Pesticide Approvals Revoked
The Environmental Risk Management Authority has revoked approvals for the use of the pesticide methyl parathion in New
Zealand.
Methyl parathion is a broad-spectrum organophosphate pesticide used against insects and mites. Formulations containing
methyl parathion were first registered for use in New Zealand in 1961 but no products have been registered since 2004.
Methyl parathion is fatal in low concentrations if ingested or absorbed through the skin. It is very ecotoxic to aquatic
and soil organisms, birds and bees.
The European Union banned methyl parathion in 2003 and in the United States there was a voluntary agreement in 1999 not
to use it on crops that contributed most to children's diets.
The revocation of approvals was the result of ERMA New Zealand's Chief Executive Initiated Reassessment (CEIR) programme
in which hazardous substances are re-evaluated.
Public submissions were called for and eight received, all in favour of the approvals being revoked.
Other substances being re-evaluated under the CEIR programme include the fumigant methyl bromide and the insecticides
azinphos methyl, endosulfan, dichlorvos and trichlorfon and the herbicide methylarsinic acid.
