Regulatory Issues

​On July 29, 2022, the Oregon Department of Agriculture (ODA) filed a proposal to amend language in Oregon Administrative Rule (OAR) 603-057-0006. The proposal amended the rule by increasing the annual nonrefundable registration fee for each pesticide and each formula or formulation to $360.00, beginning the 2023 calendar year. This rule also proposed to make the fee nonrefundable.    

ODA held a virtual public hearing August 17, and public comments were accepted from 8 a.m. August 17 until 5 p.m. August 31, 2022,​ Pacific Time Zone​.​ Comments were reviewed and considered.

Update: The final permanent rule has been filed and is effective September 21, 2022. The language reads:


Pesticide Registration Fees

(1) The annual registration fee for each pesticide product for calendar year 2022 shall be $320.

(2) Beginning for calendar year 2023 pesticide product registration, the annual nonrefundable registration fee for each pesticide product shall be $360. ​​


EPA issued a final rule revoking all tolerances for the insecticide chlorpyrifos on Feb. 28, 2022. Lorsban or Dursban are some of the most common trade names for products containing chlorpyrifos.

EPA’s federal actions supersede ODA’s rule regarding use on food or feed crops. At this point, use on nonfood or nonfeed crops have not been impacted by federal actions. However, this is subject to change.

Bottomline: Do not use chlorpyrifos on any food or feed crops after Feb. 27, 2022.

Important: There may possibly be additional action on the federal level regarding product cancellations, sales and distribution. The details are unknown at this time, but ODA’s and EPA’s webpages will be updated periodically.​

Chlorpyrifos workgroup

The Oregon Department of Agriculture’s (ODA) Chlorpyrifos workgroup will advise the Department on potential limitations to the use of chlorpyrifos in Oregon beyond the limitations specified on product labels. The goal for this committee is to explore appropriate science-based restrictions on products containing chlorpyrifos that protect public health and safety while fulfilling critical pest control needs of land managers.

Members of the advisory committee include leaders and experts from a wide cross section of interests, including agriculture, environmental justice groups, and a farmworker health and safety organization. The committee's work will be transparent, collaborative and include inclusive communication, consistent with ODA’s mission and strategic plan objectives.
