About Us: Who We are

With a focus on soil health and expertise in pest management, Tri-Tech Ag Products advisors can help bring in a bountiful crop while protecting the environment and improving agricultural sustainability. We integrate several pest management strategies to keep threatening pest populations below economic injury levels and we apply appropriate fertilizers to improve soil quality and support a thriving microbial population in the root zone. By building and maintaining soil organic matter, we enhance soil fertility and produce stronger plants, better equipped to defend themselves against pests and pathogens. Our team of PCAs and CCAs work together to develop efficient and sustainable agricultural management practices. With different experience levels and educational backgrounds, each of us contributes a unique skillset and perspective on problem solving. We make a dynamic and well-rounded team by balancing new scientific knowledge and technology with many years of field experience managing pests in Ventura County.
