Course abstract

Students acquire comprehensive knowledge about the main principles and practical application possibilities of the integrated pest management (IPM), understand the conception of thresholds, and acquire the basic knowledge of the monitoring of harmful organisms.
Understand the biology and ecology of harmful organisms in the context of the postulates and practical application of integrated pest management.
Gain knowledge about sustainable use of plant protection products.

Learning outcomes and their assessment

Knowledge about the conception of integrated pest management (IPM). Understand the importance of the knowledge about harmful organism biology and ecology regarding successful application of IPM, and learn the main principles and importance of the monitoring of harmful organisms in IPM. The first part of independent work – composed description about harmful organisms and their life cycles.
Are able to analyse the importance of different factors (agrotechnology, harmful organism life cycle peculiarities, pesticide modes of action, their impact on the environment, economic aspects, etc.) in decision making. The second part of independent work – create plans of pest management with emphasis on economic thresholds, and on the warning and forecast systems.
Are competent to practically apply IPM, to represent and discuss the practical and theoretical aspects of IPM. The third part and conclusions of independent work – compare various plant protection systems and give critical evaluation of their advantages, disadvantages and introduction possibilities.

Course Content(Calendar)

Kursa plāns/saturs / Course plan
1. Introduction. Origins of modern plant protection. Way until integrated pest management (IPM).
2. Relation between harmful organisms’ biology and ecology and IPM.
3. Groups of causal agents of plant diseases.
4. Principles of IPM. Preventive and corrective measures of plant protection, their effect on populations of harmful and beneficial organisms.
5. Concepts on losses of yield and thresholds.
6. Monitoring of harmful organisms. Registration of diseases, possibilities of diagnostics, characterizing of epiphytotic. Qualitative, quantitative and semi-quantitative methods of invertebrates’ monitoring.
7. Possibilities of diseases' outbreaks dependably from biological properties of pathogens, development features of plant, meteorological conditions and agrotechnological measures.
8. Forecasting of diseases’ outbreaks, used thresholds.
9. Possibilities and problems of implementation of IPM.

Requirements for awarding credit points

Evaluation of the course – a test with a grade.
Students prepare a report and a presentation about the intensive, integrated and biological plant protection systems for one economically important crop in Latvia. These plans are based on harmful organism biology, their possible harmfulness, explanation of pesticide choice, and economical aspects. Critically analyse the biological, economical and social efficiency of all observed systems.

Description of the organization and tasks of students’ independent work

While working on independent work, students study relevant literature about the themes they have heard in lectures and prepare homework for successful discussions at the seminars.

Criteria for Evaluating Learning Outcomes

Knowledge about relevant pests and diseases, their biology in context with crop growing technologies, other agroecological aspects and their management options.
Factors that affect the mark: quality of information source, insight about harmful organism biology in relevance to their management possibilities, quality of the report and presentations’ defence, and students’ ability to defend and explain their opinion and discuss relevant plant protection topics.
