3.2 Licence Categories & When Oregon Requires a Licence
Key Takeaways
- A licence is required to buy, apply or supervise restricted-use pesticides, to apply pesticides to another person's property, to apply by aircraft, and to apply on school campuses.
- No licence is required to apply general-use pesticides to property owned by you or your employer, except on school properties.
- Passing Laws and Safety is not enough; at least one category exam is also required, currently excepted only for the marine fouling organism category.
- Agriculture - Soil Fumigation II is limited to Commercial and Public licences, and the Regulatory Weed category is limited to Public Applicators, apprentices and trainees.
- The IPM in Schools law, ORS 634.700-750, requires school IPM plans and licensed applicators even for general-use and 25(b) organic products on school property.
Licence Categories & When Oregon Requires a Licence
Why this is on the exam: Passing Laws and Safety alone earns you nothing — ODA requires at least one category exam as well (the one current exception being the marine fouling organism category). Items in this area either name a job and ask for the category, or describe an activity and ask whether a licence is needed at all.
1. When Licensing IS Required
You need an Oregon pesticide licence when you are:
- Buying, applying or supervising the use of restricted-use pesticides, or advising others on RUPs;
- Applying pesticides to someone else's property — private or public land — outside the narrow exceptions in ORS 634.106;
- Applying pesticides as a public employee using machine-powered equipment and/or applying RUPs;
- Applying pesticides on school campuses;
- Applying certain pesticides — paraquat is the manual's example — that may only be applied by certified and licensed applicators;
- Applying any pesticide by aircraft, including fixed-wing, helicopter and unmanned aircraft systems;
- Applying unregistered pesticides for research under an Experimental Use Permit;
- Selling or distributing RUPs (a licence is required for each facility);
- Owning or operating a business, non-profit or organisation that advertises pesticide application services or whose employees must be licensed Commercial Pesticide Applicators.
2. When Licensing Is NOT Required
- Applying general-use pesticides to property owned by you or your employer. (A non-certified person applying RUPs must be supervised by a certified and licensed applicator and must have received handler training.)
- Public employees applying general-use pesticides with non-powered equipment — except on school properties.
- Advising others on general-use pesticides.
- Applying pesticides as part of landscape maintenance under very specific and limited conditions.
[!IMPORTANT] The two-part test. Almost every Oregon licensing item reduces to two questions: Is the product restricted-use? and Whose property is being treated? A grower applying a general-use herbicide to their own field needs nothing. The same grower applying an RUP to that field needs a Private licence. The same grower applying anything to the neighbour's field for hire needs a Commercial licence and an employing Operator.
3. Oregon's Licence Categories and Subcategories
Categories group related work; a category with several distinct areas of work is split into subcategories that share the main category title. Additional categories can be added to a licence at any time through the exam and application process.
| Category | Scope |
|---|---|
| Agriculture – Herbicide | Herbicides on agricultural lands (includes Christmas tree plantations and commercial nurseries) |
| Agriculture – Insecticide/Fungicide | Insecticides and fungicides on agricultural lands (includes Christmas tree plantations and commercial nurseries) |
| Agriculture – Livestock Pest | Pesticides for control of pests on livestock — insects, mites, ticks |
| Agriculture – Soil Fumigation II | Soil-applied fumigants on agricultural lands (Commercial and Public licences only) |
| Agriculture – Vertebrate Pest Control | Pesticides in agricultural areas for vertebrate pests other than livestock predators |
| Aquatic | Pesticides in standing or running water |
| Demonstration and Research | Pesticides for research and demonstration purposes |
| Forest | Pesticides in production of forest crops or on forestry lands (not Christmas tree plantations or commercial nurseries) |
| IIHS – General Pest | Non-fumigant pesticides in or around structures, institutions and establishments, protecting stored/processed/manufactured products or human health |
| IIHS – Structural Pest | Non-fumigant pesticides in or around structures for wood-destroying pests — termites, carpenter ants, powder post beetles |
| IIHS – Moss Control | Control of moss and algae on structures |
| IIHS – Space Fumigation | Fumigants in enclosed or confined areas or structures |
| IIHS – Wood Treatment | Treating wood products before use in construction, or field treatment of poles, pilings and bridge supports |
| Marine Fouling Organism Control | Anti-fouling paints or coatings on hulls and other parts of boats and ships |
| Ornamental & Turf – Herbicide | Herbicides in establishment and maintenance of ornamental plants and turf |
| Ornamental & Turf – Insecticide/Fungicide | Insecticides and fungicides in establishment and maintenance of ornamentals and turf |
| Public Health | Pesticides against any pest harmful to public health, including mosquito and other vector control |
| Regulatory Weed Control | Pesticides for control of designated noxious weeds (public applicators, apprentices and trainees) |
| Right-of-Way | Road shoulders, utility transmission lines, substations, equipment yards, irrigation ditch banks |
| School Integrated Pest Management | Pesticides on a school campus as defined in ORS 634.700, excluding power-driven equipment applications, wood-destroying pest / bed bug / lice / flea / tick / adult mosquito treatments, RUPs, total release foggers (except antimicrobial and insecticidal soap products), products not registered by ODA, and locations outside the school's adopted IPM plan |
| Seed Treatment | Pesticides applied on seed, including agricultural, flower and vegetable seed |
[!NOTE] Two licence-scope limits worth memorising. Agriculture – Soil Fumigation II is limited to Commercial and Public Pesticide Applicator licences. The Regulatory Weed exam is limited to the Public Pesticide Applicator licence. And within a Noncommercial Pesticide Applicator licence, the agriculture, forest and school IPM categories are available only to applicators employed by a private school.
4. The Oregon IPM in Schools Law (ORS 634.700–634.750)
Oregon requires public and private K-12 schools, community colleges and the other listed institutions to adopt and follow an integrated pest management plan, with a designated IPM plan coordinator. Applications on those campuses must be made by a licensed applicator holding the appropriate category — and the statute is why a Commercial or Public licence is needed even for general-use and 25(b) organic products on school property.
The law also governs notification and posting (ORS 634.740: written notice to staff and parents, warning signs), reentry (ORS 634.730, with a pest-emergency exception declared by the school), the low-impact pesticide concept (ORS 634.725), and a distinct four-year record retention period (ORS 634.750).
A public employee applies a general-use, ODA-registered insecticidal soap by hand-pump sprayer on the grounds of a public elementary school. Is a licence required?
Which Oregon licence category covers the use of pesticides other than fumigants in or around structures for the control of wood-destroying pests such as termites and carpenter ants?
Which Oregon licence category is available only to Public Pesticide Applicators, apprentices and trainees?
