<p>Herbicidal agents contain (A) a 1,2-dimethyl-3,5-diphenylpyrazolium salt, 2-(cholor-3-74-chlorophenyl)propionic acid methyl ester, 2-(N-benzoyl-3,4-dichloroanilino)-propionic acid ethyl ester, 2-(N-benzoyl-3-chloro-4-fluoroanilino)propionic acid isopropyl ester, 2-(N-benzoyl-3-chloro-4-fluoroanilino)propionic acid methyl ester or 4-chloro-2-butynyl N-(3-chlorophenyl)-carbamate, (B) a synergistic amt. of a cpd. of formula (I) (where R is H, an equiv. of an inorganic or organic cation, or 1-6C alkyl; and X is H or Cl), and (C) usual adjuvants and/or carrier substances. Used as selective herbicides for combatting grassy weeds, esp. wild oasts in cereal cultures. The combinations have an effect on wild oats which is less dependent on the stage of growth than known herbicides. In surviving weed plants, seed production is more completely suppressed. Tolerance by cereal crop plants is good, so that the combinations give an improved margin of safety.</p> |
