Sorghum Safeners

Herbicide safeners, also termed antidotes in some texts, are chemicals that, when applied before or with herbicides, increase the tolerance of a cereal crop to a herbicide. This activity has been known since the 1970s and the safening effect is not seen on the weeds. A list of herbicide safeners available as commercial products is given in Table 4.2.
