Abstract

Abstract HERBICIDAL USE OF COMPOUNDS OF THE FORMULA (RN-C6H4-SO2-N-CO-N(-R2)-R'')(-) HN(+)(-R6)(-R7)-R8 WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF CHLORO, CARBON ATOMS, ALKOXY HAVING A MAXIMUM OF FOUR CARBROMO, IODO, CYANO, ALKYL HAVING A MIXIMUM OF FOUR BON ATOMS, NITRO, AMINO AND THE GROUP -NH-CO-R3 WHEREIN R3 IS HYDROGEN OR ALKYL HAVING A MAXIMUM OF FOUR CARBON ATOMS, N IS THE INTEGER ONE TO THREE, PROVIDED THAT WHEN N IS ONE, R IS SUBSTITUTED IN THE 4''-POSITION OF THE PHENYL RING, R'' AND R2 ARE EACH INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL HAVING A MAXIMUM OF TWELVE CARBON ATOMS, ALKOXY HAVING A MAXIMUM OF FIVE CARBON ATOMS, ALKYNYL HAVING AT LEAST THREE AND A MAXIMUM OF FIVE CARBON ATOMS, CYCLOALKENYL HAVING AT LEAST FIVE AND A MAXIMUM OF SEVEN CARBON ATOMS, CYCLOALKYL HAVING AT LEAST FIVE AND A MAXIMUM OF SEVEN CARBON ATOMS, MONO SUBSTITUTED CYCLOALKYL SAID SUBSTITUENT BEING ALKYL HAVING A MAXIMUM OF FOUR CARBON ATOMS, PHENYL, SUBSTITUTED PHENYL HAVING A MAXIMUM OF THREE SUBSTITUENTS SAID SUBSTITUENTS BEING SELECTED FROM THE GROUP CONSISTING OF ALKYL HAVING A MAXIMUM OF FOUR CARBON ATOMS, BROBROMINE AND THE ROUP FOUR CARBON ATOMS, TRIFLUOROMETHYL, PHENOXY, MONO AND DIHALOGENATED PHENOXY SAID HALOGEN BEING CHLORINE OR BROME AND THE GROUP -OOC-N(-R4)-R5 SAID GROUP BEING IN THE 3-POSITION WHEREIN R4 AND R5 ARE EACH INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL HAVING A MAXIMUM OF FOUR CARBON ATMS, R6 R7 AND R8 ARE EACH INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL HAVING A MAXIMUM OF TWELVE CARBON ATOMS, ALKENYL HAVING A MAXIMUM OF SIX CARBON ATOMS PROVIDED THAT THE ACETYLENIC LINKAGE IS NOT ON THE CARBON ATTACHED TO THE NITROGEN, HYDROXYALKYL HAVING A MAXIMUM OF SIX CARBON ATOMS, TWO OF THE GROUPS R5, R6 AND R7 CAN BE JOINED TOGETHER TO FORM AN ALKYLENE HAVING FOUR TO SEVEN CARBON ATOMS, PROVIDED THAT WHEN TWO OF THE GROUPS R5, R6 AND R7 ARE JOINED TOGETHER THE REMAINING GROUP IS HYDROGEN, AND FURTHER PROVIDED THAT THE GROUPS R5, R6 AND R7 ARE NOT ALL HYDROGEN.
