Abstract: Synergistic herbicidal agent comprises herbicides which are hydroxyphenylpyruvate dioxygenase inhibitors. Herbicidal agent contains: (A) at least one hydroxyphenylpyruvate dioxygenase inhibitor type herbicide of formula (I) or one of its salts; and (B) at least one herbicide which is: (a) selective in cereals against harmful monocot and/or dicot plants; (b) selective in maize against harmful monocot and/or dicot plants; (c) selective in rice against harmful monocot and/or dicot plants; or (d) non-selective on non-cultivated land and/or selective in transgenic crops against harmful monocot and/or dicot plants. The (A):(B) weight ratio is 1:2000-2000:1.
