3.1 Oregon Pesticide Licence Types

Key Takeaways

  • Certification is passing the required exams; licensing is the permission to work, and no application may be made until the licence is issued.
  • A Commercial Pesticide Applicator must be employed by a licensed Commercial Pesticide Operator, and ODA may not issue an Operator licence to a public agency.
  • ORS 634.116(6) requires operator financial responsibility of not less than $25,000 for bodily injury and not less than $25,000 for property damage.
  • An Immediately Supervised Trainee's supervisor must be on site and reachable within five minutes; a Pesticide Apprentice's supervisor need only be reachable at all times.
  • Except for Private Applicators, all Oregon pesticide licences expire December 31 and renew annually.

Oregon Pesticide Licence Types

Why this is on the exam: "License types and requirements" is an explicit leaf of Domain 4, and the Addendum's Chapter 2 review questions are almost entirely licence-matching scenarios: "What licence type would a farmer need in order to legally apply a restricted use pesticide to his field, orchard, forest or nursery?" Learn the licences by who employs you and whose property you treat.


1. Certification Is Not Licensing

Oregon separates two processes, and mixing them up costs points:

  • Certification is demonstrating competence — you become certified by passing the required examinations. For Commercial, Public, Private applicators and Consultants, the certification period begins the day after you pass the required exam(s), and it runs even if you never apply for the licence.
  • Licensing is the permission to work. You obtain a licence by (1) passing any required exam(s), (2) submitting the application form, (3) paying the fee, and (4) meeting any other requirements. You may not make pesticide applications until the licence has been issued.

Trainees and Apprentices are not certified applicators and therefore have no certification period — but they still must be licensed.

Commercial Pesticide Applicator (CPA)

The individual for-hire applicator. A CPA may:

  • Apply or supervise the application of any pesticide — general use, restricted use, and 25(b) products including products considered organic — on the land or property of others;
  • Apply RUPs to non-agricultural land belonging to themselves or their employer;
  • Apply general-use pesticides (including organic and 25(b) products) on the property of any Oregon pre-kindergarten, public or private K-12 school, community college, federal Head Start programme, Oregon School for the Deaf, Oregon Youth Authority residential academy, or education service district, under the IPM in Schools law (ORS 634.700–750);
  • Supervise an Immediately Supervised Trainee or a Pesticide Apprentice;
  • Provide technical advice on RUPs within the categories listed on the licence;
  • Solicit to apply pesticides to someone else's property, even with no charge.

To make or supervise applications under this licence you must be employed by a licensed Commercial Pesticide Operator. Required exams: Laws & Safety plus at least one category exam.

Commercial Pesticide Operator

The business that applies pesticides to the property of others. If the business is a corporation, at least one employee must hold a CPA licence; if it is a sole proprietorship or partnership, the owner or a partner must. The operator's pesticide activities are limited to the categories held by both the operator and the applicator it employs. The business must provide proof of insurance. ODA may not issue a Commercial Pesticide Operator licence to a public agency. Required exam: none.

Public Pesticide Applicator

For employees of federal and state agencies, counties, cities, municipalities, irrigation and drainage districts, soil and water conservation and other special districts, public utilities and telecommunication utilities who in the course of their work use or supervise the use of RUPs, use machine-powered equipment to apply any pesticide, or apply pesticides on school-type properties. A public applicator may not function as a Commercial Pesticide Applicator. Non-profits are not public employers. Required exams: Laws & Safety plus at least one category exam.

Private Pesticide Applicator

Needed to purchase, apply or supervise the use of RUPs on land in agricultural production that the person or their employer owns, leases or rents — farmland, rangeland, forests, greenhouses, nurseries, orchards. No licence is required to apply general-use pesticides on that land. The licence and certification run up to five years. Required exam: Private Pesticide Applicator (available in English and Spanish).

Pesticide Consultant

For a person who provides technical information on restricted-use pesticides. It is not an applicator licence. Required exam: Pesticide Consultant.

Pesticide Apprentice

Works under the supervision of a Commercial or Public Applicator, within the supervisor's categories. The supervisor does not have to be on site, but the Apprentice must be able to reach the supervisor at all times. An Apprentice is not certified and cannot purchase RUPs. Required exam: Laws & Safety.

Immediately Supervised Pesticide Trainee

Works under the immediate supervision of a Commercial or Public Applicator, within the supervisor's categories. The supervisor must be on site at all times during applications and able to reach the trainee's location within five (5) minutes. Not certified; cannot purchase RUPs. Issued for up to one year and renewable annually. Required exam: none.

Aerial Pesticide Applicator

Required for any application by aircraft, including UAS/drones. The individual must also hold a Commercial, Public or Private Applicator licence, must have 50 or more hours of aerial application experience, and since January 1, 2017 must pass the Aerial Applicator exam. Categories are limited to those on the underlying applicator licence.

Pesticide Dealer

Required for each facility that sells, offers for sale, handles, displays or distributes RUPs to pesticide users. Dealers must keep RUP sales and distribution records for three years (OAR 603-057-0140). Required exam: none.


3. Financial Responsibility — the Numbers That Matter

Under ORS 634.116(5)–(6), a Commercial Pesticide Operator must furnish evidence of public liability protection through an insurance policy, or an acceptable equivalent such as a cash deposit or surety bond. The statutory minimum is:

not less than $25,000 for bodily injury to one or more persons\textbf{not less than } \$25{,}000 \text{ for bodily injury to one or more persons} and not less than $25,000 for property damage\textbf{and not less than } \$25{,}000 \text{ for property damage}

Under ORS 634.116(7), if the operator fails to maintain that financial responsibility, the licence is automatically suspended — no separate administrative proceeding is required.


4. Minimum Age

  • 18 to obtain a Commercial, Public, Apprentice or Immediately Supervised Trainee licence (ORS 634.122, 634.116, 634.126).
  • 16 is currently the minimum age for a Private Pesticide Applicator licence in Oregon; federal certification rule changes are expected to raise it to 18.

5. Licence Period and the 45-Day Rule

With the exception of Private Applicators, all licences expire December 31 each year and renew annually. One quirk is regularly tested: if ODA receives a licence application in the last 45 days of the year (November 17 – December 31) and you qualify for a licence in the following year, ODA issues a licence covering the remainder of that calendar year plus the entire next calendar year.
