Syngenta exits Australian paraquat market citing regulatory constraints and supply costs
Dedicating significant resources to unprofitable legacy products is no longer sustainable
Why would a major chemical company simply walk away from a market it's dominated for decades?
Because the math stopped working. Syngenta faced new regulatory rules that made the product harder to sell, and their supply chain had become so expensive that they couldn't turn a profit anymore. Sometimes it's not about the product itself—it's about whether you can afford to keep making it.
But paraquat is still legal. Other companies are still selling it. So what's different about Syngenta's situation?
Scale and history. Syngenta was the reliable, established supplier. They had infrastructure, reputation, customer relationships. When you're a smaller manufacturer or a generic producer, you can operate on thinner margins. Syngenta decided those margins weren't worth the complexity anymore.
What does this actually mean for the farmers who relied on them?
Uncertainty, mainly. They'll still be able to buy paraquat, but from different sources—mostly Chinese manufacturers now. That changes the supply chain, the reliability, potentially the cost. And there's the regulatory work: the APVMA imposed new label requirements, and Syngenta used to handle a lot of that. Now farmers have to figure it out themselves.
Is the APVMA's decision to restrict paraquat what pushed Syngenta out?
It was the final piece. The restrictions made the product harder to market and more expensive to comply with. But Syngenta was already struggling with supply costs. The regulatory tightening just made an already difficult business case impossible.
Do you think other suppliers will step in, or is this a permanent loss?
That's the open question. Generic manufacturers might expand, but they operate differently than Syngenta did. The market will probably survive, but it won't look the same. And farmers will bear more of the burden—both in terms of cost and in managing the regulatory compliance themselves.
O Pulso
- Syngenta has announced it will cease all paraquat sales in Australia and New Zealand, ending a supplier relationship that has anchored the market for decades.
- New APVMA restrictions on active ingredient concentrations and withholding periods made the product commercially unworkable, even after Syngenta had already shifted to a third-party manufacturer following the closure of its UK production facility.
- Generic alternatives exist, but the revelation that most now originate from China has unsettled farmers who valued Syngenta's stability and are wary of supply chain fragility.
- The regulatory label changes require costly implementation work that will now fall to farmers and industry rather than to the departing company.
- Regulators have been asked to comment on the market implications, and it remains uncertain whether other manufacturers will meaningfully fill the gap Syngenta leaves behind.
One of the world's largest agrochemical companies has quietly withdrawn from a market it helped define, leaving farmers in Australia and New Zealand to reckon with what it means when a reliable anchor departs. Syngenta's exit from paraquat sales — prompted by tightened regulatory conditions and an increasingly costly supply chain — is less a dramatic rupture than a slow unravelling of a decades-long commercial relationship. The herbicide itself remains available through generic suppliers, yet the question of who bears the cost of transition, and who absorbs the uncertainty of a market now leaning heavily on Chinese-sourced alternatives, falls squarely on the shoulders of those who work the land.
Syngenta, among the world's largest agrochemical companies, is withdrawing from the Australian and New Zealand paraquat market. The decision follows the Australian Pesticides and Veterinary Medicines Authority's tightening of restrictions on the herbicide last month — restrictions that, while not finding evidence of Parkinson's disease risk under safe use conditions, rendered the product economically unworkable for Syngenta to continue supplying.
Managing director David Van Ryswyk described the exit as a business calculation: regulatory constraints combined with a complex and costly supply chain had made paraquat commercially unviable. The company had already announced in March that it would close its UK production facility and transition to a third-party manufacturer for Australian supply. That arrangement, too, is now ending. Resources devoted to unprofitable legacy products, Van Ryswyk said, would be redirected elsewhere.
For farmers, the departure of a long-established supplier creates genuine uncertainty. Generic paraquat products will remain on the market, but Andrew Weidemann — a Western Victorian farmer and Grain Producers Australia spokesman — noted that most alternatives now originate from China, raising questions about reliability and cost. The loss of Syngenta as a stable presence compounds those concerns.
Weidemann also pointed to the practical burden of the APVMA's new label requirements — changes to active ingredient concentrations and withholding periods for late-season applications — which will demand significant industry effort and expense, now without Syngenta's participation. Whether other manufacturers will step in to stabilise the market, or whether farmers face a narrower supplier base and higher costs, remains an open question.
Syngenta, one of the world's largest agrochemical companies, is pulling out of the Australian and New Zealand paraquat market. The decision, announced Friday, comes after the Australian Pesticides and Veterinary Medicines Authority tightened restrictions on the herbicide last month. The regulator found no evidence that paraquat increases Parkinson's disease risk when used safely under its new conditions, but the tighter rules have made the product economically unworkable for Syngenta to continue supplying.
Managing director David Van Ryswyk framed the exit as a straightforward business calculation. The combination of regulatory constraints and a supply chain that has become both complex and prohibitively expensive has rendered paraquat products commercially unviable, he said. The company had already announced in March that it would cease global paraquat production at its UK facility by the end of June. At that time, Syngenta committed to serving Australian farmers through a third-party manufacturer. That arrangement is now ending as well. "Dedicating significant resources to unprofitable legacy products is no longer sustainable," Van Ryswyk said, adding that the company would redirect those resources elsewhere.
For Australian and New Zealand farmers, the departure of a company that has anchored the paraquat market for decades creates real uncertainty. Generic versions of the herbicide will remain available—other manufacturers continue to produce and sell them in Australia. But that supply picture comes with a significant caveat. Andrew Weidemann, a Western Victorian farmer and spokesman for Grain Producers Australia, noted that while multiple paraquat products exist, most now originate from China. The loss of Syngenta as a stable, long-established supplier raises questions about market reliability and the cost structure of alternatives.
Weidemann's concerns extend beyond simple supply availability. The APVMA's new restrictions include changes to active ingredient concentrations and withholding periods for late-season applications. Implementing those label changes across the industry will require substantial work and expense—work that will now fall to farmers and other industry players rather than to Syngenta. "Some of the changes in grams active and the withholding periods on late applications in crop, that work will fall clearly on the feet of the industry," Weidemann said. "So it's going to be a cost and that's going to be something that we as the industry will have to work through."
Syngenta said it would manage the phase-out of its paraquat products in strict compliance with the APVMA's sell-out and use-by deadlines. The regulator has been asked for comment on the company's departure and its implications for the broader market. What remains unclear is whether other manufacturers will step in to fill the gap left by Syngenta's exit, or whether Australian farmers will face a narrower range of suppliers and higher costs as they adapt to the new regulatory environment.
