N-substituted haloacyloxyacetamide compounds having the following formula: ##STR1## in which R.sub.1 is selected from the group consisting of chlorine and bromomethyl; R.sub.2 is selected from the group consisting of hydrogen, chlorine and bromine; R.sub.3 is selected from the group consisting of hydrogen, 1-4 carbon alkyl, 2-10 carbon alkenyl, and methylene malononitrile; R.sub.4 is selected from the group consisting of 1-10 carbon alkyl, 2-10 carbon alkenyl, 2-10 carbon alkynyl, and substituted phenyl wherein said substituents are chloro or 1-6 chloro alkyl; or R.sub.3 and R.sub.4 together with the nitrogen atom to which they are attached are selected from the group consisting of 4-10 carbon alkylene ring and 4-10 carbon alkyl substituted oxazolidine ring; provided that when R.sub.1 and R.sub.2 are chlorine, then R.sub.3 and R.sub.4 are other than allyl. The compounds are useful as herbicidal antidotes for protection of crops from thiocarbamate herbicidal injury.
