Purity you can rely on. DLF is a world leader in the 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. SCAN FOR FURTHER INFO DLF PRODUCTION CHAIN PLANNING Sowing the field to harvesting takes two years, so we start planning varieties and quantities two years in advance to ensure availability of the pure seed. SELECTED GROWERS We choose our most experienced growers who devote their cleanest, weed-free fields to grow the purest crops. 4 PREMIUM GRASS SEED MIXTURES 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 Select DLF INSPECTION Our DLF field consultants join the growers for regular inspection and advice. HARVEST Inspections will identify any weeds or unwanted grasses which will be isolated, ensuring the harvest collects only the cleanest seed. BACK TO CONTENTS
