Welcome to the
European Weed Research Society
(EWRS) web site

The EWRS is an international organization which promotes and co-ordinates scientific research into all aspects of weed science.

Using this site, the EWRS aims to provide support for international collaboration in weed science, partly by assisting the work of the EWRS Working Groups, and partly by providing general information and resources.

New announcement

Joint workshop of the EWRS "Physical and cultural weed control" working group and the "Weed Resistance" working group titled:
"Physical and cultural weed control tools and their influence on herbicide resistance evolution"

During this workshop we will have an excursion day with visit of field trials on physical and cultural weed control tools, and a visit to companies working in the field.
The second day will be dedicated to the discussion on the efficacy of physical and cultural weed control tools (crop rotation, cover crops, mechanical weeding, physical weeding), and their possible use in the context of herbicide resistance evolution and management will be discussed.

Date: 6-7 April 2020 - Welcome and arrival on April 5th
Venue: Lelystad, the Netherlands

Proposals for contributions are welcome and can be send to both Roland Beffa and Marleen Riemens, but we will send a call in due time.

New announcement

Meeting of the EWRS Working Group "Site Specific Weed Management"

Date: October 30th - November 1st 2019
Venue: University of Southern Denmark, Odense, Denmark

Recent progress in research and engineering of weed sensing, data science, precision sprayers and robotics have made it possible to automate weed identification, weed mapping and site specific control of weeds with advanced sprayers and robots. At this workshop in Odense, we will share these latest progresses and discuss how they enables answering scientific questions and practical applications.
