Has Aspergillus flavus been registered as an EPA pesticide active ingredient?

Aspergillus flavus holds an active EPA pesticide registration footprint across six distinct products, each listing it as an active ingredient under a specific registered strain. Growers, formulators, and compliance reviewers searching for 'Aspergillus flavus EPA registration' or 'Aspergillus flavus registered biopesticide' will find confirmed federal registry records spanning multiple registrant accounts and strain designations.

Three registrations are held by the Arizona Cotton Research and Protection Council under strain AF36, covering the products AF36, AF36 Prevail, and AF36 Prime (EPA reg. 71693-1, 71693-2, and 71693-3). Syngenta Crop Protection holds two registrations for strain NRRL 21882 — Aspergillus Flavus NRRL 21882 and Afla-Guard GR (EPA reg. 100-1468 and 100-1469). The Texas Corn Producers Board holds a sixth registration for strain TC16F under the product name Foursure (EPA reg. 91163-2).

The registry records confirm that EPA evaluates Aspergillus flavus registrations at the strain level rather than species-wide. Anyone verifying 'Aspergillus flavus EPA product registration number' or checking active biopesticide status can reference all six product records in the federal system.
