The recent development of Group A and M multiple-resistant annual ryegrass serves as a stark reminder that persistent use of any herbicide mode of action group can cause resistance... The purpose of the experiment was to determine the best Group A treatments for the control of glyphosate-resistant barnyard grass, when treated at the mid to late tillering growth stage... The purpose of the experiment was to confirm which Group A herbicides provide satisfactory control of glyphosate-resistant barnyard grass under field conditions, and to compare results with those obtained from the glasshouse experiment...

Wild radish has developed resistance to many herbicide modes of action... Populations resistant to glyphosate have recently been confirmed... An autumn tickle can be conducted using a range of equipment including tyned implements, skim ploughs, heavy harrows, pinwheel (stubble) rakes, dump rakes and disc chains...

Professor Powles told participants that glyphosate is still working well on the majority of WA farms, but stressed that growers and advisers need to diversify its use with other herbicide modes of action and non-herbicide weed-control tactics to preserve its effectiveness in the long term... Random surveys of WA grainbelt paddocks by AHRI researcher Mechelle Owen in 2010 found seven per cent of 362 annual ryegrass (Lolium rigidum) samples had glyphosate resistance... In 2013, as part of a glyphosate, paraquat (Group L) and 2,4-D (Group I) resistance project, Department of Agriculture and Food, WA (DAFWA) senior research officer Dr Sally Peltzer coordinated a targeted pre-harvest survey across WA's cropping areas to raise awareness about the spread of glyphosate resistance in the state...

The cross resistance profile to pre-emergence herbicides has been examined in a multi-resistant population of annual ryegrass after pyroxasulfone recurrent selection... Recurrent selection with pyroxasulfone at below-label doses has resulted in pyroxasulfone resistance and cross-resistance to prosulfocarb and triallate... We suggest that herbicide rotation at the full label rate of prosulfocarb, pyroxasulfone, triallate and trifluralin in conjunction with weed seed control at harvest is currently the most sustainable solution for pre-emergence herbicide control of annual ryegrass in cereals...
