Ag Drone Spraying in Navarro County, Texas for Cotton and Corn

Ag drone spray pricing in Navarro County, TX

Ag drone spray work in Navarro County, TX is billed per treated acre for the application; defoliants, fungicides, insecticides and growth regulators are a separate line or come from your own supplier. These 2026 starting rates are for FAA Part 137-certified, state-licensed operators working the county's cotton, corn, wheat and pecan acres.

Service	Typical rate	Notes
Cotton insecticide or growth regulator	from $12/acre	Fleahoppers, plant bugs, mepiquat
Cotton harvest aid	from $13/acre	Defoliant and boll opener
Corn fungicide or insecticide	from $12/acre	Southern rust, stalk borers
Wheat fungicide	from $11/acre	Leaf and stripe rust
Pecan orchard pass	from $20/acre	Scab, casebearer; higher volume

What changes a quote: gallons per acre on the label, field size and shape, tree lines and power lines, and how many fields are booked in one trip. Most crews set a 30-acre minimum on row crops and a 10-acre minimum on pecans.

Row crops on Navarro County's blackland

West of the Trinity River bottoms, Navarro County sits on dark, heavy clay that grows corn near 17,000 acres, cotton above 11,000 acres and wheat around 5,000 acres. These clays shrink and crack when dry and turn sticky after rain, which is why a drone earns its place here:

• After a spring rain, clay fields stay too wet for a ground rig for days, right when corn and wheat need a timely pass.
• In a tall cotton canopy, a high-clearance rig still damages plants on turn rows; a drone does not touch the crop.
• On terraced and contoured fields, flight plans follow each terrace instead of overlapping across them.

The cotton season, pass by pass

Stage	Typical timing	Drone pass
Pinhead to first square	Late May–June	Fleahopper insecticide at threshold
Squaring to early bloom	June–July	Growth regulator to manage plant height
Bloom to cutout	July	Plant bug and stink bug control
Open bolls	August–September	Harvest aid: defoliant and boll opener

Harvest aid is where a drone helps most on Navarro County cotton. Defoliation has to be timed to boll maturity and weather, and cotton growers across the area want it at the same time. A crew that can fly a field the day after it is ready keeps harvest on schedule and fiber quality high.

Wheat and corn windows on Navarro County farms

Winter wheat in Navarro County is grazed by cattle on some farms and grown for grain on others. Grain fields get a fungicide pass when leaf or stripe rust shows up near flag leaf in March and April, and aphids are treated when counts reach threshold. Corn is planted early, often in late February or March, so its fungicide window falls in June, before the hottest weeks of summer. Southern rust and stalk borers are the most common reasons for a pass.

Because wheat fungicide, early cotton insect work and corn fungicide can all land within a few weeks of each other, growers who farm all three crops benefit from setting up a season plan with one crew. That way the drone is scheduled ahead of time instead of being called in after a field is already overdue.

Pecan orchards along the creeks

Navarro County has about 2,000 acres of orchards, mostly pecans on bottomland along Chambers Creek, Richland Creek and smaller creeks. Pecan scab in wet springs and pecan nut casebearer in late spring are the main reasons to spray. Drones can treat young and mid-size orchards and scab hot spots, especially when wet orchard floors stop air-blast sprayers. Large, mature trees often need high water volumes, so operators check whether drone coverage will be adequate before committing.

Richland-Chambers Reservoir, Navarro Mills Lake and creek bottoms

The county's southern edge borders Richland-Chambers Reservoir, and Navarro Mills Lake sits to the west. Many fields drain into creeks that feed these lakes. Operators map label setbacks around water, use coarser droplets when wind blows toward a lake or creek, and avoid flying products with aquatic restrictions near drainage ways.

Texas credentials for drone applicators

Before booking a crew for Navarro County fields, confirm that it holds:

1. FAA Part 137 agricultural aircraft operator certificate, Part 107 pilot certificates and a Section 44807 exemption for aircraft of 55 lb or more.
2. A Texas Department of Agriculture applicator license with Category 9 (aerial), paired with Category 1A (field crops) for cotton, corn and wheat.
3. Category 1B coverage when the job includes pecans or other nut and fruit crops.
4. Insurance and Texas-compliant records for every application.

The product label must also allow aerial application, and growers should check whether any county-specific herbicide rules apply to the product they plan to use.
