Abstract
Common sowthistle (Sonchus oleraceus)and fleabane (Conyza bonariensis) are common andproblematic broadleaf weeds in the northern grainsregion, infesting fallows and crops throughout muchof the year. A heavy reliance is placed on knockdownherbicides such as glyphosate and 2,4-D for the controlof these weeds. As a result, resistance to glyphosate hasbeen confirmed in both species and both are at risk ofdeveloping resistance to 2,4-D. In response, a GRDC funded field survey has been conducted in winter and summer grain crops from late-2016 to early-2018 to determine the extent of glyphosate and 2,4-D resistance across the northern grain region. In total, more than 500 sites have been surveyed in New South Wales Glyphosate and 2,4-D amine resistance in common sowthistle (Sonchus oleraceus) and fleabane (Conyza bonariensis) in the Northern Grain growing region of Australia.
