Description:
The present invention relates to herbicides, particularly selective herbicides, which are suitable for controlling the growth of unwanted plants in crop plants.
It is known to use substituted dinitroaniline derivatives, phosphoric acids, pyridazones, substituted ureas, triazines and biscarbamates as herbicidal active ingredients.
However, their action is not always satisfactory.
I have now found that herbicides comprising a mixture of A.
