We spoke to <strong>Anne Mette Dahl Jensen, Product Development Manager at DLF<\/strong>, a global turfgrass seed company, after the recent International Turfgrass Research Conference ITRC2025 in Karuizawa, Japan, about current trends in the industry.<\/p>\n<p><strong><em>You just returned from a major turfgrass conference. What would you say was the dominant topic this year?<\/em><\/strong><br \/>\n<strong>Dahl-Jensen<\/strong>: The overarching theme was sustainability and technology \u2013 especially in terms of breeding and maintaining turfgrass.<\/p>\n<p><em><strong>What are the main markets driving the turfgrass industry today?<\/strong><\/em><br \/>\n<strong>Dahl-Jensen<\/strong>: We generally divide the market into two parts: the consumer market, which includes home lawns and private gardens, and the professional market, such as golf courses, football fields, cricket grounds and other sports areas. While the consumer market is large in volume, the professional side is where most of the innovation and research are focused, especially at conferences like this.<\/p>\n<p><em><strong>How has climate change impacted turfgrass development?<\/strong><\/em><br \/>\n<strong>Dahl-Jensen<\/strong>: It has definitely made things more complex. In the past, we had access to herbicides, fungicides, insecticides and unlimited water \u2013 the main focus was on aesthetics: density, color and appearance. Today, especially in Europe, we&#8217;re facing strict regulations on pesticides and water use. That means we need grasses that are drought-tolerant, disease-resistant, and require fewer inputs. All of these traits have to be bred into a single plant \u2013 which makes the breeding process significantly more complicated.<\/p>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-mdj0ma6f-a1f80b746483269d978335dd5df8b92d\">\n.avia-image-container.av-mdj0ma6f-a1f80b746483269d978335dd5df8b92d img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-mdj0ma6f-a1f80b746483269d978335dd5df8b92d .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-mdj0ma6f-a1f80b746483269d978335dd5df8b92d av-styling- avia-align-center  avia-builder-el-4  el_after_av_textblock  el_before_av_textblock  av-has-copyright av-copyright-always'  ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-30800 avia-img-lazy-loading-not-30800 avia_image ' src=\"https:\/\/golfsustainable.com\/wp-content\/uploads\/2025\/07\/20240730_085636-1500x430.jpg\" alt='Dollar spot' title='Dollar spot'  height=\"430\" width=\"1500\"  \/><\/div><small class=\"avia-copyright\">Dollarspot is the most challenging illness at the moment (Foto: Petra Himmel)<\/small><\/div><\/div>\n<section  class='av_textblock_section av-mdhd14m0-4aa1369ce01f078ef1dadbb83047a8f1 '  ><div class='avia_textblock' ><p><em><strong>Are some regions dealing with these challenges more easily than others?<\/strong><\/em><br \/>\n<strong>Dahl Jensen:<\/strong> Not really. Every region has its own difficulties. In Japan and parts of Asia, they use warm-season grasses like Zoysia and Bermuda, which tolerate heat and salinity but still face disease issues. In Northern Europe, we\u2019re restricted in herbicide and fungicide use, so weeds and diseases are a major problem. Southern Europe faces transitional zones with added stress. Even the U.S., with fewer restrictions, faces challenges \u2013 but often from a different perspective.<\/p>\n<p><em><strong>In golf equipment, the U.S. dominates global trends. Is it the same in seed development?<\/strong><\/em><br \/>\n<strong>Dahl Jensen:<\/strong> Not to the same extent. While many U.S.-bred varieties are exported to regions like Southern Europe, the Middle East or Japan, it&#8217;s not a universal standard. U.S. breeders often focus on dark green, visually appealing varieties \u2013 and those are popular in certain regions for aesthetic reasons, even when they\u2019re not ideal agronomically. Tradition and visual preferences play a huge role in variety selection.<\/p>\n<p><em><strong>What was your personal takeaway from the conference?<\/strong><\/em><br \/>\n<strong>Dahl Jensen:<\/strong> For me, it confirmed that the path we&#8217;re taking in Europe \u2013 with more focus on sustainable turf and reduced pesticide use \u2013 is the right one. What surprised me is that many international researchers are still very focused on optimizing pesticide use instead of looking for alternatives. There&#8217;s still too little emphasis on pesticide-free management strategies.<\/p>\n<p><em><strong>Is the health impact of pesticides ever discussed at these conferences?<\/strong><\/em><br \/>\n<strong>Dahl Jensen:<\/strong> Hardly at all.. The health topic simply isn\u2019t part of the mainstream conversation. Maybe one session touched on it, but it&#8217;s not a major focus.<\/p>\n<p><em><strong>Were there any key disease or breeding topics that stood out?<\/strong><\/em><br \/>\n<strong>Dahl Jensen:<\/strong> Yes, definitely. One whole session I attended was focused on turfgrass diseases, and two out of three presentations were about Dollar Spot. It\u2019s now one of the most economically damaging turfgrass diseases globally \u2013 we\u2019re seeing it across the U.S., Europe, and even the Nordic countries. Another major topic was water \u2013 both in terms of increasing drought, restrictions on irrigation water use and declining irrigation water quality. This has become a central issue worldwide and has gained importance even since the last conference four years ago.<\/p>\n<p><em><strong>Do you feel the golf industry is keeping up with these developments?<\/strong><\/em><br \/>\n<strong>Dahl Jensen:<\/strong> Awareness is growing. At the last few conferences, there were seminars specifically for practitioners, and many people from the golf industry attended. But the problem is that we still lack enough region-specific research \u2013 especially in Europe. A lot of U.S. studies don\u2019t translate directly to our conditions, and adapting them can be misleading. Climate change is moving faster than our research can keep up with.<\/p>\n<p><strong>How long does it actually take to develop and launch a new grass variety?<\/strong><br \/>\n<strong>Dahl Jensen:<\/strong> It takes about 10 to 15 years from the start of a breeding project until a new variety is ready for market. That\u2019s why events like this conference are so valuable \u2013 they help identify the most pressing challenges so we can start breeding today for the problems we\u2019ll face in 10 to 15 years.<\/p>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_four_fifth-e8bcfb0dd38e4ffbb23d71c76efe0ae8\">\n@keyframes
