Direct injection systems for Plant Protection Products (PPP) are developed to increase precision in application, to prevent the operator from contact with the chemical agents and to protect the environment against harm. They can be divided by the point where the PPP is injected in the pipes. These injection points cause different volumes of spray mixture in the piping system and therewith different response times until the desired spray mixture exits the nozzle. For sensor-based application, a short response time of the sprayer and variable rate application of different active ingredients are necessary.
