ABSTRACT:
In a device for applying plant-protecting compositions and the like, having a tank for carrier fluid, for example water, and a feed pump that pumps carrier fluid from this tank through a pipe to which spray nozzles are connected, and having a metering pump that is connected by a connecting pipe to a preparation container and is driven by the carrier fluid supplied by the feed pump, in order to avoid a complicated apparatus for controlling the concentration of the preparation in the carrier fluid and to achieve reliable and accurate metering, the metering pump (5) is connected in series with the feed pump (2) so that the whole of the carrier fluid flowing through the pipe (3) passes through the metering pump (5), wherein the carrier fluid drives a drive element (12) in the metering pump (5), which in turn drives a metering mechanism (13, 14) which is connected to the connecting pipe (10) leading to the preparation container (11) and is provided with a setting sleeve (15) for the concentration of the preparation.
