Read HSE's official record-keeping guidance for Great Britain. For Northern Ireland, read DAERA's detailed requirements. Registering the business is a separate task from recording each pesticide application.
Start with the application, not the registration form
A treatment diary describes actual product use. A registration document identifies the business to the authority. Keep them in separate sections of your administrative file, connected by the business identity where useful. The professional PPP registration guide covers the registration task.
In Northern Ireland, the core professional-user application information is the product name, time and dose of application, treated area and crop. Records must be retained for at least three years, and Great Britain has the same three-year category for professional users.
Set up the diary so those facts remain connected to the same application. A product invoice records a purchase, while a recommendation records an intention. Describe what happened in a completed-treatment entry, and keep the invoice and the recommendation as supporting papers.
What the core fields mean in practice
| Core information described by DAERA | Practical way to make the entry readable |
|---|---|
| Product name | Retain the actual product identity used |
| Time of application | Identify the treatment's date and timing clearly |
| Dose | Preserve the value with its unit |
| Area | Identify the actual area treated |
| Crop | Name the crop associated with the application |
The right column is a recording checklist, not a statutory form. A table helps only when another reader can understand the units and connect the values to the actual operation.
For Scotland, Annex F supplies an official treatment-record model with operational fields. Keep the original document's scope attached to it rather than presenting every field on an example form as a universal legal requirement throughout the UK.
In Northern Ireland, paper records remain acceptable through 31 December 2026; mandatory machine-readable records apply to uses from 1 January 2027. Existing record-keeping duties continue during 2026.
Northern Ireland: distinguish content from electronic transfer
Northern Ireland records also carry the MAPP product authorisation number and the EPPO crop or land-use code. BBCH growth stage is included where the product label restricts use to a particular growth stage.
Mandatory electronic transfer in Northern Ireland is postponed to 1 January 2027. The 2026 approach to non-compliance with the new content requirements does not remove existing record duties. A transition in enforcement of new fields is not a reason to omit the existing application history.
For NI uses from 1 January 2027, paper entries must be converted to the prescribed electronic format. Article 3 sets a default limit of 30 days after use, allowing shorter national periods; the longer annual period is permitted only for uses before 1 January 2030, with records available electronically before 31 January of the following year. For example, a 2027 use can be recorded electronically by 31 January 2028. Recording the application itself remains required without undue delay.
For the detailed timetable and supporting material, continue with digital spray records. Do not apply the NI timetable to Great Britain solely because the farm or contractor uses the same software in both locations.
Which electronic format is useful in NI?
In Northern Ireland, machine-readable records are information that can be extracted, searched, analysed and transferred without manual re-entry. CSV, XLSX, XML and JSON are examples. A PDF or scanned image does not meet that machine-readable-original description.
Retain the structured file, its field names and units. If you send a reading copy to a customer, name it as a report and keep the original distinguishable. When changing software, open the export and check a treatment against the source entry rather than judging only its page layout.
DAERA supplies an agricultural and horticultural workbook with supporting guidance. Use the DAERA template guide to reach the current official download, understand its field structure and identify the relevant crop-code material.
Contractor originals and customer copies
For NI uses from 1 January 2027, DAERA places responsibility for retaining the compliant machine-readable record with the contractor who performs the application. It allows the contracting business to keep a reference copy such as a PDF while the contractor maintains the required original. It also addresses providing the machine-readable record when requested.
Keep your spray records in one place. Free to start.
Agree the handover before the spraying starts. Name the location, operator and job reference consistently so the customer can connect the returned record to the work ordered. Check that the file describes completed work and that a cancelled or partial job has not been reported as a full application.
For Great Britain and for the practical exchange of records, use the contract sprayer guide. Do not transfer every NI-specific format or handover provision to a GB job without identifying the applicable basis.
Retention and retrieval are different checks
Keep the applicable minimum retention period in the archive plan, then test whether a record can actually be found and understood. A file kept in an account nobody can open, or in an unreadable format, cannot be retrieved, even if its filename survives a system change.
Professional-user records are kept for three years; the five-year category applies to producers, suppliers, distributors, importers and exporters. Do not assign that other-business category to every farmer simply because both periods appear in the same guidance.
Use business, season, field and job references to locate treatments. Keep any original supporting document connected to the entry. When a correction is necessary, preserve the reason and version so that the customer and operator can recognise which information changed.
Assurance and operational records can contain more detail
A farm's assurance scheme, customer arrangement or operational form can ask for information beyond the core application fields. Preserve the source and purpose of each requirement. A more detailed record can be useful without every column becoming a universal statutory obligation.
For harvest-related information and assurance records, use the harvest and access guide and Red Tractor records guide. For a printable working layout, use the spray record form.
Pesticide inspection: evidence beyond the treatment entry
HSE pesticide enforcement officers can inspect packaging, labels and user certification in Great Britain. They may also ask to see the records the law requires and how they are kept. The visit guide covers England, Scotland and Wales, and the officer needs to speak to staff who know enough to answer questions about the business's pesticide activities.
In Wales, field checks also cover whether personal protective equipment is available.
Northern Ireland has its own DAERA guidance on professional-user pesticide records. Keep it apart from the GB officers' visit guide when you decide which recording requirements apply.
Review an entry before filing it
Read the product identity, time, dose, area and crop together. Resolve an ambiguous unit with the person who recorded the operation. Compare an imported entry with its original and keep the original source identifiable. For NI, include the required detailed fields and preserve the structured version as described above.
Choose a past application and ask a colleague to retrieve it from the archive. Note which names, references or file locations caused confusion, then improve the index. This is an editorial filing exercise, not an additional inspection deadline.
The authority's official guidance defines the relevant duties; a journal entry does not itself register the business or submit records to a government portal.
Keep the source of a requirement beside your checklist
For every column in a business checklist, identify whether its basis is the statutory application record, a sector scheme, a customer request or an internal operating practice. Retain the source document and review date for the first two categories. This prevents a useful additional observation from being mislabelled as a universal legal obligation.
When the business operates in several territories, preserve the treatment location in the archive index. A software account's language or the owner's postal address does not describe where a particular application occurred. Use the actual operation to choose the applicable guidance, then keep that decision understandable for the next record keeper.
For an official request, retain its wording and identify the record set it concerns. Assemble the actual entries and supporting references rather than generating a plausible-looking reconstruction from purchases alone. Ask the original operator to resolve an unclear field and preserve any correction as a correction.
Use a source-led field dictionary
For each exported column, explain its meaning and unit in an accompanying dictionary: product identity, timing, treated extent, crop, quantity and any jurisdiction-specific code. Preserve distinctions between missing information, a genuine zero and a field that does not apply. Resolve those meanings before transferring historical entries; a successful file import alone does not establish accurate interpretation.
For the agricultural and horticultural DAERA workbook, the guide’s mandatory black-headed columns cover operator, application date and start/finish times; location, crop or land use and EPPO; treatment type, product name and MAPP; conditional BBCH, treated area or amount; application method, dose, water volume and any buffer zone applied.
