Stock Photo - 03 July 2020, Saxony-Anhalt, Bernburg: A drone flies over an experimental field of the Anhalt University of Applied Sciences. The unmanned flying object drops capsules containing chalcid wasp eggs every few metres. The chalcid wasps serve as biological plant protection, because after hatching the larvae eat the eggs of the corn borer, which is considered a pest and has so far been combated with chemical plant protection. The use of the drone is intended to minimize the use of chemical pesticides. Photo: Klaus-Dietmar Gabbert/dpa-Zentralbild/ZB. - Bernburg/Saxony-Anhalt/Germany
