Has Willaertia magna been registered as an EPA pesticide active ingredient?

Willaertia magna appears in EPA's APPRIL pesticide records as an active ingredient in four products, all from the registrant Amoeba Sa and all listing strain C2c.Maky. If you are searching for a Willaertia magna EPA registration, two of those four carry an active registration and two are marked inactive.

The active registrations are Amoeba Tgai (EPA reg. 91283-10) and Amoeba Ep #3 (EPA reg. 91283-11). The inactive ones are Amoeba Ep #1 (EPA reg. 91283-13) and Amoeba Ep #2 (EPA reg. 91283-12). Inactive registrations are not current, so only the two active products reflect a live EPA registration for Willaertia magna.

An EPA registration is precedent for the active ingredient. It is not an AAPFCO biostimulant determination, and these records do not say whether Willaertia magna is safe or effective for any particular use. They show registration status only.
