Ag drone services rates in Sanilac County

Ag drone services in Sanilac County, MI are priced per acre for one pass, application only. Sanilac ranks first in Michigan for grains, oilseeds and dry beans, with $274.7 million in sales in 2022. Soybeans, corn, wheat and dry beans cover more than 327,000 acres between Sandusky, Marlette and the Lake Huron shore. Sugar beets for the Croswell factory add more. The rates below are set for that Thumb rotation.

Service	Typical rate	Notes
Soybean and corn herbicide	from $13/acre	Post-emerge, 2–3 gallons per acre
Dry bean white mold fungicide	from $14/acre	Bloom timing, closed rows
Wheat head scab fungicide	from $14/acre	Flowering, wet weeks
Corn tar spot fungicide	from $14/acre	Tassel to early grain fill
Cover crop seeding	from $15/acre	After wheat or into standing crops

Product is billed separately, or the grower supplies it. Michigan drone rates run about $11–21 per acre, with $15 typical for 2026, and local listings start at $13. Our rates sit at or under the state typical figure. The quote depends on water volume, crop height, field shape, wind turbines, wood lots and power lines, and travel distance. There is a 25-acre billing minimum per visit.

Drone fungicide for Sanilac County dry beans

Navy, black and other dry beans are a Thumb specialty, and Sanilac grows more than 34,000 acres of them. White mold is the main threat in wet summers. It infects through dead blossoms once the canopy closes, so the fungicide has to go on at early bloom, often with a second pass 7–14 days later. By then a ground rig crushes plants in narrow rows. A drone goes over the top without touching the crop. Anthracnose and bacterial blights also show up in wet years, and seed quality matters to elevators and canners, so clean pods are worth the pass.

Croswell sugar beets

The Michigan Sugar factory in Croswell was built in 1902 by the Sanilac Sugar Refining Company. It slices about 5,000 tons of beets a day and finished a six-year, $75 million upgrade in 2022. Cercospora leaf spot is the key beet disease, and strobilurin-resistant strains are common. Standard beet programs use high ground volumes. Drones are used only as a supplement: they hold the spray interval when fields are too wet to enter, and only where the label and the grower's Michigan Sugar agronomist agree.

Head scab, tar spot and white mold in grain

• Wheat: wet weather at flowering drives head scab and vomitoxin. A triazole at early flowering is the standard pass, and rain at that stage is exactly when ground rigs get stuck.
• Corn: tar spot has reached much of Michigan. Scout ear leaves from late July and plan a fungicide from tassel to early grain fill if lesions appear.
• Soybeans: white mold and frogeye leaf spot are scouted from R1, with R3 the usual fungicide timing after rows close.
• Dicamba: the 2026 over-the-top dicamba labels don't allow aerial application, so drone herbicide passes use other labeled post products.

Why ag drone services fit Thumb fields

• Heavy, flat ground: lake-plain clay in eastern Sanilac holds water after summer storms, and the drone treats it without ruts.
• No wheel tracks: narrow-row beans, closed soybeans and tasseled corn are treated without crop damage.
• Turbines and wires: wind farms such as Michigan Wind 2 put turbines in many fields. Operators map each tower and keep set distances.
• Small jobs: wet corners, waterways and spot weed patches are quick drone jobs.

Lake Huron shore and Black River water

Sanilac County's eastern edge runs along Lake Huron, from Lexington and Port Sanilac north toward Forestville. Fields along the bluffs drain straight to the lake, and the Black River drains much of the south of the county toward Port Huron. Tile outlets, county drains and stream banks get mapped as no-spray edges, with coarse droplets and wind blowing away from the water. Michigan is a FieldWatch state, so operators check DriftWatch and BeeCheck before every job, along with MDARD's Pesticide Notification Registry.

Local airports and airspace

Sandusky City Airport and Marlette Township Airport have no control towers. Most Sanilac County fields sit in uncontrolled airspace, but operators still check for crop dusters, medical helicopters and temporary flight restrictions before every flight. The area around Port Huron to the south sits closer to busier airspace.

MDARD licensing for drone applicators

Michigan's Department of Agriculture and Rural Development licenses drone applicators with the Core exam, the Aerial category and a crop category such as Field Crops. The aerial category needs three years and 200 hours of experience, or an MDARD-approved UAV training program. Businesses also need a Pesticide Applicator Business License. FAA requirements are Part 107, a Part 137 certificate, and a Section 44807 exemption for drones over 55 pounds.
