4TURF® IS BRED FOR BETTER TURF PRODUCTION As a turf producer you have high standards. You want to grow perfect, yet easily maintained turf because that’s what your customers expect. And you want to run an efficient business providing the maximum output of top-quality turf for the least cost. Our innovative 4turf® makes this happen. We bred it for the business-building characteristics you need for your turf production. 4turf® is a unique turf-type tetraploid perennial ryegrass with rapid establishment, good growth in cool temperatures, and 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® out-perform diploid perennial ryegrasses in numerous ways. They have larger, high-energy seeds for rapid establishment, even when soil tempera- tures are as low as 4°C. Rapid establish- ment 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-tolerance and increases the efficiency with which the plant uses nitrogen.

FASTER ESTABLISHMENT CUTS PRODUCTION TIME AND CROWDS OUT WEEDS The greater energy reserves within 4turf®’s larger seeds support stronger, faster turf establishment and healthy plant development. This cuts your production time and extends your turf-growing season. 4turf® varieties will even germinate at temperatures as low as 4°C. Faster plant growth helps fight weed invasion at the critical establishment phase, and provides you with a more cost-effective and healthy turf.

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 production. 4turf® varieties are not just drought-tolerant, they also recover faster 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. EXCEPTIONAL DISEASE-RESISTANCE FOR REDUCED MAINTENANCE AND PESTICIDE APPLICATIONS 4turf®’s larger energy reserves significantly increase the plant’s natural disease- resistance. This valuable characteristic helps you maintain a healthy looking turf with less use of pesticides, which makes your turf production cheaper and easier to maintain. Independent researchers (for GEVES in France and SCANTURF in Scandinavia) recorded excellent resistance to Microdochium patch, red thread and rust diseases. Independent researchers from other national lists (STRI in the United Kingdom and Grasgidsin the Netherlands) repeated these trials, and also measured exceptional resistance to red thread.
