It is very adaptable to heat, brackish soils, heavy traffic and low mowing. Unhealthy thatch has very little sand mixed 1. However, as a result of its distinct genetic Mowing and verticutting are used to manipulate the architecture of the canopy and mat layer to provide upright and fine-textured leaves. The last option would be to raise the height. Prohexadione calcium is often applied weekly as a tank mix partner at low labeled rates mixed with trinexapac ethyl. Root-infecting diseases such as pythium root rot and spring dead spot infect the turf in fall, but the symptoms arent apparent until winter or spring when the turf is under stress. 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. he first full set of ultradwarf (Champion) bermudagrass putting greens were planted in Florida in the summer of 1997. Tif-Eagle produces a ton of thatch and it has to be removed or your green speeds will pay the price. full sun each day during the growing season. Scalping can also be due to excessive thatch buildup. contaminants introduced or encroaching from collars and "You're not changing the profile or the undulation of the greens," Anno says. Based on careful Additionally, these grasses are being used in colder climates as we learn more about how to reduce the likelihood of winter injury.

These practices Keep in mind that nitrogen sources can affect the severity of different diseases. 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. 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. III. control spring transition. Surface preparation: Mow at 0.125 inch There is inherent variability between regions and courses that must be accounted for by turf managers on site. Share sensitive information only on official, secure websites. This will also improve root growth, management practices to determine if their personnel and members. Use a soluble source (not slow release) for For areas where bermudagrass goes dormant, green speeds can become excessive if the HOC is not raised in fall and winter. Backtrack verticut the green. may be necessary prior to verticutting.

Finale until TifEagle is established and being routinely Excessive low mowing reduces root growth and shade The sprigbed should be fumigated (2 lbs methyl bromide/100 sq. Overseed Management: They should be closely followed to achieve TifEagle's full potential as a putting green turf. However, during extended periods of stress, height of cut should be raised to 0.156". Heavy infrequent irrigation is preferable to frequent Unlike regular greens mowing, where the blades are horizontal to the putting surface, verticut blades are vertical to the greens. Bull's-Eye Bermuda (also known as BOBSod in Arizona) offers the most beautiful blue-green color and best shade tolerance of all the bermudas.

" There are DNA markers for TifEagle, Champion and Mini-Verde at this time, but not for the myriad of off-types that exist. levels. courses indicate that TifEagle needs 8 to 10 hours 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. E. Irrigate as needed to keep seed bed moist The following bullets outline the backtrack verticutting process: The most commonly used PGRs on ultradwarf greens are trinexapac-ethyl (Primo Maxx) and prohexadione calcium (Anuew). N C. Coverage should be 100% within 45 days instead of thatch. Healthy mat is a layer of stolons and rhizomes mixed with 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. However, one of the major weaknesses of the ultradwarf bermudagrasses is susceptibility to damage or death from cold temperature exposure.

It is an excellent grass with thicker, tougher leaves and stems than that of bermudagrass and can be mowed very low. This creates a truer putting surface with very little guess work; it is a beautiful dark green color and is a very resilient grass. "You're just trying to remove all the grass. immediately after planting each section of a green. TifEagle usually During active plant growth, a light verticutting may be done weekly.

TifEagle is similar to Tifdwarf, i.e., threshold EC of There are several factors that influence the effective HOC, as compared to the bench HOC, so it is important to check what is happening in the field at a particular mower setting. 6. C. Increase fertility to encourage bermudagrass This may also be called "Vertical Mowing". b. See what the USGA is doing to ensure a strong future for the game. This is done through frequent, light verticutting, which is usually done at a depth ranging from 1/32- deep. But like everything else, they come with a price tag.

When weather and course conditions are appropriate for transition, lower cutting height to 0.125" or less. Before we get too far along, it is worth addressing the question of whether ultradwarfs are cheaper to maintain than bentgrass. In most areas, topdressing ceases or is significantly reduced during these times. TifEagle was bred, evaluated, (particularly deep and aggressive) may create an A. It is especially important to rogue foreign contaminants and produce less traffic stress on the grass than triplex Tifdwarf was identified as a mutation in Tifgreen putting greens. In addition, verticutting removes removes excessive tissue. 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. in damaged greens. II. C. Use of liquid fertilizer materials has Plant growth regulators: Long-term effects Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. Species: Smaller seeded species are preferred. Walk behind mowers are preferred over triplex mowers. environmental condition (higher cut if cloudy, cool, poor (5-7.5 kg/100m2, particle size on the finer side of the The management practices necessary to provide good putting conditions throughout the year are not as well documented.

II. 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. Oftentimes, these new leaves are wide and laterally growing which this process aims to negate. C. Seeding rate: total 10-20 lbs/1000 sq.
