Drone Spraying in DeWitt County, TX for Pasture, Brush and Hay

Drone spraying prices in DeWitt County

Drone spraying in DeWitt County, TX is quoted per acre, application only; herbicide and insecticide are billed separately or supplied by you. Texas A&M AgriLife's 2026 custom rate survey put aerial herbicide work in South Texas at an average of $11.72 per acre and aerial brush spraying at $13.43, and drone operators serving the county list rates from $12 to $15. Our pricing:

Service	Typical rate	Notes
Armyworm and grasshopper insecticide	from $11/acre	Bermuda and bahia hay
Pasture broadleaf weed control	from $12/acre	Croton, ragweed, broomweed
Hay field pre-emergent	from $13/acre	Grassbur on sandy ground
Mesquite and huisache brush	from $17/acre	Higher volume, slower flight
Pecan orchards	from $18/acre	Bottomland groves

Each visit carries a $300 minimum. Brush rates depend on tree density and height, the spray volume on the label, and how many well pads, lines and fences break up the pasture. Herbicide packages including product are available on request.

DeWitt County is pasture country

About three-quarters of DeWitt County farmland is pasture: 307,604 acres in the 2022 Census of Agriculture, alongside 22,230 acres of hay and only a few hundred acres each of corn and sorghum. Livestock brought in 90% of farm sales, and the county runs about 67,000 head of cattle. Cuero was also the starting point of the first Chisholm Trail drive in 1866, and cattle still drive the local economy.

For drone spraying in DeWitt County that means most jobs are on grass: keeping bermuda, bahia and native pastures productive, holding back brush, and protecting hay from weeds and armyworms.

Huisache, mesquite and brush control

Huisache spreads fast across Coastal Plain pastures and resprouts after shredding, so mowing alone rarely holds it. South Texas research on broadcast huisache treatments found fall applications of aminopyralid + clopyralid with picloram reached about 85% kill with good soil moisture, falling to about 71% under dry conditions; results improved after roughly 2 inches of rain in the two weeks before spraying.

Brush or weed	Typical approach	Timing
Huisache	Broadcast or individual-plant treatment	Fall, with soil moisture
Mesquite	Leaf spray on full-leafed, active trees	Late spring to early summer
Prickly pear	Herbicide labeled for pear, spot or broadcast	Per label, active growth
Macartney rose	Spot treatment along fences and draws	Active growth, full leaf

A drone can switch between broadcast and spot application on mapped coordinates, which saves product on pastures where brush is patchy rather than solid.

Hay meadow weeds and armyworms

Sandy loam hay fields in DeWitt County lose quality to grassbur (sandbur), and weedy hay sells for less. A pre-emergent pass in late winter, before grassbur germinates, keeps the first cutting clean. Summer passes take out croton, ragweed and broomweed while plants are small.

Fall armyworms show up on bermuda after late-summer rains. AgriLife sets the threshold at 2–3 larvae of half an inch or longer per square foot. A drone can treat a 40-acre meadow in about an hour, which is fast enough to stop the worms before they strip the field.

Flying around Eagle Ford pads, pipelines and lines

DeWitt County sits in the heart of the Eagle Ford Shale, and many pastures carry well pads, flowlines, tank batteries and overhead power lines. These are hard on ground rigs and dangerous for low-flying airplanes.

Obstacle	Ground rig	Ag airplane	Spray drone
Well pads and caliche roads	Drives around	Fly-over gaps	Mapped no-spray zones
Overhead power lines	Usually fine	Serious hazard	Mapped buffers
Pipeline right-of-way	Ruts on soft ground	Fine	No ground contact
Small pastures split by pads	Slow	High cost per acre	Efficient

Pecans and Guadalupe River bottoms

The county has about 1,060 acres of pecans, many in the Guadalupe River and creek bottoms around Cuero. These groves need fungicide for pecan scab in wet springs and insecticide timed to nut casebearer flights. Bottom ground stays soft after rain, and drones keep spray schedules on time without rutting the orchard floor. Tall, mature trees may still need ground airblast passes to cover the upper canopy, so many growers combine both.

Texas licensing for drone application

The Texas Department of Agriculture (TDA) licenses drone applicators. Commercial operators hold a TDA Commercial Applicator license ($200 per year) with three exams: the general exam, the Aerial Application category and a use category such as Pasture and Rangeland. Ranchers flying their own land can use a private applicator license with the aerial exam. The FAA requires Part 107, Part 137 and, for drones of 55 pounds or more, a Section 44807 exemption with a third-class medical.

DeWitt County is not on TDA's list of regulated-herbicide counties, so no extra county-level restrictions apply to 2,4-D-type products. Texas is a FieldWatch partner state, and operators check DriftWatch and BeeCheck for sensitive crops and hives before each job.
