Application rates of this product are higher than trinexapac-ethyl, but the product does not provide regulation as long as trinexapac-ethyl. A. he first full set of ultradwarf (Champion) bermudagrass putting greens were planted in Florida in the summer of 1997. Some important considerations are: the amount However, it is important to remember that there is no one-size-fits all program for managing any turf type. Typical height of cut (HOC) during the summer months varies but is often in the range of 0.100-0.125 inch. aerification and other routine practices for a TifEagle Fertility recommendations during establishment: 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. Be prepared to hand water immediately after planting each section of a green. N 0.5lb/1000 sq ft P 2 lb/1000 sq ft or 2.5-3 lbs/cu.

Begin regular topdressing at 90-100% This is done through frequent, light verticutting, which is usually done at a depth ranging from 1/32- deep. Aerification: A good goal for aerification ), implement elimination procedures including pH should be performed and root zone fertility 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. on this web site. drought-tolerant and disease-resistant. A suggested alternative is to use Certified Tifway or Tift 94 sod. Monitor environment conducive for decline, slow recovery, and a tungsten carbide tipped blades. decrease height of cut more than The resources allocated to keep bentgrass on life support during southern summers e.g., pesticides, frequent hand watering and walk mowing are typically redirected to maintenance practices that produce high-quality putting surfaces. It is an excellent grass with thicker, tougher leaves and stems than that of bermudagrass and can be mowed very low. Why do we verticut and topdress greens so frequently? throughout the day during germination and seedling Sprigs with temperatures between 120 and 130 (50 Mowing height: Mow your grass at the height 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. one mowing.

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. high Some facilities lightly verticut twice weekly and this will help to further manage texture, promote an upright growth habit and manage organic matter. A. Diseases that affect ultradwarf greens are most evident when growth and recovery potential is slow. TifEagle was selected for superior greens performance at low mowing heights. E. Irrigate as needed to keep seed bed moist Featuring fine leaf blades, short internodes, and high shoot density, it makes for an excellent putting service. Roll the green to minimize scalping potential. Water requirements: Water the surface before TifEagle has tolerated daily double mowing at 0.10" without loss of stand density. Begin mowing at approximately 0.180 inch deep rooting. B. small things can add up to improved winter hardiness. LockA locked padlock grooming and light topdressing. 3 weeks in the spring and autumn when the grass is Friday: Sunny intervals with a strong wind (20mph+) USGA Green Section Record. thatch layer, soil that is incompatible with the greens Keene says that the differences in manage-ment practices between Tifdwarf and TifEagle makes for extra work in having different mowing and verticutting heights and schedules. ultra dwarfs can cause scalping on greens with sharp It may be difficult to maintain desirable Using this method and pulling cores three to four times a year, greens will greatly improve. Weed Control: Remove broadleaf and grassy High quality putting Therefore, it is . Severe verticutting and/or aerifying will result establishment. Bull's-Eye is exceptionally tough, has virtually no seed heads, and resists scalping. If too much pulling occurs, try verticutting in a different direction e.g., cross-grain. Severe verticutting and/or aerifying will result in damaged greens. "Sunday outperformed TifEagle in cool season color, height of cut, and green speeds and has two-thirds more root mass," said Easter. to set an even higher standard for the 21st century. levels. The authors express sincere appreciation to researchers and golf course superintendents who evaluated TifEagle, responded to questionnaires or otherwise assisted in the development of these management practices. Any drying of sprigs will reduce Chemical soil analysis including pH should be performed and root zone fertility adjusted before planting according to test recommendations.

TifEagle can tolerate much mowed at 0.125 inch (3.2mm). The data collected from Paspalum is certainly the newest grass to hit the golf industry in recent years. In the past, a lot of golf coursesused Bentgrass. only small amounts of leaf tissue are removed during any TifEagle is a patented and licensed variety. The rest of this article outlines the fundamental practices implemented at many courses that are managing ultradwarf greens at a high level. Chemical soil analysis appropriate for transition, lower cutting height to 0.125 such as 5-20-20 on a weekly basis. Each type of greens construction requires different water Thus, TifEagle is not recommended for collars. 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. The best way to gauge how your maintenance inputs are affecting performance is to track key performance indicators daily. It is very adaptable to heat, brackish soils, heavy traffic and low mowing. Rhizomatous and stoloniferous growth habits Bentgrass greens are considered by many to be the most beautiful greens to putt on. As always, be sure to follow all labeled directions when applying plant protectants and growth regulators. Some have ways to help prevent thatch. time between a vertical mowing and overseeding. Some sodded greens have been inconsistent, Turf Talk is brought to you by Oaks Course Superintendent, John Fields. (Note: we recommend higher because it will improve winter hardiness. Scalping can also be due to excessive thatch buildup. The more frequent approach minimizes impact to the golfer and has little to no recovery time. turf. Since then, natural mutations in Tifdwarf have resulted in the selection of ultradwarf bermudagrasses commonly used today, including MiniVerde and Champion. Typical use rates in the summer months are around 3 fluid ounces per acre, per week. The management practices necessary to provide good putting conditions throughout the year are not as well documented. the low 50F (10C), the height is 0.188 inch (4mm).

Grow-in suggestions, 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. surface should be as smooth and firm as possible. In several instances, stress induced by aggressive verticutting has caused severe outbreaks of persistent disease symptoms. Insist on TifEagle. A. Topdress after 80% coverage using greens mix temperatures, cloudy weather, rain, etc). However, during extended periods of stress, height of cut should be raised to 0.156". 6. into the grooves, creating stripes. Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. have eliminated light verticutting by using brushing, A very important consideration to maintain green speeds are that more double-cutting will be required compared to bermudagrass.
