Illegal pesticides spread through Greek farms as Europe confronts a cross-border trade

A black market reaches Greek fields

Illegal pesticides are becoming more visible in northern Greece, where Euronews found that lower-priced products supplied through illicit networks are attracting farmers squeezed by rising production costs. These chemicals may be counterfeit, contain unauthorised active ingredients or enter the market without the required testing and labelling. Their appeal is straightforward: farmers facing narrow margins can buy them for less than approved alternatives. The wider costs, however, may fall on workers, consumers, soil, water systems and legitimate agricultural suppliers.

The development matters beyond Greece because the trade is organised across national borders. Counterfeiters can import raw materials, reproduce the packaging of recognised brands and move small consignments through routes designed to evade customs controls. Once a product reaches a farm, authorities may struggle to reconstruct its composition and origin. That weakens pesticide-residue monitoring and makes environmental damage more difficult to attribute, while honest growers face competition from operators using cheaper substances that do not meet European rules.

European investigations reveal the supply chain

Evidence from the European Anti-Fraud Office shows the scale and structure of the problem. In a documented investigation centred on Ukraine, authorities conducted 89 searches and seized hundreds of tonnes of illicit agrochemicals and production materials. OLAF said the products carried false labels resembling major European and American brands, while some raw materials had arrived from China. Investigators connected earlier seizures in Bulgaria and Romania to the larger production network and established a joint investigation team.

The official findings do not independently calculate the $20 billion global estimate used in the Euronews headline, so that figure should be treated as part of the outlet’s sourced assessment rather than an EU-verified total. The institutional evidence nevertheless confirms industrial-scale counterfeiting, cross-border distribution and material threats to food security, environmental safety and legitimate companies. It also demonstrates why isolated national inspections are insufficient: investigators must combine customs intelligence, product testing, financial tracing and cooperation between exporting and destination countries.

Enforcement and farm economics converge

The next question is whether enforcement can reduce supply without ignoring the economic pressure that creates demand. Greek and EU authorities can expand checks at ports, warehouses and online marketplaces, but farmers will continue looking for cheaper options if approved crop protection becomes unaffordable or ineffective. Better traceability, rapid laboratory testing and penalties aimed at distributors rather than unsuspecting buyers could narrow the market. Agricultural policy also matters: advice on lower-chemical alternatives and support for compliant products may be necessary to prevent another illicit supplier from replacing each network that police dismantle.
