China’s pesticide drones ‘a godsend’ for struggling farmers amid labour shortage
Deployment of flying machines saves time and money and cuts back on pesticide use as exodus of young people to cities sparks rural labour shortage

Farmers in northern China have employed drones over their orchards this month to make up for rising labour shortage, and achieving remarkable increases in productivity in the process, the state news agency reported.
About a dozen unmanned aerial vehicles sprayed pesticide on apple trees in Ji county, Shanxi province at the rate of about 10 minutes per orchard, or 15 times the efficiency of manual labour.

Each drone carried a tank of the bug spray in its belly, and flew over paths calculated and operated by remote control.
“I have trudged in the dirt my whole life, and I have never seen anything like this,” Liu Xinzhu, a 60-year-old farmer told Xinhua.
Liu’s son had found a job in city, and his wife is not healthy enough for labour intensive work. Liu alone could not take care of his one-acre apple orchard.
