Tension over chemical impact

GRAIN Producers Australia has voiced their strong support for the Australian Pesticides and Veterinary Medicines Authority’s decision to extend the review of Paraquat and Diquat from early 2025 until late 2025. 

This delay follows a stream of nearly 170 submissions from their public consultation process, including farmers and grain growers, urging them to consider the role the chemicals play in the Australian grain industry. 

APVMA stated that it was committed to a “rigorous evidence-based review process” to evaluate all relevant data, including the latest studies on the environmental impact of these herbicides. 

GPA said that Paraquat and Diquat were essential herbicides used widely in Australia, particularly in minimum-till cropping systems. They said grain producers in Tasmania and across the nation relied on these chemicals, along side glyphosate, to manage weeds effectively in challenging conditions, including low rainfall. 

GPA Southern Grower Director Andrew Weidemann recognised the importance of the delay and said it was important for the national regulator to take the extra time needed to ensure the final decision was right. 

Despite this support from some of the farming sector, there are growing concerns about the potential health risks associated with the use of Paraquat and Diquat for human health. 

Some studies have linked pro longed exposure to Paraquat with serious health conditions, including Parkinson’s disease. 

The debate surrounding these chemicals highlights the tension between agricultural needs and health and safety concerns. 

While many in the agricultural industry argue that these chemicals are vital for maintaining productivity, many note a need to understand their potential for long-term health impacts. 

As the APVMA moves toward a final decision by the end of 2025, they said they are hopeful that the extended review period will allow for a deeper understanding of the role of herbicides in modern farming practices while protecting the health of farmers and consumers. 

For now, GPA are optimistic the review process will lead to a balanced outcome that supports the future of sustainable agriculture and the farmers’ health.
