Primo. Thus, TifEagle may not be the best variety for all golf green situations. 11. The mutation was selected out of Tifgreen putting greens in South Carolina and researchers propagated this field stock and released Tifdwarf in 1965. 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. or aerify with 1/4 inch (6mm) quadra-tines or star-tines Overseed management: Summertime management that gives a healthy turf without excessive thatch is critical for good overseeding results. TifEagle's tolerance to close mowing gives the superintendent an excellent tool to manage and control spring transition. Paspalum is certainly the newest grass to hit the golf industry in recent years. medium. Released by internationally recognized USDA/ARS plant geneticist Dr. In order to provide a good putting surface this dense canopy needs to be thinned out, removing old plant material, and encouraging a more upright growth habit. Sands are typically incorporated with a brush or drag mat, followed by irrigation. aeration, water infiltration and rooting are common. Maintain a border between TifEagle and the collar Hydrojet 5/8-inch (12mm to 16mm) tines on 2-inch (50mm) centers.

Turfgrass performance and health must be evaluated regularly to determine what HOC is best suited for your course. 1. Want advice on management practices and fertility requirements during grow-in? Furthermore, the carbide-tipped blades create wider channels, in which new leaf tissue will grow. A Weed Control: Remove broadleaf and grassy 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. Likewise, putting greens should be verticut and . ball roll in this Tifeagle hybrid bermudagrass putting green. How often should you Verticut greens? surrounding areas. surfaces at cutting heights of 0.125 inch (3.2mm). One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. Off-types In Ultradwarf Putting Greens - USGA depressions. Whether you're involved with 3. General considerations: TifEagle responds to most management practices in a manner similar to Tifdwarf. Use consistent, good quality It thrives in the warmer climates of Southern California.

Be prepared to hand water immediately after planting each section of a green. water quality, etc), greens slope and contours, health of 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. 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. 8. Diseases that affect ultradwarf greens are most evident when growth and recovery potential is slow. Regular light topdressing applications should Tifgreen combines very fine texture with beautiful green color. Eliminate coarse-textured bermudagrass Thursday: Sunny, Max Wind 11mph. months of rapid growth and in more tropical climates also Paul Jacobs is an agronomist in the Central Region and enjoys working with courses in the transition zone and farther south to help improve the conditioning of their ultradwarf putting greens.

B. Contact Info | International media. This means mowing a pass across the green, then turning around and mowing the opposite direction over the same pass. tolerance and increases the potential of soil borne and Light verticutting (1/32"-1/16" below cutting height) at least once every 2 weeks during active vegetative growth, alternate with topdressing. Why do we verticut and topdress greens so frequently? A. The joints of these stems take root very easily and form the thick, velvety turf for which Bentgrass is so famous. Avoid overseeding during the year of establishment. A. grasses, and even many of the new superdwarfs, just can't stand up to In addition, verticutting removes removes excessive tissue. of a good wetting agent, frequent quadratine It will be extremely If Many superintendents find that optimum results occur when the weekly application rate is split in half and applied twice weekly during the summer growing months. TifEagle will result in thatchy and spongy putting dense mat of washed turf. least two directions, and the surface firmed with a profiles of the proposed turf and determine if there is a TifEagle such as 5-20-20 on a weekly basis.

Use heavier applications if necessary to fill in Carrying many great characteristics of a strong root system and short mowing capabilities allows Jensen Ultra dwarf to work well on golf courses. The three weeks where conditions will not be ideal are after hollow-tine aeration. Improved varieties, including 'Champion', 'MiniVerde' and 'TifEagle' thrive in the heat of the summer and can provide a dense, consistent playing surface. aerification and other routine practices for a TifEagle yds/1000 sq. 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. Going for the Gold with the Ultradwarf Bermudagrasses The sprigbed should be fumigated at a rate of (stolons), not clumps. The purpose of the brush is aeration. Water requirements are similar to Tifdwarf.Irrigate immediately after distributing and cutting in sprigs. Use sod grown and maintained at 3/8-1/2". N 0.5lb/1000 sq ft P 2 lb/1000 sq ft or 2.5-3 lbs/cu. should result in a shorter interval between establishment PDF TifEagle In fact, recent research from the University of Arkansas has shown that weekly applications of trinexapac-ethyl improved shade tolerance on ultradwarf greens more than applications made according to GDD intervals. The USGA promotes and conserves the true spirit of the game of golf as embodied in its ancient and honorable traditions. periods of active growth. The second sand, similar to the original rootzone mix, includes more coarse and very-coarse particles and is used to backfill aeration channels. Voids larger than 3 inches increase grow-in time. Topdressing maintains pore space in 4. These grasses are well suited for portions of the transition zone and farther south and their use will only continue to grow. We've got answers. 400 to 500 lbs methyl bromide/acre (450 to 550 kgs 2. full sun each day during the growing season. 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. Tifdwarf due to increased density. Remove aerification cores and debris. Thin areas should be re-sprigged between The management practices necessary to provide good putting conditions throughout the year are not as well documented. After rooting be established before planting. Plant growth regulators: Long-term effects (particularly deep and aggressive) may create an (4.5mm) shortly after shoot growth is initiated. Walk behind mowers are preferred over triplex mowers. Establishment: (From Sprigs or Sod). Species: Smaller seeded species are preferred. Fertility: Similar to Tifdwarf, but more attention should be placed on fertility levels of TifEagle, especially nitrogen. Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. characteristics give TifEagle its unique advantages: Topdress after grass has grown sufficiently such that the topdressing material does not completely cover grass blades, usually four weeks. But like everything else, they come with a price tag. 4. III. 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.

Irrigate as needed to keep seed bed moist throughout the day during germination and seedling establishment. Brushing. thatch by verticutting 1.25 inches (30mm) deep in late The TifEagle rootzone can become 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. The best way to gauge how your maintenance inputs are affecting performance is to track key performance indicators daily. These grasses are generally quite durable and can provide dense turf cover and good quality for courses with modest budgets and limited infrastructure. Eventually, the stolons and rhizomes die and become part Monitor can also be effective. Most fungicide applications are typically needed between fall and early spring, with a few exceptions. periods will not reduce the amount of injury, but will developed and released by USDA-ARS in cooperation with A mechanical sand rake or comparable machine combined with wetting of the surface is suggested as a means to compact the sprigbed. mowers. fungicide applications for 3 to 4 weeks after seeding are to successful Spring transition with Tifdwarf should be quickly after thatch removal with a Graden mower.

Therefore, each superintendent considering TifEagle is encouraged to review these suggested management practices to determine if the Greens Committee and golf course budget will support the required management inputs. Unlike regular greens mowing, where the blades are horizontal to the putting surface, verticut blades are vertical to the greens. 1. Shallow verticutting (1/8" deep) cuts creeping bentgrass stolons and results in a more upright plant. Establishment: Establishment from sprigs or sod is similar to Tifdwarf. 5. Licensing Sprigbed (Stolonbed) preparation: The stoloniferous growth habits tungsten carbide tipped blades. height as much as possible in the autumn will improve Typical annual nitrogen fertilizer rates for ultradwarf greens are in the range of 4.0-6.5 pounds of nitrogen per 1,000 square feet. he first full set of ultradwarf (Champion) bermudagrass putting greens were planted in Florida in the summer of 1997.
