Has Pseudomonas fluorescens been registered as an EPA pesticide active ingredient?

Pseudomonas fluorescens appears as an active ingredient in 9 pesticide products in EPA's APPRIL records. Of these, 5 carry an active EPA registration and 4 are inactive or cancelled. The records cover four strains: 1629RS, CL145A, D7 and ACK55.

The active registrations are Mbi-401 Tgai and Mbi-401 Sdp (strain CL145A, Invasive Species Corporation), D7 (strain D7, Verdesian Life Sciences U.S., Llc), and two USDA-ARS products, Pseudomonas Fluorescens Ack55 Technical and Battalion Pro (strain ACK55). The inactive ones are Frostban A and Frostban D (strain 1629RS, Frost Technologies), Moi-401 Ep (strain CL145A, Pro Farm Group, Inc.) and Fluorescens Technical (strain D7, Verdesian Life Sciences U.S., Llc).

If you are searching for a Pseudomonas fluorescens EPA registration, this is the precedent shown in the data: registered active-ingredient history, not a current registration for every listed product. An EPA registration is precedent for the active ingredient and is not an AAPFCO biostimulant determination.
