Has Nosema locustae been registered as an EPA pesticide active ingredient?

Nosema locustae appears as an active ingredient in 5 pesticide products in EPA's APPRIL records, which makes it a useful reference point for anyone searching for Nosema locustae EPA registration. Only 1 of those products carries an active registration. The other 4 are marked inactive or cancelled.

The active product is Semaspore Bait (Organic Fanatics Biologics, LLC, EPA reg. 95566-1). The inactive registrations are Mormon Cricket Spore and Grasshopper Attack (both Woodstream Corporation, EPA reg. 36488-7 and 36488-3), plus Nolo Bb Concentrate and Nolo Bait (both M&R Durango, Inc, strain Canning LM, EPA reg. 46149-1 and 46149-2).

An EPA pesticide registration is precedent for the active ingredient. It is not an AAPFCO biostimulant determination, and this record does not show an approved label claim. Check the registrant's current label before relying on any of these products.
