What 43,591 authorisations look like when you read the registers

Plant protection registers are the most consulted agricultural data in Europe and among the most misread. AgricultureID has ingested 43,591 authorisation records from official national registers, and what follows is less about the records than about the shape of the thing they came from.

The unit is smaller than people expect

A register entry is not "product X is approved". It is: this specific formulated product, from this authorisation holder, in this country, may be used on this list of crops, against this list of targets, at up to this rate, this many times, with these intervals and these conditions, from this date, under this authorisation number.

Every clause in that sentence is load-bearing. A summary that keeps the product name and the word "authorised" and drops the rest is not a shorter true statement; it is a different statement, and one that can lead directly to an illegal application.

Approval and authorisation are different layers

At Union level, active substances are approved under Regulation (EC) No 1107/2009. Nationally, products containing them are authorised. Article 28(1) of the regulation says a product shall not be placed on the market or used unless it has been authorised in the member state concerned.

So a substance can be approved across the Union while a product containing it is authorised in six member states, refused in two, and never applied for in the rest. "Approved in the EU" is a statement about the middle layer only.

Withdrawn does not mean gone

When an authorisation is withdrawn, the decision usually carries a grace period: a final date for sale and distribution, and a later final date for disposal, storage and use. Between those dates a product is withdrawn and legally usable.

A register that shows only a status flag flattens three distinct states — current, in grace period, expired — into two. AgricultureID records the dates the register publishes rather than a derived flag, because the derived flag is where the information goes missing.

The registers do not agree on how to say things

They publish in their own languages, with their own identifier schemes, their own crop nomenclature and their own formulation type codes. None of it normalises cleanly, and the places where normalisation is almost possible are the dangerous ones — a crop name that maps to a corpus entity in nine countries and means something slightly wider in the tenth.

Where a mapping is not certain, AgricultureID keeps the register's own words. That makes some pages less tidy and keeps them answerable to the source.

What we do not publish

We do not publish a shortlist of products for a crop and a pest. The register holds the conditions that decide whether a given use is lawful, those conditions are specific to a place, and a shortlist that omitted them would be actively harmful while looking like exactly the thing a user came for.

What the platform publishes is which register is authoritative for a country, what it contains, when a record was read, and a link to the record. The register is the answer. Our job is to be a reliable index of where the answer lives — and to be honest that an index is not the thing indexed.
