The Environmental Protection Authority (EPA) is seeking public submissions on a proposed new herbicide to control broadleaved weeds in fodder beet crops.
FMC New Zealand Limited has applied to import or manufacture Trifix Herbicide, which contains 500 g/kg of triflusulfuron methyl, a chemical new to Aotearoa New Zealand.
FMC says it offers greater flexibility for application timing and better control of broadleaved weeds in fodder beet, a crop widely used for livestock feed.
“This application is part of our ongoing commitment to assess products with new active ingredients, providing new crop protection tools for New Zealand’s vital primary sector,” says Dr Lauren Fleury, EPA Hazardous Substances Applications Manager.
The EPA has carried out risk assessments for the product and is now inviting feedback on this application.
If approved, Trifix Herbicide could only be used by professionals in commercial settings, and users would need to comply with specific controls.
Triflusulfuron methyl is approved for use in Canada and the United States.
As an agricultural compound, Trifix Herbicide must also receive approval from the Ministry for Primary Industries (MPI) before it can be used in New Zealand.
Dr Fleury says the EPA is making strong progress to increase efficiency in assessing applications, with eight applications for new active ingredients currently in progress.
“We understand the importance of timely access to new products and have set ambitious new targets to boost our performance in this area.”
Submissions close on Wednesday, 8 October 2025 at 11.59 pm.
