4TURF® IS BRED FOR BETTER LANDSCAPE AND PARK MANAGEMENT As a park manager, landscaper or landscape architect, you work to high standards. You want to establish and grow perfect, yet easily maintainable turf because that’s what your customers and the public expect. You also want to run an efficient business based on the maximum output of top-quality turf for the least cost. Our innovative 4turf® makes this happen. We bred it for the characteristics you need and for the types of landscape that you manage. 4turf® is a unique turf-type tetraploid perennial ryegrass with rapid establishment, good growth in cool temperatures, and a better environmental stress-tolerance against drought and diseases. 4turf® – resilience and stress-tolerance as standard Diploid and tetraploid plants have ryegrasses are a technological step DLF has been breeding resilient tetraploid differing numbers of chromosomes in forward. They perform better because varieties for many years. They show better their cell nuclei. Diploid plants have two they have twice as many chromosome stress-tolerance and an improved ability sets of chromosomes in each cell; sets and therefore twice as much to recover, even in cooler temperatures. tetraploid plants have four. Historically, chloroplast in each cell. The extra perennial ryegrasses bred for amenity use chloroplast boosts chlorophyll production, have been diploid. Tetraploid perennial creating a healthier, high-energy plant. Proven performance you can trust 4turf® varieties out-perform diploid perennial ryegrasses in numerous ways. They have larger, high-energy seeds for rapid establishment, even when soil temperatures are as low as 4°C. Rapid establishment reduces weed invasion, while low-temperature winter growth gives you a healthier, more resilient year-round turf. Beneath the surface, the increased root mass improves drought-tol- erance and increases the efficiency with which the plant uses nitrogen.
FASTER ESTABLISHMENT PROVIDES BETTER TURF QUALITY The greater energy reserves within 4turf®’s larger seeds support stronger, faster establishment and healthy plant development. Faster plant growth helps fight weed invasion at the critical establishment phase, which makes your maintenance operations more sustainable. 4turf® varieties will even germinate at temperatures as low as 4°C.

Its larger root system and natural water reserves help it stay greener for longer. This cuts your maintenance costs and makes for more sustainable turf management. 4turf® varieties are not just drought-tolerant, they also recover quicker when the rain returns. Drought trials conducted in the Loire Valley in France confirmed that 4turf® varieties were significantly more drought- tolerant than diploid perennial ryegrasses. Perennial ryegrass 2n IMPROVED WINTER HARDINESS As temperatures drop, a plant’s metabolism slows down. But to a lesser extent in 4turf®. 4turf®‘s larger energy reserves give it the ability to grow at low temperatures, which makes the turf better able to withstand winter wear. In trials undertaken in Finland, 4turf® showed superior winter hardiness. In Scandinavian SCANTURF trials, it ranked number 1 for general turf quality.
