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.

Dear members and colleagues,

In this month's newsletter, I have a series of slides titled: Building our house EWRS! I had the opportunity to present this at the International Weed Science Congress in Prague in 2016. I invite you to have a look at my self-explanatory view on the structures of our society. You can see it at:
