Which Certiphyto Category to Choose: Decision-Maker, Operator, Sales or Advice

The Certiphyto is not a single certificate: it is a family of five, spread across three activities and issued for two distinct sectors. Choosing the wrong combination means attending a whole session for nothing. Here is how to settle it in three questions.

Three activities, five categories

The French rural code organises the scheme around three activities.

Professional use of plant protection products splits into three categories:

• Decision-maker in a non-approved company (DENSA) — the person who selects products, decides on doses and timing, buys, and organises product use for their own account. This is the farm-manager category, numerically the largest.
• Decision-maker in an approved company (DESA) — the same decision-making role, but within a business that applies products at third-party sites, as a service: agricultural contractors, applicators, landscaping firms working for clients.
• Operator — the person who applies products following instructions: driving the sprayer, preparing the mix, cleaning equipment. They carry out a strategy they did not define.

Sale and marketing forms the second activity. The certificate distinguishes selling products intended for professional users from selling products intended for non-professional users.

Advice on use forms the third: it covers people who recommend or prescribe product use in a professional setting.

The three-question method

Question 1 — Do I decide, or do I carry out?

This is the most structural split, and the one most often misjudged.

You are a decision-maker if you choose the product, settle the dose, decide when to treat, or buy the products. You are an operator if you apply what you are asked to apply.

The practical test: if you left for three weeks, would someone have to decide in your place? If so, you are a decision-maker.

Beware a frequent confusion: an experienced employee who “knows what needs doing” is not thereby a decision-maker in the scheme’s sense. What counts is formal responsibility for the choice, not technical skill.

Question 2 — Do I work at third-party sites?

This question only arises for decision-makers, and it separates DENSA from DESA.

If your business applies plant protection products on behalf of clients, it falls under the company approval provided for in the rural code, and its decision-makers need the DESA category. If you treat only your own land, it is DENSA.

Do not confuse the Certiphyto with the approval. Approval is granted to an organisation and rests notably on third-party certification; the Certiphyto certifies a person. An approved company employs certified people: the two schemes stack, they do not substitute for one another.

Question 3 — Farming or JEVI?

The certificate is issued for a sector, and that mention appears on the document.

The agricultural sector covers crop production and livestock: viticulture, arable, market gardening, orchards. The JEVI sector — gardens, planted areas and infrastructure — covers green spaces, sports grounds, cemeteries, roadsides, golf courses, and railway and motorway land.

A landscaper, a local-authority agent or a golf-course manager falls under JEVI. Course content genuinely differs there, not least because the range of permitted uses is far narrower. We devote a whole article to it: the JEVI Certiphyto.

Four concrete situations

Situation	Activity	Category	Sector
Arable farmer deciding and applying their own treatments	Use	DENSA	Agriculture
Vineyard employee driving the sprayer	Use	Operator	Agriculture
Contractor treating at clients’ sites	Use	DESA	Agriculture or JEVI, depending on the work
Salesperson in an agricultural supply store	Sale, marketing	Sales	Depends on the products distributed

The case of a collaborating spouse or partner who takes part in decisions deserves careful thought: if they genuinely arbitrate treatment choices, the decision-maker category applies. The case of a cooperative technician who both advises and applies calls for stacking: two certificates, two routes.

Why “operator” is not a lesser category

A persistent misconception holds that the operator certificate is a lightweight version of the decision-maker one, and that a decision-maker “covers” their operators. Both points are wrong: each person concerned must hold their own certificate, and the operator is not a junior decision-maker — they are the most directly exposed.

Research bears this out. The PESTEXPO study, which measured actual contamination of operators during vineyard treatments, found that the spraying phase accounts for around half of dermal contamination, with mixing and equipment cleaning sharing the other half (Baldi, Lebailly, Rondeau et al., Journal of Exposure Science & Environmental Epidemiology, 2012). In other words, the gestures readily treated as secondary — filling, rinsing, cleaning — weigh heavily in exposure.

This is not a theoretical concern. The AGRICAN cohort, which follows more than 180,000 members of France’s agricultural social insurance scheme, observed increased incidence of certain cancers in the farming population — prostate, non-Hodgkin lymphoma, multiple myeloma, melanoma — even though overall incidence was not higher than in the general population (Lemarchand et al., Cancer Epidemiology, 2017 — see the study). The content of the operator session is justified by that evidence, not by administrative formality.

What if I chose the wrong category?

The certificate states the activity, the category and the sector. If it does not match your actual situation, it does not cover you: you must follow the route for the right category. Hence the importance of settling the question before enrolling, with the provider, rather than after the session.

For borderline cases — multiple activities, employer groupings, delegated management — the DRAAF in your region is the authoritative contact. A phone call before enrolling costs less than a repeated session.

Take action

Work through the three questions in order: do I decide or carry out, do I work at third-party sites, farming or JEVI. Write down the resulting combination, have it confirmed by the authorised provider you have chosen, then follow the application route detailed in our practical guide. The Certiphyto profile sets out every category and the texts that define them.
