Quick reference

Pesticide Regulation and Licensing in Ohio

  • Ohio pesticide law is administered by the Ohio Department of Agriculture (ODA); FIFRA sets the federal framework for registration, labeling, and restricted-use classification.

  • Private applicator license: required to apply or supervise restricted-use pesticides (RUPs) on land owned or rented by the applicator or employer for agricultural commodity production; issued by ODA.

  • Commercial applicator license: required to apply RUPs for hire or on property not owned/rented by the applicator or employer; categories (e.g., ag, turf, ornamental, structural) determine which applications are covered.

  • Pesticide business license: required for any business that applies pesticides for hire in Ohio; the business license is separate from the individual applicator credential.

  • Dealer requirements: persons selling RUPs must be licensed/registered as pesticide dealers and may sell RUPs only to licensed applicators or certified personnel.

  • Applicator credentials carry a defined recertification cycle; continuing education or re-examination is required before expiration to keep the license active.

  • Records of licensed applications and RUP sales must be maintained for the retention period set by ODA rule and made available on request during inspections.

  • Applying a pesticide inconsistent with its label (site, rate, method, or PPE) is a violation of both FIFRA and Ohio law and can result in license suspension or civil penalty.

Restricted-Use Pesticides and Sales Records

  • A restricted-use pesticide is one classified by EPA as available only to certified applicators or persons under their direct supervision because of acute toxicity or environmental hazard.

  • RUP sales require verification that the buyer holds a valid private or commercial applicator credential covering the product's use category; the credential number is recorded.

  • Required sales record elements typically include product name and EPA registration number, quantity sold, date of sale, buyer name and address, and buyer's certification/license number.

  • Dealers must retain RUP sales records for the period specified by ODA rule and produce them for inspection; records support enforcement traceability.

  • A private applicator may purchase and use RUPs only for agricultural production on owned or rented land; purchase for use on others' property requires a commercial credential.

  • Uncertified persons may use an RUP only when acting under the direct supervision of a certified applicator, per the product label's supervision statement.

  • EPA registration number format: three parts (company number, product number, distributor/alternate number), used to verify a product is registered and to match sales records.

  • Selling or distributing an RUP to an unlicensed buyer is a violation and can result in dealer license action and civil penalties.

Pesticide Product Registration and Distribution

  • A pesticide must be registered with EPA under FIFRA Section 3 before distribution or sale in the U.S.; ODA registers products for use in Ohio as well.

  • The label is the law: use must conform to the registered label directions, and any use not permitted by the label is a violation (with limited FIFRA exceptions).

  • Section 24(c) special local need registrations allow a state to add uses to a federally registered product for a specific local pest problem, with state and EPA review.

  • Section 18 emergency exemptions permit unregistered use for a limited time and defined area when no registered alternative exists; the exemption letter defines terms of use.

  • Experimental use permits (EUPs) allow limited testing of unregistered products under controlled conditions before registration.

  • Distributors and dealers must ensure products are properly registered and labeled; misbranded or adulterated products may not be sold or distributed.

  • Tolerances (maximum residue limits) must exist for pesticide residues on food/feed commodities; use inconsistent with a tolerance can render the crop adulterated.

  • Registration review under FIFRA periodically re-evaluates registered pesticides; label changes from review can alter permitted uses and rates.

Application Methods

  • Application rate = (product amount) ÷ (treated area); calibrate sprayers to deliver the labeled rate per acre (or per 1,000 sq ft for turf/ornamental uses).

  • Sprayer calibration formula: GPA = (GPM × 5940) ÷ (MPH × nozzle spacing in inches) for broadcast boom sprayers.

  • Nozzle selection and pressure control droplet size; finer droplets increase drift potential, coarser droplets reduce drift but may reduce coverage.

  • Drift management: use low-drift nozzles, lower boom height, buffer zones, and avoid application when wind favors off-target movement.

  • Band and directed applications reduce total product used versus broadcast; calculate rate based on band width relative to row spacing.

  • Granular applications require calibration of the spreader and consideration of swath overlap to achieve uniform coverage.

  • Tank mixing order and compatibility testing prevent clumping or antagonism; jar test before mixing unfamiliar combinations.

  • Application records must document method, rate, area treated, and conditions consistent with label requirements.

Quick reference

Aerial and UAS Application

  • Aerial application of pesticides requires a commercial applicator credential with the appropriate aerial category and, for aircraft, FAA pilot/operator compliance.

  • UAS (drone) pesticide application is regulated under FIFRA labeling and ODA rules; the label must permit aerial application for the intended use.

  • Aerial/UAS labels specify droplet size (often medium or coarser), boom height, wind speed limits, and buffer zones to reduce drift.

  • Aerial application rates are typically expressed per acre and require calibration of swath width and flow rate to match ground speed.

  • Aerial applicators must maintain records of each application including product, rate, area, date, time, and weather conditions.

  • UAS operators must verify the product label authorizes aerial application and follow any state-specific UAS pesticide application requirements.

  • Wind speed and direction, temperature inversions, and humidity affect aerial drift; applications are prohibited when conditions exceed label limits.

  • Aerial and UAS application records are subject to ODA inspection and must be retained for the required period.

Recordkeeping

  • Certified applicators must maintain application records for each RUP application; records include product name, EPA reg. number, rate, date, location, and applicator name.

  • Records must be kept for the retention period specified by ODA rule (commonly two years for RUP application records) and made available to ODA on request.

  • RUP dealer sales records must include buyer identity, credential number, product, quantity, and date, and be retained for the required period.

  • Application records should document target pest, site, weather conditions, and method to support label compliance and investigation traceability.

  • Records may be maintained electronically if they are legible, retrievable, and reproducible in a form acceptable to ODA.

  • Failure to maintain required records is a violation independent of the application itself and can result in license action.

  • Records of applications made by a business must be retained by the business and by the certified applicator responsible for the application.

  • Accurate records support recertification audits and demonstrate compliance during inspections or complaint investigations.
