Predictions of Biodiversity Response to Genetically Modified Herbicide-Tolerant Crops
Science, 2000We simulated the effects of the introduction of genetically modified herbicide-tolerant (GMHT) crops on weed populations and the consequences for seed-eating birds. We predict that weed populations might be reduced to low levels or practically eradicated, depending on the exact form of management.

Developing Herbicide-Tolerant Crop Cultivars: Introduction
Weed Technology, 1992In recent years considerable research in the private and public sectors has been directed toward introducing herbicide tolerance into normally susceptible crop species (9). Interest in developing herbicide-tolerant crop cultivars, clones, or hybrids (HTCs)3has been spurred by the reduction in the rate of discovery of new herbicidal compounds, the ...

Impact of Herbicide Tolerant Crops on Soil Health and Sustainable Agriculture Crop Production
2014Genetically modified (GM) crops and conservation tillage adoption can have individual, combined, and synergistic impacts on agricultural systems. The objective of this chapter is to evaluate the impacts of these technologies on the environment and economic returns.

The use of cytochrome P450 genes to introduce herbicide tolerance in crops: a review
Pesticide Science, 1999Mechanisms of herbicide resistance include (1) modified target site, (2) enhanced detoxification or delayed activation, and (3) alterations in the uptake, translocation, or compartmentalization of a herbicide. The first two mechanisms have mainly been identified in plants.

Optimizing Herbicide Use in Herbicide-Tolerant Crops: Challenges, Opportunities, and Recommendations
2019Rapid, large-scale adoption of herbicide-tolerant (HT) cropping systems is attributed to recent shifts in herbicide use patterns globally. With the dramatic increase in herbicide use, particularly glyphosate, herbicides’ diversity for weed management has consequently declined, resulting in increased herbicide-resistant (HR) weed species, weed ...

Epa's Response to Resistance Management and Herbicide-Tolerant Crop Issues
Weed Technology, 1992The regulation of transgenic plants is at the very early stages of dialog between the U.S. Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), and the U.S. Department of Agriculture (USDA). Herbicide resistance is discussed in the broader terms of resistance management and of the cooperative efforts underway involving ...
