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

Pseudomonas chlororaphis appears in EPA's APPRIL records as an active ingredient in 5 pesticide products, so anyone searching for Pseudomonas chlororaphis EPA registration will find real registration precedent. Of those 5 products, 4 carry an active EPA registration and 1 is inactive.

The active products are Howler Technical (EPA reg. 70051-139), Howler (70051-141) and Howler T&O (70051-140), all registered to Certis USA, LLC with strain AFS009, plus Zio (67690-77) from Sepro Corporation, also strain AFS009. The inactive product is Ateze (EPA reg. 75801-2), registrant Turf Science Laboratories, Inc., strain 63-28.

Taken together, the data shows two strains: AFS009 across the four active products and 63-28 on the inactive one. An EPA registration is precedent for the active ingredient. It is not an AAPFCO biostimulant determination, and this record makes no claim about biostimulant status, safety, or efficacy.
