Globally, herbicide resistance to the Group 31 herbicide mode of action has been confirmed in 3 populations of Poa annua in Australia only.
To assist in delaying the onset of resistance, rotate with herbicides from other modes of action.
Consider using alternative methods of weed control to reduce weed numbers before applying herbicides.
The above recommendations should be incorporated into an Integrated Weed Management (IWM) program. In all cases try to ensure surviving weeds from any treatment do not set and shed viable seed. Keep to integrated strategies mentioned in this brochure including cultural weed control techniques to reduce the weed seedbank. Make sure you mix and rotate herbicides from different mode of action groups. Always consult the product label prior to use.
