Oklahoma pesticide and fertilizer record rules for lawn care companies

Last reviewed October 11, 2026 · 8 min read

The short answer

In Oklahoma, commercial applicators keep a record of every pesticide they apply, general use as well as restricted use: the start and stop time, the total amount used, the company’s name and address, the certified applicator who made or supervised the application with their certification number and certification expiration date, and any noncertified applicator under direct supervision, the customer’s name and address, the legal description or street address of the land, the date, the application rate, the dilution rate, the total quantity of tank mix used, the complete trade name, the EPA registration number, label-required adjuvants and drift agents, the target pest, the site, the size of the area treated, the label’s restricted entry interval, a copy of the label, and copies of any contracts issued. Keep records at the principal business location in Oklahoma for at least two years after their date of expiration, and give a summary within seven working days of a written request. Oklahoma’s rules have no lawn sign or customer notice requirement for turf.

General information, not legal advice. Rules change and can depend on what you apply and where. Confirm what applies to your business with the Oklahoma Department of Agriculture, Food and Forestry, Consumer Protection Services and the product label before you rely on anything here.

Who regulates lawn care applicators

The State Board of Agriculture administers and enforces the Oklahoma Combined Pesticide Law (2 O.S. §§ 3-81 to 3-86), and the Oklahoma Department of Agriculture, Food and Forestry’s Consumer Protection Services Division oversees applicator licensing, certification, continuing education and complaints. The Board’s pesticide rules are OAC 35:30-17 (“Combined Pesticide”), last amended effective July 11, 2026.

“Commercial application” means advertising services, recommending use, preparing for application, or physically applying a pesticide or using a device for hire or compensation. No city, town, county or other political subdivision may adopt or keep any ordinance, rule or regulation on pesticide sale or use that is more stringent than the Board’s rules, including on notification and posting; the only exception is a stricter standard the Board permits when a political subdivision needs it to comply with federal requirements.

Any use inconsistent with the label is prohibited without the Board’s prior written approval, and failing to follow the label’s precautionary and recommended language may be treated as such a use. Failure or refusal to keep complete and accurate records is grounds for suspending, cancelling, revoking or refusing a license, certificate or identification. After notice and a hearing, the Board may assess an administrative penalty of $100 to $10,000 for each violation, and a violation of the Combined Pesticide Law is a misdemeanor punishable by a fine of $100 to $10,000, 30 days to one year in county jail, or both.

Licenses you need

Business license: it is unlawful to act, operate, do business or advertise as a commercial applicator, certified applicator or service technician without a valid license from the Board for the category of work, unless applying to one’s own property. Licenses are issued to the business: each business location needs its own license and its own certified applicator, certified in each category licensed at that location. A business operating under more than one name from one location (a trade name, d/b/a, website or alias) must be licensed separately for each name.
Category 3a, Ornamental and Turf Outdoor Pest Control, covers pesticide applications to lawns and ornamental trees and shrubs in residential or business areas, including parks, golf courses and other recreational areas.
Fees and renewal: the commercial license fee is $100 per category, with no more than $500 a year for any business location. Licenses for businesses whose names begin with a number or A through L expire September 30, and those beginning with M through Z expire December 31; a late renewal costs twice the fee, plus $100 more if it arrives after November 1 or February 1.
Insurance: before a business license is issued, the business must file a certificate of insurance of at least $50,000 bodily injury, $100,000 bodily injury per occurrence and $50,000 property damage, covering damage including chemical drift or trespass, with each initial and renewal application. The insurance must be kept in force all through the license period, the insurer must notify the Board 15 days before a reduction or cancellation, a deductible may not exceed $5,000, and applying a pesticide the policy excludes counts as working without a license.
Certified applicator: pass a Phase I general exam and then a Phase II category exam within 12 months, each with a score of 70% or more. A certificate is valid for five years, and certified applicators recertify every five years by passing the Phase II exam again or earning continuing education units (CEUs). Category 3a requires 20 CEUs in five years, no more than 10 in any one year, earned in at least three of the five years. ODAFF says each category recertifies on a fixed five-year schedule that does not depend on when the person was certified.
Service technician: an employee of a licensed applicator who applies pesticides but is not a certified applicator. A service technician is certified by passing a written service technician exam; the identification is issued in the name of the licensed business, is valid for five years or until the technician leaves, and the business must return it to the Board when the employee leaves. The fee for issuing or renewing a service technician identification is $20.
Listing on the license: since July 11, 2026, every applicator working for a company must be listed on the company’s license before making any applications. The license application lists every certified applicator with their certified applicator number and every service technician with their service technician number, and new service technicians are added with the service technician identification form.
Age: certified applicators, noncertified applicators and service technicians must be at least 18 years old to make pesticide applications.

