Fungicide and bactericide modes of action

The accompanying table lists fungicide and bactericide active ingredients currently available for crop protection in New Zealand in groups according to shared risk from resistance development in target pests. The group codes are intended for use on pesticide labels to help in the prevention and management of pesticide resistance in New Zealand. Information used in constructing these tables came from publicly available information from the Fungicide Resistance Action Committee and CropLife Australia.

The New Zealand Committee on Pesticide Resistance (NZCPR) is a subcommittee of the New Zealand Plant Protection Society (NZPPS). Neither NZCPR or NZPPS guarantees that the information in these tables is accurate or up-to-date, or accepts any liability for loss or damage arising from the use information contained in these tables.

Use of Group Codes on pesticide product labels

For any product that contains an active ingredient at risk from resistance development, the product label should include a statement about resistance prevention or management. This statement should begin with the mode of action or activity group(s) of the at-risk ingredient(s), as in the following example:

Resistance prevention or management
Product_name contains the GROUP 14 insecticide, dicloran. Do not use another product containing a fungicide in the same group in conjunction with Product_name when applying the resistance prevention or management guidelines below.
[Details of the resistance guidelines for this product then follow]
