Drone Spraying in Ottawa County, OK for Soybeans, Wheat and Hay

Ottawa County drone spraying prices

Drone spraying in Ottawa County, Oklahoma is billed per acre for application only. Product is charged at cost, or you supply it. Operators serving the county list $8–16 per acre for one pass, with a 2026 Oklahoma typical near $12. For comparison, OSU's 2021–22 custom rate survey puts statewide aerial liquid application at $10.20 per acre for herbicide, $7.53 for fungicide and $6.69 for insecticide, with East Oklahoma aerial herbicide averaging $8.16. Ground boom herbicide averaged $6.48 statewide, but ground rigs cannot run in flooded bottoms or tall soybeans without wheel damage.

Service	Typical rate
Soybean and corn herbicide	from $11/acre
Wheat fungicide (scab, rust)	from $12/acre
Soybean insecticide (stink bugs, podworm)	from $12/acre
Pasture and hay broadleaf, thistle	from $11/acre
Cover crop seeding	from $14/acre

Quotes depend on acres per trip, wet ground in the Neosho and Spring River bottoms, tree lines and wires, the gallons per acre on the label, and any tribal or trust-land paperwork. A $250 minimum applies per visit.

Ottawa County wheat scab and leaf diseases near Miami

On May 2, 2025, OSU reported Septoria nodorum blotch at Miami and noted that growers there were already spraying for Fusarium head blight. Rotating wheat behind corn raises scab risk because the fungus survives on corn residue. OSU puts the effective window at early flowering through five to seven days after. Spraying at heading misses it, and a pass costs about $30 per acre with product. Leaf rust and stripe rust were also found across the state that season. When spring rain floods bottom ground at flowering, a drone can still fly the pass on time.

Southern rust, leafhoppers and soybean insects

Southern rust. It was first confirmed in Oklahoma corn on July 14, 2025, in Caddo County. OSU finds fungicide pays from tassel (VT) to milk (R3) and not after dough (R4).

Corn leafhopper and corn stunt. In 2026 the leafhopper spread from Caddo County into north-central Oklahoma. Double-crop and late-planted corn after wheat carry the most risk. Foliar options include indoxacarb, flupyradifurone and thiamethoxam plus lambda-cyhalothrin. Skip non-ionic surfactant before tassel.

Soybean pod feeders. In northeast Oklahoma, corn earworm and green, southern green and brown stink bugs attack pods during set and fill. OSU thresholds:

• stink bugs, 1 per foot of row;
• earworm, 2 per foot;
• defoliation, 30% before bloom and 15% after.

Tar spot has not been confirmed in Oklahoma, though it has reached Kansas.

Ottawa County hay and pasture: thistle law

Hay and forage cover more acres than any crop in Ottawa County. Oklahoma law (2 O.S. §3-220) declares musk, Scotch and Canada thistle noxious statewide, and landowners must control them. Thistles are easiest to kill as rosettes in fall or early spring, before they bolt. A drone can treat rosettes across rough pasture and fence lines, or spot-spray scattered patches so less product goes on clover and forage.

Tar Creek, Grand Lake and flood ground

The Tar Creek Superfund Site covers the old Picher lead and zinc mining field, with chat piles and open shafts. Fields near it get extra care with wind and buffers, and pilots never land or load on chat. To the south, Pensacola Dam (1940) forms Grand Lake o' the Cherokees, run by the Grand River Dam Authority. In January 2024 FERC found that dam operations worsen upstream flooding around Miami and ordered GRDA to acquire flooded land. Miami's 2018 complaint cited 13,000 acres flooded repeatedly. Bottom ground along the Neosho and Spring rivers often stays wet into spray season, and a drone can treat it without rutting or getting stuck.

Tribal nations and trust land

Ottawa County hosts the headquarters of eight tribal nations: the Miami, Modoc, Ottawa, Peoria and Shawnee in Miami, the Quapaw in Quapaw, and the Wyandotte and Eastern Shawnee in Wyandotte. EPA's revised plan for restricted-use pesticide certification in Indian country, announced in October 2023, requires commercial applicators to hold an underlying state certification. A tribe can opt out, which generally bars restricted-use pesticides on its land. Trust and allotment land has its own rules. Operators confirm the land status and the tribal requirements with the landowner before treating.

ODAFF licensing, drift and airports

Oklahoma drone applicators need an ODAFF license with the Aerial (AIR) category, paired with a commercial category. New aerial applicants must include their FAA Part 137 certificate, list each aircraft and file a liability insurance certificate. Fees are $100 per category, capped at $500 a year. Pilots also hold Part 107 certificates, and drones over 55 pounds need a Section 44807 exemption. Oklahoma is not a FieldWatch state, unlike neighboring Kansas, Missouri and Arkansas. Operators contact neighbors, beekeepers and specialty growers directly and use medium or coarse droplets, since OSU warns that droplets under 150 microns drift easily. Miami Regional Airport (MIO), 2 miles northwest of Miami, is untowered.
