Since then, ultradwarf mutations from Tifdwarf such as TifEagle, MiniVerde and Champion have been widely used throughout the southern part of the country.

This aids in incorporation and reduces the amount of large particles that remain on the surface. TifEagle is similar to other bermudagrass varieties in that it requires full sun for optimum growth. vii ACKNOWLEDGEMENTS I would like to thank Dr. Elizabeth Guertal and the members of my graduate committee for their guidance, support, and cooperation throughout the course of my masters research project.

Since then, natural mutations in Tifdwarf have resulted in the selection of ultradwarf bermudagrasses commonly used today, including MiniVerde and Champion.

sprigs. TifEagle putting greens have been overseeded with Poa trivialis since 1994. 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. Thankfully, extensive research has been performed in this area and a summary of best management practices can be found in the USGA article Best Management Practices for Preventing Winter Injury on Ultradwarf Bermudagrass Putting Greens.. vegetation. Use higher rates of N during periods of active

Chemical soil analysis including pH should be performed and root zone fertility adjusted before planting according to test recommendations. Although it is not extremely popular, it is a great choice for golf courses that reach extreme temperatures in the summer months. Thus, TifEagle is not recommended for collars. The management practices necessary to provide good putting conditions throughout the year are not as well documented. Winter injury is a concern in colder climates and proper precautions should be followed to reduce risk. C. Seeding rate: total 6-12 lbs./1000 sq. until stand is established. One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. temperatures, cloudy weather, rain, etc).

Keene says that the differences in manage-ment practices between Tifdwarf and TifEagle makes for extra work in having different mowing and verticutting heights and schedules.
