For more than 30 years, Mycorrhizal Applications has been committed to advancing the science of mycorrhizal fungi and other biorational solutions, helping growers, retailers, and horticulture professionals sustainably improve plant and soil health.
As part of our continued investment in the future of our business, we have transitioned our mycorrhizal fungi operations to our new production hub in White City, Oregon.
Purpose-built to support the future of our mycorrhizal fungi business, the White City facility brings together advanced production capabilities and modern process systems designed to advance innovation, operational excellence, and long-term growth. From the earliest planning stages, the facility was designed with sustainability in mind and incorporates advanced process technologies that will support our global mycorrhizal fungi business for years to come.
In addition to our new production hub in White City, we continue to work with a trusted, long-term partner in Osage, Iowa, to provide formulation, packaging, and additional manufacturing support. Product will continue to ship from Osage.
Building for the Future
The demand for mycorrhizal fungi and other biological products continues to evolve, creating new opportunities to help growers and horticulture professionals improve plant performance while supporting healthy soils and more resilient production systems.

Our investment in White City reflects our long-term commitment to meeting those evolving needs. The facility expands our capabilities for producing arbuscular mycorrhizal fungi using advanced production methods, while strengthening our ability to support future innovation across our product portfolio. These investments position the organization to continue serving customers today while preparing for the next generation of biorational technologies.
Together, our White City and Osage operations create an integrated manufacturing network designed to support the growing demand for mycorrhizal fungi products while maintaining the product quality and consistency our customers expect.
Backed by Experience
Since our founding in 1995, Mycorrhizal Applications has built a reputation for scientific expertise, product quality, and technical support. As part of Sumitomo Biorational (formerly Valent BioSciences), we continue that legacy with the strong backing of a global organization dedicated to advancing sustainable solutions for agriculture, horticulture, forestry, public health, and environmental markets. Together, we are continuing to invest in the research, manufacturing capabilities, and scientific expertise needed to help our customers succeed well into the future.
Our Commitment Remains
While our production capabilities continue to evolve, one thing has not changed: our commitment to our customers.
We remain focused on delivering the trusted mycorrhizal products, technical expertise, and customer support that distributors, retailers, growers, and industry partners have trusted for decades.
From our production hub in White City, we look forward to continuing our mission of advancing mycorrhizal science and helping customers unlock the full potential of healthier plants and healthier soils.
