Course Objectives
1. To provide students with a systematic approach to the diagnosis of a wide variety of infectious diseases and non-infectious disorders of field crops, vegetable crops, fruits and nuts, ornamentals, turf, and shade and forest trees. 2. To introduce students to modern laboratory methods and techniques used for the detection and identification of a wide variety of biotic pathogens, and non- infectious agents associated with nutritional disorders, air pollution injury, and herbicide damage. 3. To instruct students in the basic principles of disease management and provide an opportunity for students to apply learned principles and formulate specific control measures for a diverse group of diseases and disease situations. Note: The course syllabus is a general plan for the course; deviations announced to the class by the instructor may be necessary.
