|Group*||Chemical sub-group||Example chemical|
*Refer: CropLife Australia Expert Committee on Insecticide Resistance Mode of Action Classification for Insecticides
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.
3. Seek advice from the manufacturers and/or government advisory services to determine local resistance levels for particular mode of action Groups.
4. DO NOT exceed the maximum number of applications permitted on the insecticide label.
5. 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.
6. When using insecticides/aphicides to control other pests consider the effect on beneficial insects and the potential to flare aphid populations.
7. For more information about insecticide resistance in the green peach aphid refer to http://cesaraustralia.com/latest-news/all/insecticide-resistance-in-the-green-peach-aphid
8.
