The EPA consulted on proposed restrictions for bifenthrin, a synthetic pyrethroid insecticide used in kiwifruit orchards to help control cicada and passionvine hopper eggs. The proposed changes were aimed at reducing environmental risks associated with bifenthrin, particularly its potential effects on waterways and non-target species.
In our submission, we acknowledged the environmental concerns identified by the EPA and supported measures to strengthen stewardship and reduce risk. However, we noted that bifenthrin remained an important tool for kiwifruit growers, particularly for the management of passionvine hopper.
We emphasised that bifenthrin was not used as a routine in-season spray in kiwifruit production. Strict maximum residue limits effectively confined its use to the pre-flowering period, while growers were encouraged to adopt integrated pest management practices that prioritise non-chemical and lower-risk control methods before considering targeted bifenthrin applications.
We also emphasised the importance of maintaining access to bifenthrin as part of New Zealand’s broader biosecurity preparedness, including for the potential management of brown marmorated stink bug.
We encouraged the EPA to adopt strengthened controls that would manage environmental risks while retaining grower access to bifenthrin when needed.
