The sector of use of the bioherbicide broadcaster is agriculture. It is an appliance which works without nozzles. It generates a closed spraying-agent circuit, so that no spraying agent escapes outwards. Functioning is based on the fact that the spraying agent flows out of a tank through a pipe onto a spreading disc which rotates. The arrangement of some steps results in a spreading mist. The broadcast spreading agent is intercepted again by a frame and pumped back into the tank. The appliance is mounted behind a tractor and is set in such a way that the frame sweeps precisely over the entire flora. Now, when the tractor travels over a field or meadow, only the projecting weeds protrude into the spreading mist. In this way, only the stubborn weeds are wetted in a fully controlled manner. The entire remaining environment remains protected from the spraying agent. There is no other spraying method which takes place in such a controlled and such an economical way. After the frame has been removed, an outstanding liquid-manure broadcaster is obtained.
