Drone spraying and seeding: price per hectare and legal framework
For years the answer was simple: drone spraying was banned in France, full stop. Law 2025-365 of 23 April 2025 changed that by opening a supervised derogation, detailed by its implementing texts published in spring 2026. For farmers, two questions now matter: is my plot eligible, and how much does it cost? Here are the observed per-hectare rates, the exact conditions of the derogation and the buyer-side steps — without confusing spraying, seeding and mapping, three services under very different regimes.
What law 2025-365 actually changes
The principle set by the French rural code still stands: aerial spraying of plant-protection products is banned in France. What law 2025-365 of 23 April 2025 introduces is a targeted derogation for remotely piloted aircraft, driven by an occupational-safety finding: on steeply sloped plots, spraying by hand or with a tracked tractor exposes workers to serious accidents (rollovers, falls) and higher product exposure. The drone removes those risks while reducing drift by flying a few metres above the canopy.
The implementing texts published in spring 2026 precisely define the derogation's scope. It covers plots with a slope of 20% or more — hillside vineyards first and foremost —, banana plantations (a major issue in the French Antilles) and rootstock mother vines. And only with biocontrol products, products authorised in organic farming or low-risk products. Everything else — a conventional treatment on flat land, for instance — remains prohibited. An operator offering that kind of job would expose you, as well as themselves, to penalties.
Seeding, biocontrol drops, fertiliser: what was never banned
A second essential clarification, because years of headlines have kept the confusion alive: the historical ban only covered the spraying of plant-protection products. Drone seeding — cover crops into standing maize before harvest, mixed forage, grassland — was never caught by that ban: it is seed spreading, not pesticide application. The same goes for trichogramma releases (capsules of beneficial insects against corn borer), which became the biggest market for agricultural drones in France, and for spreading biocontrol slug pellets or granular fertiliser on inaccessible areas.
Cover-crop seeding actually offers the best economic case: sowing into standing maize in late July or August gives the cover crop a six-week head start over post-harvest sowing, with no tractor pass and no soil compaction. The machinery co-ops and contractors that adopted it bill per hectare, covering 20 to 40 ha per day. For mapping and diagnostics (NDVI, plant counts, variable-rate maps), which fall under yet another, much simpler regime — aerial imaging —, see our guide to drones in precision agriculture.
Per-hectare rates observed in 2026
Ranges observed among specialist operators and equipped agricultural contractors, excluding inputs (products and seed remain at the farmer's expense):
| Service | Observed rate (excl. VAT) |
|---|---|
| Derogated spraying (vineyard slope ≥ 20%, biocontrol) | €20 to €40/ha per pass |
| Broadcast cover-crop seeding | €40 to €60/ha |
| Trichogramma release (maize) | €15 to €30/ha, often bundled with supply |
| Prior NDVI mapping | €75 to €250/ha depending on sensor and area |
| Minimum call-out charge (travel included) | €300 to €500 |
Two reading rules. First, the minimum charge: below 8 to 10 ha it is the one that applies, hence the value of pooling jobs between neighbours or through the co-op — now common practice in hillside areas. Second, the slope: paradoxically, the drone is most competitive on the steepest plots, where the service is most expensive to deliver, because the alternative (tracked machine, backpack spraying) costs two to three times more and puts people at risk.
The farmer's side of the paperwork: who does what
Good news for the buyer: most of the administrative burden falls on the operator. They must be a registered UAS operator (operator number affixed to the drone, aerial third-party liability insurance mandatory under Regulation (EC) No 785/2004), hold the plant-protection application licence for the spraying part, and operate within the derogation with suitable equipment. Check these three points before signing, exactly as you would check a conventional contractor's accreditation.
On the farm side, your obligations remain those of any treatment: hold the Certiphyto certificate to decide on the treatment, use only products authorised for the intended use (and falling within the biocontrol/organic/low-risk scope for drone application), respect pre-harvest intervals and record the operation in the spray register. Also document the plot's eligibility: the 20% slope is assessed on the treated plot, and a serious operator will ask you to substantiate it (topographic survey, land-parcel register, or measurement on a digital terrain model). Finally, plan ahead: between the quote request, the eligibility check and the weather window (low wind required to limit drift), allow two to four weeks. The agricultural drone page presents the full range of services and lets you request a combined mapping + application quote.
Frequently asked questions
Is drone spraying legal in France in 2026?
Pesticide spraying remains banned in principle, but law 2025-365 opens a derogation: plots with slopes of 20% or more, banana plantations and rootstock mother vines, with biocontrol, organic-approved or low-risk products only. Seeding and beneficial-insect releases have always been free of that ban.
How much does drone application cost per hectare?
€20 to €40/ha per pass for derogated spraying, €40 to €60/ha for cover-crop seeding, with a minimum call-out charge of €300 to €500.
Is my flat plot eligible for drone spraying?
No, unless it falls under the other derogation cases (banana plantation, mother vines). Outside the derogation, only non-pesticide services (seeding, trichogramma, granular fertiliser, mapping) are possible.
Does the operator need specific accreditations?
Yes: UAS operator registration, aerial liability insurance (Regulation EC 785/2004) and a pesticide-application licence for spraying. Ask for the documents with the quote.
