PLV340 Weed Biology and Weed-Crop Relationships

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.

In parts of the course, we will facilitate for individual focus within weed control in arable crops (cereals etc.), in fodder production (grassland/pasture) or in green/urban areas. This will ensure relevance for students both within plant science, animal science and green areas/landscape engineering.

Knowledge:

• 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.

Skills:

• Shall be able to emply the knowledge for developing new strategies in different weed-crop situations.

Competence:

• Make suggestions for control strategies also for other weed species (than those that have been reviewed specifically in the course) by using general knowledge and skills for reviewed species. Evaluate and include different weed strategies in a broader point of view, including also other aspects in the agroecology perspective.
