Subsequent trials were conducted with a different type of aircraft: the Breguet XIV, which had better stability and payload capacity than the Potez. Two Breguet XIV aircraft, serial numbers 10.11 and 10.69, were adapted by installing tanks holding 100 kg, and later 200 kg. These and subsequent devices were built at the Technical Bureau of the Military Gas Institute in Warsaw. In 1927, in the Włocławek Forest District, a Farman Goliath bomber was used with a dusting device installed inside the fuselage. Esturmit (or esternit) – a mixture of calcium arsenate and copper sulphate imported from Germany – was sprayed against the pine processionary moth. That same year, Breguet aircraft were used to protect sugar beet crops; the spraying device with a 250 kg powder tank was designed by Col. Wojnicz-Sianożęcki.

Since military aircraft had to be restored to their military functions after treatments, it was not possible to optimally adapt them for agricultural aviation work. No private enterprise in Poland undertook to design appropriate equipment, although the benefits of using aviation in agriculture and forestry were recognised. An interesting example of experiments using aircraft for the benefit of agriculture was the work of Dr Eng. Jadwiga Pitulanka. This pilot of the Kraków Aero Club conducted in-flight research on the airborne transport of small insects, which was intended to enable monitoring of the appearance and migration of crop pests.
