Access to weed killers crucial
THE Tasmanian agricultural community continues to express concerns over proposed restrictions on certain herbicides critical for managing invasive weeds and non-native plant species.
Since the mid-1960s, both Paraquat and Diquat have been widely used by farmers as essential tools to boost crop yields in paddocks and pastures.
Paraquat is commonly used to control weeds in grain, vegetable and fruit crops, while Diquat is used for winter cereals and pasture weeds following heavy grazing.
Maintaining practical access to these essential herbicides is vital for primary production.
Through the safe and effective use of such tools, Tasmania may enhance productivity and reach the State Government’s stated aim to increase the agricultural sector’s value to $10 billion annually by 2050.
However, access to these herbicides has recently come under a cloud following an announcement by the Australian Pesticides and Veterinary Medicines Authority in July to propose changes to guidelines and regulations governing their use.
The proposed regulatory decision suggests a dramatic reduction of up to 75 per cent in the rates of allowed use, as well as a total ban in crop desiccation.
This change would impact a range of commodities, particularly in the cropping and horticulture sectors, potentially reducing yields and affecting the economic viability of affected farms.
In order to influence the final decision, TasFarmers has submitted feedback to the APVMA on the proposed regulatory decisions regarding the two herbicides, advocating on behalf of farmers.
While we understand the APVMA review of the safety, efficacy and environmental impact of these products, we have argued that the economic and logistical consequences of reducing their use will be significant.
Any decision on this issue should be based in science, not politics.
The APVMA is highly regarded for its scientific rigour, and the industry needs political space for this independent regulator to operate effectively.
What the industry does not need is a regulatory decision lacking in proper scientific backing.
The industry is calling for the APVMA to be allowed to conduct a rigorous high-tier risk assessment of these chemicals to better represent the conditions and risks within the setting of Australian agriculture.
To enable this the Federal Government must ensure the proper funding of the body’s scientific undertakings, and the final decision to be science based.
Farmers are highly skilled in safely handling and applying these herbicides in compliance with stringent health and safety standards.
Ensuring the APVMA is well funded will allow for thorough, science-based risk assessments that accurately reflect the specific conditions of Australian agriculture.
The proposed restriction of Paraquat and Diquat use poses a significant challenge for farmers, potentially leading to higher production costs, reduced crop yields, and negative environ mental outcomes.
A more measured approach, focused on risk mitigation and improved safety practices, would better serve both the agricultural community and the broader public interest.
