What is BIOS?

Biologically Integrated Orchard Systems, or BIOS, is a whole-systems approach to farming that brings together growers, scientists, farm advisors, and pest control advisors with the goal of implementing farm practices to reduce dependence on chemical inputs. This approach utilizes comprehensive pest management practices that enhance natural pest control, reduce harmful insecticide sprays, and prioritize biological methods that are selective, low-risk, and effective.

History
The BIOS program was originally started in 1993 in partnership with CAFF, almond growers in Merced County, and the University of California Sustainable Agriculture and Research Program (UC SAREP). This collaboration paired on-farm demonstrations of biological practices with farmer-to-farmer information-sharing of their results. Following its success, this effort was expanded with the UC Cooperative Extension to walnuts in Yolo, Solano, San Joaquin, and Stanislaus counties. The BIOS model has since expanded to include other cropping systems and is now known as Biologically Integrated Farming Systems, or BIFS.

Needs Assessment

Want to participate but not farming in these regions?

Fill out our needs assessment survey!

  • We are gathering information on the integrated pest management (IPM) needs and barriers of stone fruit farmers in California. As pest dynamics have shifted in recent years, we hope to gather insight from farmers on prominent pest issues, barriers and challenges, topics of interest, and opportunities for future research.
  • Responses will be anonymous, compiled and shared with UC ANR (Division of Agriculture and Natural Resources).

Fill out the survey and enter to win a CAFF swag bag!

Includes: your choice of one CAFF shirt and one CAFF hat, an “I ♡ Cover Crops” bandana, a tote bag, stickers, and an annual CAFF membership!

Fill out the survey and enter the drawing by Dec 31st, 2026 for a chance to win.
