Excursion of the DPG working group Herbology 2025
The 2025 meeting of the Herbology Working Group was again held as an excursion under the motto “Integrated control of difficult-to-control weeds in cereals without Flufenacet”. This year we went to the Jens Heisrath Experimental Station (Rottweil, Baden-Württemberg) on June 2 and 3, 2025.
Since 2012, the working group has been organizing the German Working Meeting on Weed Biology and Control together with the Julius Kühn Institute Braunschweig and the Technical University of Braunschweig.
The next conference will take place from 24-26.02.2026 in Braunschweig.

- Biology and ecology of weeds, integrated weed control, and related topics
- Scientific information exchange about all topics related to herbology
- Building networks not only with herbologists, but with colleagues of adjacent disciplines as well (like ecologists, geobotanists, vegetation specialist, conservationists, etc.)
- Hosting conferences beyond working group meetings (like the German Conference on Weed Biology and Weed Control, www.unkrauttagung.de)
- Excursions and fieldtrips to deepen special knowledge
- Herbicide resistance
- “New” weed species (neophyte invasive weeds, poisonous weeds, perennial weeds, previous known weeds with re-growing relevance)
- Weed mapping (occurrence and growing of weeds)
- Cultivation systems and weed infestation / integrated weed control
- Population and dispersions-dynamics / weed-ecology
- Biodiversity
- Weed control and environment
