In most world crop-production areas, the evolution of herbicide-resistant weeds is becoming a major issue. This problem has become most severe across the Australian dryland crop-production region, where herbicide-resistant weed populations are threatening crop-production profitability and sustainability across 20 million ha. Widespread herbicide resistance has forced changes in agronomic and herbicide practices. This problem is particularly evident in Western Australia, where the frequency and… 

Management of herbicide resistance in wheat cropping systems: learning from the Australian experience.

The hard-learned lessons of Australian growers can now be viewed by global wheat producers as an example of how to stop the continual loss of herbicide resources in productive cropping systems, and there is evidence of a sustainable weed control future for wheat production systems.

Interactions between crop sequences, weed populations and herbicide use in Western Australian broadacre farms: findings of a six-year survey

Overall, the study indicated that land use selection and utilisation of associated weed management actions were being used successfully to control weeds within the survey area, however, to successfully manage herbicide resistant weeds land use has become less diverse, with pastures utilised less and crops with efficacious weed control options utilised more.

Current state of herbicides in herbicide-resistant crops.

From the onset of commercialization, growers must now preserve the utility of new technologies by integrating their use with other weed management technologies in diverse and sustainable systems.

Nonconventional Weed Management Strategies for Modern Agriculture

Abstract Weeds are a significant problem in crop production and their management in modern agriculture is crucial to avoid yield losses and ensure food security. Intensive agricultural practices,

Reducing the Risks of Herbicide Resistance: Best Management Practices and Recommendations

Herbicides are the foundation of weed control in commercial crop-production systems. However, herbicide-resistant (HR) weed populations are evolving rapidly as a natural response to selection

Opportunities and challenges for harvest weed seed control in global cropping systems.

HWSC systems can reduce weed populations substantially reducing the potential for weed adaptation and resistance evolution, and should be considered for inclusion in weed-management programs in many of the world's cropping regions.

Herbicide Resistance: Toward an Understanding of Resistance Development and the Impact of Herbicide-Resistant Crops

Development of herbicide-resistant crops has resulted in significant changes to agronomic practices, one of which is the adoption of effective, simple, low-risk, crop-production systems with less

Navigating a Critical Juncture for Sustainable Weed Management

Agricultural weed management has become entrenched in a single tactic—herbicide—resistant crops—and needs greater emphasis on integrated practices that are sustainable over the long term. In response



Efficacy of cultural control methods for combating herbicide‐resistant Lolium rigidum

Herbicide-resistant populations of annual ryegrass (Lolium rigidum) are estimated to affect crop production on about 5000 farms in southern Australia, and farmers have generally combined cultural practices for weed management with the use of alternative herbicides, mainly trifluralin.

No-tillage adoption decisions in southern Australian cropping and the role of weed management

Adoption of no-tillage sowing systems has increased rapidly in many Australian grain growing regions over the past decade. The extent of herbicide resistant weed populations in these regions has also

Potential for Preseason Herbicide Application to Prevent Weed Emergence in the Subsequent Growing Season. 1. Identification and Evaluation of Possible Herbicides1

It was determined that S-metolachlor had the potential to retain efficacy on rigid ryegrass seedlings after 12 wk of exposure on the soil surface to these conditions, and propyzamide had little or no effect on subsequently seeded wheat.

Reliability of higher seeding rates of wheat for increased competitiveness with weeds in low rainfall environments

Adoption of higher wheat seed rates as part of integrated weed management is now strongly promoted to farmers, and the probability of reduced crop grain size and increased proportion of small seeds was negligible at these densities.

Grain grower perceptions and use of integrated weed management

Greater adoption of integrated weed management, to reduce herbicide reliance, is an objective of many research and extension programmes. In Australian grain-growing regions, integrated weed

Improved management of Avena ludoviciana and Phalaris paradoxa with more densely sown wheat and less herbicide

The effectiveness of crop competition for better weed control and reducing herbicide rates was determined for Avena ludoviciana and Phalaris paradoxa and there was significant non-linearity of the response surface that differed for the weed species.

High Levels of Herbicide Resistance in Rigid Ryegrass (Lolium rigidum) in the Wheat Belt of Western Australia1

Herbicide-resistant rigid ryegrass populations are now more common than susceptible populations across much of the Western Australian wheat belt, reflecting different cropping and, therefore, herbicide use history.

Simulating evolution of glyphosate resistance in Lolium rigidum II: past, present and future glyphosate use in Australian cropping

A herbicide resistance model, parameterized for Lolium rigidum has been used to perform a number of simulations to compare predicted rates of evolution of glyphosate resistance under past, present and projected future use strategies, and found risks of glyphosate and paraquat resistance were reduced.

Multiple herbicide resistance in a glyphosate-resistant rigid ryegrass (Lolium rigidum) population

WALR 50 is the first glyphosate-resistant weed population with confirmed resistance to ACCase- and ALS-inhibiting herbicides, and a novel root growth–based assay of glyphosate resistance was developed and validated, giving a root growth GR50 R:S ratio of 3.4.

High Frequency of Chlorsulfuron-Resistant Wild Radish (Raphanus raphanistrum) Populations across the Western Australian Wheatbelt1

This test successfully identified chlorsulfuron-resistant populations of wild radish that are resistant to this herbicide using the Quick-Test technique, and validated the use of this test for a dicot species.