A service technician or a certified applicator must be present at each application. A certified applicator must be on site to supervise any application by a person who is not a service technician, and whenever the label requires it; a service technician must be on site to make the actual application unless a certified applicator is at the job site. Under direct supervision, the certified applicator is responsible for making sure the people supervised are qualified and instructed in the specific pesticides used, and must be reachable by telephone, radio or another approved device at all times during the application.

A noncertified applicator must receive approved safety training before applying a restricted use pesticide, and the employer keeps a record of it for at least two years: the applicator’s printed name and signature, the trainer’s name, the date completed and the title or description of the training.

On the job: every vehicle a commercial applicator uses in the business must show the licensee’s name and license number on both sides in letters at least 2 inches high. Every container used to apply a pesticide must be accompanied by a readable copy of the label, attached to the container or kept on or in the vehicle carrying it, and every applicator must use a check valve, air gap or similar method to prevent backflow while filling, mixing or applying.

What to record for each application

Under OAC 35:30-17-21, commercial and noncommercial applicators must keep accurate records of their pesticide activities, which covers every pesticide they apply, general use as well as restricted use (private applicators record restricted use only). Each record holds:

The start and stop time of the application
The total amount of pesticide used
The name and address of the commercial or noncommercial company
The name, certification number and certification expiration date of the certified applicator who made or supervised the application, and the name of any noncertified applicator working under direct supervision
The name and address of the person for whom the pesticide was applied
The legal description of the land where applied, which may be a street address if properly marked but not a post office box
The date of application
The application rate
The dilution rate for mixing
The total quantity of tank mix used
The complete trade name of the pesticide product used
The EPA registration number of the product used
The names of adjuvants used, when the label requires specific adjuvants, and of drift agents used, when the label requires specific drift agents
The target pest
The site where the pesticide was applied
The size of the area treated
The restricted entry interval as stated on the product label
A copy of the product label or labeling attached to the container or included in the shipping case
Copies of any contracts issued (any contract, not only structural ones; contracts are required only in the Structural Pest Category) and of any wood infestation reports issued (structural work); the Board may also require other information

The record rule lists no weather item and sets no deadline by which the record must be written. The certification number and expiration date asked for are the certified applicator’s own, not the business license’s: Oklahoma licenses the business and certifies the person.

How long to keep records and who can ask for them

Keep records intact at the principal business location in Oklahoma for at least two years after their date of expiration, as the statute words it.
Records must be easily accessible to the Board’s agents during reasonable business hours and kept at the principal place of business, which may not be in a closed gated community or a residence unless the Board approves a plan of access.
Give copies to an authorized agent of the Board immediately on request in person during regular business hours, and within seven working days of a written request, in summary form by mail, fax, e-mail, website or other electronic means.
The Board may inspect any work, records or contracts of an applicator, and its agents may enter premises during normal business hours to examine and copy records of pesticide applications.
ODAFF investigates complaints of pesticide misuse, such as drift from lawns, filed on its Pesticide Complaint Statement, and its investigation reports are subject to the Oklahoma Open Records Act.

Spills: an uncontained spill of more than 10 gallons of liquid or 25 pounds dry weight of pesticide concentrate, or 50 gallons of tank mix, must be reported within 24 hours by telephone and by written notice within 3 days to the Oklahoma Department of Environmental Quality and ODAFF’s Pesticide Section; a spill or backflow of any amount into a public water supply system must be reported to ODAFF within 24 hours, and the person pays all cleanup costs.

Customer notice, posting and lawn signs

OAC 35:30-17 has no customer notice, neighbor notice or lawn sign rule for turf and ornamental applications. Its only notice and posting rules are for structural fumigation (telling local law enforcement and the fire department, written notice to dwellings and businesses within 10 feet, and warning signs) and the notice posted after a wood infestation inspection. Cities and counties may not adopt notification or posting rules stricter than the Board’s. Label-required posting still applies.

Since July 11, 2026, before a contract is signed all service terms, including the cancellation policy, must be clearly explained to the customer, and a copy of the contract must be given to the customer when it is signed.

ODAFF runs a Sensitive Crop Registry and Sensitive Crop Viewer, a voluntary online map where growers register sensitive crops. The registry account is not tied to any license, and no rule requires applicators to check it or notify registrants.

Fertilizer rules

The Oklahoma Fertilizer Act (2 O.S. §§ 8-77.1 to 8-77.18) is administered by the State Board of Agriculture, and its purposes include regulating the storage, use and application of fertilizer. Under the Act, “distribute” includes commercially applying fertilizer. Fertilizer dealers, meaning businesses engaged in distributing or selling fertilizer (but not an ultimate consumer who applies it), need a license for each business location at $50 a year. ODAFF says any business engaged in the distribution, use or sale of commercial fertilizer must get a license for each business location, except an ultimate consumer applying it and a retail store selling only bagged registered fertilizer.

