About the Plant Science Discipline
Get your hands dirty while you learn about the science of developing and growing crops and ornamental plants. Use our greenhouse and field facilities to examine how environmental conditions, soil, nutrients, and pests all affect plant growth and development.
Certificates in Plant Science
The Plant Protection Certificate of Achievement prepares students to design and implement comprehensive integrated pest management programs for private or public entities. Pest Control Advisers (PCA) provide written recommendations for the application of pesticides, as well as providing guidance to farmers for overall plant health. This certificate satisfies the core-course requirements specified for option “3. b” in preparing to take the Pest Control Adviser’s exam with the California Department of Pesticide Regulation. The following courses need to be completed with a 2.0 grade point average or better.
Note: In addition to completing the course work, the Department of Pesticide Regulation requires PCA exam applicants to have completed 24 months of technical work experience before taking the exam. Courses in the program provide hands-on experiences designed to give students a combination of practical skills and technical knowledge. Students who intend to transfer should meet with a counselor or advisor to review lower-division requirements of the college or university they plan to attend.
Program maps suggest courses to take by semester and include career and transfer information when available.
