Abstract
Isoxazolidinones of the following formula are herbicides: ##STR1## or an agriculturally acceptable salt thereof in which R.sub.1 and R.sub.2 are independently selected from -hydrogen and-halogen; and R.sub.3 is of the formula ##STR2## wherein n is 0 or 1, and when n is 0, PA0 W is selected from -hydrogen, -lower alkyl, -lower haloalkanoyl, and -benzoyl; PA0 X is selected from -hydrogen and -lower alkyl; and PA0 Y is selected from -hydrogen, -lower alkyl, -cycloalkyl, -lower alkanoyl, -lower haloalkanoyl, -benzoyl, -2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)benzoyl, -2,4-dichlorophenoxyacetyl, -lower alkyloxycarbonyl, -lower alkyloxycarbonyl, -lower alkylaminocarbonyl, -phenylaminocarbonyl, and -lower alkylthiocarbonyl; or PA0 W and X together constitute a chemical bond; and Y is selected from -nitrogen and -lower alkyloxycarbonyl; and when n is 1, PA0 X and Z together constitute a chemical bond; PA0 W is -hydrogen; PA0 V is selected from -hydrogen and -lower alkyl; and PA0 Y is selected from -lower alkyl, -phenyl, -carboxyl, and -lower alkyloxycarbonyl, or PA0 V and Y together are an alkyl chain of 4-6 carbon atoms.
