Lolium spp. populations resistant to ACCase and/or ALS inhibitors have been reported in the three countries involved in the project: L.
multiflorum and L. perenne are present in Denmark and Italy, while L. rigidum is found in perennial cropping systems in Italy and Greece.
Lolium spp. is a serious weed problem all over Europe and therefore represents a unique opportunity for gaining a better understanding of
the evolutionary process leading to herbicide resistance and develop transnational management strategies that can be adapted to national
conditions.
The project aims at monitoring, mapping, developing innovative detection tools and characterizing (patterns, levels and resistance
mechanisms) selected resistant populations as well as devising resistance management strategies for Lolium in various agronomic
situations. This is a truly European project where each participating country will focus on specific tasks and complement each other to
devise novel weed management strategies. Partners will continuously exchange information and plant material.
Monitoring, collection of information on fields in which resistance evolved and mapping the diffusion of resistant biotypes will be done in all
countries. Target site resistance mechanism will be studied in Italy where they will also devise a robust tool for quick diagnosis of this type
of resistance as well as to characterise the first glyphosate resistant Lolium population in Europe collected in fields managed through
conservation agriculture. The Danish partner will focus on metabolic herbicide resistance and develop a reliable method based on next
generation sequencing to diagnose this type of resistance. They will compare biotypes of Lolium spp. sampled from diverse cropping
systems in the three countries. The partners in Greece will focus on the biochemical and molecular diagnostic tools for glyphosate resistant
Lolium spp. Maps of diffusion of all resistant biotypes as well as resistance management guidelines will be made all available online.
Relevant stakeholders, farmers? organisations, farmers? advisors, and national herbicide resistance action groups will be involved
throughout the project in devising resistance management strategies, discussing and disseminating the outcomes of the project.
Dissemination will mainly be done through the web. An open-day meeting will be organised in each country at the end of the project to
present the results.
