Paraquat
Paraquat is a herbicide used to control a large variety of broadleaf weeds, and annual and perennial grasses, in a variety of crops. It is currently used in commercial agriculture, forestry, and has reported use in urban weed control. Paraquat is also used as a pre-harvest desiccant.
This was a full reassessment that looked at the approvals for paraquat itself, and substances containing paraquat. In 2017, we declined an application for a herbicide containing paraquat due to its unacceptable risks to human health and the environment. This information was used to establish grounds for this reassessment application, which proceeded on to this reassessment.
After considering all relevant information available, including submissions from the public and presentations at a hearing, the Decision-making Committee decided to revoke a number of approvals and strengthen the controls on others.

Rules for paraquat use
Meteor
Meteor contains the active ingredient metamitron and is used as a plant growth regulator for thinning apples.
AgriNova New Zealand Ltd applied to reduce the restricted entry interval (the time required before workers can re-enter the field after spraying). The applicant was willing to reduce the maximum application rate in order to re-examine the appropriate restricted entry interval. New information about the properties of the substance was also provided.
