|1. Description - |
|Problems of and control solutions for diseases, insects, and weeds in landscapes and gardens. Ecologically based Integrated Pest Management (IPM) practices for handling plant pathogens, insect infestations, and unwanted vegetation. Emphasis on identification, life cycles, and symptoms of diseases, insects, and weeds. This course is an elective for Horticulture certificates and degrees, and is intended for students in the horticulture program, but members of the public and professional community are invited to enroll.|
|Advisory: Completion of, or concurrent enrollment in, HORT 15 strongly recommended.|
|2. Course Objectives - |
|The student will be able to: |
- identify various plant pathogens
- through practical applications, demonstrate knowledge of insect morphology and biology
- through practical applications, demonstrate knowledge of plant morphology and biology
- through practical applications, demonstrate knowledge of general ecology of unwanted plants as well as their control.
- evaluate and choose the best methods to prevent and/or control plant diseases, insect infestations, and weed growth, including the selection of chemical and biological control agents.
- discuss local, state, and federal laws and regulations regarding pest management and the use of pesticides, insecticides, herbicides, and biological control agents utilized in IPM.
|3. Special Facilities and/or Equipment - |
|Horticultural laboratory, sustainable garden, and related horticultural facilities and equipment. Students provide equipment and supplies to collect and observe diseases, insects, and weeds including work boots, leather gloves and clothing for fieldwork. |
