Ag Drone Services in Fond du Lac County, WI for Dairy Crops

Ag drone service rates in Fond du Lac County

Ag drone services in Fond du Lac County, WI are billed per acre, per pass, application only. Wisconsin drone rates for corn, soybeans, wheat and alfalfa run $11–22 per acre with $16 as the typical 2026 figure, and a northeast Wisconsin operator charges about $20 per acre on average-size fields. Our rates:

Service	Typical rate	Notes
Post-emerge herbicide	from $14/acre	Corn, soybeans
Alfalfa insecticide	from $14/acre	Weevil, potato leafhopper
Corn silage and grain fungicide	from $15/acre	Tar spot, leaf blights
Cover crop seeding	from $15/acre	After silage, into soybeans

Each visit has a $275 minimum. Dairy farms often book several fields at once, which keeps the per-acre cost low. Rates depend on acres per trip, field shape, wet ground, and the spray volume on the label.

One of Wisconsin's top dairy counties

Fond du Lac County ranked third in Wisconsin for farm sales in the 2022 Census of Agriculture, at about $612 million, and second in the state for milk sales at about $370 million. The county carries roughly 125,000 cattle, and livestock makes up 70% of sales.

Crop	2022 acres
Corn for grain	77,484
Soybeans	57,269
Forage (hay and haylage)	51,278
Corn silage	29,612
Wheat	15,818

With more than 80,000 acres in forage and silage, ag drone services in Fond du Lac County center on dairy feed as much as cash grain.

Fungicide on silage corn

On dairy farms, the most common drone job is fungicide on corn grown for silage, where leaf disease cuts both tonnage and feed quality. Tar spot has been in Wisconsin since 2016 and is now a regular concern in east-central counties, and UW–Madison names a single pass at tassel as the key timing. In soybeans, white mold fungicide works from R1 to R3. UW trials found drone fungicide at 2 gallons per acre performed like a 15-gallon ground pass on white mold, so dairies get protection without driving through tall corn.

Thin soils over Silurian bedrock

Fond du Lac is one of 16 Wisconsin counties with Silurian bedrock areas under the state's NR 151 performance standards. Where bedrock is within 2 feet of the surface, manure can't be applied; between 2 and 5 feet, bedrock depth must be verified and manure incorporated within set time limits. These thin soils over fractured dolomite let water and anything in it reach groundwater fast.

Drone application fits this ground:

• Low-volume, targeted passes with mapped no-spray zones over shallow-bedrock spots, wells and sinkholes.
• No wheel traffic on thin, rocky soils.
• Records of every application, alongside your nutrient management plan.

The Ledge, kettles and drumlins

The Niagara Escarpment, known locally as the Ledge, runs along the east side of the county near Oakfield, and the Northern Unit of the Kettle Moraine State Forest covers the southeast around Campbellsport. Fields here roll over kettles, drumlins and rocky rises.

Field condition	Ground sprayer	Spray drone
Kettle Moraine hills	Uneven boom, rollover risk	Follows terrain
Rocky ground below the Ledge	Equipment damage	No ground contact
Wet swales in spring	Ruts	Flies the same day
Tall silage corn	Crop damage	Flies above the canopy

Lake Winnebago, Horicon Marsh and buffers

The county wraps around the south end of Lake Winnebago, the Fond du Lac River runs into it, and the northern part of Horicon Marsh, including much of the national wildlife refuge, reaches into the county's southwest corner. Operators map shorelines, streams, ditches and wetlands as no-spray zones, use coarse droplets on edges facing water and check DriftWatch and BeeCheck for nearby specialty crops and hives.

Alfalfa, wheat and cover crops

Alfalfa weevil is treated before first cutting when tip feeding reaches threshold, and potato leafhopper on regrowth after the first and second cuttings. Wheat gets a fungicide at flowering to protect against head blight. After silage is chopped or wheat comes off, drones seed cereal rye or a cover mix at 5–30 pounds per acre the same week, covering bare ground before fall rains and giving dairies spring forage.

A Fond du Lac County spray season

Window	Typical drone work
Mid-May to early June	Alfalfa weevil before first cutting
June	Post-emerge herbicide in corn and soybeans
Late June to August	Potato leafhopper on alfalfa regrowth
Late July to mid-August	Fungicide on silage and grain corn at tassel, soybeans at R1–R3
Late August to October	Cereal rye after silage harvest, covers into standing soybeans

Spring planting around Fond du Lac usually runs from late April into May, and silage chopping starts in late August. Booking tassel-stage fungicide early matters most, since most dairies in the county want it on in the same two-week window.

Wisconsin licensing for drone application

The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) requires commercial drone applicators to certify in a base category such as 1.1 Field and Vegetable Crops plus the 9.9 Aerial Application category, and to hold an annual commercial applicator license and a Pesticide Business License. Product labels must allow aerial application. The FAA requires Part 107, a Part 137 certificate and a Section 44807 exemption for drones over 55 pounds.
