Abstract
Abstract This invention discloses new compounds of the formula ##STR1## WHEREIN R 1 is selected from the group consisting of alkyl, cycloalkyl, alkenyl, haloalkyl, alkoxy, alkylthio, alkylsulfonyl and alkylsulfinyl; R 2 is selected from the group consisting of alkyl, alkenyl, haloalkyl and ##STR2## wherein R 4 and R 5 are each selected from the group consisting of hydrogen and alkyl; p is an integer from 0 to 3; Y is oxygen or sulfur; R 3 is selected from the group consisting of alkyl and halogen; and q is an integer from 0 to 2. Further disclosed is the herbicidal utility of the foregoing compounds.
