The product is a blend of three perennial ryegrasses: 35 per cent Barorlando, 35 per cent Barcristalla and 30 per cent Barlibro RPR (Regenerating Perennial Ryegrass).
The perennial ryegrass blend has been through scientific and customer testing. The company says it is proven to be wear- and disease-tolerant, provides "camera-ready" colour, and fast recovery.
The mixture and its component parts have been extensively trialled under intense wear pressure at Barenbrug's Cropvale research station in the UK. Objective data recording over two years "conclusively proves" the blend's performance with regard to wear tolerance, the company says.
The mix also delivers dark green, camera-friendly colour which the company says is "far superior to any other premium mixture on the market", with excellent colour in autumn and winter.
Disease tolerance is also highlighted, particularly with regard to Drechslera leaf spot, currently UK stadiums' biggest disease issue. The company claims independent data from the French Turfgrass List shows RPR Stadium offers superior tolerance compared to competitors' mixtures.
RPR breeding is focussed predominantly on recovery or "regeneration" during wear pressure. RPRs possess an unparalleled capacity to recover in that they can produce determinate stolons and entirely new plants to counteract the effect of intense wear or other turf damage.
The new variety Barlibro in RPR Stadium is the next generation of these distinct cultivars, offering superior performance, with respect to the speed and aggression of its stoloniferous growth, Barenbrug says.
Ian Forshaw, head groundsman at the £30m Wigan DW Stadium, said: "Incredibly, we've had five games on the pitch and the grass is only 13 weeks old. It's practically undamaged and in pristine condition. RPR Stadium has drastically reduced the amount of time we have to spend repairing the grass."
Dr David Greenshields, research and development manager at Barenbrug, said: "Our latest R&D programme using digital image analysis allows us to analyse European winter sports ryegrass performance under wear in the UK. The research objectively confirms that Barorlando and Barcristalla offer an unparalleled combination of wear tolerance and dark genetic colour—at levels previously unseen. RPR Stadium offers unrivalled benefits for groundsmen and winter sports pitches across the UK."
