Farmer Thierry Breaks Pesticide Taboos and Faces Threats for Speaking Out

In the fertile plains of the Crau region, nestled between the Camargue and the Étang de Berre, organic farmer Thierry Gozzerino tends to his land with deep pride and unwavering commitment. His soil, rich and soft, yields impressive harvests—like sweet potatoes the size of rugby balls—reflecting years of dedication to regenerative farming. But behind this flourishing farm lies a troubling battle: Thierry has become a vocal critic of pesticide use, exposing practices that endanger both the environment and his livelihood, all while facing intimidation for speaking out.

Thierry’s Journey Toward Organic Farming and Environmental Advocacy

Thierry, 48, once farmed conventionally, like many in his family before him, burying chemicals in the soil as part of monoculture practices. After suffering financial ruin in 2005, he made a bold switch to organic agriculture and direct sales, building a cooperative that now supplies 460 families through the local AMAP network. His farm, six hectares strong, produces around fifty varieties of vegetables with help from five full-time employees.

Yet, his peaceful life was disrupted last May when an unannounced inspection by his organic certifier, Ecocert, revealed alarming signs: yellowing grass along irrigation canals adjacent to his neighbors’ plots—a telltale symptom of glyphosate contamination. Since the centuries-old flooded irrigation channels of the Crau are interconnected, there’s a real risk that chemical runoff could seep into Thierry’s land and jeopardize his organic status. The mere threat of losing his certification hangs heavily over him.

Speaking Out Against Pesticide Pollution—and Paying a Price

Thierry didn’t stay silent. For years, he has alerted neighbors, local officials, and agricultural authorities about the widespread use of herbicides in the region’s irrigation ditches and canals, armed with photographic evidence. Despite his efforts to raise the issue during local agricultural commission meetings and even offering to share less harmful alternatives like pelargonic acid for free, his warnings fell on deaf ears.

His activism has not gone unnoticed—for all the wrong reasons. Since being named as a whistleblower in a complaint filed against unknown parties suspected of illegal glyphosate spraying in irrigation canals, Thierry has faced threats and intimidation. “They told me they would ‘take care’ of me,” he recounts grimly. Fearful for his safety, he has even slept in his caravan to protect his property. He filed a police report for threats and insults in July, standing firm despite being labeled a “snitch.”

Laurence Suzanne, co-president of the Paniers Marseillais, a network supporting local farmers and consumers, defended Thierry: “He spoke for all of us. No one should bear these risks alone.” Yet political dialogue remains stalled—local agricultural officials have declined meetings, citing upcoming elections.

A Generation of Farmers Paying the Price

Thierry’s fight is deeply personal. Coming from a lineage of Italian farmers, he witnessed firsthand the devastating health impacts pesticides have wrought on his family. His father passed away in 2012 from lymphoma, officially linked to his occupational exposure to pesticides. Many relatives suffered cancers, Parkinson’s disease, and other chronic illnesses—a grim toll Thierry calls a “generation falling like flies.”

The subject remains taboo among farmers; during training sessions on pesticide use, Thierry observed colleagues physically blocking their ears when the instructor mentioned associated health risks. “Unlike asbestos in industry, where authorities eventually acted, no one is moving decisively on pesticides,” Thierry laments, blaming political inaction for allowing harmful chemicals to continue poisoning people slowly.

A Responsibility to His Community and Beyond

Today, Thierry is transparent with the 30 or so members who pick up their weekly vegetable baskets from his farm. He openly shares his worries—the threat to his organic label, his thyroid illness from pesticide exposure, and the mounting illnesses around him. His customers appreciate his honesty and support efforts like the “Zero Phyto in Our Canals” petition, which seeks to halt glyphosate use in irrigation channels and promote safer alternatives.

Despite some official reassurances that glyphosate use is minimal, and that mechanical weeding is the norm, the issue remains sensitive. The gravity-fed irrigation system in the Crau supplies water to 300,000 people, and no one wants to tarnish the reputation of the local hay producers. Thierry, who has actively participated in agricultural protests, believes the farming community itself must be willing to rethink entrenched practices to protect their future.


Thierry Gozzerino’s story is a powerful reminder of the human cost behind the pesticides debate—a call for transparency, courage, and change. In his hands, the soil remains alive and fertile, and with his voice, the hope for a healthier, pesticide-free future grows stronger.
