Drone Spraying in Marshall County, TN for Pasture, Hay and Row Crops

Drone spraying cost in Marshall County, TN

Drone spraying in Marshall County, TN is priced per acre for application only, with the herbicide, insecticide or seed billed on top. Operators serving the county work within the Tennessee range of about $9–17 per acre, and the most common 2026 rate in the state is around $12. Our starting rates sit near that middle:

Service	Typical rate	Notes
Pasture and hayfield herbicide	from $12/acre	Winter annuals, thistles, horsenettle
Hay insecticide	from $12/acre	Fall armyworm, grasshoppers
Corn or soybean fungicide	from $13/acre	VT–R1 corn, R3 soybeans
Clover overseeding	from $14/acre	Late winter into thin pastures
Brush and fencerow spot spraying	from $16/acre	Steep or rocky ground

The quote depends on acres flown per visit, the label's gallons per acre, terrain, trees and power lines, and travel. A $180 minimum per visit applies, so small horse pastures and hay lots are often grouped with neighbors' fields on the same day.

A livestock county first

Marshall County is grass country. The 2022 Census of Agriculture counted 995 farms on 144,148 acres, averaging 145 acres, with $85.5 million in sales, and livestock and products made up 87% of that total. The county had 31,166 head of cattle and 30,154 acres in hay and haylage.

Pasture covers 46,350 acres, woodland 33,620 acres and cropland 53,039 acres, a large share of which is hay. Row crops are smaller: roughly 6,700 acres of soybeans and 5,000 acres of corn. Four in ten farms are 10–49 acres, so most spray jobs here are hayfields, horse pastures and hillside grazing land rather than large grain fields.

Pasture and hay weed program by season

Pasture weeds in Middle Tennessee follow a predictable calendar, and University of Tennessee Extension guidance lines up with when drones are most useful.

Season	Target weeds	Why timing matters
November–March	Buttercup, henbit, chickweed, poison hemlock	Small winter annuals die easily; spray on days above about 60°F
April–May	Thistles in rosette or early bolt	Control drops sharply once flower stalks harden
June–July	Horsenettle, ironweed, pigweed	Treat before plants reach full height and set seed
August–September	Johnsongrass regrowth, brush resprouts	Plants move herbicide to roots in late summer

UT recommends the late-fall to early-winter window as the best time to control cool-season broadleaf weeds such as buttercup, before they flower and shade out spring grass. A drone covers that work on soft winter ground where a tractor would leave tracks across the whole field.

Fall armyworm in hayfields

Late-summer fall armyworm outbreaks can strip a bermudagrass or orchardgrass hayfield in a few days. UT Extension generally recommends treatment at about four larvae per square foot. Because treatment is often needed right after a cutting or on regrowth, a drone avoids driving over the stand, and it can reach steep corners that a boom sprayer skips.

Horse farms, glades and steep ground

Lewisburg is home to the Tennessee Walking Horse Breeders' and Exhibitors' Association, and horse farms are spread across the county. Those properties come with board fences, barns, run-in sheds and animals that dislike loud equipment.

Drones bring several advantages on that kind of ground:

1. Small, irregular paddocks are mapped exactly, and fences and barns are set as no-spray zones.
2. Horses can be moved to one paddock while the next is treated, with no tractor crossing gates.
3. Rocky cedar glade outcrops and steep hollows are covered without risking equipment.

Always check label grazing intervals for horses, which can differ from those for beef cattle, and tell the operator which paddocks hold mares and foals so those are scheduled last.

Working near the Duck River

The Duck River crosses Marshall County and is widely recognized as one of the most biologically diverse rivers in North America, especially for freshwater mussels and fish. Henry Horton State Park near Chapel Hill sits on its banks.

Fields along the river and its tributaries need careful planning: label buffers from water, wind limits that keep droplets on target, and flight paths that stay on private ground. A drone's low flight height and coarse droplet settings make that easier than with manned aircraft, but the operator still maps every setback before takeoff.

Corn and soybean passes

On the county's row-crop acres, the main drone jobs are corn fungicide at tassel for gray leaf spot and southern rust, soybean fungicide at R3, and stink bug control in late-planted beans. Late plantings after a wet spring are especially exposed to southern rust, and a drone can apply fungicide in corn that is far too tall for a ground rig.

Tennessee licensing for drone application

Every crew we connect you with is an FAA Part 137-certified, state-licensed operator. Federal rules require a Part 107 remote pilot certificate, a Part 137 certificate and a Section 44807 exemption for drones over 55 pounds. In Tennessee, the Department of Agriculture licenses for-hire aerial applicators: operators need commercial certification in the aerial category plus the agricultural crop category, an aerial (AER) license, proof of liability insurance and a decal for each aircraft. Tennessee also participates in FieldWatch, so operators check registered specialty crops and beehives before each job.
