War of the Roses
A Case Study in Plant Pathology
In this case, students use lab techniques to determine how the protagonist of the story, a student in a plant pathology class, can find out what is wrong with his mother’s roses. The case introduces students to sources of information for the proper diagnosis of plant diseases as well as methods of controlling plant diseases. Developed for the introductory laboratory in a basic upper-level undergraduate plant pathology course, the case could also be used in other courses such as introductory agriculture, horticulture, botany, and biology, where there is an interest in the diagnosis of plant diseases.
- Investigate the processes involved in diagnosing a plant disease.
- Illustrate how symptoms are used to describe a plant disease and how these descriptions are then used for comparison to previously described plant diseases.
- Learn how to make and use slides and microscopy for the identification of a plant disease.
- Examine information requested by clinics diagnosing diseases and determine why this information is needed.
- Investigate where information (books and Internet) concerning plant diseases can be obtained.
- Consider factors such as environment, soils, and specific cultivars of plants and how they can have an effect on a plant disease.
- Examine the control measures used in different situations for controlling a plant disease.
- Examine plant resistance and its effect on the development of a plant disease and how it is used in disease control and determine its limitations.
