Ag Drone Spraying in Howell County, MO for Pasture and Hay

Ag drone spraying rates in Howell County, MO

Ag drone spraying in Howell County, MO is almost all pasture and hay work on the Ozark Plateau around West Plains, Willow Springs and Mountain View. FAA Part 137-certified operators licensed by the Missouri Department of Agriculture typically charge these application-only rates:

Service	Typical rate	Notes
Fescue pasture broadleaf control	from $13/acre	Thistle, ragweed, buttercup
Hay meadow weed control	from $13/acre	After first cutting or before green-up
Fall armyworm insecticide	from $14/acre	Fescue and bermuda hay
Sericea lespedeza control	from $15/acre	June–September programs
Fescue renovation burndown	from $15/acre	Spray-smother-spray passes
Multiflora rose and brush spot spraying	from $18/acre	Rocky draws and fence rows

Product is billed separately or supplied by you. Jobs under 10 acres are billed as 10 acres. Rocky, steep or wooded ground and dense brush raise the per-acre price, as do long drives on gravel roads. Operators serving the county quote roughly $10–$30 per acre, and the Missouri drone average sits near $15.50, so standard pasture rates here are on the low side.

Howell County: cow-calf country on the Ozark Plateau

Howell County is Missouri's largest county by area and one of its top cattle counties. The USDA 2022 Census of Agriculture counts 1,392 farms on 363,963 acres, averaging 261 acres, with about 52,000 acres of harvested cropland, nearly all of it hay. Livestock makes up more than 90% of farm sales, and cattle sales rank among the highest in the state.

That makes agricultural drone spraying in Howell County a grass business. The main jobs are thistle and broadleaf control in fescue, sericea lespedeza on worn-out pastures, fall armyworm in hay, and brush along draws and fence lines. Rolling hills, chert rock and thin soils make many pastures hard on tractors and booms.

Sericea lespedeza: timing and product choice

Sericea lespedeza spreads quickly on low-fertility Ozark pastures. Cattle avoid it once it matures because of high tannin levels, and a single plant can produce hundreds of seeds. The Missouri Department of Conservation recommends spraying sericea from about June 1 through September 30, with triclopyr- or metsulfuron-based products. 2,4-D alone is not effective on this weed. Treating in early summer before bloom, then again in later years to clean up seedlings, gives the best long-term control. A drone can follow sericea patches across rocky slopes that are impossible to drive.

Renovating toxic fescue pastures

Kentucky-31 fescue infected with the toxic endophyte reduces weight gain and conception in cattle. University of Missouri Extension recommends a "spray-smother-spray" renovation: a glyphosate burndown in spring, a summer annual smother crop, then a second burndown in late summer before seeding a novel-endophyte fescue in fall. Drones handle both burndown passes on hilly fields and can work right after rain, when the fescue is actively growing and the timing is best.

Thistles, multiflora rose and Missouri's noxious weed law

Missouri law requires landowners to control listed noxious weeds, including musk thistle, Scotch thistle, Canada thistle and multiflora rose. In Howell County pastures:

1. Late March to April: thistle rosettes before bolting; buttercup in thin fescue.
2. May to June: multiflora rose in full leaf; ragweed and horsenettle in hay meadows.
3. September to October: a fall pass on new thistle rosettes.

Drone spot treatment of rose clumps and thistle patches uses far less product than broadcasting the whole pasture.

Springs, sinkholes and the Eleven Point River

Howell County sits on karst: sinkholes, losing streams and springs connect surface water directly to groundwater. The Eleven Point River, designated a National Wild and Scenic River in 1968, rises near Willow Springs, and the North Fork of the White River drains the west side of the county. Operators map sinkholes, springs, wells and creeks as no-spray zones, follow label buffers from water and use coarse-droplet nozzles. Missouri participates in FieldWatch, so crews also check the BeeCheck and DriftWatch registries before flying.

Why drones fit rocky Ozark ground

Challenge	Spray drone	Tractor and boom
Chert rock and steep slopes	Flies at constant height	Bounces, misses strips, rollover risk
Wet bottoms after spring rain	No ruts	Waits for ground to dry
Draws and fence rows	Spot and strip treatment	Hard to reach
Hay regrowth	No wheel damage	Drives over regrowth
Spray volume	2–5 gallons per acre	10–20 gallons per acre

On a typical 100–300 acre Howell County cattle farm, a drone can cover the whole place in one or two days, without hauling water across rough ground.

Fall armyworm in Howell County hay

Fall armyworms have hit southern Missouri hay and pasture hard in several recent years, usually from mid-August into September. Larvae feed at night and in early morning, and they can strip a freshly fertilized fescue or bermuda field in a few days. University of Missouri Extension suggests scouting field edges and low spots in the morning and treating when larvae are present in high numbers and still small. Larger larvae are harder to control and do most of the damage. A drone can be on a Howell County hay field within a couple of days of a call, treat it without running over regrowth and keep the next cutting on schedule.
