08 Spray drones have moved from experimental tools to serious application platforms across the United States, reshaping how growers think about coverage, timing, and field access. What began as a niche technology a decade ago has evolved into a fast‑growing segment of the precision‑ag market, driven by improvements in payload capacity, autonomy, and regulatory clarity. While Canada remains on the sidelines due to regulatory barriers, the US has become one of the most active spray‑drone markets in the world, with manufacturers, service providers, and growers rapidly expanding their use. Early Experiments and Commercial Adoption The earliest agricultural spray drones appeared in Asia in the early 2010s, where small field sizes and labor shortages made unmanned spraying attractive. These first‑generation platforms carried only a few liters of product and were used primarily in rice production. As battery technology improved and manufacturers began designing larger airframes, payloads increased to 20, 30, and eventually 40 liters (approximately 5.3, 7.9, and 10.6 gallons). By the late 2010s, US growers— particularly in specialty crops—began experimenting with drones for late‑season fungicide passes, wet fields, and steep terrain where ground rigs were less effective or more damaging. The turning point came when the US Federal Aviation Administration (FAA) formalized commercial drone rules under Part 107 in 2016. This created a pathway for agricultural operators to fly drones legally, and subsequent exemptions allowed for heavier aircraft, night operations, and multi‑ drone “swarming.” By 2022–2024, large‑format spray drones were entering commercial service across the Midwest, South, and Pacific Northwest. Today, drones are used in broadacre crops, orchards, vineyards, berries, and vegetables, complementing—not replacing—ground sprayers and manned aircraft. The Companies Behind the Technology The US spray‑drone market is shaped by a mix of global manufacturers and domestic innovators. DJI Agriculture, headquartered in Shenzhen, China, remains the most widely used brand, thanks to its Agras series, which includes the T40 and T20P. These drones combine high‑capacity tanks with dual‑atomized spraying systems and integrated mapping tools, making them accessible to both custom applicators and individual growers.
