Biopesticide Registration: EPA Biopesticide Division and EU Low-Risk Pathway
Biopesticides — microbial, biochemical and plant-incorporated protectants — follow registration pathways structurally lighter than conventional pesticides, on the rationale that the actives are naturally occurring or non-toxic by mode of action. EPA runs the Biopesticides and Pollution Prevention Division (BPPD); the EU runs low-risk active substance approval under 1107/2009 Article 22 and basic substances under Article 23. Timelines are 12–24 months versus 3–5 years for conventional actives, but the data requirements have tightened significantly in 2024–2026.

The three biopesticide categories: microbial, biochemical, PIP
EPA defines three biopesticide categories: microbial pesticides (bacteria, fungi, viruses, protozoa — Bacillus thuringiensis, Trichoderma harzianum, baculoviruses), biochemical pesticides (semiochemicals, plant extracts, growth regulators with non-toxic mode of action) and plant-incorporated protectants (PIPs — actives expressed in genetically modified plants, regulated jointly with USDA APHIS). EU 1107/2009 uses similar groupings with low-risk and basic substance designations layered on top.
Microbial identification and strain characterisation
Microbial biopesticide registration hinges on strain identity. EPA requires 16S rRNA (bacteria) or ITS (fungi) sequencing, MALDI-TOF confirmation, and deposit in an International Depositary Authority under the Budapest Treaty. EU EFSA QPS (Qualified Presumption of Safety) status for the species is a major accelerator. The recurring failure: a production lot that drifts from the registered strain — caught when EFSA or EPA re-sequences a market sample and the SNP profile no longer matches.
Production GMP and microbial contamination control
Biopesticide production must meet EPA establishment requirements and, increasingly, ISO 9001-anchored microbial GMP. Contamination control is the central QMS challenge: a Bacillus thuringiensis fermentation contaminated with Bacillus cereus shares 99% genome identity but is enterotoxin-positive — the analytical method must discriminate. EPA's 2024 BPPD guidance and EFSA's microbial pesticide draft both elevate the absence-of-relevant-secondary-metabolites requirement.
Low-risk and basic substance designations: EU specifics
EU 1107/2009 Article 22 grants low-risk status to actives meeting Annex II point 5 criteria — non-CMR, non-ED, no PBT, biodegradable, no concern for resistance development. Approval period is 15 years instead of 10, and product authorisation is faster. Article 23 basic substances (e.g., vinegar, baking soda, sucrose) are approved without active-substance dossier but require an application demonstrating the substance is not predominantly used as a plant protection product. Approved low-risk and basic substance lists are maintained by DG SANTE.
A 75-day biopesticide readiness path
Days 1–15: confirm strain identity at production scale (16S/ITS, MALDI-TOF, SNP); reconcile with the deposited strain. Days 16–30: rebuild fermentation environmental monitoring against the registered strain identity and the relevant-contaminant list. Days 31–50: refresh the EPA BPPD or EU low-risk dossier; close data gaps against current 2024–2026 guidance. Days 51–65: stress-test the lot release workflow against a contamination event. Days 66–75: rehearse an EPA BPPD or EU member state inspection from the file pack.

Frequently asked
Is biopesticide registration cheaper than conventional?
EPA fees are lower (BPPD PRIA fees roughly 25–40% of conventional), and timelines are shorter (12–24 months vs 3–4 years). The data package, especially strain characterisation and absence of secondary metabolites, has tightened in 2024–2026.
Can a fermentation contractor hold the EPA establishment number?
Yes — the producing establishment holds the Section 7 establishment number regardless of whether the registrant or a contract manufacturer owns the facility. The registrant must hold the supply agreement and the strain identity binding.
Are RNAi biopesticides regulated as microbials?
No. RNAi-based pesticides (double-stranded RNA actives) are conventional pesticides for EPA conventional registration purposes when applied externally; PIPs when expressed in planta. EU treats them as plant protection products under 1107/2009 with specific safety endpoints.
Does USDA NOP allow registered biopesticides?
Many — see the OMRI listing and the USDA NOP National List (7 CFR 205.601). Microbial biopesticides without prohibited inerts and most biochemical pesticides qualify.
