208-307 Plant Pathology and Pest Management

Topics covered include:

• taxonomy, identification and biology of the main groups of plant pathogens and abiotic causes of plant diseases;

• host-pathogen relationships, and the nature of resistance and pathogenesis;

• the processes leading to plant disease epidemics and their evaluation;

• the types and uses of chemical fungicides, the bases of biological control of plant diseases, insects and weeds; and

• the management and integrated control of plant diseases in general.

Practical work includes the identification and diagnosis of common diseases; and the development of skills in research techniques and methodology in plant pathology.

On completion of this subject, students should:

• be familiar with the biology and taxonomy of the major biotic causes of disease;

• be aware of the factors leading to disease epidemics;

• be capable of diagnosing common diseases of agricultural and horticultural crops;

• have a basic understanding of the use of molecular biology techniques in plant pathology;

• be able to formulate a practiable approach to integrated control in commercial species.