A lawn care or tree service company that mixes a custom blend to the customer’s specifications given before mixing, and applies it for that customer, does not have to register each grade of the blend, but a custom blender must be licensed and is the guarantor of the blend. Each fertilizer registrant, distributor or manufacturer must keep accurate records of the tonnage of fertilizer it distributes in Oklahoma, a tonnage record rather than a record of each application.

The Fertilizer Act and its rules set no applicator license, per-application record, nitrogen or phosphorus limit, blackout dates or application setbacks for turf; their setbacks apply to storage tanks. Fertilizer may not be stored, applied or handled in a way likely to pollute the air, land or water, and the responsible party pays for cleanup of any spill or pollution. The Act preempts cities and counties on fertilizer registration, labeling, sale, storage, distribution and agricultural use or application, but leaves room for local rules on nonagricultural use or application.

How GroundsQuote’s chemical records line up

GroundsQuote keeps an application record for each chemical a crew puts down on a job. On a job at a property in Oklahoma, Finish job asks the crew for the details Oklahoma lists, and the records export with the columns in Oklahoma’s order. Here is each item Oklahoma lists, set against what the record actually holds. Keeping the record complete and correct is still your responsibility.

Oklahoma record items and GroundsQuote’s chemical application record
Oklahoma asks for	In GroundsQuote	Status
Start and stop time of the application	Start and finish time for each chemical, offered on Oklahoma jobs; left blank, a chemical carries the job’s start and finish times, recorded when the crew starts and finishes it (the office can correct them)	Recorded
Total amount of pesticide used	Total used	Recorded
Name and address of the commercial company	Your business name, address and phone (export columns; also on the application statement)	Recorded
Certified applicator who made or supervised it: name, certification number and certification expiration date	Applied by and Supervised by (offered on Oklahoma jobs), with each person’s certification or ID number and expiry when license-keeping is switched on; one expiry date is kept per person, so enter the certification’s, not the business license’s	Recorded
Name of any noncertified applicator under direct supervision	Applied by, with each person’s standing (registered technician, trained, not certified or registered), and trainees on the job’s record (offered on Oklahoma jobs)	Recorded
Name and address of the person for whom it was applied	Customer name and mailing address	Recorded
Legal description of the land, or a properly marked street address (not a post office box)	Street address, unit, city, state, ZIP and county	Recorded
Date of application	Date and time applied	Recorded
Application rate	Rate applied (per area)	Recorded
Dilution rate for mixing	Mix ratio and use dilution (%), set on the job; the mix is required on Oklahoma jobs at Finish job	Recorded
Total quantity of tank mix used	Water or carrier and gallons of mix applied, set on the job and required on Oklahoma jobs at Finish job	Recorded
Complete trade name of the product	Product name, as entered in the chemical’s setup	Recorded
EPA registration number	EPA Reg. No., from the chemical’s setup	Recorded
Adjuvants and drift agents, when the label requires specific ones	A chemical line for each product (an adjuvant or drift agent must be set up as its own chemical), and “Other records the label requires”, offered at Finish job on Oklahoma jobs	Partly
Target pest	Target pest, set for each chemical on the job	Recorded
Site where the pesticide was applied	Where on the property (front lawn, beds, fence line… or a description), required on Oklahoma jobs at Finish job	Recorded
Size of the area treated	Area treated in sq ft	Recorded
Restricted entry interval as stated on the label	Re-entry interval from the chemical’s setup, with the time people may go back onto the lawn	Recorded
Copy of the product label or labeling	A copy of the label on file for each chemical (earlier files kept when replaced), only when one is uploaded; GroundsQuote does not require one, and Finish job on Oklahoma jobs reminds you to keep a copy of each product’s label with the records	Partly
Copies of any contracts issued	Signed contracts kept on the customer’s page with a copy of the paper, and the accepted quote with its terms and notices; kept per customer, not tied to each application record	Partly
Copies of wood infestation reports issued	Not kept: structural work, not lawn care	Not recorded
Noncertified applicator’s restricted use training record (printed name and signature, trainer, date, title), kept 2 years	Training and ID records for each person, with a copy of the paper; a signed sheet can be attached, but GroundsQuote captures no signature itself and does not track how long it is kept	Partly
Every applicator listed on the company’s license before making applications	Not handled by GroundsQuote: Finish job on Oklahoma jobs reminds you of it; GroundsQuote keeps each person’s standing and number but files nothing with ODAFF and does not check who is on the license	Not recorded

Upload a copy of each chemical’s label so it sits with the records, and set up label-required adjuvants and drift agents as chemicals of their own. Outside GroundsQuote, keep the records at your principal business location (with a plan of access for a home or gated community), list every applicator on the company license and return a technician’s identification when they leave, and handle license renewals, recertification and CEUs, the certificate of insurance, vehicle lettering, labels with every container, backflow prevention, spill reports to DEQ and ODAFF, and the Sensitive Crop Registry. GroundsQuote keeps records indefinitely and tracks no retention date, and it does not warn when nobody certified or registered as a technician is on the job.

