<p>K 1377 Herbicidal compositions comprising as active ingredients an R-(+)-isomer of a phenoxy-alkanoic acid derivative, e.g., a (dimethylamine) salt of R-(+)- (4-chloro-2-methylphenoxy)propionic acid or R-(+)- (2,4-dichlorophenoxy)propionic acid, and an N,N-di-substituted alanine derivative, e.g., N-benzoyl-N- (3-chloro-4-fluorophenyl)alanine esters, especially the methyl and isopropyl ester, exhibit a significantly reduced antagonism with respect to the effect of the alanine compound on oats whilst maintaining the activity against broad-leaved weeds which makes a single postemergence application effective.</p> |
