Journal ArticleDOI
Photoinhibition of Photosynthesis Induced by Visible Light
TL;DR: In this article, a photo-inhibition from exposure to a high PFD without adding additional additional stress is described, which is caused by interaction between light and other environmental factors.
Journal ArticleDOI
Evolution in Action: Plants Resistant to Herbicides
Stephen B. Powles,Qin Yu +1 more
TL;DR: Understanding resistance and building sustainable solutions to herbicide resistance evolution are necessary and worthy challenges to herbicides sustainability in world agriculture.
Journal ArticleDOI
Glyphosate: a once-in-a-century herbicide.
TL;DR: The use of this virtually ideal herbicide is now being threatened by the evolution of glyphosate-resistant weeds, and adoption of resistance management practices will be required to maintain the benefits of glyphosate technologies for future generations.
Journal ArticleDOI
Reducing the Risks of Herbicide Resistance: Best Management Practices and Recommendations
Jason K. Norsworthy,Sarah M. Ward,David R. Shaw,Rick Llewellyn,Robert L. Nichols,Theodore M. Webster,Kevin W. Bradley,George B. Frisvold,Stephen B. Powles,Nilda R. Burgos,William W. Witt,Michael Barrett +11 more
TL;DR: In this article, the authors proposed a multifaceted approach to mitigate the evolution of herbicide resistance by reducing selection through diversification of weed control techniques, minimizing the spread of resistance genes and genotypes via pollen or propagule dispersal, and eliminating additions of weed seed to the soil seedbank.
Journal ArticleDOI
Evolved resistance to glyphosate in rigid ryegrass (Lolium rigidum) in Australia
TL;DR: Following 15 yr of successful use, glyphosate failed to control a population of the widespread grass weed rigid ryegrass in Australia and the presence of glyphosate resistance in a major weed species indicates a need for changes in glyphosate use patterns.
