Drone Spraying in Dane County, WI for Corn, Soybeans and Hay

Drone spraying rates in Dane County

Agricultural drone spraying in Dane County, WI is billed per acre, per pass, for the application only. Your fungicide, herbicide or seed is priced separately, whether you buy it from your co-op or the operator sources it. Wisconsin drone rates for 2026 cluster between $11 and $22 per acre for corn, soybeans, alfalfa and wheat, with $16 as the typical figure. Our listed rates sit just under that midpoint.

Service	Typical rate	Notes
Fungicide (corn, soybeans, wheat)	from $15/acre	2–3 gal/acre carrier
Herbicide (burndown, post-emerge, spot)	from $14/acre	Label must allow aerial use
Insecticide (aphids, weevil, leafhopper)	from $15/acre	Timed to scouting thresholds
Cover crop seeding	from $16/acre	Rye, oats, clover, brassicas
Liquid fertilizer / foliar feed	from $15/acre	Late-season N or micronutrients

The final quote depends on four things: total acres in one trip, the number of separate fields, obstacles (power lines, tree lines, farmsteads) and the gallons per acre your product label requires. Jobs under 20 acres carry a $250 minimum per visit, and fields more than 25 road miles from Madison may add a travel charge that is stated on the quote before anyone flies.

Agricultural drone spraying services available in Dane County

Dane County led Wisconsin in corn-for-grain production in 2023, with roughly 183,500 acres planted, and the 2022 Census of Agriculture counted 86,225 acres of soybeans and almost 54,000 acres of hay and haylage. Local FAA Part 137-certified, state-licensed operators fly these jobs:

• Fungicide passes on corn at VT–R2 and on soybeans at R1–R3, when a high-clearance sprayer would knock down rows.
• Post-emerge and spot herbicide for escaped waterhemp, giant ragweed and Canada thistle patches.
• Insecticide for soybean aphid, alfalfa weevil and potato leafhopper between hay cuttings.
• Cover crop seeding into standing corn and soybeans, or right behind the silage chopper.
• Foliar nutrients and late nitrogen on corn after canopy closure.
• Field mapping before the first flight, so boundaries, buffers and no-spray zones are loaded into the drone.

Tar spot and white mold: fungicide windows for Dane County fields

Disease pressure decides most summer flights in Dane County. UW–Madison Extension's 2026 updates flagged tar spot and southern rust in corn and white mold in soybeans as the diseases to watch, and red crown rot has been confirmed next door in Columbia County. Fungicides only pay when they are on the leaf inside a narrow window:

Crop	Main target	Application window
Corn	Tar spot, southern rust, gray leaf spot	VT/R1 through R3
Soybeans	White mold	R1 through R3 (little benefit after R4)
Winter wheat	Fusarium head blight, stripe rust	Flag leaf to early flowering
Oats	Crown rust	Flag leaf to heading

Tall corn at tassel and a closed soybean canopy are exactly when ground rigs do the most damage. A drone passes 8–12 feet above the crop, so there is no wheel-track loss, and work can continue on ground that is still too soft from a July storm.

Herbicide-resistant weeds in Dane County fields

Wisconsin waterhemp populations have tested resistant to Group 2 (ALS), Group 9 (glyphosate) and Group 14 (PPO) herbicides, and some show atrazine resistance. Giant ragweed is confirmed glyphosate-resistant in the state. That makes timing and layered residuals more important than ever:

1. Scout 2–3 weeks after planting, when waterhemp is under 4 inches tall.
2. Spray post-emerge with a different site of action than the pre-emerge, as listed on the product label.
3. Use spot treatment from the mapped weed patches later in the season to stop seed production along field edges and waterways.

Drone spot spraying lets you hit a 2-acre escape in the middle of a 120-acre field without paying to cover the whole field again.

Cover crop seeding after corn silage and soybeans

Dane County is dairy country: 125,000 cattle, about 26,000 acres of corn silage and milk sales near $270 million in the 2022 census. Silage ground comes off bare in early September, and that is the best window to establish a cover. Drone seeding spreads cereal rye, oats, clover or a brassica mix at 5–30 pounds per acre straight into standing soybeans at leaf drop or within days of chopping, without waiting for a drill. Earlier seeding gives a cover more fall growth to hold soil on rolling ground that drains to the Yahara lakes and the Sugar River.

Drone vs. ground rig vs. airplane on Dane County ground

Factor	Spray drone	High-clearance ground rig	Fixed-wing airplane
Compaction and crop damage	None	Wheel tracks, row damage late season	None
Wet fields after rain	Flies the same day	Waits for ground to firm up	Flies
Small or odd-shaped fields	Efficient	Slow turns, overlap	Costly minimums
Steep driftless slopes in the west	Follows terrain	Tip-over risk	Turns over hills
Drift control near homes	Low height, tight swath	Low	Higher risk

Western Dane County around Mount Horeb, Black Earth and Mazomanie sits in the Driftless Area, with steep slopes and narrow ridge-top fields. Eastern townships near Sun Prairie, Marshall and Cambridge are flatter but tile-drained and often wet in June. Drones handle both without changes to equipment.

Wisconsin licensing for drone pesticide application

Anyone applying pesticides by drone for hire in Wisconsin needs credentials from two agencies:

• FAA: Part 107 remote pilot certificate, a Part 137 agricultural aircraft operator certificate, and a Section 44807 exemption for drones over 55 pounds.
• Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP): an Individual Commercial Applicator license with a base category (such as Field and Vegetable Crops), the Aerial Application subcategory, and a Pesticide Business License for the company.

Every product must be labeled for aerial application; operators cannot raise the mix concentration beyond the label rate to save water. Ask your operator for their DATCP license number and certificate of insurance before the first flight.

Bees, specialty crops and neighbors

DATCP directs applicators to the voluntary FieldWatch registries: DriftWatch for specialty crops of half an acre or more, and BeeCheck for apiaries. Dane County operators check both before every job and flag organic farms, vegetable plots and hives within the drift zone. UW Machinery Extension also recommends notifying neighboring farms and businesses before flying, which is standard practice for crews working near Verona, Fitchburg and Middleton subdivisions.

How to get a Dane County drone spraying quote

1. Send your fields: a farm map, FSA field numbers or a pin on a map, plus crop and target pest.
2. Get a written quote: per-acre rate, product cost if supplied, travel and the planned flight window.
3. Flight and records: the operator flies, then sends an application record with date, product, rate, wind and acres covered.
