Abstract

A survey of non-agricultural areas including roadsides, railway right-of-ways and irrigation channels was conducted across Australia to investigate the extent of glyphosate resistant weed species. A total of 150 windmill grass and 84 fleabane populations were collected from QLD, NSW, VIC, SA and WA. A total of 7% of the windmill grass and 52% of the fleabane populations contained individuals resistant to glyphosate. Of 186 populations of annual ryegrass collected from SA, NSW and WA, 50% were found to contain high numbers of resistant individuals. A small number (9) of barnyard grass populations were also collected from northern NSW, with 3 populations found to be resistant. Glyphosate resistance in these non-agricultural areas has the ability to spread into other areas, such as crops, and cause management difficulties elsewhere. Therefore, the large amount of resistance found in this study highlights the importance for the development and application of management strategies for these areas.
