Herbicide tolerant varieties
working group

The newly created EWRS Working Group Herbicide Tolerant (HT) Varieties did gather for the first time formally on 23rd of November, 2012 at the University of Bingen, Germany. Herbicide tolerant varieties is for this WG defined as the umbrella description for varieties that become tolerant through mutagenesis as well as for varieties that are improved via genetic modification. The active participation of the 23 European scientists from 15 organisations (10 countries) reveal that there is a strong interest in the scientific community to increase understanding of Integrated Weed Management in and Sustainable use of these new agronomic systems in Europe.

The commercial introduction of the HT varieties in Europe goes hand in hand with periodically very polarized and emotional discussions. The members of this new WG committed to look for a scientific and balanced evaluation of the agronomic impact that these HT varieties will cause. Impacts to be studied would include weed management in the new varieties as well as in the overall crop rotation, advantages and/or disadvantages for the rotational systems, watch outs and opportunities for HT varieties in specific agricultural systems, economic as well as agronomic sustainability.

As some HT varieties obtained via mutagenesis are finding their commercial way into European agriculture it was agreed to prioritize the evaluation for some of these crops.

Ivo Brants (Monsanto) was elected as coordinator and Prof Jan Petersen (University Bingen, Germany) was nominated vice coordinator.

A visit to the greenhouses with screening for herbicide resistant weeds and a view on an outdoor trial with ClearField® OSR was an appropriate end of the first meeting of the WG Herbicide Tolerant Varieties.

Interested people are invited to attend the next meeting of the WG Herbicide Tolerant varieties which will be held on Sunday 23rd June, 2013 in Samsun, Turkey (preceding the EWRS symposium) and will be jointly organised with the WG Optimization of Herbicide Dose. An invitation for participation has been extended to the WG Herbicide Resistance (weeds).

New Workshop of the EWRS working group herbicide tolerant varieties New
Venue: Novi Sad, Serbia
May 29-31, 2017

The EWRS Working Group "Herbicide Tolerant Varieties" will hold its next workshop at The Institute of Field and Vegetable Crops in Novi Sad, Serbia. The workshop will take place from May 29 – 31st, 2017. Dr. Goran Malidža from The Institute has kindly accepted to act as our local host.

A promotional movie of The Institute of Field and Vegetable Varieties in Novi Sad can be found on
https://www.youtube.com/watch?v=zI1g4SJ5CL4 .

Travel and accommodation are at own expense. Selected exceptions could be made for students after evaluation (official application/justification needed). Hotels are located about 10-12 km from the workshop venue (at The Institute) and the participants will be transported by bus of the Institute.

The timing (end May) and location provide a great opportunity to combine research presentations from participants with a field visit to herbicide tolerant technology trials at the Institute of Field and Vegetable Crops in Novi Sad.

Interested persons that have the intention to attend are kindly asked to notify Ivo Brants by a simple e- mail (ivo.o.brants@monsanto.com) as to be included in future communications related to this workshop.

We ask participants to indicate the intention to present some related research work and to provide the topic (technology, crop, draft title) which will allow to generate appropriate presentation sessions. More information on the EWRS Working Group "Herbicide Tolerant Varieties" can be found on http://www.ewrs.org/Herbicide_tolerant_varieties.asp


We hope to see many of you in Novi Sad next Spring. Goran Malidza, Jan Petersen & Ivo Brants.
