Since 1975 3-channel RTSh-1 duster was introduced, providing 34...36m covered strip (picture at the top right).
Crops spraying (top left) performed via tube running under lower wing trailing edge. The tube is equipped with multiple replaceable dispensers. Propeller driven pump allows to dispense 18l of chemicals per second over 30m wide strip.
