Title: Phenylglyoxylonitrile-2-oxime-cyanomethyl ether as a crop safener

Abstract: The new compound phenylglyoxylonitrile-2-oxime-cyanomethylether of the formula ##STR1## and compositions containing it, are used as a safener (antidote) for selectively combatting weeds in culture crops, especially sorghum and rice, in order to protect these cultivated plants from being injured by strong herbicides such as chloroacetanilides and thiolcarbamates. The safener is preferably applied to the crop seeds prior to planting.
