2.4 Record-Keeping Requirements
Key Takeaways
- Commercial applicators must retain application records for three years from the date of application under Iowa Code §206.15 and IAC 21—45.26.
- Required records include applicator name and certification number, product trade name and EPA registration number, rate, amount, site, date, start/stop time, and wind conditions for outdoor applications.
- The USDA program that required certified private applicators to keep federal restricted-use pesticide records (7 CFR part 110) was rescinded effective July 11, 2025, so a private applicator's remaining record duties come from the product label and any state or program-specific rule.
- Records must be furnished to IDALS upon written request, and failure to maintain them is a violation independent of whether the application itself was correct.
- Where multiple licensees are involved in an application, each licensee must maintain a set of records, and supervision qualification records for noncertified applicators are kept two years under IAC 21—45.22(15).
The Legal Basis for Records
Iowa imposes record-keeping through two linked authorities:
- Iowa Code §206.15 — the statute requiring commercial applicators to keep records of pesticide applications for three years and to furnish copies to the Secretary upon written request.
- IAC 21—45.26 — the operative rule (renumbered effective January 1, 2026 under ARC 9145C) that lists the specific data fields each record must contain.
The rule implements Iowa Code §§206.11(3) and 206.15. When the exam asks which rule governs record-keeping, the 2026 answer is 21—45.26. Older materials that cite a pre-2026 rule number for record-keeping are stale.
Who Must Keep Records
Every commercial applicator must maintain office records of all application activities for each pesticide applied. Where an application involves more than one licensed commercial applicator, or is billed through a licensed pesticide dealer, each licensee must maintain a set of records. A noncommercial applicator applying on employer property and a public applicator applying in the course of official duties also have record duties under IDALS rules.
Private applicators used to have a parallel federal duty. USDA's Agricultural Marketing Service ran the Federal Pesticide Recordkeeping Program under 7 CFR part 110, which required a certified private applicator to record each restricted-use application within 14 days and keep the record two years. USDA rescinded 7 CFR part 110 effective July 11, 2025 as obsolete, and IAC 21—45.26 applies to commercial applicators and retail dealers, not private applicators. A private applicator's remaining record obligations therefore come from the product label — many RUP labels, including fumigant and auxin-herbicide labels, mandate their own application records — and from any WPS or program-specific requirement. Keeping full records anyway remains the practical standard, because records are the only defense in a drift or misuse complaint.
Required Data Fields (IAC 21—45.26)
Each commercial applicator record must include the following:
| Field | Requirement |
|---|---|
| Licensee | Name and license number of the licensee |
| Customer | Name and address of the landowner or customer |
| Site | Address of the place of application of the restricted-use pesticide |
| Date | Date of pesticide application |
| Product | Trade name and EPA registration number of the pesticide product used |
| Quantity and rate | Quantity of product used, concentration/rate of application, and size of the treatment area |
| Wind (outdoor) | Temperature and direction/estimated velocity of wind at time of outdoor application, if applicable |
| RUP use | Use of the restricted-use pesticide, including the crop, commodity, stored product, or site |
| Time | Time the application begins and ends |
| Applicator | Name and certification number of the certified applicator who made or supervised the application |
| Supervised noncertified | Name of any noncertified applicator who made the application under direct supervision, if applicable |
A memory aid: the record must answer who (licensee, applicator, supervised person), where (customer, site), what (product, EPA reg. number, quantity, rate, area), when (date, start/stop time), conditions (wind, temperature), and why (crop, commodity, or site).
Retention and Production
Records must be retained for three years from the date of application and produced to IDALS upon written request. Failure to maintain records is a stand-alone violation; an applicator can be penalized for missing records even if the underlying application was otherwise lawful and label-compliant.
Two shorter clocks sit alongside the three-year rule and are easy to mix up:
| Record | Who keeps it | Retention |
|---|---|---|
| Application records (IAC 21—45.26, Iowa Code §206.15) | Commercial applicators, retail dealers | 3 years from the application |
| Dealer records of RUP transactions with uncertified buyers (21—45.26(2)) | Retail dealers | 36 months from the transaction |
| Noncertified applicator qualification records (21—45.22(15)) | Supervising commercial applicators | 2 years from the RUP application |
| Continuing-instruction attendance lists (21—45.52(4)) | Course providers | 3 years from the end of the course year |
Scenario
A commercial applicator treats a soybean field on June 15 with an RUP insecticide. The record for that application must be created at the time of application (not reconstructed later from memory), must include the EPA registration number from the product label, the wind speed and direction at the time of the outdoor application, the start and stop times, and the applicator's certification number. The record must be retained until at least June 15 three years later and produced to IDALS if requested.
Private Applicator Federal Records
Private applicators apply RUPs on their own or their employer's agricultural land. Under 40 CFR 171, private applicators must keep records of each RUP application, including the product, EPA registration number, crop or site, rate, amount, date, and location. These federal records are separate from any state-specific private applicator record rule. The exam often treats "private applicator RUP records" as a federal-law topic, so watch for the 40 CFR 171 citation in the answer choices.
Format and Inspection Access
Iowa does not prescribe a single form, but records must be legible, organized, and retrievable. Paper logs, spreadsheets, and applicator software are all acceptable as long as every required field is captured. IDALS inspectors may request records during a routine inspection or a misuse investigation; the applicator must be able to produce them. "I will reconstruct them later" is not a defense.
Common Record-Keeping Violations
- Failing to record the EPA registration number (applicators often write only the trade name).
- Omitting wind data for outdoor applications.
- Recording the date but not the start and stop times.
- Reconstructing records after the fact when an inspector requests them, rather than maintaining them contemporaneously.
- Not retaining records for the full three-year period.
- Failing to record the name of a noncertified applicator who made the application under supervision.
A commercial applicator treats a client's lawn with an RUP herbicide and records the trade name, date, and rate, but omits the EPA registration number and the wind speed and direction. Under IAC 21—45.26, what is the status of this record?
