PPATH 300 Horticultural Crop Diseases (2)
(GN)
Diseases of horticultural crops are examined stressing their cause, diagnosis, control and understanding the roles they play in national and international trade and bio-security concerns. The biology of plant diseases involving a broad range of biotic and abiotic plant pathogens will be discussed. The objectives are that the student completing the course will 1) be able to describe the causes of plant diseases in general and horticultural crop diseases in particular; 2) be able to explain the interactions that occur among the plant, the environment, and biotic and abiotic agents during disease development; 3) have the ability to diagnose and explain the management of key diseases of horticultural crops; and 4) be able to describe the economic and social impact that plant diseases have on horticultural crops, including how the world trade of these crops can result in the global spread of pathogens important to other agricultural crops and native plants in the environment. A once-a-week, 2 hour laboratory will stress practical aspects of identifying diseases and plant pathogens and gaining experience in selecting appropriate disease control practices. The course is recommended for majors in horticulture and urban forestry but is appropriate for everyone interested in growing plants for enjoyment or profit or in maintaining the health of horticultural crops. This course provides an introduction to plant pathology in general and can be followed by more in-depth courses in plant-microbe interactions, mycology, nematology, phytobacteriology, air pollution impacts on terrestrial ecology, or forest pathology. Enrollment is expected to be between 25 and 50 students. It will be offered every Fall semester. Students will be evaluated based on a term paper with a topic of the student’s choosing as well as short essays and objective answer questions on quizzes, exams, and a final exam.
Note : Class size, frequency of offering, and evaluation methods will vary by location and instructor. For these details check the specific course syllabus.
