Simulating evolution of glyphosate resistance in Lolium rigidum II: past, present and future glyphosate use in Australian cropping (2003, background): “(Llewellyn & Powles, 2001) has meant that pre-sowing control with glyphosate has become even more critical.”
RIM: a bioeconomic model for integrated weed management of Lolium rigidum in Western Australia (2004, background): “With the recent dramatic increase in herbicide resistance (e.g. Llewellyn and Powles, 2001), all of the above options are being examined by farmers in Western Australia.”
Herbicide-Resistant Weeds: Management Tactics and Practices1 (2006, background): “In a 1998 Western Australian field survey of rigid ryegrass, population densities were unrelated to herbicide resistance, suggesting the availability of alternative herbicides, particularly trifluralin, to control HR rigid ryegrass (Llewellyn and Powles 2001).”
Incidence of Herbicide Resistance in Rigid Ryegrass (Lolium rigidum) across Southeastern Australia (2012, background): “…of action (MOA) such as the triazine (inhibition of photosynthesis at photosystem II) and dinitroaniline (inhibition of microtubule assembly) herbicides (Boutsalis and Broster 2006; Broster and Pratley 2006; Broster et al. 2011; Llewellyn and Powles 2001; Owen et al. 2007; Pratley et al. 1993).”
Widespread occurrence of multiple herbicide resistance in Western Australian annual ryegrass (Lolium rigidum) populations (2007, methodology): “The 1998 survey found that almost all ryegrass populations remained clethodim susceptible (Llewellyn and Powles 2001).”
Multiple herbicide‐resistant Lolium rigidum (annual ryegrass) now dominates across the Western Australian grain belt (2014, background): “In 1998, a random survey of crop fields across the 12 million hectare WA grain belt established widespread L. rigidum resistance to the ACCase- and ALS-inhibiting herbicides (Llewellyn & Powles, 2001).”
Multiple-herbicide resistance across four modes of action in wild radish (Raphanus raphanistrum) (2004, background): “In the WA wheatbelt, multiple-herbicide resistance is common in the worst grass weed, rigid ryegrass (Llewellyn and Powles 2001), and here we show that multiple resistance is now evident in the worst dicot weed, wild radish.”
Review: Confirmation of Resistance to Herbicides and Evaluation of Resistance Levels (2013, background): “…HR seed source (Baumgartner et al. 1999; Falk et al. 2005) to many regions within a state or province (Beckie et al. 1999, 2001; Bourgeois and Morrison 1997a, 1997b; Bourgeois et al. 1997b; Davis et al. 2008; Légère et al. 2000; Llewellyn and Powles 2001; Tucker et al. 2006; Walsh et al. 2001).”
Factors influencing adoption of conservation tillage in Australian cropping regions (2008, background): “2001; Llewellyn and Powles 2001), with costlier forms of multiple resistance (e.g. Walsh et al .”
Herbicide resistance in weeds endowed by enhanced detoxification: complications for management (2004, background): “…rigid ryegrass resistant to chlorsulfuron in Western Australia have demonstrated that almost all populations have targetsite resistance (Gill 1995; Llewellyn and Powles 2001), despite the fact that the first chlorsulfuron-resistant population of rigid ryegrass was shown to have resistance due to…”
Break-crop benefits to wheat in Western Australia – insights from over three decades of research (2012, background): “In addition the late 1980s and early 1990s resistance to the most commonly used selective grass herbicide diclofop-methyl (Hoegrass, Bayer Crop Science, Vic., Australia) was becoming more widespread (Gill 1995; Llewellyn and Powles 2001).”
