“…Another bentgrass species, velvet bentgrass, is often used in place of creeping bentgrass as a golf course turf in cool, moist, oceanic climates found predominantly in New England and the Pacifi c Northwest (Christians 1998;Turgeon 1996). Velvet bentgrasses are prostrate, stoloniferous grasses whose fi ne leaf texture and high shoot density lead to a lush, velvet-like appearance (DeFrance et al, 1952;Sprague and Evaul, 1930). Recently, there has been increased interest in using velvet bentgrass outside of these areas as researchers have noted excellent heat, drought, and low temperature tolerance relative to creeping bentgrass (Beard 1973;Brilman and Meyer 2000).…”

The tolerance of velvet bentgrass (Agrostis canina L.) to the herbicide fenoxaprop is not known. In greenhouse experiments velvet bentgrass cultivars SR7200 and Vesper had a much greater degree of tolerance to fenoxaprop at rates ranging from 0.01 to 0.30 kg·ha-1 relative to L-93 creeping bentgrass (Agrostis stolonifera L.). SR7200 and Vesper were tolerant to fenoxaprop at 0.15 kg·ha-1 or lower and growth reductions did not exceed 10% at the highest fenoxaprop rate of 0.30 kg·ha-1. In contrast, growth reduction of L-93 creeping bentgrass was evident at the lowest application of fenoxaprop at 0.01 kg·ha-1 and increased as fenoxaprop rates increased, reaching as high 58% at 0.30 kg·ha-1. Field experiments were conducted in 2002 and 2003 to compare the tolerance of established SR7200 velvet bentgrass and Penn A-4 creeping bentgrass maintained at 3.2 mm to three sequential applications at 21 day intervals of fenoxaprop at 0.02, 0.04, and 0.07 kg·ha-1. Turf quality of SR7200 was equal to the untreated following all fenoxaprop applications except the third sequential application at 0.07 kg·ha-1. Penn A-4 turf quality was consistently reduced compared to the untreated following fenoxaprop applications of 0.04 and 0.07 kg·ha-1. Turf density of SR7200 was not affected by three sequential applications of fenoxaprop at 0.02 and 0.04 kg·ha-1 but was reduced by 8% at 0.07 kg·ha-1. Penn A-4 turf density was reduced by 10 and 33% following three sequential applications of fenoxaprop at 0.04 and 0.07 kg·ha-1, respectively. Results from these studies showed that the velvet bentgrass cultivars were more tolerant to fenoxaprop, compared to the creeping bentgrass cultivars evaluated. Chemical names used: (+)-ethyl2-[4-[(6-chloro-2-benzoxazolyl)oxy]p henoxy] propanoate (fenoxaprop). 3,5-pyridinedicarbothioic acid, 2-(difluoromethyl)-4-(2-methylpropyl)-6-(trifluoromethyl)-S,S-dimethylester (dithiopyr).

“…After being brought to North America in the 1900s, New England golf superintendents realized that velvet bentgrass produced beautiful putting greens like a "velvet carpet." (DeFrance et al, 1952). It has high resistance to dollar spot (Sclerotinia homoeocarpa F.T.…”

Thatch Control in Newly Established Velvet Bentgrass Putting Greens in Scandinavia

The use of velvet bentgrass (Agrostis canina L.) on putting greens is limited by sparse knowledge on optimal maintenance. Our objective was to determine the effects of N (75 or 150 kg N ha−1 yr−1), topdressing (0.5 or 1.0 mm biweekly), and mechanical‐biological treatment (grooming, vertical cutting, spiking, and Thatch‐less) on turfgrass visual quality, playability, winter survival, and thatch formation. The study was conducted at a coastal location in Norway (Landvik, 58°N) from August 2007 to May 2010 on sand‐based root zone (United States Golf Association specifications) seeded in late spring 2007 with velvet bentgrass ‘Legendary’. Only the higher N rate gave acceptable quality during the first 2 yr after sowing. The higher N rate reduced moss and winter injuries from disease compared with the lower N but decreased surface hardness by 21% and reduced ball roll distance by 6 to 14%. Significant interactions reflected an increase in mat organic matter with increasing N rate under light but not under heavy topdressing. Compared with grooming only, grooming plus vertical cutting significantly reduced mat organic matter from 64 to 53 g kg−1. Grooming plus spiking improved water infiltration rate by 51% compared with grooming alone. Thatch‐less increased hardness of the otherwise soft plots receiving grooming plus spiking but had no effect on mat depth or organic matter content.

“…Recently velvet bentgrass has been found to maintain acceptable quality in low-input golf course fairways subjected to two mowing heights and three levels of traffic (Watkins et al, 2010). However, establishment and management practices for this species have not been extensively studied and the limited research has focused primarily on older varieties of velvet bentgrass selected from South German mixed bentgrasses (DeFrance et al, 1952;North and Odland, 1934;Skogley, 1975;Sprague and Evaul, 1930).…”

Velvet Bentgrass and Creeping Bentgrass Growth, Rooting, and Quality with Different Root Zone Media and Fertility Regimes

Two complementary greenhouse studies were conducted to examine the effects of different root zones and fertilization regimes on ‘SR7200' velvet bentgrass (Agrostis canina L.) and L-93 creeping bentgrass (Agrostis stolonifera L.). In the first study, in which only velvet bentgrass was studied, peat content in the root zone mixture contributed significantly to initial establishment of this species and high seeding rates increased cumulative shoot dry weight early in establishment but became less significant as the turfgrass matured. Higher phosphorus rates contributed to increased cumulative shoot dry weight over the first 4 weeks of the experiment. Nitrogen rate was the most significant factor positively affecting both cumulative shoot dry weight and turfgrass quality. In the second experiment with both velvet bentgrass and creeping bentgrass, nitrogen rate significantly increased turfgrass quality when measured at Week 5, halfway through the experiment. Over time, however, turf growth and quality were negatively impacted in both species with increasing nitrogen rates. Root zone composition had a significant effect on initial establishment of both bentgrasses with greater peat content leading to higher quality early on. Cumulative shoot dry weight increased with increasing nitrogen rate but at higher rates, there was a concomitant decrease in root production.
