Haloacyl and thiohaloacyl aryl-substituted oxazolidines and thiazolidines - herbicidal antidotes

The method of protecting a crop from injury, said injury due to a thiolcarbamate herbicide, comprising application to the soil in which crop is to be planted and grown, a non-phytotoxic antidotally effective amount of a compound corresponding to the formula ##STR12## wherein R is haloalkyl having 1 to 6 carbon atoms, inclusive, halo is chloro or bromo or chloroalkenyl;

• R.sub.1 is hydrogen, lower alkyl having 1 to 4 carbon atoms, inclusive, phenyl, naphthyl, substituted phenyl wherein said substituents are mono-fluoro, mono- or di-chloro, nitro, methyl, methoxy, or hydroxyl;
• R.sub.2 is hydrogen or lower alkyl having 1 to 4 carbon atoms, inclusive;
• R.sub.3 is hydrogen, hydroxymethyl, N-methylcarbamoyloxymethyl or dichloroacetoxymethyl;
• R.sub.4 is hydrogen, or lower alkyl having 1 to 4 carbon atoms, inclusive;
• R.sub.5 is hydrogen, lower alkyl having 1 to 4 carbon atoms, inclusive or phenyl;
• and R.sub.6 is hydrogen;
• provided that at least one of R.sub.1 or R.sub.5 is phenyl, substituted phenyl or naphthyl;
• said compound being antidotally active with said thiolcarbamate herbicide compound and wherein said compound is present in an amount between about 0.0001 to about 30 parts by weight of antidote compound per each part by weight of herbicide.
