Drone Spraying in Pittsburg County, OK for Pasture, Hay and Brush

Drone spray prices for Pittsburg County pasture and hay

Drone spraying in Pittsburg County, OK is priced per acre for one pass, application only. Livestock brings in 93% of farm sales here, and pasture covers about 264,000 acres. So the rate table is built for grazing land, hay meadows and brushy draws, not for wheat and cotton.

Service	Typical rate	Notes
Pasture broadleaf herbicide	from $11/acre	Ragweed, thistle and summer annual weeds
Hay meadow weed control	from $11/acre	Bermudagrass and native hay
Sericea lespedeza program	from $12/acre	June–July or September timing
Fall armyworm insecticide	from $11/acre	Hay and pasture, treated the day it's scouted
Brush and woody spot spraying	from $18/acre	Higher volume, slower passes in timber edges

Product is billed separately, or the rancher supplies it. Oklahoma drone rates run about $8–22 per acre, and most quotes land at $12–15. For comparison, OSU's custom rate survey puts manned aerial herbicide in eastern Oklahoma at about $9 per acre, but airplanes rarely take small, wooded tracts. The quote depends on water volume, timber edges and draws, field shape, power lines and travel distance. There is a 25-acre billing minimum per visit.

Pittsburg County ranch country in numbers

Measure	Pittsburg County, OK (2022 Census)
Farms / land in farms	1,412 farms / 475,795 acres
Average farm size	337 acres
Market value of sales	$44.6M, 56th in Oklahoma
Livestock share of sales	93%
Cattle and calves	72,369 head, $38.4M in sales
Pasture / woodland / cropland	264,062 / 118,096 / 80,183 acres
Hay and forage	55,591 acres

More than half of farmland is pasture and a quarter is woodland. Grass quality decides calf weights, and most spray work is weed and brush control on grazing land. Row-crop passes are a small share here.

Why drone spraying fits Pittsburg County terrain

The county is hilly to mountainous, and the Ouachita foothills reach into the southeast. Pastures are cut by wooded draws, ponds and creek bottoms that drain south toward the Kiamichi River. That ground causes trouble for every other method:

• Ground rigs bog down in creek bottoms after rain and can't safely cross steep side slopes or rocky draws.
• Airplanes need long, open fields. A 60-acre pasture wrapped in post oak and blackjack timber is hard to treat from airplane height without drift into the trees.
• Drones fly 8–15 feet above the grass, follow the terrain, and can treat only the mapped weed patches instead of the whole pasture.

Spot spraying matters on rangeland, because broadcast treatment of a lightly infested pasture often costs more than the grass it saves.

Sericea lespedeza timing in eastern Oklahoma

OSU Extension rates sericea lespedeza as a bigger problem in eastern Oklahoma, where rainfall tops 30 inches a year. Herbicide choice depends on the calendar:

1. May to early June: Cimarron Max on young plants.
2. June to early July: Remedy at 1 pint per acre or PastureGard at 1.5 pints per acre.
3. September, at mid-bloom: Cimarron at 0.5 ounce per acre.

OSU reports poor control from 2,4-D, Grazon P+D and Weedmaster. Because the seed bank lasts for years, a field needs a follow-up pass the next season. Mapping each infested patch with the drone makes that second-year pass cheaper.

Oklahoma's thistle law and pasture weeds

Under 2 O.S. §3-220, musk, Scotch and Canada thistle are noxious weeds in every Oklahoma county. Landowners must control them every year before they set seed, and fines can reach $1,000 per violation per day. Thistles grow as rosettes through winter, and a spring herbicide pass before bolting is the most reliable timing. Scattered thistle patches are where spot-mode drone work saves the most product.

Fall armyworm in Pittsburg County hay

In July 2025, OSU Extension reported fall armyworm already above control thresholds in Pittsburg County pastures and hayfields. The OSU threshold for pasture and hay is three to four half-inch larvae per square foot. Count them at the half-inch stage, when larvae are easiest to kill. Moths keep laying eggs until a killing frost, so one flight seldom ends the season. A drone can treat a hay meadow the same morning it's scouted, without tracking regrowth that's about to be cut.

Eastern redcedar encroachment

Eastern redcedar is spreading across Oklahoma at about 762 acres a day, and roughly 8 million acres in the state carry 50 or more trees per acre. Mechanical removal runs $25–100 per acre. Conservation districts and NRCS may offer cost-share. Oklahoma has been field-testing drones that drop herbicide pellets at individual trees, at an estimated $1–3 per tree. Small cedars under a few feet are the cheapest to deal with. Mapping them by drone before they close the canopy keeps future costs down.

Where drones don't fit: native pecans

Pittsburg County has about 347 acres of pecans. For pecan weevil, which peaks from late August to mid-September, OSU recommends airblast sprayers at 100 gallons per acre or more to reach the top of mature trees. A spray drone can't deliver that volume. Operators here will usually recommend ground equipment for pecan insect work and use the drone for weeds under young trees and on grove edges.

Lake Eufaula, creeks and drift control

Lake Eufaula covers about 102,000 acres with some 600 miles of shoreline. It is Oklahoma's largest lake by volume and forms much of the county's northern edge along the Canadian River. Brushy-Peaceable Creek reservoir near Savanna and Kiowa, Gaines Creek and dozens of stock ponds sit beside grazing land. Spraying near water follows label setbacks and aquatic-use restrictions.

Oklahoma is not a FieldWatch state, so there is no statewide registry for neighbors' gardens, vineyards or beehives. Operators ask landowners about nearby sensitive sites and check the Oklahoma Mesonet Drift Risk Advisor, a 48-hour forecast of drift-prone wind and temperature conditions. OSU recommends medium or coarse droplets, because droplets under 150 microns drift easily.

McAlester airspace, the ammunition plant and tribal land

• McAlester Army Ammunition Plant covers about 44,964 acres southwest of town. Operators treat it as a military installation and check FAA restrictions before flying fields near its fence line.
• McAlester Regional Airport sits about 3 miles southwest of the city, with a 5,602-foot runway. Fields near the approach need airport awareness.
• Choctaw Nation: Pittsburg County lies within the Choctaw Nation reservation. On tribal trust or allotted land, operators confirm which rules apply before scheduling the job.

ODAFF licensing and insurance for drone applicators

The Oklahoma Department of Agriculture, Food and Forestry licenses aerial applicators. A for-hire drone operator holds a commercial license with the AIR aerial category, paired with a use category such as 1A Agricultural Plant or 6 Right-of-Way. Fees are $100 per category. New aerial applicants submit an FAA Part 137 certificate, and drones over 55 pounds also need a Section 44807 exemption.

Aerial applicators must carry at least $100,000 bodily injury per person, $300,000 per occurrence and $100,000 property damage, and the policy must cover drift. Pittsburg County is not one of Oklahoma's restricted-herbicide counties, which are limited to Greer, Harmon, Kiowa, Jackson and Tillman in the southwest.
