The Environmental Protection Authority (EPA) is taking another look at the use of some chemicals in aquatic herbicides, following significant new information on their effects.
It has established grounds to reassess the following chemicals:
- diquat dibromide
- metsulfuron-methyl
- haloxyfop-R-methyl
- imazapyr isopropylamine
- triclopyr triethylamine
The EPA’s General Manager for Hazardous Substances and New Organisms, Dr Chris Hill, says, “The information we now have on the effects of these chemicals when used in aquatic herbicides was not available when we last reassessed them in 2013. Since then, the European Union has banned the use of diquat based on concerns about the effects of exposure to people and birds.
“We also believe there is some inconsistency across aquatic herbicide approvals in Aotearoa New Zealand that needs to be addressed,” he said.
“Now that the EPA has established grounds for reassessment, the next step will be to open a public call for information to find out who is using aquatic herbicides containing these chemicals, and where.
“We will then analyse the responses and prepare a reassessment application, which we anticipate will be open for public submissions next year.”
