A compound of the formula:

• ##SPC9##
• wherein
• R.sub.1 is selected from alkyl of 2 through 8 carbon atoms, alkenyl of 3 through 6 carbon atoms, alkynyl of 3 through through 6 carbon atoms, cycloalkyl of 4 through 8 carbon atoms, cycloalkenyl of 5 through 8 carbon atoms, cycloalkylmethyl of 4 through 9 carbon atoms, cycloalkenylmethyl of 6 through 9 carbon atoms, bicycloalkyl or bicycloalkenyl of 7 through 10 carbon atoms and bicycloalkylmethyl or bicycloalkenylmethyl of 8 through 11 carbon atoms, trimethylcyclohexyl and tetramethylcyclohexyl;
• the above alkyl groups substituted with one methoxy, ethoxy, methylthio or ethylthio group;
• the above cycloalkyl groups substituted with one alkyl of 2 through 4 carbon atoms, 1 through 2 methyl groups, 1 through 2 chlorines or bromines, one methoxy or one ethoxy group;
• and ##SPC10##
• wherein
• Q is hydrogen, fluorine, chlorine, bromine, alkyl of 1 through 4 carbon atoms, alkoxy or alkylthio of 1 through 2 carbon atoms, nitro or a trifluoromethyl group;
• Y is hydrogen, chlorine, or methyl;
• and
• Z is hydrogen or chlorine;
• R.sub.2 is hydrogen, alkyl of 1 through 3 carbon atoms or a cation selected from Na.sup.+, Li.sup.+, K.sup.+, (Ca/2).sup.+, ammonium and dimethylammonium;
• R.sub.3 is hydrogen, methyl or ethyl;
• R.sub.4 is alkyl of 1 through 4 carbon atoms, alkenyl of 3 through 4 carbon atoms, alkynyl of 3 through 4 carbon atoms, or methoxy;
• and
• X is oxygen or sulfur;
• provided that when X is sulfur, neither R.sub.2 nor R.sub.3 is hydrogen.
