Herbicidal compositions comprising an N,N-disubstituted alanine derivative and 2-ethylamino-4-(1-cyano-1-methyl ethylamino)-6-chloro-1,3,5-triazine or 2-ethylamino-4-(1-cyano-1-methyl ethylamino)-6-methylthio-1,3,5-triazine exhibit synergistic responses against wild oats. The addition of phenoxy-alkanoic acid derivatives, whether as racemate or R-(+)-isomers, causes an improved effect on yields without substantial loss of activity against wild oats.
