NPLB14016U CANCELLATION: Weed Biology and Management
Bacheloruddannelsen i naturressourcer
The frame of references of the course is identification, biology, ecology, competitive ability,effects and management of weeds. This applies to weeds of agriculture, horticulture and forestry, as well as invasive species and environmental weeds on public land and “natural” plant communities. The emphasis is placed upon the quantification of the harmful effects of weeds in relation to their biology and ecology, and how the weed floras, by ways of mere evolution and adaptation, infest areas and sustain control measures. Tillage, crop rotation and physical, biological and chemical control measures are integral parts of the course, as is the quantification of the efficacy of the control measures and their advantages and disadvantages as well as their impact on weed populations and plant communities inside and outside the arable land. Legislation and impact of various domestic and foreign action plans on pesticides will also be part of the curriculum. There is one excursion in first week of June to Hardi International, a manufacturer of sprayers.
After completing the course the students should be able to:
Knowledge:
- describe origin, biology, ecology and distribution of weeds on
arable and public land.
- show overview of common weed control measures such as cultural,
physical, biological and chemical
- describe the legislation concerning weeds and invasive species
- summarise environmental impacts of weed control methods
Skills
- demonstrate ability to identify weeds at seedling stage
- explain interaction between the crop/natural vegetation and the
weeds
- analyse harmful effects of weed/crop competition in relation to
agronomy and phenological development of plants
- quantify weed-crop competition, thresholds and herbicide
selectivity
- communicate weed management issues as an integral part of crop
production and protection to non-specialists
Competences
- discuss proper decision making in judicious weed management on
the theoretical as well as the practical level
- evaluate novel approaches in the field of weed management and
crop protection at large
- discuss the agricultural and environmental issues of using
various weed management methods be it physical or chemical.
- put into perspective the effect of manipulating agro-ecosystems
in relation to food production and sustainability

theoretical exercises will deal with physical weed management, the distinction between longevity and life-forms of weeds, weed management intensity and the environmental impact of weed management measures.
