Reviewed: 2026-10-23

Ohio commercial application records use different schemas for the categories described in OAC 901:5-11-10(A)(1) and for applications covered by (A)(2). The latter field-work schema includes weather, equipment, product amount, diluted volume where applicable, and application start and completion or cessation time. Record the required information in English on the application date, then handle the separate business and customer copies. [^1]

## Select the correct commercial schema

Paragraph (A)(1) concerns the specified pesticide-use categories and structural applications. Paragraph (A)(2) addresses applications not covered by (A)(1). A commercial field-spray worksheet should therefore be compared with the (A)(2) contents rather than a structural-treatment record that uses a different list. [^1]

| Group | Commercial (A)(2) information |
| --- | --- |
| People | Responsible commercial applicator and supervised trained servicepersons |
| Customer | Name and address of the person contracting for service |
| Event | Application date and start/end or daily cessation time |
| Treatment place | Area type and size; location or field ID when different from the customer address |
| Products | Brand and EPA registration number; total amount of each product |
| Dilution | Total use-dilution volume if the pesticide is diluted |
| Equipment and weather | Equipment type, wind direction and velocity, air temperature |

The table summarizes the application schema in the Ohio rule. Keep the field meanings explicit when designing an electronic record or reviewing a contractor's exported document. A broad heading such as application details should not conceal separate product, dilution, and treatment-area quantities. [^1]

## Identify the people making and supervising the application

The (A)(2) record names the responsible commercial applicator and the trained servicepersons applying under that applicator's direct supervision. Ohio's definitions explain the commercial supervision arrangement in relation to instructions and control, training, and product labeling. Preserve each person's role rather than listing only the business name. [^1][^2]

Build a personnel key with names as used on the application records and the corresponding training or credential references. When a crew changes during the season, review repeated names before copying a prior entry. Keep the responsible commercial applicator distinct from the person who typed the record or received the invoice.

The rule separately requires businesses to retain written verification of a trained serviceperson's required manual reading or equivalent training for three years after that employee's termination. That employment-based retention clock is different from the application-record period. Preserve the training file under the person's identity and the termination reference used for its archive. [^1]

## Product amount and diluted volume are different fields

Paragraph (A)(2) lists the total amount of each pesticide product used and, if diluted, the total volume of use dilution applied. Keep those values separate. The product identity includes the trade or brand name and EPA registration number, allowing the quantity to remain connected to the correct material. [^1]

For an application using several products, preserve each product's amount rather than only a name for the mixture. Read the source note for the unit and distinguish a container quantity from a mixture volume. If a worksheet offers only one total box, compare it with the two quantities in the rule before treating the entry as complete.

As an editorial review exercise, give the transcriber a source note and ask them to identify which number describes formulated product, which describes the use dilution, and which describes treated area. Resolve any ambiguous number with the applicator. Preserve the written clarification and the original note with the completed record.

## Locate the treatment independently of the customer address

The rule identifies the treatment area's location or field number when different from the contracting person's address, along with the type and size of area treated. A billing address should therefore remain distinguishable from the actual field or block description. Prepare a location dictionary connecting the working field name to its map reference. [^1]

For a contractor moving among several farms, preserve the customer name and treatment site as separate searchable fields. If several blocks share a property address, retain the block identity used in the treatment note. Keep renamed fields connected to the naming key from the application year so a later reviewer can interpret the older record.

## Record daily start, completion, or cessation

The schema asks for the time actual application starts and when it finishes or, if unfinished, when operations cease for the day. Preserve a cessation time as such; it describes an unfinished operation rather than asserting the entire treatment was completed. Keep the application date connected to the day's timing. [^1]

Create a handover routine in which the applicator checks the time notation before the record is finalized. Distinguish preparation or travel time from actual application start in your internal field dictionary. If the work continues on a later date, preserve enough context in the supporting notes to explain the relationship between the entries without silently replacing the earlier day's values.

## Weather and equipment belong to the application

The (A)(2) field list includes wind direction, wind velocity, air temperature, and equipment type. Keep the weather information linked to the recorded application rather than a general planning forecast. Write the measurement units and explain any abbreviations used by the field team. [^1]

Review a completed row with the actual applicator: identify the direction notation, velocity unit, temperature unit, and equipment description. If a familiar equipment nickname would be unclear to another reader, preserve its correspondence to the equipment used. These are documentation steps and do not establish a product's allowable weather conditions or recommend a treatment.