Everything a GroundsQuote application record holds

When:: Date and time applied (when the job was finished), job start and finish times (the office can correct them), each chemical’s own start and finish when several go down on one job, and when people may go back onto the lawn (from the label’s re-entry interval)
Where:: Customer name, phone and mailing address, street address, unit number, city, state, ZIP and county of the property, and where on the property it went (front lawn, beds, fence line…)
Who:: Everyone who applied it (the crew riding that day starts checked) and the person supervising, trainees and people who planned it, with each one’s standing (certified, registered technician, trained, not certified or registered), license number, certification or ID number, category and expiry, and the business license when license-keeping is switched on
Product:: Name, type, manufacturer, EPA registration number, state registration number, EUP / Section 18 / 24(c) number, active ingredients, scientific name, concentration, N-P-K and slow-release %, formulation, restricted-use flag, signal word, re-entry interval, the label’s precautions, and copies of the label, safety data sheet and fact sheets on file
Amounts:: Rate applied (per area), area treated in sq ft, total product used, mix ratio, use dilution (%), water or carrier (gallons, and the carrier when it is not water), gallons of mix applied, devices placed, lb of N and P per 1,000 sq ft
Job:: Target pest and the equipment used (both set on the job), the vehicle or sprayer’s license plate, where it was mixed and loaded, permit number, other records the label requires, the supervisor’s instructions, whether the drift plan was used, a review sign-off with the reviewer’s license number and corrective action, a map of the treated area attached to the job, service and crew; your business name, address and phone
Weather:: From the nearest weather station at the start and finish (temperature, humidity, wind speed and direction, gusts, rain in the last hour, conditions), and the conditions on site: the crew confirms the station reading or enters the wind, direction and temperature they measured
Your state:: Each job follows the rules of the state its property is in: Finish job asks for the details that state lists and waits until they are filled in, and the records export in that state’s column order
Paperwork:: An application statement for each job to print, leave or email (each product with its EPA number, active ingredients, type, purpose, rate, amount and mix, where on the property, the date and time, who applied it, the re-entry time and your notes for the customer, with the state’s own lines), and lawn signs laid out from the state’s rule
Kept beside the records:: Each person’s training, ID copies and certificates and what they are responsible for; neighbor requests and notices, registry notices and attempts, notices given to customers, signed waivers and contracts, each with a copy of the paper; soil tests per property; incidents, disposal and purchases in the chemical logs; totals for a year or a month by county, supervisor or product; whether a customer agreed in writing to get application information by email
Changes:: Corrections are saved as history; the earlier record is kept
Reminders:: Finish job reminds the crew of the state’s own steps (a record deadline, trainee paperwork) and warns when a restricted-use chemical has nobody certified applying or supervising it; the schedule lists chemical jobs left without a record in states with a deadline

Questions

Do I need records for general use products, or only restricted use?

Both. Oklahoma’s rule requires commercial and noncommercial applicators to keep accurate records of every pesticide they apply, general use as well as restricted use; only private applicators record restricted use alone.

Whose certification number goes on the record?

The certified applicator who made or supervised the application: their name, certification number and certification expiration date, plus the name of any noncertified applicator working under direct supervision. Oklahoma licenses the business and certifies the person, so this is not the business license number.

Does Oklahoma require weather or a deadline for the record?

No. The record rule lists no weather item and sets no deadline by which the record must be written.

Can a service technician spray a lawn without a certified applicator there?

Yes, a service technician may make the application on site, since a service technician or a certified applicator must be present at each application. A certified applicator must be on site to supervise anyone who is not a service technician, and whenever the label requires it.

Do I need lawn signs or to notify customers in Oklahoma?

Oklahoma’s pesticide rules have no customer notice, neighbor notice or lawn sign rule for turf and ornamental applications, and cities and counties may not adopt notification or posting rules stricter than the Board’s. Label-required posting still applies.

Does Oklahoma have a turf fertilizer law for lawn care companies?

The Fertilizer Act and its rules set no applicator license, per-application record, nitrogen or phosphorus limit, blackout dates or application setbacks for turf. Fertilizer dealers need a license for each business location at $50 a year, and a company that mixes custom blends must be licensed as a custom blender.
