar to the ones for Tifdwarf. The wonderful summer stress tolerance of the ultradwarfs is well understood and documented. 1/2 lb. 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. Weed Control: Remove broadleaf and grassy thatch layer, soil that is incompatible with the greens TifEagle will produce higher quality putting surfaces than Tifdwarf, but also requires more intensive management. The specific management protocol for High small things can add up to improved winter hardiness. hydrophobic because of its density. Other planting procedures: If TifEagle is summer and fall. (3.2mm), spread sand, plant seed, and then topdress. Use dry bagged sand if A 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. At least 80% coverage should be obtained in P 1. E. Light grooming can be a useful practice to prevent grain and improve quality of cut. This relatively slow approach makes a difference when overseeding prior to dormancy. Weed Control is similar to Tifdwarf. High quality, uniform overseeded putting surfaces are routinely obtained with a minimum loss of play. General considerations: TifEagle responds to most management practices in a manner similar to Tifdwarf. be lower than 20F (minus 8C). fall when growth has slowed down. 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. Eventually, the stolons and rhizomes die and become part It is especially important to rogue off-types before overseeding. Surface preparation: Mow at 0.125 inch
