Abstract
Herbicidal compositions comprising an active herbicidal compound and antidote therefor and the methods of use; the antidote compound corresponds to substituted oxazolidines and thiazolidines having the formula ##SPC1## In which X is oxygen or sulfur; R is haloalkyl, alkyl or alkylthio; and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are independently selected from the group consisting of hydrogen, lower alkyl, alkoxyalkyl and lower alkylol.
Claims67
An herbicidal composition comprising an active thiocarbamate herbicidal compound and an antidote therefor corresponding to the formula ##SPC4##
- in which X is oxygen or sulfur, R is haloalkyl having 1 to 10 carbon atoms, inclusive, and the term halo includes chloro and bromo substitutions, alkyl having 1 to 10 carbon atoms, inclusive, or alkylthio having 1 to 4 carbon atoms, inclusive;
- R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are independently selected from the group consisting of hydrogen, lower alkyl having 1 to 4 carbon atoms, inclusive, alkoxyalkyl having a total of 2 to 4 carbon atoms, inclusive, and lower alkylol having 1 to 4 carbon atoms, inclusive.
The method of protecting a crop from injury due to a thiocarbamate herbicide, comprising applying to the crop seed prior to planting a non-phytotoxic antidotally effective amount of a compound corresponding to the formula ##SPC5##
- in which X is oxygen or sulfur;
- R is haloalkyl, alkyl, alkylthio;
- and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are independently selected from the group consisting of hydrogen, lower alkyl, alkoxyalkyl and lower alkylol.
The method of protecting a crop from injury due to a thiocarbamate herbicide, comprising preplant incorporation in the soil in which said crop is to be planted, a non-phytotoxic antidotally effective amount of a compound corresponding to the formula ##SPC6##
- in which X is oxygen or sulfur;
- R is haloalkyl, alkyl, alkylthio;
- and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are independently selected from the group consisting of hydrogen, lower alkyl, alkoxyalkyl and lower alkylol.
