1. Herbicidal compositions characterised in that they simultaneously contain, as active materials, 2.4-diamino-6-chloro-5-methylthiopyrimidine or a mixture of the two isomeric compounds 2.4-diamino-6-chloro-5-methylthiopyrimidine and 4.6-diamino-2-chloro-5-methylthiopyrimidine in which the first of these compounds is preponderant, and methyl diclofop, the weight ratio 2,4-diamino-6-chloro-5-methylthiopyrimidine/methyl diclofop or a mixture of the two isomeric compounds/methyl diclofop in the compositions being 1/5 to 5. |
