Modelling evolution and management of glyphosate resistance in Amaranthus palmeri [PDF]

, 2011
A population-based model was developed to simulate the evolution of glyphosate resistance in populations of Amaranthus palmeri. Model parameters were derived from published and unpublished sources, and the model was implemented using previously ...

Embedded Pesticide Use: Exploring the Pesticide‐Land Nexus

Journal of Agrarian Change, EarlyView.
ABSTRACT Since the turn of the century, global land grabs, farmland financialization and land‐based food sovereignty movements have returned the land question to the heart of agrarian studies. Meanwhile, abiding interest in pesticides has been reanimated in the face of changes in production, regulation and knowledge of toxicity.

Characterization of Glyphosate Resistance in Hordeum glaucum Steud (Barley grass) [PDF]

, 2021
Hordeum glaucum Steud. is a major grass weed in South Australia in crops and pastures across the agricultural region. Control of this grass species has become a problem in recent decades as a consequence of the evolution of herbicide-resistance to ...

Target and Non-Target Site Mechanisms Developed by Glyphosate-Resistant Hairy beggarticks (Bidens pilosa L.) Populations from Mexico

Frontiers in Plant Science, 2016
In 2014 hairy beggarticks (Bidens pilosa L.) has been identified as being glyphosate-resistant in citrus orchards from Mexico. The target and non-target site mechanisms involved in the response to glyphosate of two resistant populations (R1 and R2) and ...

Remaking State Power Through a Paraquat Ban in Malaysia

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper examines the role of the state in its ability to enact environmental regulations. Specifically, this study investigates how Malaysian state actors changed, shifted and betrayed various, oftentimes competing interests to ban paraquat, an acutely toxic herbicide.

Degradation of pesticides by the ligninolytic enzyme Laccase : optimisation of in vitro conditions, immobilisation and screening for natural mediators [PDF]

, 2013
Pesticides are widely used in many industries but the majority reaches non-target organisms or locations through point or diffuse sources. Understanding conditions for their degradation is therefore important.

Pesticide Supply Chains From China to Australia: Examining Paraquat Amid the Global Pesticide Complex

Journal of Agrarian Change, EarlyView.
ABSTRACT Following recent calls to deepen understanding of the Global Pesticide Complex, this article delves into the China‐to‐Australia supply chain of a single herbicide—paraquat. First released in the United Kingdom in the 1960s, acutely toxic paraquat is now primarily produced in China.

Differential response of two sourgrass populations to glyphosate [PDF]

Communications in Plant Sciences, 2013
The repetitive use of glyphosate may cause increase on the resistance of sourgrass (Digitaria insularis) through mechanisms of natural selection. The aim of this study was to verify the response of two populations of sourgrass (one collected from ...

Protecting While Promoting? The Limits of Agroindustry‐Driven Pesticide Safety in Ugandan Smallholder Agriculture

Journal of Agrarian Change, EarlyView.
ABSTRACT Pesticide use is expanding rapidly across sub‐Saharan Africa, while regulatory oversight and public protection structures remain weak, leaving smallholder farmers exposed to mounting health and environmental risks. In response, agrochemical industry actors have launched ‘safe use’ initiatives that emphasize training and personal protective ...
