Valent BioSciences Acquires Mycorrhizal Applications Inc.

Valent BioSciences Corp. (VBC) has acquired Mycorrhizal Applications Inc. (MA), the world’s largest producer of mycorrhizal fungal inoculum.


Mycorrhizal inoculation increases plant productivity by forming a symbiotic relationship with plant roots. Mycorrhizal hyphae attach to roots and radiate out into soil, enhancing access to nutrients and water made available to plants.

The acquisition adds another strategic platform to VBC’s global biorational business, providing additional tools for the Biorational Window platform being developed with its parent company, Sumitomo Chemical Co. Ltd.

Founded in 1995 and headquartered in Oregon, MA’s earliest products were developed for forestry and nursery applications. Today, MA’s business has grown to include products for commercial agriculture, manufactured soils, turf, landscape, and restoration.

The company’s leading brand, MycoApply, is sold in powder, granular, and liquid form. Ted Melnik, VBC’s executive VP and chief operating officer, said a dedicated R&D budget earmarked for rhizosphere product development has been established to coincide with the acquisition.

VBC anticipates a host of new uses with widespread agricultural applications being developed in the next few years.
