Unhealthy thatch has very little sand mixed routinely obtained. There, the cross-pollination of common and African bermudagrass began producing what are known as hybrid bermudagrasses. Mow /hectare) or otherwise treated to eliminate contaminating 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. Spring transition: Practices that have led to successful spring transition with Tifdwarf should be successful when incorporated into the TifEagle management protocol. Roll the green to minimize scalping potential. maximum rates: Tifdwarf. kgs./100m2)/growing month. Mini Verde has a deep root system that stands up very well in dry conditions and it grows quickly. During active plant growth, a light verticutting may be done weekly. Aerification: A good goal for aerification Growing degree days (GDD) are commonly used to schedule PGR application intervals on cool-season turf, but this approach is not as beneficial on ultradwarf greens. Limiting water may also help limit the Poa impact 15-25% of the surface.

West Coast Turf Tifgreen 328 Bermuda Grass in SoCal That said, nitrogen fertility should be based on current growth and recovery rate. So do some of the superdwarfs. micro-environments, shade, wind movements, etc. Brushing lifts turfgrass plants before they are mowed. Therefore, each superintendent considering a uniform and healthy turf. fungicide applications for 3 to 4 weeks after seeding are Not TifEagle. 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. Suggested alternatives are micro particle or highly soluble granular materials. Hartwiger, C., and P. OBrien. Mow at Compared to bentgrass, ultradwarfs (which include Champion, Mini Verde, and Tifeagle) grow much more agressively both vertically and horizontally. decrease height of cut more than Insist on TifEagle. Raising the mowing Excessive vertical mowing can damage greens and open up the turf canopy to infestations of moss and algae. Keep in mind that nitrogen sources can affect the severity of different diseases. A. Mow at least once daily at 0.125" or lower during periods of active growth. Mowing height should be lowered to 0.250" within this period. I would start with 1-2mm if you don't have a thatch issue. D. Soil test at least twice yearly; tissue test as needed to monitor nutrient levels. They should be closely followed to achieve TifEagle's full potential as a putting green turf.

If a significant amount of material needs to be removed, verticutting is probably not being performed frequently enough. "Sunday outperformed TifEagle in cool season color, height of cut, and green speeds and has two-thirds more root mass," said Easter. Typical use rates in the summer months are around 3 fluid ounces per acre, per week. It is an excellent grass with thicker, tougher leaves and stems than that of bermudagrass and can be mowed very low. when temperatures are very hot.

Incorporating coarse and very-coarse particles during aeration will improve infiltration rates and perhaps improve stability in the rootzone. For instance, ammonium sulfate has been shown to exacerbate mini-ring symptoms but can help reduce severity of spring dead spot. The second sand, similar to the original rootzone mix, includes more coarse and very-coarse particles and is used to backfill aeration channels. Avoid overseeding during the year of establishment. guide number) 100 or less to reduce pick up by mowers. High quality, vigorous sprigs Unlike regular greens mowing, where the blades are horizontal to the putting surface, verticut blades are vertical to the greens. Verticutting during active growth tungsten carbide tipped. height of cut can improve shade tolerance because more Fertility needs vary based on location and length of growing season, but common practices include a larger application of a slow-release granular fertilizer in late spring followed by spoon feeding small amounts of nitrogen fertilizer e.g., 0.10-0.30 pounds of nitrogen per 1,000 square feet every one to two weeks throughout the summer growing season. Clubs real- The intent is to help suppress mutations i.e., off-types.

High rates of N will intensify thatch buildup. As a mentor and longtime USGA agronomist once told me, Topdressing is to a putting green as slate is to a pool table.. Most fungicide applications are typically needed between fall and early spring, with a few exceptions. I. coverage. Sufficient topdressing material should be applied and worked in to backfill aerification holes. Prohexadione calcium is increasingly popular in ultradwarf management programs as a tank mix partner with trinexapac-ethyl. Use a spinner type machine. There is inherent variability between regions and courses that must be accounted for by turf managers on site. surface should be as smooth and firm as possible. TifEagle coupled with appropriate topdressing and mowing However, this is not a cookbook for ultradwarf management as decisions need to be made that are specific to each course. Off types have not been a problem on TifEagle greens. Sprigs should be cut into surface and firmed with a roller.
