Themes about weed biology and ecology, as well as how different weed management practices reach the weeds in a species specific way will be discussed in lectures, exercises and a self study and seminars.
- Shall understand the biology of the different groups of weeds as well as for the most important weed species
- Shall understand how different direct and preventive methods influence different weeds in a species dependent point of view.
- Knowldge on weed-crop relationships, including both competition and allelopathy, and how different weed managements influence on the relationships.
- Knowledge on innovative and site specific management strategies.
- Shall be able to emply the knowledge for developing new strategies in different weed-crop situations.
- Evaluate and include different weed strategies in a broader point of view, including also other aspects in the agroecology perspective.
The theme will be discussed in lectures, exercises and a self study and seminars.
