![]() Also, sand topdressing was felt to encourage leaf bruising, which decreased turf quality and possibly encouraged disease. Among the most popular verticutting implements on putting greens included the carbide-tipped Dynablades. Potassium was mentioned by most superintendents as an important nutrient.Ĭultivation: Deep verticutting can be injurious to seashore paspalum, and most agreed that aeration was probably more important than surface cultivation practices. Micronutrient spray programs are often employed, with particular emphasis on magnesium and iron. Most superintendents remarked that while less nitrogen may be required by seashore paspalum than bermudagrass, similar fertilizer treatments are required in regards to application frequency. Grooming was discussed as well and one superintendent employs groomers on each of his mowers on a regular basis to decrease thatch production.įertility: Calcium nitrate was once thought to be a popular fertilizer for seashore paspalum, but many different types of fertilizers are applied to maintain good turf quality. Increased mowing on putting greens is necessary to maintain acceptable speeds. ![]() It is necessary to keep mowers sharp to cut the thicker leaves and stems of seashore paspalum and to reduce disease incidence. ![]() Mowing: Much of the discussion concerned mowing heights, which seemed to be similar to bermudagrass and depended upon the standard of each particular golf course. Issues like disease, drought, and micronutrient deficiency can cause sharp declines in turf quality and attending golf course superintendents mentioned that communication should occur quickly and repeatedly to educate golfers when problems occur. While seashore paspalum has notably better turf quality than bermudagrass, it also can get ugly at times. In bermudagrass, dollar spot can be suppressed with additional fertilizer applications but supplemental nitrogen seems to only slightly reduce dollar spot severity in seashore paspalum. Disease control ranged from occasional fungicide treatment to costly preventative fungicide programs, depending upon the standard of the course. Dollar spot is more injurious on seashore paspalum than on bermudagrass and large patch can be a persistent nuisance on seashore paspalum. Several courses also occasionally apply Trimmit (paclobutrazol) with Primo.ĭiseases: Dollar spot and large patch are the most problematic diseases experienced. Rates generally consist of twice as much as those applied to bermudagrass playing surfaces, with 6 to 8 oz/A/wk applied on most putting greens during the growing months, and higher rates on tees and fairways. Plant Growth Regulation: Primo (trinexapac-ethyl) is applied on a regular basis at each of the respective golf courses. Certainly, this update cannot offer an exhaustive review of each course's program, but it is meant to show the highlights of each topic discussed. The meeting provided an open forum for golf course superintendents to discuss management-related issues concerning seashore paspalum in an informal setting. There was a wide range of golf club standards represented as well. Golf courses ranged from newly-planted seashore paspalum to those several years old, and different varieties were represented (SeaDwarf, SeaIsle 1, SeaIsle 2000 & SeaIsle Supreme). ![]() The group consisted of golf course superintendents, assistant superintendents, sales professionals, and others. ![]() By Todd Lowe - USGA Florida Region AgronomistĪ small group of turfgrass professionals from Southwest Florida met on April 3 rd at Forest Glen Country Club to discuss seashore paspalum management on golf courses. ![]()
