Assessing the cleanability of a direct nozzle injection system

► The cleanability of a system that directly injects pesticides locally at all nozzles was tested. ► The concentration of a simulated pesticide in the rinsing water was measured over time. ► Initial pesticide concentrations in the rinsing water of DIS will require further dilution. ► It takes more than 10 min to completely clean a 3 m test section.
