Crop Spraying in Freestone County, TX by Drone

Freestone County drone spraying rates

Crop spraying in Freestone County, TX is mostly grass work: bermuda and bahia hay meadows, improved pasture and the brushy edges around them. Drone crop spraying rates below are per acre, application only, from FAA Part 137-certified operators licensed by the Texas Department of Agriculture.

Service	Typical rate	Notes
Pasture broadleaf weed control	from $12/acre	Bitterweed, horsemint, ragweed, thistle
Hay meadow pre-emergent	from $14/acre	Sandbur and annual grass prevention
Armyworm or stem maggot insecticide	from $13/acre	Bermuda hay between cuttings
Smutgrass control	from $15/acre	Hexazinone in bermuda or bahia
Brush and briar spot spraying	from $17/acre	Dewberry, Macartney rose, regrowth
Peach and pecan orchards	from $19/acre	Higher spray volume, slower flight

Herbicide and insecticide are billed separately or supplied by you. The minimum charge is $300 per visit. Rates rise with brush density, higher gallons per acre, scattered trees, and distance from the operator's base. For comparison, Texas drone operators quote about $8–$21 per acre for standard field work and $15–$75 for brush, with $12 as the typical statewide figure, so these rates sit in the competitive middle for East Central Texas.

Freestone County is grass and cattle country

Freestone County sits between the Blackland Prairie and the East Texas Piney Woods, on sandy and clay-loam soils along I-45 between Dallas and Houston. Row crops are rare. The USDA 2022 Census of Agriculture counts 1,291 farms on 372,086 acres, averaging 288 acres, with $122.8 million in farm sales, of which crops made up only $6.7 million. Cattle carry the county: about 70,000 head in 2022, on roughly 340,000 acres of pastureland according to Texas A&M AgriLife Extension.

That profile shapes what drone spraying is used for here. Most jobs are pasture and hay weeds, hay insects and brush along fence lines and creeks, not corn or cotton. A growing season of about 263 days means two weed flushes, three to five hay cuttings and plenty of chances for armyworms.

When Freestone County pastures and hay get sprayed

Window	Target	Why then
Late February–March	Sandbur and annual grass pre-emergent in hay	Must be on before soil warms and seeds germinate
March–April	Winter and spring broadleaves: bitterweed, thistle, buttercup	Weeds are small and actively growing
May–June	Summer annuals: horsemint, ragweed, croton; smutgrass	Before seed set; adequate soil moisture
June–September	Fall armyworm and bermudagrass stem maggot	Regrowth after each cutting is most at risk
September–October	Fall broadleaf flush, brush regrowth	Plants moving sugars to roots carry herbicide down

Weed size decides the result

Pasture herbicides like 2,4-D, aminopyralid and triclopyr blends work best on weeds under 4–6 inches tall. A bitterweed or thistle rosette in March dies with a standard rate; the same plant flowering in May may only be burned back. The biggest advantage of drone crop spraying in Freestone County is getting on rough, wet or terraced pasture right on time, instead of waiting for the ground to firm up or for a crop-duster's schedule to open.

Drones apply 2–5 gallons of water per acre with RTK-guided swaths, so coverage is even across rolling ground without tire ruts in hay meadows that need to stay smooth for the swather and baler.

Smutgrass in bermuda and bahia

Smutgrass is one of the hardest pasture weeds in East Texas: cattle avoid it, it produces huge amounts of seed, and it spreads fast in overgrazed bahiagrass. Hexazinone is the main herbicide option, applied when soils are moist so rainfall carries it into the root zone. Because hexazinone moves with water, applications near ponds, creeks and the Trinity River bottoms need careful boundaries. Drone flight plans can exclude low wet areas and pond banks precisely, which is difficult with a ground boom.

Armyworms and stem maggots in hay

Freestone County bermuda hay, including Coastal, Tifton 85 and Jiggs, faces two summer pests:

• Fall armyworm. Texas A&M AgriLife suggests treating when you find about three or more half-inch caterpillars per square foot. Damage can strip a field in a few days, so speed matters more than anything.
• Bermudagrass stem maggot. Larvae kill the top leaves of regrowth, causing a frosted look and lost tonnage. Treatment targets adult flies about a week after cutting, with a follow-up 7–10 days later if pressure stays high.

A drone treats a fresh-cut meadow without driving over windrows or regrowth, and it can be on the field the day you call in a heavy count.

Briars, rose and brush along fence lines

Dewberry and blackberry thickets, Macartney rose, sweetgum and persimmon sprouts and post-oak regrowth creep in from fence rows and creek banks. Drones handle these as targeted spot treatments: the pilot maps patches from an overhead pass, then sprays only those polygons at a higher rate. That keeps herbicide costs down and protects shade trees you want to keep.

Peach orchards, reservoirs and drift

The Census lists about 1,600 acres of orchards in Freestone County, mostly peaches and pecans, along with vegetable plots and home gardens. These are highly sensitive to growth-regulator herbicides. Operators check wind direction relative to orchards, keep wind under about 10 mph, use coarse-droplet nozzles and avoid spraying in high heat that increases volatility. Fields near Richland-Chambers Reservoir, the Trinity River and stock tanks get label setbacks from water.

How a Freestone County pasture job comes together

1. Describe the property. Acreage, the main weeds or pests, the grass type (bermuda, bahia or native) and whether the field is grazed, cut for hay or both.
2. Pick the product. The operator matches the herbicide to the weed list and to your grazing and haying plans, and checks that the label allows aerial application.
3. Map the boundaries. Fields are outlined on satellite imagery, with ponds, homes, orchards and trees to protect drawn as no-spray zones.
4. Fly the job. On calm mornings a crew can treat a typical Freestone County hay meadow in a few hours, refilling from the trailer at the field edge.
5. Check results. Most broadleaf herbicides show full effect in two to four weeks; a follow-up look tells you whether a fall touch-up is needed.

Texas licensing for drone spraying

• FAA Part 107 remote pilot certificate and FAA Part 137 agricultural aircraft operator certificate, plus a Section 44807 exemption for drones over 55 lb.
• Texas Department of Agriculture commercial applicator license, which for drone work requires passing the General exam, the Aerial category and a second category matched to the job, usually Pasture and Rangeland (1C).
• Annual license renewal and continuing education credits, plus the insurance TDA requires for commercial applicators.

Ask for the TDA license number before booking. It can be checked against TDA's public license search in a couple of minutes.
