Reduced herbicide rates: present and future
Julius-Kühn-Archiv, 2014 Applying herbicides at rates lower than the label recommendation has been the rule rather than the exception in Denmark since the late 1980’s. Justifications for reducing herbicide rates can be 1) that the dominant weed species in the field are very ...

Hierarchical modelling of species sensitivity distribution: development and application to the case of diatoms exposed to several herbicides [PDF]
arXiv, 2015 The Species Sensitivity Distribution (SSD) is a key tool to assess the ecotoxicological threat of contaminant to biodiversity. It predicts safe concentrations for a contaminant in a community. Widely used, this approach suffers from several drawbacks: i)summarizing the sensitivity of each species by a single value entails a loss of valuable information

Proceedings of the Integrated Crop Management Conference, 1998 Although herbicides have been an important component oflowa crop production for more than 30 years, the degree of reliance on these ag chemicals has increased significantly in the past decade. The primary cause of this increased reliance is the decrease in the use of tillage as a weed management tool. While this has benefits in terms of protecting soil

SpectroGLY: A Low-Cost IoT-Based Ecosystem for the Detection of Glyphosate Residues in Waters [PDF]
Glyphosate contamination in waters is becoming a major health problem that needs to be urgently addressed, as accidental spraying, drift or leakage of this highly water-soluble herbicide can impact aquatic ecosystems. Researchers are increasingly concerned about exposure to glyphosate and the risks its poses to human health, since it may cause ...

The Canadian Journal of Chemical Engineering, EarlyView.Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

Crop Journal, 2021 Herbicide resistance in crop plants is valuable for integrated weed management in agriculture. Herbicide resistant rice, in particular, is important to management of weedy rice, a close relative of cultivated rice and a noxious weed prevalent in rice ...

Julius-Kühn-Archiv, 2016 In 2011, a long-term field trial started in a winter wheat monoculture at Pettenbrunn, north of Freising, to examine the population and resistance dynamic of black-grass (Alopecurus myosuroides). Four different herbicide regimes and two different tillage

Clinical Pharmacology &Therapeutics, EarlyView.Clinical inhibition and genetic variation of the Breast Cancer Resistance Protein (BCRP/ABCG2) efflux transporter can significantly influence drug exposure, highlighting the need for reliable BCRP functional biomarkers. This study aimed to identify and evaluate biomarkers predictive of BCRP function in humans.

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 ...

AgronomyThe repeated application of herbicides has led to the development of herbicide resistance. Models are useful for identifying key processes and understanding the evolution of resistance. This study developed a spatially explicit model at a landscape scale
