- Rotate between registered insecticides that have different modes of action (eg. Group 1, Group 4, Group 9, Group 12A (cotton crop only), Group 23, Group 28, and Group 29.
- Do not apply consecutive applications of insecticides that have the same mode of action within and between seasons or exceed the recommended maximum number of applications in a crop.
- Do not follow a seed/seedling/soil treatment with a foliar application from the same Group when aphids are present.
- The Modes of Action (groups) and registered insecticides for control of cotton/melon aphid and/or green peach aphid are listed below.
Group* Chemical sub-group < strong >
Example Chemical 1A Carbamates pirimicarb 1B Organophosphates methamidophos 4A Neonicotinoid imidacloprid 4C Sulfoxaflor sulfoxaflor 9B Pymetrozine pymetrozine 12A Diafenthiuron diafenthiuron 23 Tetronic and Tetramic acid derivatives spirotetramat 28 Diamide cyantraniliprole 29 Flonicamid flonicamid
1. There is known cross-resistance between Groups 1A and 1B. Rotate between Group 1 and Group 4, 9B, 12A, 23, 28, and 29.
2. Consecutive applications of a Group 4A and Group 4C product may be made only if no other effective option is available – either because
a) no other group is registered in the crop or
b) the target pest is resistant to the other groups.
Seek advice from the manufacturers and/or government advisory services to determine local resistance levels for particular mode of action Groups.
3. Do not exceed the maximum number of applications permitted on the insecticide label.
4. When using insecticides/miticides to control other pests, consider the chemical group in relation to contributing to resistance development of Cotton/Melon Aphid and Green Peach Aphid.
5. When using insecticides/aphicides to control other pests consider the effect on beneficial insects and the potential to flare aphid populations.
6.

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
