Drone fungicide on corn costs $12 to $18 per acre and is the single largest use case for agricultural drones in America, covering over 90 million acres annually. The critical application window is the VT to R1 (tassel) stage in July and August, when corn is too tall for ground rigs and the risk of trampling damage from tractor passes is highest. University trials from Beck's Hybrids and Iowa State Extension show drone-applied fungicide at 2 to 3 gallons per acre matches ground rig efficacy at 15 to 20 gallons per acre, with an average yield response of 5 to 8 bushels per acre.
Corn is the largest crop in the United States at over 90 million acres, and fungicide application at the VT/R1 (tassel) stage is the number one use case for drone spraying in America. Drones are the only practical option once corn exceeds 6–8 feet because ground rigs cannot clear the canopy. University research from Beck's Hybrids shows drone-applied fungicide at 2–3 gpa matches ground rig results at 15–20 gpa, with no yield loss from trampling.
Drone application can respond quickly to any of these threats, even in fields with difficult access.
Green = optimal application window

The typical rate for drone spraying on corn is $12–$18 per acre for application only — the farmer supplies the chemical product. Pricing varies based on total acreage, distance from the operator's base, and product type. Larger fields (500+ acres) often qualify for lower per-acre rates.
Optimal timing for drone applications on corn is: Jul, Aug. Applications should be made at low wind speeds (under 10 mph), ideally early morning or evening, to maximize product adhesion and minimize drift.
Key advantages of drone application over ground equipment: (1) zero soil compaction, (2) can operate when fields are too wet for tractors, (3) high-precision GPS coverage with 95%+ uniformity, (4) can treat irregular or small fragmented fields, and (5) can spray tall crops like corn at full canopy. The main trade-off is a smaller tank size compared to pull-behind ground rigs.
