| Course description |
This course introduces the student to the causal agents, nature and dynamics of plant disease. Topics to be covered include major diseases of economically important plants, the biology of pathogens, factors influencing disease development, diagnosis of disease, and principles of plant disease control. |
|||
| Objectives |
1. Awaken you to the microbial world and the nature of diseases of plants 2. Develop an appreciation for the importance of plant disease to humans. 3. Learn the basic biology of major groups of plant pathogens. 4. Become familiar with terms and references used to diagnose plant disease. 5. Understand principles for plant disease control. |

Text: |
Essential Plant Pathology , Schumann & D'Arcy, 1 st edition. This very recent book is excellent for this class. It comes with a CD of disease lessons and illustrated glossary (these materials are also available online at the APSnet Education Center (see below)). The book is in stock at the OSU bookstore (~ $78). |

Plant Pathology Laboratory Manual; Heffer, Powelson and Johnson, revised 2007 $15 - Please read the pertinent sections of this manual before every lab meeting, and have it with you during the lab session.

| Lectures |
Initially, the lecture period will focus on concepts and principles of plant pathology. Monday lectures will emphasis the biology of pathogen groups to be covered in the lab section that week. Toward the end of the term, the lecture content will shift to suppression and management of plant diseases. |
|||
| Labs |
This is your opportunity for hands-on experience with diseases of plants. The climate and botanical diversity of western Oregon typically provide us with an excellent assortment of unhealthy plants to examine in class. |
|||
| Field trip |
There will be a ~2 hr field trip on Tuesday, September 25 to visit disease situations in the local area (this is in lieu of lab). We will leave from the back lot of Cordley Hall at 9:00 (return around 10:50 ) and again at 10:00 (return around 12:50 ), and again at 2:00 (return around 3:50 ). |

| Exams |
A midterm exam will be held on Friday, October 19, and will cover lecture and lab material over the first four weeks. A second midterm exam will be held Wednesday, November 14 and will cover through viruses (Nov 13). The final exam is scheduled for Tuesday, December 4 at noon; this exam will be comprehensive covering the concepts presented throughout the course. No make-up exams will be given. If one midterm is missed, a score of 50 will be received for that exam. Missing a second midterm, either of the finals, the quizzes or assignments will result in a score of zero. Copies of previous examinations are available on the course website. |
|||
| Lab assignments, quizzes and lab final |
A disease-of-the-week will be assigned in two of the lab meetings. Your task will be to examine a plant with an unknown disease, diagnose the disease and complete a worksheet that requests information about the disease biology, the pathogen causing the disease, and its control. Short quizzes (6 points each)will be given at the beginning of every lab meeting (except the field trip) . On Thursday , November 29, there will give a comprehensive lab final – this is where you will prove to yourself that you are ready for the real world! |
