Compounds corresponding to the formula: ##SPC1## In which R.sub.1 and R.sub.2 are, independently, hydrogen, alkyl, alkoxyalkyl, cycloalkyl, pinonyl, ethylcycloalkyl, lower alkenyl, halogenated lower alkyl, benzyl, ethylphenyl, 2,4-dichlorophenoxy-methylene, styryl, furyl, phenyl or substituted phenyl in which the substituents are nitro, halogen, methyl, or methoxy; R.sub.3 and R.sub.4 are, independently, hydrogen or lower alkyl; X and Y are independently oxygen or sulfur; and Z is halogen, nitro, amino, lower alkyl, lower alkoxy or trifluoromethyl and n is an integer having a value from 0 to 4. The above compounds are effective herbicides, particularly for the control of grasses and broadleaf plants with both pre-emergence and post-emergence activity. Representative compounds are: m-propionamidobutyranilide, m-bis-2,2-dimethylvaleranilide, m-isobutyramido trichloroacetanilide, m-isobutyramido-2-ethylbutyranilide, m-t-butylacetamidopropionanilide, and 3'-N-ethyl propionamido-propionalide. This application is a continuation of application Ser. No. 180,916, filed Sept. 15, 1971, which is a continuation of application Ser. No. 20,104, filed Mar. 16, 1970, which is a continuation-in-part of application Ser. No. 741,267, filed July 1, 1968, which is a continuation-in-part of application Ser.
