Level: 7
Credits: 15
School: Engineering and Science
Department: Natural Resources Institute
Course Coordinator(s): Maruthi Gowda / Sophie Bouvaine

Specification

Aims

This course enables students to:

Develop an understanding of the 'pathosystem' and how it is affected by environment and in turn how this affectsdisease incidence and severity;
Evaluate different methods of disease control and the decision-making process for selection of appropriate methods in order to select disease management options appropriate to the pathogen and agroecosystem;
Apply the principles of Integrated Pest Management to plant disease control;
Gain the technical know-how to design sustainable disease control strategies.

Learning outcomes

On completion of this course, students will be able to:

1. reflect on the biology and aetiology of different plant pathogens and how this relates to control measures;
2. apply knowledge of the host-pathogen-environment triangle and critically evaluate its effect on disease incidence and severity;
3. quantify crop disease, estimate crop loss and assess when a disease control intervention is needed;
4. select a disease control measure suitable for the pathosystem and appropriate to the production system concerned;
5. combine appropriate control technologies into the design of an integrated control strategy.

Indicative content

Introduction to the terminology of plant disease and principles of disease control.
Life cycles of different plant pathogens and aetiology of the diseases they cause.
Plant disease epidemiology in relation to disease management.
Crop loss assessment methods.
Control methods for plant diseases.
Decision-making in the design of control strategies,
Integrated disease management and integrated crop protection.

Teaching and learning activity

The course will be taught through a series of lectures on the aetiology of plant diseases and the control methods available and these will be linked to written assignments to develop the ability to design control measures appropriate to a particular disease and the farming system concerned. Lectures will account for 60% of the time with the rest of the time allocated to seminars and written assignments.
