TURFGRASS INDUSTRY NEWS
A-LIST Adds Creeping Bentgrass to Its List for Approval For decades breeders have worked to improve the quality and performance of turfgrass varieties. Breeding often emphasized the level of fertility and water for optimal growth desired by users.
However, turf managers are having to balance improved variety management practices with environmental dictates. Reduced inputs have become the norm, not the exception, in the world of turfgrass management. Te Alliance for Low Input Sustainable Turf (A-LIST) saw the need to add another species of turfgrass to their trials to help improve their mission of low input and sustainability. Creeping bentgrass cultivars will now be added to A-LIST approvals. Te large number of golf courses that utilize creeping bentgrass on their course has increased the need to provide certification for an additional species. Breeding efforts have greatly improved the ability of disease resistance, heat tolerance, and reduced input requirements of creeping bentgrass. A list of certified varieties that have been proven to be able to meet the mission of the A-LIST through demonstrated trials is listed below. Creeping bentgrass trials will be a part of the trials for A-LIST varieties now and into the future. Certified Creeping Bentgrass Varieties in the A-LIST include: 007XL, 777, Macdonald, Piper, Oakley, Piranha, Diplomacy, Proclamation, Declaration, Spectrum, Match Play, and Luminary.
DLF Super Bents™ Added to A-LIST When Te Alliance for Low Input Sustainable Turf (A-LIST) announced the addition of creeping bentgrass to its list of approved turfgrass species it included three of DLF’s Super Bents™ varieties: 007XL, 777 (Triple Seven), and Macdonald. 007XL is the newest and most genetically advanced creeping bentgrass available today. It cuts the amount of fungicide needed in half, as compared to older bentgrasses, and it provides exceptional resistance to Dollar Spot, Brown Patch, Anthracnose, and Pink and Gray Snow Mold. 777 is a highly refined variety that shows superior performance under heat and wear stress and excellent disease resistance. It is a dependable variety that will perform in a broad range of environments. Macdonald was developed for its high resistance to diseases, specifically Dollar Spot and Brown Patch. It also establishes well, recovers rapidly, and resists Poa annua invasion. DLF is a global seed company owned by Danish grass seed farmers with more than 2,200 employees in 22 countries worldwide.

Mountain View Seeds Announce 3 Bentgrass Varieties Added to A-LIST Piper, Oakley, and Piranha have made the cut and received A-LIST approval in the first round of evaluations. With the approval of these varieties, Centennial also becomes the only A-LIST approved bentgrass blend. Piranha is a new, ultra-dense creeping bentgrass variety developed specifically to tolerate heat and a number of other stressors that destroy most bentgrass. Piranha has excellent resistance to dollar spot as well as brown patch. Named in honor of the original USGA Green Section agronomists, Dr. Charles Piper and Dr. Russell Oakley; Piper and Oakley embody the USGA Green Section's commitment of continued variety development for improved sustainability in golf. Bred by Dr. Stacy Bonos at Rutgers University, Piper and Oakley will provide golf course superintendents with not only the best traits available, but also a connection to the legacy of greatness in golf course agronomy. Centennial bentgrass blend offers the ideal solution for golf and fine turf applications. As a blend, Centennial offers the benefits of genetic biodiversity; providing the best opportunity for success and a safety net against disease and pest issues that can destroy mono stands. Combining two similar varieties ensures a consistent, uniform playing surface that does not show segregation. Piper and Oakley, while genetically quite different, perform almost identically. In the recent NTEP trials, Piper and Oakley performed statistically the same in these critical traits. But being selected from different parents ensures they are stronger together.
SiteOne® Releases New LESCO Low Odor Broadleaf Herbicide SiteOne® Landscape Supply has introduced LESCO Tree- Way LO, a low odor selective herbicide that offers strong weed control power with less odor — benefiting both contractors and customers. Te new control product uses three active ingredients, 2,4-D, MCPA and Dicamba, to provide comprehensive post- emergent control of a variety of hard-to-kill broadleaf weeds such as clover, dandelion, henbit, and plantains. “Contractors know the power of LESCO Tree-Way because they’ve relied on it for years. We know there are sensitive areas where the use of an effective weed control solution with less odor has been a need,” said Kevin Laycock, category director of agronomics at SiteOne. “We are excited to offer Tree-Way LO as a new option on odor-sensitive locations.” Tree-Way LO has been demonstrated through university trials to be an effective solution that can be applied to a variety of warm and cool season grasses. Its low odor formulation, with flexible application rates, allows it to be tank mixed with liquid fertilizers or liquid iron materials.* Tree-Way LO can be used on residential and commercial turfgrass, sod farms, golf courses, sports fields, rights-of-ways, and other non- crop industrial areas like woody brush in non-cropland areas. New LESCO Tree-Way LO is available in several sizes – from a 1-gallon jug, up to a 265-gallon tote, and many sizes in-between. Learn more about LESCO Tree-Way LO at