## Business copy within ten days

Paragraph (A)(5) requires the commercial applicator to submit a copy of the specified application records within ten days after completion to the registered business location from which the work was conducted, or to the employer when the employer is not a pesticide business. Preserve the destination with the job reference. [^1]

This handover is separate from recording on application day. Keep a dispatch index identifying the completed record, its destination, and the date sent. If a field note is later clarified, label the reviewed version and identify which copy the receiving office should use. Preserve the source of the clarification rather than leaving two unnamed versions in the archive.

## Customer copies for the specified agricultural categories

Paragraph (A)(6) identifies particular agricultural pesticide-use categories for customer copies. It requires a copy on request or, without a request, within 30 days after application, unless the contracting person supplied a signed agreement allowing the business to retain the record. Keep the relevant agreement with the customer's file when using that stated condition. [^1]

Prepare customer and business delivery references separately. A record sent to the registered office does not itself show which information reached the person contracting for the service. On the farm side, preserve the received application copy with the field and product references so it can be reconciled with the work performed.

## Three-year application archive

The rule requires the receiving employer or pesticide business to retain application or inspection records for three years from the application or inspection date and make them available to the director. Preserve the appropriate registered-location reference and retain a readable record with the necessary location and quantity keys. [^1]

To test the archive, ask a colleague to retrieve a field treatment with more than one product and distinguish product amounts from use-dilution volume. Have them identify the daily timing, weather, actual people, business-copy destination, and customer-copy reference. Record specific corrections with their documentary basis. This proposed review concentrates on the distinct Ohio commercial field schema and its handover duties.

## Compare the field schema with the structural schema

The (A)(1) schema expressly records pests to be controlled, treatment locations and methods for each pesticide, and concentration or dilution with total volume. The (A)(2) schema instead explicitly separates total amount of each product from total use-dilution volume and includes treatment-area type/size, equipment, and weather. Use those differences as a concrete acceptance test when adapting a structural-service ticket for field applications. [^1]

The same rule contains additional records for termite-related structural work, including the stated footprint drawing and bait or monitoring-device information. Preserve those as a distinct service category when the same business performs several types of work. A termite-specific diagram should not become the unexplained location field on an agricultural spray worksheet. [^1]

## Separate application archives from employment evidence

Three dates can have different meanings in a commercial file: the application date, completion-based dispatch date, and an employee's termination date. The rule assigns the business-copy period to completion, the application archive to application or inspection, and the training-verification archive to termination. Put the event name beside the date in the retention index so a single timestamp does not stand in for all three. [^1]

For a staffing handover, prepare a personnel register with full names, supervised roles, training-document references, and the job records those references support. Retain a readable directory for former employees where needed to interpret historical applications. Keep the written training verification identifiable independently of a credential image or an unsigned attendance note.

Ask the receiving administrator to find an older field application and explain the people listed, source measurements, daily timing, customer reference, and business destination. Then have them locate the associated training evidence using the named person rather than the job's filename. Record a broken reference as a specific handover issue and resolve it before closing the employment file. These are proposed retrieval tasks for the rule's separate record responsibilities.

During dispatch reconciliation, verify that forwarded attachments preserve page numbering, handwritten annotations, signature references, and the destination office. Identify superseded revisions explicitly in the correspondence so the receiving administrator can distinguish the reviewed copy from a draft.

### What must Ohio commercial pesticide application records include?

The (A)(2) schema includes responsible and actual people, customer, date, area type/size and location, product/EPA number, product amount, applicable dilution volume, equipment, times, and weather. [^1]

### When must Ohio commercial pesticide records be completed?

The required information is recorded in English on application day. The business-copy deadline is a separate ten-day-after-completion duty. [^1]

### How long must Ohio commercial pesticide application records be kept?

The receiving employer or business keeps the specified application records for three years from application. [^1]

### Can an Ohio pesticide application record show a daily stop time?

Yes. The rule records completion time or, when the operation remains unfinished, the time operations ceased for the day. [^1]

### When does an Ohio agricultural customer receive the pesticide record?

For the specified agricultural categories, on request or within 30 days absent a request, subject to the stated signed-retention-agreement condition. [^1]
