Brian Caldwell grew up on a farm in southwestern Manitoba and maintains strong ties to the farming community. After obtaining a Laboratory Technology Diploma from SIAST in Saskatoon, Brian spent his career at Ag Canada in Regina and Saskatoon, primarily in pesticide application with Tom Wolf.
For the past 25 years, Brian conducted research in spray drift, pesticide efficacy, canopy penetration, operator exposure, and sprayer tank cleanout. Brian now owns Agrimetrix Research & Training with Tom Wolf in Saskatoon. Together, they collaborate widely with universities and industry, and their research results are often quoted within the Canadian crop protection industry.
