The An-2 was originally intended as an agricultural aircraft, and in 1949 it got a set of appropriate equipment. For dusting 1400l hopper tank was installed. Tunnel type dispenser (right) allowed to cover field strip 18...22m wide.

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.

Any dusting and spraying equipment may be fitted on the same airframe, otherwise nearly identical to the barebone An-2T. The only difference is longer stroke landing gear, allowing to operate from the worst airfields.
