Senator Laurent Duplomb Revisits Bill After Constitutional Council Rejection

When we look at the legislative battles unfolding in France over the “Loi Duplomb,” it might seem like a distant European squabble over pesticide regulations. But for those of us here in the Central Valley of California—the agricultural heartland of the United States—the stakes are hauntingly familiar. Whether it is a debate in Paris or a policy shift in Sacramento, the tension remains the same: the desperate struggle to balance the immediate survival of crop yields against the long-term health of our pollinators and the environment. The recent push for “Duplomb 2” isn’t just a French legal maneuver; it is a mirror reflecting the global volatility of agricultural chemistry.

The Legal Tug-of-War Over Neonicotinoids

To understand the current friction, we have to look at the trajectory of the original Loi Duplomb. Adopted in early July 2025, the law aimed to lift constraints on the farming profession. However, it hit a massive wall on August 7, 2025, when the Conseil constitutionnel—France’s highest constitutional authority—partially censored the act. The point of contention was Article 2, which sought to allow the derogatory reintroduction of certain phytopharmaceutical products, specifically neonicotinoids like acetamipride.

The Conseil constitutionnel didn’t just strike it down on a whim. They based their decision on the Charte de l’environnement, which is integrated into the French Constitution’s preamble. The “Sages,” as the council members are known, determined that the conditions for reintroducing these pesticides were not strict enough to justify the risks to public health and the environment. Acetamipride had been banned in France since September 1, 2018, due to its deleterious impact on pollinating insects, though it remained authorized in other parts of Europe until 2033. This creates a fragmented regulatory landscape where farmers in one country feel they are fighting with one hand tied behind their backs while their neighbors across the border have access to more potent tools.

The Emergence of “Duplomb 2”

Senator Laurent Duplomb, a member of Les Républicains and a farmer himself, isn’t backing down. On April 2, 2026, Duplomb and Senate President Gérard Larcher called for the insertion of a new text, dubbed “Duplomb 2,” into a future agricultural emergency law. This new proposal, first filed on January 30, is backed by five senators from various political groups, ranging from the Radicals to Les Républicains.

The goal of “Duplomb 2” is specific: to allow derogations for two substances—acetamipride and flupyradifurone. Both share the same mode of action. The focus is narrowed to four critical sectors: sugar beets, hazelnuts, apples, and cherries. These crops are currently facing pests that farmers argue are uncontrollable without these specific chemicals. To avoid another constitutional shutdown, the authors sought an opinion from the Conseil d’Etat on March 26. The state council suggested that the “general interest objective” could potentially justify the impact on health and prevention rights, provided the legislative framework is sufficiently tight.

Global Implications for the Central Valley

While Here’s a French legislative battle, the ripple effects are felt by any region reliant on industrial-scale monoculture. In the Central Valley, we deal with similar pressures. When a major European power fluctuates on its ban of neonicotinoids, it signals a shift in the global consensus on sustainable farming practices. If France moves back toward chemical dependency to save its “ferme France,” it provides a political blueprint for other nations to roll back environmental protections in the name of economic urgency.

The debate centers on the “duty of prevention.” In the U.S., we see this play out in the tension between the Environmental Protection Agency (EPA) and agricultural lobbyists. The French experience shows that even when a law is passed, the judiciary—via the Conseil constitutionnel—can act as a final bulkhead against policies that threaten the ecological foundation of the land. For those of us managing orchards and vineyards near Fresno or Bakersfield, the lesson is clear: the regulatory environment for pesticides is no longer just about efficacy; it is about constitutional viability.

The Economic Pressure of “Emergency” Legislation

The term “loi d’urgence agricole” (agricultural emergency law) is telling. It frames the use of banned pesticides not as a preference, but as a necessity for survival. This “emergency” framing is often used to bypass the slower, more rigorous scientific review processes. By targeting specific crops like cherries and apples, the “Duplomb 2” proposal attempts to carve out a “surgical” exception. However, as the previous censorship proved, “surgical” exceptions often leak into broader environmental degradation.

If you are navigating these shifting tides in your own operations, it is crucial to stay informed on environmental compliance standards to ensure that a sudden shift in chemical legality doesn’t leave your harvest at risk or your land contaminated.

Navigating Local Agricultural Transitions

Given my background in analyzing the intersection of policy and land management, I know that when global trends shift toward “emergency” chemical use or strict bans, local producers in the Central Valley need more than just news—they need a strategic pivot. If the volatility of pesticide legality is impacting your operations here in California, you shouldn’t be guessing your next move. You need a specialized team to audit your soil and your legal standing.

Depending on your specific needs, here are the three types of local professionals you should be consulting right now:

Integrated Pest Management (IPM) Consultants

Look for specialists who don’t just suggest alternative chemicals, but who can design biological control systems. The ideal consultant should have a proven track record of reducing neonicotinoid reliance without sacrificing yield in high-value crops like almonds or grapes. They should be able to provide data-backed alternatives to the “emergency” chemicals discussed in the Duplomb legislation.

Agricultural Environmental Law Specialists

You need a lawyer who specializes in the intersection of state mandates and federal EPA guidelines. Ensure they have experience with “derogatory” permits and a deep understanding of the California Environmental Quality Act (CEQA). They should be able to help you navigate the legality of your chemical applications to avoid the kind of constitutional challenges seen in France.

Soil Health & Regenerative Agronomists

Instead of treating the symptom (the pest), these professionals treat the system. Look for agronomists who specialize in soil microbiome restoration. The goal is to build crop resilience so that “emergency” pesticides become unnecessary. Prioritize those who provide quantitative soil carbon and biodiversity metrics rather than just qualitative advice.
