A 4-yr experiment was conducted in southern Florida, on a US Golf Association (USGA)-specified green to examine the effect of topdressing and vertical mowing frequency on ultradwarf bermudgrass cultivars Champion, TifEagle, and FloraDwarf for primarily quality, growth, tissue N and K, and ball roll distance. Diseases that affect ultradwarf greens are most evident when growth and recovery potential is slow. Some of this problem can be solved by reversing
Ultradwarfs can also deliver championship-quality conditions throughout much of the year if the resources are available for consistent surface management throughout the growing season. This leads to our next topic: topdressing. 8. 2023 United States Golf Association. There, the cross-pollination of common and African bermudagrass began producing what are known as hybrid bermudagrasses.

Even among the ultradwarf varieties, there is no other grass that generates the incredible ball roll of a well-maintained Champion Dwarf green.

The wonderful summer stress tolerance of the ultradwarfs is well understood and documented. 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 DEACON platform was designed to provide turf managers with an easy way to log this data in the field and produce relevant and easy-to-read graphics to help analyze how inputs are impacting performance. Water requirements are similar to Tifdwarf.Irrigate immediately after distributing and cutting in sprigs. This is done through frequent, light verticutting, which is usually done at a depth ranging from 1/32- deep. Pest management requirements: Similar to
