Zusammenfassung:Compounds of the formula wherein R is C1-C4 alkyl, CH2CH=CH2, CH2C IDENTICAL CH, cyclopropylmethyl or CH2CH2R2; R1 is C1-C2 alkyl, C1-C2 haloalkyl, CH2CN, CH2OCH3, C1-C3 alkoxy, C1-C3 alkylthio, phenylthio or NR3R4; R2 is C1-C2 alkoxy, C1-C2 alkylthio, CN or halogen; R3 and R4 are independently H or CH3; and X is NHCH3, N(CH3)2 or N(CH3)OCH3; provided that when R1 is OCH2CH3 or CH2OCH3, then R is other than CH3; and their agriculturally suitable salts. exhibit herbicidal activity. They have particular utility for the selective control of weeds in beet.
