In France, a technical study on farm chemicals has suddenly become a political flashpoint, splitting scientists and lawmakers.
What began as a routine expert assessment for the French agriculture ministry has turned into a fierce argument over pesticides, scientific independence and the future of EU green rules.
A technical report that became political dynamite
In autumn 2025, France’s National Research Institute for Agriculture, Food and the Environment (Inrae) handed the agriculture ministry a dense report on one very specific question: which alternatives could replace neonicotinoid insecticides in several key crops?
The mandate covered six sectors under heavy pest pressure: sugar beet, hazelnut, cherry, apple, fig and turnip. Neonicotinoids, long used to protect seeds and young plants from aphids and other insects, have been highly restricted in the EU because of their risks to bees and other pollinators.
On paper, the report was meant to be a technical roadmap for farmers and policymakers. In reality, it landed in the middle of a heated political struggle around a proposed law led by conservative senator Laurent Duplomb, from Haute-Loire.
Duplomb is pushing a new text, dubbed “Duplomb 2”, aimed at reauthorising two neonicotinoid-type substances in France: acetamiprid and flupyradifurone. His proposal surfaced just as a citizens’ petition against his first version of the bill was due to be debated in the National Assembly in February.
At stake is whether France sticks to a strict phase-out of bee-harming insecticides, or opens a door to their partial comeback.
Why Duplomb leans on the Inrae report
To defend his second bill, Duplomb points to the Inrae expertise as a form of scientific backing. His argument, according to people familiar with the parliamentary debates, is that the report highlights major “dead ends” for certain crops, where current tools do not sufficiently protect yields or quality.
In political speeches and hearings, he presents the document as proof that farmers are left with no viable options against pests without a temporary return of some neonicotinoid-style molecules. That narrative speaks directly to sugar beet growers and orchard owners who fear another round of devastating infestations.
The framing is simple and powerful: if science says there are technical deadlocks, then emergency authorisations or a special law look like common sense.

Inrae pushes back against ‘instrumentalisation’
Inside Inrae, that reading has sparked anger. Several researchers involved in the expertise say that the report has been cherry-picked and simplified to justify a pre-existing political agenda.
Scientists at Inrae insist their conclusions do not identify insurmountable “technical impasses” that would justify reintroducing banned pesticides.
Inrae’s leadership has publicly stressed that the document details a range of non-neonic options, from alternative chemical molecules to biological control and agronomic practices. According to people inside the institute, the overall message is that transition paths exist, even if they are not yet perfectly mature or cost-neutral for farmers.
Yet some passages of the report, including its phrasing around “temporary difficulties” and “risk of economic loss” for certain crops, have been seized upon in the political arena. That ambiguity is now at the centre of the controversy: did the wording unintentionally give ammunition to pro-pesticide lobbyists, or was the document simply being wrenched out of context?
A research body caught in a political storm
The row has spilled into internal debates at Inrae itself. Researchers are split between those who argue that scientists must stick strictly to data and uncertainty ranges, and those who believe they should speak more clearly about the political consequences of their work.
Some staff members worry that the institute is being pulled into a culture war over environmental regulation, not unlike the way climate scientists have been targeted in other countries.
Others say the case highlights a more mundane problem: expert reports written for ministries are often drafted in bureaucratic language that can be reinterpreted once they leave the scientific sphere and enter parliament.
The fight is not only about insects and crops, but about who gets to speak in the name of “science” when laws are written.
What are acetamiprid and flupyradifurone?
Both substances at the heart of the Duplomb law belong to families close to the neonicotinoids that have been phased out in Europe.
- Acetamiprid is part of the neonicotinoid group. It is less persistent and generally considered less toxic to bees than some older neonics like imidacloprid, but NGOs and some scientists argue that chronic exposure and cocktail effects are still worrying.
