Ag Drone Spraying in Clark County, Wisconsin – Alfalfa, Corn & Soy

Ag drone spraying prices in Clark County

Ag drone spraying in Clark County, Wisconsin is priced per treated acre, application only, with the product or seed billed separately. Wisconsin operators typically quote $11 to $22 per acre for one pass, local starting rates begin around $10, and the most common rate in western Wisconsin is $16–$18. The starting rates below come from FAA Part 137-certified, state-licensed operators covering Neillsville, Greenwood, Loyal, Owen, Withee, Thorp and Granton.

Service	Typical rate	Notes
Alfalfa insecticide	from $14/acre	Leafhopper, weevil between cuttings
Corn & silage corn fungicide	from $14/acre	Tar spot, leaf blights
Soybean fungicide or insecticide	from $14/acre	White mold, aphids
Rye & triticale seeding	from $14/acre	Into standing crops or after silage
Frost seeding clover & alfalfa	from $14/acre	Late February–March

Price factors: total acres, label water volume, field shape, woods edges and wet spots, and travel between farms. Expect a minimum of about $350 per job; neighbors on the same road can be grouped to reach it. Blocks over 150 acres usually get a lower per-acre rate. Product and seed can come from your co-op or be sourced by the operator.

Wisconsin's top dairy county

Clark County sells more milk than any other county in Wisconsin, about $375 million a year according to the USDA 2022 Census of Agriculture. The county has 1,785 farms on 409,582 acres and nearly 149,000 cattle. Forage dominates the cropland: about 94,000 acres of hay and haylage and 40,000 acres of silage corn, alongside 72,540 acres of corn for grain and 58,007 acres of soybeans. Drone work here centers on keeping forage quality and yield high, from the first alfalfa cutting through fall cover crops.

Alfalfa program across cuttings

Timing	Target	Notes
Before first cutting, May	Alfalfa weevil	Scout tips in warm springs
After first cutting, June	Potato leafhopper	Regrowth is most vulnerable
After second cutting, July	Potato leafhopper	Hot, dry weeks raise pressure
After third cutting	Leafhopper, weeds	Late-season stand protection

Treating regrowth by drone means no wheel traffic on crowns and no compaction on hay ground, which is often wet in Clark County's heavy, poorly drained soils. Leafhopper-resistant varieties can raise the threshold, so scouting before each pass saves unneeded applications. UW–Madison Extension publishes alfalfa pest alerts during the season.

Corn, silage and soybeans

Tar spot has spread across central and western Wisconsin, and both grain and silage corn can need a fungicide at tassel to protect yield and feed quality. Soybeans get white mold fungicide at R1–R3 in cool, wet summers and aphid passes in August. A drone applies over tall canopies without track losses and works the day after a rain once wind and the label allow.

On dairy farms, silage corn is often the highest-value corn on the place, since every bushel of feed quality saved replaces purchased feed. Many Clark County dairies now scout silage fields for tar spot in mid-July and book a fungicide pass for the first week of tassel. Booking early in summer, before the whole region needs fungicide at once, helps secure a slot when it matters.

Heavy, wet soils

Much of Clark County's farmland is on heavy silt loam and clay soils that drain slowly. In wet springs and summers, ground sprayers either wait or cut ruts that cost yield for years. Drones keep passes on schedule without touching the soil, which matters most on hay ground and headlands that already see heavy traffic from choppers, wagons and manure spreaders.

How Clark County drone spraying works

1. Send field details: location, acres, crop, cutting or growth stage, and the target pest, disease or seeding job.
2. Mapping: the operator outlines each field and marks woods, wetlands, homes, barns and power lines.
3. Scheduling: a calm, rain-free window that fits the label and your cutting schedule is booked.
4. Application and record: RTK-guided passes are flown, and you receive treated acres, product, rate and weather data.

Rye and triticale for spring forage

Many Clark County dairies plant winter rye or triticale after corn silage for spring forage and to hold manure nutrients over winter. Drones can broadcast rye into standing corn or soybeans in late August and September, or onto silage stubble right after chopping when ground is too soft for a drill. Typical rates are 50–90 lbs per acre. In March, red clover or alfalfa can be frost seeded into thin hay stands. Records fit manure management plans and NRCS practices.

Black River, wetlands and woods

The Black River, Eau Claire River and many creeks, wetlands and woodlots cut through Clark County fields. Mapped no-spray buffers keep product off streams and wetlands, every water setback on the label is followed, and field edges along woods are treated with a safe set-back. Coarse droplets and low flight height reduce drift near farmsteads, calf barns and gardens. Fields next to wetlands are flown when wind blows away from the water.

Wisconsin licensing for drone application

Every operator holds an FAA Part 107 remote pilot certificate and a Part 137 agricultural aircraft operator certificate, plus a Section 44807 exemption for drones over 55 lbs. In Wisconsin, applying pesticides for hire requires commercial applicator certification and a pesticide application business license from the Department of Agriculture, Trade and Consumer Protection (DATCP). The UW–Madison Extension office in Neillsville offers applicator training and forage advice for Clark County farmers.
