Areas of Competence the Course Will Address
Basic Sciences: Knowledge of chemical and physical properties of pesticides to understand their use in crops and effects on target and non-target organisms.
Applied Sciences: Understand rationale behind pesticide development, mode and site of action and classification in relation to use, load and ecotoxicology. Comprehend assessment of efficacy/toxicity, and apply models to assess joint action of mixtures Transfer knowledge of application and in crop efficacy to non-target organisms in the terrestrial and aquatic environments. Evaluate various theories and principles of pesticide action and make sound judgment of impact of pesticides on environments.
Ethics and Values: Pesticides has generated controversial issues in the public and in some scientific quarters. Students will be aware of various attitudes which will make them reflect over current use and make them able to discuss pesticide use in agriculture and society at large in relation to both benefits and side effects.
 
Course Objectives
To expose students to scientific principles of chemical, physical and biological properties of pesticides in relation to their use in agriculture, horticulture, forestry and public land and their ecotoxicological side effects. The curriculum encompasses the advantages and disadvantages of pesticide, the knowledge of which is pivotal for those who wish to work with pesticide development and managing their use within the industry, agriculture and public domains.
 
Course Contents
The rationale behind the development of pesticides, their use and physical and chemical properties is the frame of references of the course. The importance of mode of action and site(s) of action of pesticides will be stressed and the linked to chemical properties, uptake translocation and metabolism in plants and target and non-target organisms. The principles of assessing pesticide selectivity and, be it in the research and development processes or in ecotoxicological contexts, will be an integral part of the course. The formulation of pesticides and use of adjuvants to enhance efficacy, either by the manufacture or by the end user. Various reference models to assess joint action of pesticide mixtures and the implication to their use and side effects. Aquatic and terrestrial ecotoxicology in relation to pesticide loads, intentional and not intentional discharge in the environment and also the ecotoxicological effects of pesticides on population and communities. Risk assessment of the pesticide use in relation to ecotoxicology and the national and international registration systems. The course also consistsof an excursion to Cheminova A/S, The National Environmental Research Institute (DMU) Silkeborg and Agrolab A/S
 
Teaching And Learning Methods
Lectures will outline the theoretical background for the course and support the practical and theoretical exercises. The excursion will take place in the first part of the course, giving an introduction to a pesticide producing chemical company, a company involved in field tests and registration and an environmental research institution. The practical exercises will assess the topics: application, assessment of efficacy, pesticide uptake, mode of action, recovery and mixture toxicity. The test organisms are plants, algae, daphnia, earthworms and fungi. The use of standard OECD and ISO guidelines will be preferred. The theoretical exercises will deal with proper statistical analysis of the practical exercises by statistical software, calculations of spray applications and pesticide load, simple models to assess fate of pesticides in the environment (short, as it is done in more detail in other courses), calculations of uptake and translocation of pesticides in plants, the use of Quantitative Structure Activity Relationships (QSAR's), calculations and discussions of environmental impact of pesticides, risk assessment and legislation needs.
