Summary

Herbicide resistance weeds are a major problem in the cropping regions of Australia with the rice industry no different to any of the other cropping industries in this regard. Identification of the underlying level of resistance in a region or cropping system aids in the understanding of herbicide resistance and in designing strategies for its management. To obtain this information weed seed samples of six different species will be collected from across the rice growing regions of southern NSW. After collection the weed seed samples will be screened to different herbicides to determine if resistance to those herbicides is present in the samples collected.

Findings of this screening will be provided to the Rice Research Committee, Rice Crop Protection Working Group, district agronomists, chemical companies and reseller and private agronomists.

Objective Summary

This project aims to determine the level of resistance in the major rice growing regions of southern New South Wales for the most important weeds to the most herbicides most commonly used for the control of those weeds.