- Flupyradifurone is a newer compound, sometimes described as a “neonicotinoid cousin”. It targets the same receptors in insect nervous systems. Regulatory agencies have authorised it under strict conditions, but several studies point to sublethal effects on pollinators.
Supporters of Duplomb’s bill say these two molecules offer a compromise: strong pest control with manageable environmental risks. Environmental groups counter that re-opening the door for such products undermines the whole EU strategy to shift away from systemic insecticides.
Farmers caught between pests and politics
For growers, the debate feels less abstract. In recent years, sugar beet fields in France have been hit hard by virus yellows, spread by aphids. The end of neonicotinoid-treated seeds exposed crops to new waves of infestation, leading to yield losses and financial stress.
Fruit producers, especially in cherries and apples, face invasive insects and fluctuating market prices. Many say they have little room for experimentation when already squeezed by low farm-gate prices and imported competition.
Inrae’s report reportedly lists several categories of alternatives, each with limits and advantages.
| Type of solution | Examples | Main challenges |
|---|---|---|
| Chemical substitutes | Non-neonic insecticides, targeted sprays | Resistance risks, impact on beneficial insects, higher costs |
| Biological control | Predatory insects, parasitoid wasps | Need for training, variable field performance |
| Agronomic practices | Crop rotation, sowing dates, resistant varieties | Requires planning, may not fully control outbreaks |
| Mechanical/physical methods | Traps, nets, barrier films | Labour-intensive, investment costs |
For many farms, the viable path is not a single magic bullet but a mix of several tools, tailored to local conditions and pest pressure. That transition needs time, advice services, and often public funding.
Science, law and the grey zones in between
The Duplomb episode shows how fragile the line can be between scientific advice and political use of that advice. When an institute like Inrae submits an expert report, it rarely tells lawmakers what exact article of a bill to write or delete. Instead, it sets out scenarios, trade-offs and uncertainties.
Parliament then chooses one storyline. In this case, Duplomb and his allies have elevated the most alarming scenario for farmers, while others in government and civil society highlight the pathways away from neonicotinoids described in the same report.
Inside the research community, there is growing discussion about how to produce documents that are harder to misinterpret. Some suggest clearer executive summaries that state, in plain language, what the report does not support, not just what it describes.
Key terms behind the controversy
For readers less familiar with pesticide politics, a few concepts help make sense of the clashes.
- Neonicotinoids (“neonics”): A family of insecticides that act on the nervous system of insects. Highly effective at low doses, but strongly linked to bee decline when used widely.
- Substitutes or alternatives: These can be other chemicals, but also biological methods, changes in cropping systems or digital monitoring tools.
- Technical impasse: A situation where, based on current knowledge and tools, no combination of methods can guarantee acceptable control of a given pest without banned products.
The controversy around the Inrae report largely revolves around whether such “impasses” really exist for the six studied sectors, or whether the difficulties are transitional and manageable.
What this could mean for future EU green rules
The French debate is being watched closely in Brussels and other EU capitals. If one of the bloc’s largest farming nations carves legal exceptions for acetamiprid and flupyradifurone, others might follow, weakening the overall push to reduce synthetic pesticide use.
It could also influence how future EU regulations treat scientific advice. Lawmakers may demand clearer opinions from agencies and research bodies, stating under which conditions emergency derogations could be justified, and when they should be ruled out.
For farmers and environmental campaigners alike, the trajectory is far from settled. A likely scenario over the next few years is a patchwork of regional rules, pilot projects on biological control, and recurring attempts in parliament to reopen debates on specific molecules as new pest crises arise.
That kind of stop-start regulatory landscape can itself create risks. Companies may hesitate to invest in safer alternatives if they expect old chemicals to keep returning through political pressure. At the same time, a rigid ban without support measures may erode trust in public policy among farmers who feel cornered.
How France handles the Duplomb law and the disputed Inrae report will signal which of these paths it intends to follow, and how much weight scientific nuance will carry when the next crop crisis hits.
