* Refer: CropLife Australia Insecticide Resistance Management Review Group Mode of Action Classification for Insecticides

Monitor pest levels and do not spray unless pest thresholds are exceeded.

Rotate insecticide groups and do not use two consecutive applications of products with the same Mode of Action.

Integrate both chemical and non-chemical means of control as part of the overall control strategy. Examples are the use of predators/parasites and relevant cultural practices (crop hygiene, rotation of planted areas, and strategic time of planting).

    Notes regarding the application of insecticides:

  1. To ensure the most effective control of the pest:
  • Product labels should at all times be carefully read and adhered to;
  • Full recommended rates of registered insecticides should always be used; and
  • Ensure good coverage of the target area to maximise contact.

CropLife Australia’s Resistance Management Strategies provide a guide for crop protection product rotation through product groups. The strategies are a useful tool that supports farmers’ adoption of resistance management. All crop protection products must be handled and applied strictly as specified on the product label or APVMA permits.

These Resistance Management Strategies do not replace product labels. They are a guide only and do not endorse particular products, groups of products or cultural methods in terms of their performance. It is important to check with the Australian regulator’s (APVMA) product database for contemporary information on products and active constituents. The database can be sourced through www.apvma.gov.au

The information given in this strategy is provided in good faith and without any liability for loss or damage suffered as a result of its application and use. Advice given in this strategy is valid as at 10 June 2020. All previous versions of this strategy are now invalid.
