Herbicide 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...
متن کاملMilestones in the Development of Herbicide Safeners*
The concept o f using chemical safeners to improve herbicide selectivity became widely known in 1969 with the introduction o f naphthalic anhydride (N A ) to improve the tolerance o f maize to thiocarbamate herbicides. Soon thereafter dichlormid was also developed as a safener for thiocarbamates in maize. At present there are at least eight different chemical safeners that have been developed c...
متن کاملAn Overview of the Mechanisms of Action of Herbicide Safeners
Herbicide safeners are chemicals used for manipulating the tolerance of large-seeded grass crops to selected soil-applied herbicides. The physiological interactions of herbicides and their respective safeners are characterized by the following facts: a) safeners are most effective when applied prior to or simultaneously with the herbicides whose injury they prevent; b) safeners exhibit a high d...
متن کاملDetoxification without intoxication: herbicide safeners activate plant defense gene expression.
Plants are frequently exposed to natural and synthetic toxins such as heavy metals, allelochemicals, organic pollutants, and pesticides. Consequently, plants must mount specific and coordinated defense mechanisms for survival under adverse growing conditions (Zhang et al., 2007). One such mechanism is the capability for metabolizing organic compounds from abiotic origin (xenobiotics). Extensive...
متن کاملInduction of glutathione S-transferases in Arabidopsis by herbicide safeners.
Herbicide safeners increase herbicide tolerance in cereals but not in dicotyledenous crops. The reason(s) for this difference in safening is unknown. However, safener-induced protection in cereals is associated with increased expression of herbicide detoxifying enzymes, including glutathione S-transferases (GSTs). Treatment of Arabidopsis seedlings growing in liquid medium with various safeners...
