Application to reassess the insecticide Actara


We are seeking your views on a reassessment application to change controls for the insecticide Actara.

The Ministry for Primary Industries has applied to modify some controls so Actara can be used during an incursion of the brown marmorated stink bug.

The submission period closes on Tuesday 6 December 2022 at 11.59 pm.

The application

Actara contains the active ingredient thiamethoxam, a neonicotinoid insecticide, and is currently approved in New Zealand with controls.

The brown marmorated stink bug is one of the highest-risk biosecurity threats currently facing New Zealand, as it can cause significant damage to many important horticultural crops. It is also a significant social nuisance pest that can adversely impact personal wellbeing.

The application seeks to change two controls currently in place for Actara:

  • An increase in the maximum number of applications of Actara (within any one target area) from four to 19 applications per year.
  • An exemption from a control prohibiting application of an agrichemical where bees are foraging or on plants that are in flower or likely to flower.

The applicant requests these proposed changes are only made available to the Ministry for Primary Industries (Biosecurity New Zealand) for use in responding to a brown marmorated stink bug incursion.
