Transgenic Crops for Herbicide Resistance
A year after the introduction of the first commercial transgenic crop (Flavr SavrTM tomato with a longer shelf life) in 1994, transgenic, herbicide-resistant crops (HRCs) were introduced (Table 3.1) with the introduction of bromoxynil(3,5dibromo-4-hydroxybenzonitrile) resistant cotton and glufosinate[2-amino-4(hydroxymethylphosphinyl)butanoic acid] resistant canola. Bromoxynil resistance had li...
متن کاملHerbicide Resistant Weeds and Crops
Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...
متن کاملHerbicide Metabolism in Weeds — Selectivity and Herbicide Resistance
The metabolic detoxication/bioactivation pathways, the levels and activity of enzymes, and endogenous cofactors mediating these reactions in crops have been well document‐ ed; however, much less evidence has been accumulated in weed species. The herbicide metabolism as a selectivity factor is summarized with special attention to acetyl-CoA car‐ boxylases (ACCase)-inhibiting aryloxyphenoxypropio...
متن کاملHerbicide use on roundup ready crops.
In his News Focus article "GM crops in the cross hairs" (26 Nov., p. 1662), Dan Ferber refers to the assessment by Charles Benbrook of the effect that the introduction of Roundup Ready crops has had on herbicide use, concluding that the benefits are not clear-cut. We disagree with this conclusion. Changes in herbicide use are largely meaningless unless relative environmental and health risks ar...
متن کاملHerbicide Safeners: Effective Tools to Improve Herbicide Selectivity
Herbicide safeners, formerly referred to as herbicide antidotes, are chemical agents that increase the tolerance of monocotyledonous cereal plants to herbicides without affecting the weed control effectiveness. The use of safeners offer several benefits to agricultural weed control. Safeners may allow: (1) the selective chemical control of weeds in botanically related crops; (2) the use of nons...
