HERBICIDAL COMPOSITIONS
The present invention provides compositions comprising herbicidally active compounds (A) and (B), where (A) represents one or more compounds of the general formula (I) or agrochemically compatible salts thereof [component (A)], and (B) represents one or more herbicides [component (B)]. The application further relates to a method and to the use of the herbicidal composition according to the invention for controlling harmful plants or for regulating growth.

Method for producing a solid herbicide formulation
The invention relates to a method for producing a solid herbicide formulation containing a) a herbicide from the group of sulfonylurea, or the salts thereof which are useful in the agricultural domain, b) optionally at least one other herbicide, c) optionally a safener, and d) at least one formulation adjuvant. A suspension is formed in water, consisting of the sulfonylurea a), optionally at least one other herbicide b), optionally a safener c) and at least one formulation adjuvant d). The suspension is adjusted to a pH value between 6.5 and 8 by adding an acid or a base, and is then dried to obtain the solid formulation.
