Serrated tussock resistance to flupropanate in Australia - is the genie out of the bottle?

Detailed regional surveys to assess the extent of serrated tussock resistance to flupropanate have been conducted in Armidale (NSW), Diggers Rest (Victoria) and the Rowsley Valley (Victoria). Results show that serrated tussock resistance to flupropanate is becoming widespread with implications of greater serrated tussock invasion, increased herbicide usage, increased management and labour costs for farmers as a consequence. Integrated weed management and a national project to raise awareness of the serrated tussock resistance to flupropanate are discussed.
