Plant Pathology

There are 8 lessons in this course:

1. Introduction
2. Types of Diseases
3. The Lifecycle of a Disease
4. Control Techniques
5. Selected Pathogen Diseases ? Ornamentals
6. Selected Pathogen Diseases ? Crops
7. Non-Infectious Diseases
8. Special Project

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

• Describe a range of pathological problems that affect plants.
• Describe symptoms of a range of diseases that affect plants.
• Describe disease life cycles and explain how this knowledge can be applied in disease control
• Explain the methods used to control diseases
• Demonstrate a comprehensive knowledge of a particular plant pathogen.
• Identify and describe a range of non-infectious diseases and problems that affect plants
• Identify and describe a range of common pathogens that affect ornamental plants.
• Identify and describe a range of common pathogens that affect crop plants

• The first part of the course develops an understanding of the different types of problems which can occur and how to identify them.
• Terminology is covered in some depth, so as to enable the student to be able to read & understand books & articles written about plant diseases. Other major topics of study include "symptoms" (ie: Necroses, Hypoplases, Hyperplases, etc), "types of pathogens" (ie: Viruses, bacteria, fungi, Nematodes, etc), and the lifecycle of a disease.
• The second part of the course looks at how to control pathologyproblems. The major methods of controlling pathogens (ie: Sanitation, resistant varieties, biological controls, soil drenches & chemical sprays, etc) are all studied, along with types of equipment & safety.
• The third part of the course looks at some of the most common plant pathology problems in commercial horticulture, how to identify them and how they are controlled.
• Some of the problems studied include cinnamon fungus, tree decay, powdery mildew, nematodes, brown rot, blights, turf fungi, damping off and non infectious problems such as temperature burns, air pollution, wind burn and excessive light.
• The course is a highly practical one involving as much time in practical/field work as it does theory.
• No prior formal training is required, though anyone undertaking this course is expected to have some experience in horticulture (either having worked in the industry or having studied in some related discipline.
