Syngenta, the producer of a herbicide banned in more than 70 countries and which has been linked to Parkinson’s disease, will stop selling paraquat in Australia, saying new regulations has made it “commercially un
The decision to pull the product follows new restrictions on the highly poisonous chemical announced by the Australian Pesticides and Veterinary Medicines Authority in June

Paraquat has been produced by the Swiss company for decades, but has long been linked to Parkinson’s disease in users
It is banned in more than 70 countries and has been prohibited in the European Union since 2007
It cannot be used in domestic settings in Australia, but is still widely used in agriculture, particularly broad-acre cropping like grains, sugarcane and cotton. The APVMA assessed that the weight of evidence does not show that paraquat exposure through approved uses increases the risk of developing Parkinson’s disease
But it did impose new restrictions to address acute exposure and risks to animals
The company said the decision to pull the products followed a commercial review carried out in the wake of the APVMA’s rules

Syngenta ANZ’s managing director, David Van Ryswyk, said the company will manage the phase-out of its paraquat products in strict alignment with the APVMA’s designated sell-out and use-by timelines
“Regulatory constraints, combined with a highly complex and increasingly expensive supply chain, have made the paraquat herbicide products commercially un
The new restrictions on the herbicide required that backpack sprayers be phased out, mandate additional personal protective equipment for users and set a much lower maximum rate of application per hectare
At the time of the APVMA’s decision, Syngenta said the pesticide “does not cause an unacceptable environmental impact” and that the regulation would limit its use in a significant number of crop use cases
The company had planned to continue supplying through a third-party manufacturer, but on Friday it said the new regulations and an increasingly expensive supply chain had made the product un
Generic paraquat products will still be available for local farmers
Last month, the Melbourne neurologist Associate Prof Wes Thevathasan told the ABC that there has been “global consensus” in his field that exposure to paraquat was linked to the development of Parkinson’s disease
“There are now multiple epidemiological studies or real-world exposure studies that have suggested that paraquat increases the risk of Parkinson’s disease by around threefold,” Thevathasan said
Grain Producers Australia spokesperson Andrew Weidemann said Syngenta’s decision created uncertainty for local growers
“Its withdrawal leaves some important questions about what happens next,” he said
“Australia is a relatively small market, and decisions like this call future investment into question
“If companies cannot see sufficient value in maintaining products here, growers risk being left with fewer choices at the same time we urgently need more tools to manage herbicide resistance.”
