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 ...

Drought exposure leads to rapid acquisition and inheritance of herbicide resistance in the weed Alopecurus myosuroides

Ecology and Evolution, 2022
Globally, herbicide resistance in weeds poses a threat to food security. Resistance evolves rapidly through the co‐option of a suite of physiological mechanisms that evolved to allow plants to survive environmental stress.

Current Status of Herbicide Resistance in the Iberian Peninsula: Future Trends and Challenges

Agronomy, 2022
The evolution of herbicide resistance in weeds has emerged as one of the most serious threats to sustainable food production systems, which necessitates the evaluation of herbicides to determine their efficacy.

Herbicide Resistance Management: Recent Developments and Trends

Plants, 2019
This review covers recent developments and trends in herbicide-resistant (HR) weed management in agronomic field crops. In countries where input-intensive agriculture is practiced, these developments and trends over the past decade include renewed ...

Molecular Mechanisms of Herbicide Resistance [PDF]

Weed Science, 2015
Resistance to herbicides occurs in weeds as the result of evolutionary adaptation (Jasieniuk et al. 1996). Basically, two types of mechanisms are involved in resistance (Beckie and Tardif 2012; Délye 2013). Target-site resistance (TSR) is caused by changes in the tridimensional structure of the herbicide target protein that decrease herbicide binding ...

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

TOTAL PROTEIN ANALYSIS AND TRANSMISSION ELECTRON MICROSCOPY AS METHODS FOR DETECTION OF CLODINAFOP-PROPARGYL HERBICIDE RESISTANCE IN THE GREEN ALGA Scenedesmus quadricauda [PDF]

Journal of Plant Protection and Pathology, 2012
Green alga cultures of Scenedesmus quadricauda were treated with different concentrations of clodinafop-propargyl herbicide (0, 10.5 21, 42 and 84 ppm). Transmission electron microscopy and total protein analysis were applied to clarify the resistance of

A bibliometric analysis of herbicide resistance in Africa

Scientific African, 2023
Herbicides were introduced in the 1950s, and since then, there has been an increase in herbicide-resistant weeds. This is apparent from the multiple (503) literature reviews on herbicide resistance worldwide.

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

Weed Science, 2012
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 dependency on tillage and lower energy requirements. Overall, the changes have had a positive environmental effect by reducing soil erosion, the fuel use for ...
