“We estimated the number of agricultural drones operating in some of the world’s leading agricultural countries by scouring online news and trade publications in many different languages. This effort revealed where agricultural drones have already taken off around the world.

Historically, most agricultural technology – tractors, for example – has spread from high-income countries to middle- and then lower-income ones over the course of many decades. Drones partially reversed and dramatically accelerated this pattern, diffusing first from East Asia to Southeast Asia, then to Latin America, and finally to North America and Europe. Their use in higher-income regions is more limited but is accelerating rapidly in the U.S. 

China leads the world in agricultural drone manufacturing and adoption. In 2016, a Chinese company introduced the first agriculture-specific quadcopter model. There are now more than 250,000 agricultural drones reported to be in use there. Other middle-income countries have also been enthusiastic adopters. For instance, drones were used on 30% of Thailand’s farmland in 2023, up from almost none in 2019, mainly by spraying pesticides and spreading fertilizers.

In the U.S., the number of agricultural drones registered with the Federal Aviation Administration leaped from about 1,000 in January 2024 to around 5,500 in mid-2025. Industry reports suggest those numbers substantially underreport U.S. drone use because some owners seek to avoid the complex registration process. Agricultural drones in the U.S. are used mainly for spraying crops such as corn and soy, especially in areas that are difficult to reach with tractors or crop-dusting aircraft.

In countries such as China, Thailand and Vietnam, millions of smallholder farmers have upgraded from the dangerous and tiring job of applying agrochemicals by hand with backpack sprayers to using some of the most cutting-edge technology in the world, often using the same models that are popular in the U.S.”
