Guidelines:
| Crop Stage | Group* | Chemical Sub-group | Example chemical |
|---|---|---|---|
| Seed Treatment (or in-furrow) | 4A 1B 2B | Neonicotinoids or organophosphates or phenylpyrazoles | imidacloprid dimethoate fipronil |
| Bare Earth (Preemergent) | 1B 3A | organophosphates or synthetic pyrethroids | omethoate bifenthrin |
| Early Season (Autumn when limited green growth) | 1B 3A | organophosphates or synthetic pyrethroids | chlorpyrifos alpha-cypermethrin |
| Spring | 1B 3A | organophosphates or synthetic pyrethroids | omethoate gamma-cyhalothrin |
*Groups are the International Resistance Action Committee Insecticide Groups based on mode of action of the insecticides – refer MoA tables.
If both autumn and spring applications are needed, alternate between synthetic pyrethroids and organophosphates

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 27 June 2019. All previous versions of this strategy are now invalid.
