Syngenta, the producer of a herbicide banned in more than 70 countries and which has been linked to Parkinson\u2019s disease<\/a>, will stop selling paraquat in Australia, saying new regulations has made it \u201ccommercially unviable\u201d.<\/p>\n

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<\/a>.<\/p>\n

Paraquat has been produced by the Swiss company for decades, but has long been linked to Parkinson\u2019s disease in users<\/a>.<\/p>\n

It is banned in more than 70 countries and has been prohibited in the European Union since 2007.<\/p>\n

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\u2019s disease.<\/p>\n

But it did impose new restrictions to address acute exposure and risks to animals.<\/p>\n

The company said the decision to pull the products followed a commercial review carried out in the wake of the APVMA\u2019s rules.<\/p>\n

Syngenta ANZ\u2019s managing director, David Van Ryswyk, said the company will manage the phase-out of its paraquat products in strict alignment with the APVMA\u2019s designated sell-out and use-by timelines.<\/p>\n

\u201cRegulatory constraints, combined with a highly complex and increasingly expensive supply chain, have made the paraquat herbicide products commercially unviable,\u201d Van Ryswyk said.<\/p>\n

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.<\/p>\n

At the time of the APVMA\u2019s decision, Syngenta said<\/a> the pesticide \u201cdoes not cause an unacceptable environmental impact\u201d and that the regulation would limit its use in a significant number of crop use cases.<\/p>\n

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 unviable.<\/p>\n

Generic paraquat products will still be available for local farmers.<\/p>\n

Last month, the Melbourne neurologist Associate Prof Wes Thevathasan told the ABC that there has been \u201cglobal consensus\u201d in his field that exposure to paraquat was linked to the development of Parkinson\u2019s disease.<\/p>\n

\u201cThere are now multiple epidemiological studies or real-world exposure studies that have suggested that paraquat increases the risk of Parkinson\u2019s disease by around threefold,\u201d Thevathasan said.<\/p>\n

Grain Producers Australia spokesperson Andrew Weidemann said Syngenta\u2019s decision created uncertainty for local growers.<\/p>\n

\u201cIts withdrawal leaves some important questions about what happens next,\u201d he said.<\/p>\n

\u201cAustralia is a relatively small market, and decisions like this call future investment into question.<\/p>\n

\u201cIf 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.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Syngenta, the producer of a herbicide banned in more than 70 countries and which has been linked to…\n","protected":false},"author":2,"featured_media":822518,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[64,63,99],"class_list":["post-822517","post","type-post","status-publish","format-standard","has-post-thumbnail","category-business","tag-au","tag-australia","tag-business"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/822517","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=822517"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/822517\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/822518"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=822517"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=822517"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=822517"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
