Herbicide Evaluation in Arkansas Cotton, 1999 [PDF]

, 2000
Herbicidal weed control is economically important for production of cotton. Field experiments are conducted annually in Arkansas to evaluate the activity of developmental and commercial herbicides for selective control of weeds in cotton.

Glyphosate- and aminomethylphosphonic acid (AMPA)-induced mortality and residues in juvenile brown trout (Salmo trutta f. fario) exposed at different temperatures

Environmental Sciences Europe
Background Glyphosate is a broad-spectrum, non-selective systemic herbicide with a commonly assumed low potential for accumulation in biota. Nevertheless, glyphosate has been shown to bioaccumulate in the tissues of several organisms.

Effects of glyphosate and endosulfan on soil microorganisms in soybean crop Efeitos do endosulfan e glyphosate sobre microrganismos do solo na cultura da soja

Planta Daninha, 2008
Transgenic soybean, resistant to glyphosate, is the most dominant transgenic crop grown commercially in the world. Research works on herbicide and insecticide mixtures and their effects on microorganisms are rarely reported.

Analysis of multiple-herbicide resistant Amaranthus palmeri populations from Spain points to an introduction of the eccDNA from America. [PDF]

Pest Manag Sci
In this study, multiple herbicide resistant mechanisms have been confirmed in two Amaranthus palmeri populations from Spain that survived glyphosate‐ and ALS‐inhibitor herbicides. Our data suggest that the eccDNA and the mutations identified in the ALS gene are the result of an evolutionary event that occurred outside Spain.

Farmer behavior toward herbicide‐free agriculture and conservation tillage

American Journal of Agricultural Economics, EarlyView.
Abstract Balancing conflicting policy goals is a key challenge in the transition to sustainable agricultural systems. An important example is herbicide use reduction potentially conflicting with conservation tillage—which often strongly relies on herbicide use.

The “Pesticide Chip”: Chemical Legacies and Agrarian Futures in Costa Rica

Antipode, EarlyView.
Abstract For decades, agro‐industrial capital has adopted cascading chemical and biotechnical interventions, or fixes, to secure accumulation through the cultivation of monocrops. We develop a framework that centres on how monocrop‐induced susceptibility to pests and pathogens—and the patchwork of fixes to address these—produces uneven chemical ...

Historical evidence of glyphosate exposure from a US agricultural cohort

Environmental Health, 2019
In response to the recent review by Gillezeau et al., The evidence of human exposure to glyphosate: A review, Environmental Health 1/19/19, here we report additional glyphosate biomonitoring data from a repository of urine samples collected from United ...

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

Biological Reviews, EarlyView.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.
