Genetically Modified Herbicide-Tolerant Crops, Weeds, and Herbicides: Overview and Impact
Environmental Management, 2015Genetically modified (GM) crops have been and continue to be a subject of controversy despite their rapid adoption by farmers where approved. For the last two decades, an important matter of debate has been their impact on pesticide use, particularly for herbicide-tolerant (HT) crops. Some claim that these crops bring about a decrease in herbicide use,

Herbicide-tolerant crops-real farmer opportunity or potential environmental problem?
Pest Management Science, 1998Classical breeding, in-vitro selection and genetic engineering techniques have produced herbicide-tolerant crops. Commercial adoption of these cultivars in North America provides tolerance predominantly to non-selective herbicides for novel weed-control strategies.

Effects of biotechnology on biodiversity: herbicide-tolerant and insect-resistant GM crops
Trends in Biotechnology, 2005 Biodiversity is threatened by agriculture as a whole, and particularly also by traditional methods of agriculture. Knowledge-based agriculture, including GM crops, can reduce this threat in the future. The introduction of no-tillage practices, which are beneficial for soil fertility, has been encouraged by the rapid spread of herbicide-tolerant ...

Herbicide Drift from Genetically Engineered Herbicide-Tolerant Crops
Environmental Science & Technology, 2021In recent years, off-target herbicide drift has been increasingly reported to lead to damage to nontarget vegetation in the U.S. These reports have coincided with the widespread adoption of genetically modified crops with new herbicide-tolerance traits.

Engineering herbicide tolerance into crops
Trends in Biotechnology, 1990Abstract Herbicide treatments of crops allow economic weed control and provide cost-effective increases in agricultural productivity. Although herbicides currently in use combine a high degree of effectiveness with favourable production costs, non-toxicity and rapid biodegradation, they often lack selectivity, thus limiting their use to pre-emergence ...

Effects of Herbicide-Tolerant Crop Cultivation
2016Overall, this work identifies key points to be taken into account when drawing up guidelines that govern the use of herbicide-tolerant (HT) crops in order to preserve the effectiveness of this innovation over time. This multidisciplinary expert report, based on an international literature review, assesses the effects of the cultivation of crops ...

Herbicide Tolerance in Crops: A Commercial Reality
1999Weed infestation of crops causes extensive loss in the production of our food. Estimations range from 10 to 30% of crop yield annually. Despite a multitude of herbicides being available to farmers, there are considerable limitations in their effectiveness.

Production of herbicide-tolerant crops faulted
Chemical & Engineering News Archive, 1990A coalition of farm and environmental groups—including such diverse bodies as the National Wildlife Federation, Environmental Defense Fund, and Foundation on Economic Trends—has issued a report cri...

Herbicidal inhibitors of amino acid biosynthesis and herbicide-tolerant crops
Amino Acids, 2006Acetohydroxyacid synthase (AHAS) inhibitors interfere with branched-chain amino acid biosynthesis by inhibiting AHAS. Glyphosate affects aromatic amino acid biosynthesis by inhibiting 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Glufosinate inhibits glutamine synthetase and blocks biosynthesis of glutamine.
