Where do you work?

Aarhus University, Institute for Agroecology

What is your main interest in weed research?

My research area covers herbicide activity under controlled conditions. I am interested in the following areas concerning weeds and herbicides:

  • Influence of climatic factors on herbicide activity
  • Joint-action of pesticides
  • Adjuvants
  • Herbicide resistance
  • Allelopathy
  • Innovative weed control methods (laser, micro spraying, precision spraying)
  • Invasive species
  • Herbicide efficacy on non-target plants
  • Herbicide efficacy and selectivity in seed crops.

Which activities do you plan to promote to reach the objectives of the Working Group?

I will support activities bringing industry, research and practice together to discuss weed resistance management and strategies. Hopefully, this will provide in a better understanding of the causes and results of herbicide resistance and promote interactions between the different groups of people. I will promote activities on communication on IWM and support their implementation through practical guidelines.
