New seed blend for golf greens

New seed blend for golf greens: Germinal has introduced a new seed mixture to its Grade ‘A’ portfolio of golf-specific grass blends: containing two top-performing perennial ryegrasses and a high-ranking creeping bentgrass, A8 Ultrafine Ryegreens is the perfect ‘rescue’ mixture for the eradication of early season scarring.

A8 Ultrafine Ryegreens contains a blend of three of the very best cultivars: 45% Cabrio (ultrafine perennial ryegrass), 45% Escapade (perennial ryegrass) and 10% 007 DSB (creeping bentgrass).

Conceived specifically for greenkeepers who want to overseed their golf greens with a blend containing ryegrasses, the new mixture produces an exceptionally fine-leaved sward which is tolerant of low cutting heights (down to 3mm). It also delivers rapid germination and establishment in cooler conditions and boasts the added advantages of good disease resistance and excellent winter colour.

Cabrio was first introduced as a new cultivar in 2016 and went straight to the top of the BSPB’s Table L1 in 2017 with a fineness of leaf score of 8.8. It subsequently retained this position in 2018 (8.8) and 2019 (8.7) and holds the top spot again in 2020 thanks to another score of 8.7: a rating which puts it half a point clear of its nearest rivals at 8.2. Cabrio also ranks highly on Table G4 (perennial ryegrasses mown at 4-7mm) where it’s 8.4 score for fineness of leaf is the highest.

Escapade also boasts exceptional fineness of leaf (8.1 in Table L1) and offers superb resistance to Red Thread (6.1). It also displays excellent shoot density (7.7) and visual merit (7.6) as well as strong winter and summer greenness scores (5.8 and 6.0 respectively).

Meanwhile, 007 DSB, which was bred in the US using 24 parent plants to produce a single cultivar with a prostrate growth habit, high shoot density and good wear tolerance in a wide range of climatic conditions, has won plaudits wherever it has been used including at Ryder Cup and US Open courses and at the PGA Masters at Wentworth.

“By combining two top-performing perennial ryegrasses with a modern ‘superbent’, A8 Ultrafine Ryegreens creates a contemporary blend of seeds which is suitable for all greens renovation works, but especially when making good damaged areas: the ryegrasses provide initial rapid cover but will not persist in the long-term once cutting heights are consistently lower than 4mm – but by then their job will have been done and the creeping bentgrass will take over,” explains Richard Brown, Germinal Amenity Sales Manager.

“Cabrio is still the number one choice for greenkeepers who want to produce an exceptionally fine-leaved, hard wearing and aesthetically attractive sward that can not only tolerate a close mowing regime, but which will also give good ball roll or bounce. Similarly, Escapade provides added sward resilience, whilst the addition of 007 DSB, which has a lower water and nutrient requirement than older creeping bent varieties, is the ideal companion as it adds useful sward density to complement the bunched growth habits of Cabrio and Escapade.”

A8 Ultrafine Ryegreens is suitable for cutting down to a height of 3mm and has a recommended sowing rate of 20g/m2 (200kgs/ha) and overseeding rate of 10-15g/m2 (100-150kgs/ha). It is also suitable for sowing and overseeding tees and collars.

Barenbrug’s New Winter Sports Blend

Barenbrug’s New Winter Sports Blend: Elite Sport from Barenbrug is the new number one rated Winter Sports blend. The top-performing product blends perennial ryegrasses for the renovation and construction of winter sports pitches.

Cultivar trials at the Sports Turf Research Institute (STRI) under the British Society of Plant Breeders (BSPB) protocol analyse the performance of sports perennial ryegrasses under intensive wear pressure in line with a winter sports season.  The trial plots are sown in spring, and a “wear simulation machine” is applied from autumn through to the following spring.  Individual cultivars are replicated three times and scored for traits such as Visual Merit; Live Ground Cover; Shoot Density and Recovery; each scored on a scale of 1-9 (9 is highest).

A ryegrass cultivar must be subjected to three successive wear trials (sports seasons) to be listed in Table S1 of the annual publication “Turfgrass Seed” (aka “the STRI/BSPB booklet”).  Table S1 represents a ranking of Mean scores (the combined average of Visual Merit and Live Ground Cover) of approximately 100 perennial ryegrass varieties.

Elite Sport features four of the top-six cultivars in the S1 table and contains 40% by composition of the new #1-ranked Europitch (Mean = 8.1).  Overall, the product blend has an outstanding Mean score of 7.92.  This score translates into Elite Sport being the industry-leading performing product for winter sports use in the UK.

In addition to performance underwear, the blend has other traits of interest to grounds managers of elite winter sports surfaces.  Barcristalla (25% of the mix) is ranked #1 in the top-60 listed varieties for dark green colour and has exceptional Drechslera leaf spot and Fusarium (Microdochium) tolerance (source: turfgrass-list.org).  These two factors are particularly important to stadium environments under intensive disease pressure and the scrutiny of high-definition TV cameras.

Three of the four varieties have also been put their paces at Barenbrug’s dedicated UK research station, Cropvale, in Worcestershire.  Here, wear simulation is monitored using Digital Image Analysis (DIA) to objectively analyse performance.

Elite Sport is being successfully tested in pilot form at Heart of Midlothian FC, following a full pitch reconstruction in the summer of 2018.
