Free EWRS training online Course on updated HRAC classification


In March 2020, the Global Herbicide Resistance Action Committee (HRAC) completed its updates on the herbicide mode of action (MOA) classification system. Changes since the last update in 2010 include the addition of 14 new active ingredients, rationalization of chemical family names, and four new or updated modes of action. With this update, Global HRAC will transition from letter to number mode of action codes. This was done in coordination with the Weed Science Society of America (WSSA) and the Australian organizations in order to agree on one worldwide global herbicide classification instead of the three previous ones.

As the HRAC herbicide mode of action classification is used by researchers, extension specialist and farmers around the globe, the revision of the classification has substantial impact on the daily work of many of us.

With the training course, we would like to explain the rationale behind the update of the HRAC classification and provide an overview of the most important updates. In addition, we will discuss the most important impacts of the updated classification on herbicide resistance management in Europe.  

The training course will be organised in a webinar format. After the presentation of the updated HRAC classification, there will a discussion session for all questions related to the updates.

Date: 06.05.2022, 09:00-11:00 CET
