Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]

New Phytologist, 2009
Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.

Mechanisms of evolved herbicide resistance [PDF]

Journal of Biological Chemistry, 2020
The widely successful use of synthetic herbicides over the past 70 years has imposed strong and widespread selection pressure, leading to the evolution of herbicide resistance in hundreds of weed species. Both target-site resistance (TSR) and nontarget-site resistance (NTSR) mechanisms have evolved to most herbicide classes.

Herbicide resistance: Development of wheat production systems and current status of resistant weeds in wheat cropping systems

Crop Journal, 2019
Herbicide resistance in crops has extended the scope of herbicide applications to control weeds. The introduction of herbicide resistant crops resulted in a major shift in the way that herbicides are used in many crops, but not necessarily increased the ...

Segmentation of Sandplain Lupin Weeds from Morphologically Similar Narrow-Leafed Lupins in the Field

Remote Sensing, 2023
Narrow-leafed lupin (Lupinus angustifolius) is an important dryland crop, providing a protein source in global grain markets. While agronomic practices have successfully controlled many dicot weeds among narrow-leafed lupins, the closely related ...

Herbicide resistance cases in South Africa: A review of the current state of knowledge

South African Journal of Science, 2023
Herbicides play a major role in weed management worldwide. However, herbicide resistance is a global challenge that threatens weed management and sustainable agriculture.

Herbicide Resistance Management in Florida Tomato Production

EDIS, 2020
Herbicide resistance was historically not a significant issue in most horticultural crops because few herbicides were applied. Close proximity of agronomic crops and the loss of methyl bromide has led to a gradual increase in herbicide inputs and the ...

Agricultural Weed Assessment Calculator: An Australian Evaluation

Plants, 2020
Weed risk assessment systems are used to estimate the potential weediness or invasiveness of introduced species in non-agricultural habitats. However, an equivalent system has not been developed for weed species that occur in agronomic cropland ...

Novel α-Tubulin Mutations Conferring Resistance to Dinitroaniline Herbicides in Lolium rigidum

Frontiers in Plant Science, 2018
The dinitroaniline herbicides (particularly trifluralin) have been globally used in many crops for selective grass weed control. Consequently, trifluralin resistance has been documented in several important crop weed species and has recently reached a ...

Evidence for an ecological cost of enhanced herbicide metabolism in Lolium rigidum [PDF]

, 2009
1. In some cases, evaluation of resource competitive interactions between herbicide resistant vs. susceptible weed ecotypes provides evidence for the expression of fitness costs associated with evolved herbicide-resistant gene traits. Such fitness costs
