Mycorrhizal Applications is the master distributor for a suite of biorational plant health products like biofungicides, botanical insecticides, and plant growth regulators. And, as the world’s leading manufacturer and supplier of mycorrhizal soil inoculants, Mycorrhizal Applications researches and produces mycorrhizal fungi.

Science Helping Your Plants Grow Better Naturally!

Our Philosophy

Mycorrhizal Applications is a company that is committed to Mother Earth, customer service, quality products, sound science, sustainable progress, and ultimately, our goal to “Change Your World.” We believe that the people who are crazy enough to think they can change the world are the ones who do, and we are just that kind of crazy.

As the world’s largest producer of beneficial mycorrhizal fungi, we are proud of the contribution our MycoApply® products are making to improve the sustainability of our planet, the nutritional quality of food, and the ability to feed our growing population, while reducing the need for petrochemicals and fossil fuels, as well as lowering the need for irrigation, and ultimately reducing erosion and pollution of our water resources and improving plant establishment on degraded and even desertified lands. By respecting, honoring, and promoting the natural symbioses that plants rely upon in nature, we are re-establishing, promoting, and supporting living soils worldwide.

Mission: At Mycorrhizal Applications, we harness the power and wisdom of natural systems to promote living soils and increase quality, productivity, and health in all industries involving soils, plants, and people.

Company History

Mycorrhizal Applications was founded in 1995 by Dr. Mike and Eileen Amaranthus, with a focus on producing ectomycorrhizal slurries for use in forest restoration. The company subsequently developed “in vivo” and “in vitro” methods for producing a diverse array of mycorrhizal products for use in many applications, including agriculture, turf management, landscaping, and professional horticulture.
