HOR 237 Integrated Pest Management: Insects and Diseases
Lecture Hours: 3
Lab Hours: 2
Credits: 4
Presents an integrated approach to disease and insect and mite management in the nursery and greenhouse. Covers identification of common insect and mite pests and their natural enemies, insect monitoring, and assessment. Focuses on cultural practices and biological control techniques to manage insect and mite problems. Includes use of insecticides and miticides to manage pest populations. Covers identification of common fungal, bacterial, and viral diseases in the nursery and greenhouse. Discusses monitoring and diagnosing diseases of greenhouse and nursery plants. Focuses on cultural, biological, physical, and chemical methods of disease management.
Student Learning Outcomes:
- Identify diseases and species of insects, mites, slugs, and snails that are pests or natural enemies of pests in the greenhouse and nursery.
- Develop a scouting program for diseases and insects and mites in a greenhouse or nursery.
- Develop a management program for a specific greenhouse pest.
- Analyze disease incidence in a greenhouse and discuss cultural practices that contribute to successful management
- Apply best management practices for use of fungicides in the greenhouse and nursery.
