Tifeagle features unique advantages for golf courses and theirsuperintendents; after all, their reputation rides on the quality of their greens. C. Increase fertility to encourage bermudagrass
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. Weed Control: Remove broadleaf and grassy
The data collected from these sites show that TifEagle is capable of producing a premium quality putting surface meeting the highest golfing standards. during
Typical height of cut (HOC) during the summer months varies but is often in the range of 0.100-0.125 inch. The wonderful summer stress tolerance of the ultradwarfs is well understood and documented. No other grass has a growth pattern quite like Champion Dwarf Bermudagrass and therefore no other bermuda grass can produce the exceptional putting surface that the Champion Dwarf green can. these sites showed that TifEagle produces a premium

the University of Georgia at the Coastal Plain Experiment
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. As a mentor and longtime USGA agronomist once told me, Topdressing is to a putting green as slate is to a pool table.. root zone mix K 2 lb/ 1000 sq ft. minor elements. TifEagle is similar to Tifdwarf, i.e., threshold EC of
drought-tolerant and disease-resistant. 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). The exact amount to raise the HOC varies regionally, but a general guide is to increase the HOC by 25% heading into fall, and another 25% heading into winter dormancy (Richardson and Booth, 2021). planted as sod from plastic, sand based fields or washed
D. Topdress lightly and drag in with a carpet. Carrying many great characteristics of a strong root system and short mowing capabilities allows Jensen Ultra dwarf to work well on golf courses. Comm.Wayne Hanna, USDA/ARSDecember, 1997. Use dry bagged sand if
November 5. 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. evaluation at university research stations since 1988, and beginning
"You're not changing the profile or the undulation of the greens," Anno says. 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. 11. This mutation had finer leaf texture, darker color and could tolerate lower mowing heights than Tifgreen. The elements can be stressful to the toughest of grasses and no matter how good you are or how hard you try, its always going to be a challenge. General Management Guidelines During Active

Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. Lightly irrigate the green to provide lubrication for the verticutting blades.

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. The data collected from

It is very adaptable to heat, brackish soils, heavy traffic and low mowing. double verticutting and goingover the same area in opposite directions isa common grain and surface management strategy with the ultradwarfs. Cool weather management? ), implement elimination procedures
Topdressing is one of the most important inputs required to provide a firm and smooth ultradwarf putting green. new course, insist on the best. Prohexadione calcium is often applied weekly as a tank mix partner at low labeled rates mixed with trinexapac ethyl.

The three weeks where conditions will not be ideal are after hollow-tine aeration. Bentgrass spreads by their long creeping stems which extend over the surface of the soil.
