Purity you can rely on. DLF is aPuwritoyryldoulecaandererlyinonthe supply of seed to professionals, where quality and purity are essential. Our seed has been chosen for three world-class football tournaments (South Africa 2010, Brazil 2014 and Russia 2018), for international golf championships such as the Phoenix Open and by many leading turf producers. In a world where environmental factors and changes in pesticide legislation mean it is becoming increasingly difficult to achieve high purity standards, DLF have developed a new programme within their production chain to safeguard quality and ensure they remain the preferred, reliable, supplier to the top turf managers worldwide. While EU minimum standard seed can contain up to 2% weed, DLF field consultants, working closely together with specially selected growers, have identified the cleanest fields to grow and harvest only the purest crops to produce ‘00’ and ‘S’ purity rated seed mixtures.

Selected growers We choose our most experienced growers who devote their cleanest, weed- free fields to grow the purest crops. Field management Constant, careful monitoring and flawless weed control takes time and naturally, we compensate our growers for the extra time and effort they put in. DLF inspection Our DLF field consultants join the growers for regular inspection and advice. Separate storage DLF Select Seed is stored separately from other seed at the farm and is clearly marked to make it easily identifiable. 3 Specialised cleaning lines Specialised cleaning lines ensure optimal cleaning and removal of any weed seeds or other grasses, monitored by trained cleaning operators. Cameras Cameras by the cleaning lines analyse seed samples. If contaminants are found, machines are adjusted to keep only the clean seed in the box. Analysis The cleaned seed lot is analysed and labelled with the correct quality grade.

Harvest Inspections will identify r any weeds or unwanted grasses which will be isolated, ensuring the harvest collects only the cleanest seed. Packaging Batches of super-clean h DLF Select seeds are bagged, labelled and stored at our warehouse, ready for shipment to our customers. by DLF The Environmental Solution Stronger Establishment The larger 4turf® seeds contain more energy reserves for stronger, faster establishment and healthy plant development. 4turf® tetraploid ryegrass demonstrates better germination at temperatures as low as 4ºC when compared to diploid, giving advantage for cool weather overseeding. Drought Tolerance The larger root system and natural water reserves makes 4turf® more drought tolerant and quicker to recover when rain returns. Trials conducted in the Loire Valley in France confirmed that 4turf® cultivars are significantly more drought-tolerant than diploids. Disease Resistance and Winter Performance In European trials, 4turf® shows the highest disease resistance during the autumn and winter months and increased resistance to weed invasion, thanks to the improved energy reserves and stronger rooting system. Excellent Colour 4turf® delivers a deeper, glossier dark green colour, even through the difficult winter period, that develops quicker and lasts for longer than traditional varieties of perennial ryegrass. salt by DLF Salt-tolerance backed by science Whether salinity is due to salt in the soil, the nearby sea or the irrigation water, the 4salt® solution offers better plant growth than standard grass seed mixtures. The 4salt® concept is a result of continuous testing and selection in our R&D facilities, to identify the most salt-tolerant varieties of slender creeping red fescue which are then incorporated into mixtures optimised for saline conditions. 4salt® can be found in Johnsons J Links mixture, the obvious choice for coastal golf courses, roadsides and areas using recycled water with varying or 4 unknown quality.
