Genetically engineered crops and pesticide use in U.S. maize and soybeans
The widespread adoption of genetically engineered (GE) crops has clearly led to changes in pesticide use, but the nature and extent of these impacts remain open questions. We study this issue with a unique, large, and representative sample of plot-level choices made by U.S. maize and soybean farmers from 1998 to 2011. On average, adopters of GE glyphosate-tolerant (GT) soybeans used 28% (0.30 k...
متن کاملImpacts of genetically engineered crops on pesticide use in the U.S. – the first sixteen years
Background: Genetically engineered, herbicide-resistant and insect-resistant crops have been remarkable commercial successes in the United States. Few independent studies have calculated their impacts on pesticide use per hectare or overall pesticide use, or taken into account the impact of rapidly spreading glyphosate-resistant weeds. A model was developed to quantify by crop and year the impa...
متن کاملExperiences and Prospects of Genetically Engineered Crops
The debate about genetically engineered (GE) crops has become increasingly polarized in the United States, Europe, and some developing countries. The debate polarization has not been resolved in and by the complex and seemingly divergent literature that examines the impacts of the actual and potential adoption and commercialization of GE crops in industrialized and non-industrialized countries....
متن کاملDetection and quantification of genetically engineered crops
Genetically modified organisms (GMOs) have recently attracted the attention of agricultural, medical and food scientists and governments of many countries in the world due to an increasing concern that the recombinant gene(s) inserted into an organism may result in unforeseen effects. Therefore, there is a need to regulate each transgenic event so that the officially approved events will be the...
متن کاملThe Realized Yield Effect of Genetically Engineered Crops: U.S. Maize and Soybean
Yield improvements are critical to ensuring food security for a growing world population especially in view of the increasing potential for use of land in biofuel production. Efforts to sustain the impressive rate of past productivity gains, epitomized by such successes as the Green revolution, are bound to rely on biotechnology innovations such as those responsible for the development of genet...
