Abstract: The present invention relates to an apparatus for mixing a first (8) and a second agrochemical component (6). The apparatus comprises at least one first vessel (4) for accommodating the first component (8) and one second vessel (5) for accommodating the second component (6), the first (4) and the second vessel (5) being delimited with respect to one another by a connecting region such that the connecting region, in a closed basic state, does not permit a passage of compounds from the second into the first vessel and, in an open state, permits the passage of compounds. Here, the connecting region has a predetermined breaking point (7) formed such that it is intact in the closed basic state and such that it breaks open, causing the connecting region to adopt the open state, when a pressure above a certain threshold pressure is applied.
