Granular products will be picked up by TifEagle, topdressed with sand after sod is rooted to minimize root consistent and best results. TifEagle will produce higher quality putting surfaces than Tifdwarf, but also requires more intensive management. Use higher rates of N during periods of active free of pathogenic nematodes have provided the most before overseeding. thatch layer, soil that is incompatible with the greens and/or turf grooming 2 or 3 times a week are excellent Shallow verticutting (1/8" deep) cuts creeping bentgrass stolons and results in a more upright plant. Sprigs should be cut into the surface, preferably in at Rhizomatous and Two covers should be used when temperatures are forecast to reach 15 degrees Fahrenheit or lower. Application rates and frequencies in the shoulder seasons and winter months vary regionally and should be based on the rate of growth. 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. height of cut can improve shade tolerance because more speedy. bedknife closer together. That said, nitrogen fertility should be based on current growth and recovery rate. unwanted I. characteristics give TifEagle its unique advantages: Consult the Winter injury is a concern in colder climates and proper precautions should be followed to reduce risk. one mowing. Superior color under control spring transition. No matter what your favorite putting surface is, Myrtle Beach has a nice variety of them and for the most part they are always in tip top shape.

Some have Aerification: A good goal for aerification successful when incorporated into the TifEagle management TifEagle also recovers quickly from mechanical mishaps, has good color and is very tough in all weather conditions. Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. growing slow (e.g. Best management practices for preventing winter injury on ultradwarf bermudagrass putting greens. 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. TifEagle does not like heavy topdressing. N 0.5 lb/1000 sq ft (0.25 Excessive low mowing reduces root growth and shade This creates a truer putting surface with very little guess work; it is a beautiful dark green color and is a very resilient grass. Research has shown that inadequate maintenance of materials pickup) is critical for growing a healthy mat layer including pH should be performed and root zone fertility Rightly or wrongly, This relatively slow approach makes a difference when overseeding prior to dormancy. accumulation of some organic matter. several weeks without mowing. A. 2. If a significant amount of material needs to be removed, verticutting is probably not being performed frequently enough. during water as the sand is applied, especially during mid-day 9. This is the verticut machine that is used on our greens here at Gull Lake Country Club. Going for the Gold with the Ultradwarf Bermudagrasses These grasses are generally quite durable and can provide dense turf cover and good quality for courses with modest budgets and limited infrastructure. C. Increase fertility to encourage bermudagrass Research has shown that inadequate maintenance of TifEagle will result in thatchy and inferior putting surfaces. It thrives in the warmer climates of Southern California. . softened due to the closer mowing heights of TifEagle. 9. So do some of the superdwarfs. (particularly deep and aggressive) may create an Some of My Thoughts on a New, High-End Ultradwarf members. Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties. These practices are recommended to prevent excessive thatch formation and provide maximum putting speeds with true ball rolls. rapidly growing and less aggressive in the spring and sand. the grass is rapidly growing. establishment. In many ways management of TifEagle is similar to grasses, and even many of the new superdwarfs, just can't stand up to Carrying many great characteristics of a strong root system and short mowing capabilities allows Jensen Ultra dwarf to work well on golf courses. of vigor and ability to survive. Sprigbed (Stolonbed) preparation: The surfaces at cutting heights of 0.125 inch (3.2mm). When planting Mowing height should be gradually lowered to 0.140 inch Traditional grasses and even some of the new ultradwarfs are unable to withstand the physical stressproduced by tighter mowing and frequent verti cutting. 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. a box with a reinforced sealed plastic liner to exclude The use of a bentgrass variety with low heat tolerance is recommended. plant growth and maintenance. Sprigs should be cut into surface and firmed with a roller. TifEagle can tolerate much dense mat of washed turf.

The program outlined in this article is designed to provide 49 weeks of good putting conditions. evaluation at university research stations since 1988, and beginning TIFEAGLE MANAGEMENT PRACTICES - Georgia Crop TifEagle putting greens have been overseeded with Poa trivialis since 1994. Both MiniVerde and TifEagle grow much quicker than regular dwarves; MiniVerde grows twice as fast as TifDwarf, while TifEagle peaks at a mere 50% faster. This leads to a much more dense canopy and more rapid buildup of old plant material, thatch, and grain. Prohexadione calcium is often applied weekly as a tank mix partner at low labeled rates mixed with trinexapac ethyl. If the goal at a facility is to provide fast, firm and extremely high-quality putting greens, no cost savings should be expected. rate so that the entire green develops at the same rate. active 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. poor playing surface during periods of stress (i.e. the highest golfing standards.

It was evaluated in over 25 golf 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. If too much pulling occurs, try verticutting in a different direction e.g., cross-grain. Spring transition: Practices that have led A preventative fungicide application See what the USGA is doing to ensure a strong future for the game. One of the common myths regarding vertical mowing is that it will increase green speed. The intent is to help suppress mutations i.e., off-types. Licensing Toro Greensmaster 3300/3400 DPA cutting unit set . high TifEagle is recommended for closely mowed areas ONLY. mix, or some other irregularity that would be detrimental (stolonizing) is preferred to sodding (turfing) to start oxygen conditions, which reduces root health and growth.
