“Weed control is becoming more and more complex. With the evolution of the regulatory environment and strong emergence of resistant weeds, farmers are looking for new sustainable IWM strategies to preserve their field production assets.”
On May 31 more than 220 farmers, advisors and distributors, as well as a group of Bayer customers from the Middle East met for the 15th HerbInnov in Marne-la-Vallée. The objectives were to focus on issues related to weed control and the solutions available to sustain the profitability of farms. The morning provided an opportunity for exchanges between experts and farmers, the afternoon for a visit to the multi-year field trials platform.
Each new weed spot in the field has to be controlled with the objective of minimizing the seed bank from the beginning. Resistance can only be seen when it is already too late and interventions, whatever they are, do not allow a return to a satisfactory situation. Farmers should be aware that their agronomic practices influence the evolution of resistance to these weeds.”

Exchanges and experience sharing
To set up these strategies, farmers and specialists were able to interact on various leverages to control weed development during their visit to the platform. On the 4-hectare trial platform where wheat, maize, potatoes and beetroot are sown, farmers assessed in real-life conditions the potential for combining agronomic and chemical techniques to sustainably manage weeds and preserve yields.

“This 15th HerbInnov highlighted the multiple solutions to be combined and the need to exchange and co-build solutions in order to find a suitable strategy for each field,”
Gabriel Carn said in conclusion.
And for 2019…
There will be not one but five trial platforms set up in the main production areas of France. "These regional platforms will allow us to stick as closely as possible to local issues," says Guillaume Chancrin, Bayer Technical Manager. For example in the north where sugar beets will be incorporated into the rotation and in the East where it will be necessary to take into account the difficulty of integrating spring crops.”
