Description
of course
This course introduces you to the basic concepts of the description, cause, and control of plant disease. Representative plant diseases will be selected for the illustration of symptom development, epidemiology, physiological responses, prevention and control practices, and types of pathogenic agents. Emphasis will be placed on the influence of the environment, host genetics and physiology, cell-cell interactions, cellular responses and pathogen biology on disease occurrence, development, and epidemiology.

Course
objectives
By the end of the course you should be able to do the following:
1. Identify the causes of plant diseases and explain the altered physiology associated with diseased plants.
2. Classify pathogens into orders and describe the biology of the pathogens.
3. Describe pathogen life cycles as they related to disease cycles.
4. Determine optimal disease management strategies based on pathogen and host biology
5. Predict the effect of environmental parameters and time on disease epidemiology.
6. Isolate and identify some plant pathogens and demonstrate that they cause disease.
7. Find accurate plant pathology related information and literature.
8. Critically analyze a plant pathology related problem.
9. Integrate information and knowledge from different sources.
10. Effectively communicate interpretations and findings.
Evaluation is based on the components listed below.
3 Lecture Exams 300 pts
Comprehensive Final Exam 100 pts
Quizzes 40 pts
Plant disease topics 20 pts
Disease case studies 20 pts

TOTAL 720
pts Be present at all exams!!!!!!!
Late
assignments
Lab reports, plant disease topics, or collections that are turned in after
the specified date will result in a reduction of 10% of the total point value
for each day it is late.
Missed
Quizzes and Exams
Quizzes that are missed for any reason can not be
re-taken or made up. The lowest
quiz grade will be dropped at the end of the semester. Tests missed with certified medical
excuses or prior instructor approval will be dealt with individually.
Academic
Conduct
Please note that the following are considered academic misconduct by NMSU:
1. Cheating or knowingly assisting another student in committing an act of cheating or other forms of academic dishonesty. [This includes giving other students your collection organisms.]
2. Plagiarism, including submitting examinations, themes, reports [including lab reports], drawings, laboratory notes, undocumented quotations, computer-processed materials [internet documents], or other material as one’s own work when such work has been prepared by another person or copied from another person.
Students may receive a zero grade (F) for plagiarized work, or for the entire course.

Please note that if you have a disability that interferes with your academic progress, you may contact Services for Students with Disabilities at 646-6840 (voice) or 646-1918 (TTY) for an appointment. Services for Students with Disabilities is located in Garcia Annex, Room 102. Current appropriate documentation will be required to receive services.
Attendance at all laboratory sessions is REQUIRED. Evaluation of the laboratory portion of the class will be based on a final laboratory exam, three 2-4 page laboratory reports and a collection of 5 plant pathogens.
Laboratory Exam = 100 pts
Collection = 100 pts
Laboratory Reports = 31 pts
Laboratory Journal = 9 pts
One obligate plant pathogen specimen and four specimens of fungi or bacteria (isolated from diseased plants) in pure culture, that are probable plant pathogens, identified to genus, will be required for the collection.
Three lab reports will be handed in during the semester. The lab experiments that the student can report on are indicated with a * in the following syllabus. Lab reports are due ONE WEEK after the results are collected. You will receive a model report to guide you. Reports should be typed (spell check- required). You will be given plenty of notice.
