2026-2028 Catalog

Offered at: San Luis Obispo Campus

This program emphasizes both plant protection and plant production. Within the plant protection field of study, the student is exposed to a broad range of pest management subjects including entomology, plant pathology, and weed control. Within the production area the student may emphasize fruit production, crop production, ornamental horticulture, or natural resource management. Not open to Plant Sciences majors.

Program Learning Objectives

  1. Demonstrate technical competence in Plant Protection Science by identifying the majority of globally important food crops and demonstrating applications of theoretical sciences to their production, maintenance and post-harvest handling.
  2. Evaluate and adapt basic cultural practices, economic uses, and environmental interactions in the production of food, and fiber plants.
  3. Assess and implement appropriate sustainable growing based on region and microclimate, especially as they relate to water, soil and other natural resources.
  4. Practice a range of complex problem-solving exercises and excel in diagnosing and resolving plant health issues in outdoor and enclosed plant production systems.

Minor Requirements and Curriculum

The minor must be completed prior to, or at the same time as, the requirements for the bachelor's degree. A major and a minor may not be taken in the same degree program, and a minor is not required for a degree. Requirements for the minor include:
