Impact of GE Crop Adoption on Quality-Adjusted Herbicide Use in U.S. Corn Production [PDF]

This paper presents findings on the use of HT corn and quality-adjusted herbicide use for 12 key corn producing states using a panel data set for 1986-2008.

The first RNAi‐based biopesticide approved in the United States: regulatory implications for the European Union – the case of Ledprona (Calantha™)

Pest Management Science, EarlyView.
The approval of the RNA interference‐based biopesticide Ledprona (Calantha™) in the USA marks a milestone for RNA‐based crop protection. We discuss the regulatory implications for the European Union, highlighting opportunities, challenges, and the need for adapted risk assessment frameworks for RNA‐based plant protection products.

Identifying resistance‐conferring cytochrome P450s in weeds: experimental strategies and practical considerations

Pest Management Science, EarlyView.
Identifying resistance‐conferring cytochrome P450s requires integrating weed characterization, gene discovery and functional validation. No single approach is sufficient to distinguish causal resistance genes from herbicide‐metabolizing enzymes. Abstract Cytochrome P450 monooxygenases (P450s) play a pivotal role in metabolic herbicide resistance, yet ...

Development of herbicide resistant crops through induced mutations

Advancements in Life Sciences, 2015
Herbicide resistance is an innate characteristic of crop plants. It enables them to survive and propagate even in the presence of lethal doses of herbicides in the surroundings. Genetic tolerance in crops towards herbicides may have several benefits.

An introduction to the farm-scale evaluations of genetically modified herbicide-tolerant crops

, 2003
1. Several genetically modified herbicide-tolerant (GMHT) crops have cleared most of the regulatory hurdles required for commercial growing in the United Kingdom.

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

Persistence of seed‐applied pesticides in soybeans: environmental influences and implications for crop protection

Pest Management Science, EarlyView.
Early soybean planting in cool, wet soils slows emergence and results in about half the insecticide and fungicide concentrations at vegetative emergence compared with standard planting, where faster emergence maintains roughly double the pesticide concentrations, yet pesticide persistence remains similar across both planting dates.

Field and biochemical evaluation of glyphosate tolerant chickpea (Cicer arietinum L.) mutants developed through induced mutagenesis

BMC Plant Biology
Weed control in chickpea (Cicer arietinum L.) is challenging due to narrow genetic base of available germplasm and limited herbicide options. In this view, present research was focused on induced mutagenesis in chickpea for development of herbicide ...

Effects of biotechnology on biodiversity: herbicide-tolerant and insect-resistant GM crops [PDF]

, 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 continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
