Expediting the Review of Alternatives
to the Organophosphates


How does EPA prioritize its registration?

  • In Pesticide Registration (PR) Notice 97-2, EPA announced that it would prioritize pending applications in the registration queue utilizing the following criteria:

Alternatives to Methyl Bromide

"Reduced-Risk" Pesticides

USDA-EPA Vulnerable Crop/Pest Combinations

Minor Uses

Trade Irritants

Other Registrant-Identified Priorities

  • On its own initiative EPA amended these criteria, through PR Notice 98-7, to include non-"reduced-risk" alternatives to organophosphates (OPs), ranking such applications just below "reduced-risk" pesticides.
  • At the beginning of each fiscal year, EPA ranks the applications pending in its registration queue, using these criteria, and selects approximately 18 to 20 new conventional chemical decision candidates and approximately 250 to 275 new use candidates for evaluation.

How does EPA designate an application as an OP alternative?

  • Registrants typically must request OP alternative status by preparing an OP alternative rationale, as described in PR Notice 97-3. The rationale includes a registrant-prepared discussion of the following characteristics of the proposed alternative:

Human Health Effects

Ecological Effects and Environmental Fate

Risk Discussion, including aggregate and cumulative impacts (if known)

Comparative Risk Discussion with existing registered alternatives

Pest Resistance and Management

Comparative Product Performance (Efficacy Discussion)

Comparative Market Share Information

  • EPA’s "Reduced-Risk" Pesticide Committee evaluates these rationales and makes decisions about whether the registrant has effectively made a case that the proposed use presents opportunities for risk reduction and is likely to reduce the use of OPs.
  • The Agency welcomes input from growers in the identification of potential OP alternatives. In fact, the Agency has accelerated the reviews for some of the emerging OP alternatives based upon input from the user community.

What progress has EPA made in registering OP alternatives?

  • Since FQPA, the average registration timeframe for a new conventional "OP Alternative" is 23 months compared to 28-35 months for non-"reduced-risk"/non-"OP Alternative" conventional chemicals. The average registration timeframe for new uses for these chemicals is 13 months compared to 31-47 months for non-"reduced-risk"/non-"OP alternatives."
  • Only 4 of approximately 45 (10%) of the new conventional chemicals pending in the registration queue have been designated by EPA as "OP alternatives." EPA expects to complete its decision-making for these chemicals within the next 18 months, 2 by the end of December 2000.
  • Fewer than 100 of the more than 700 pending new use actions (less than 15%) have been designated by EPA as "OP alternatives." Most of these actions are likely to be completed within the next 18 months.
