Turkey barns and biosecurity

Willmar is home to Jennie-O and the Minnesota Poultry Testing Laboratory, and Minnesota has led the nation in turkeys since 1959. H5N1 avian influenza hit a Kandiyohi County flock of 30,400 birds in fall 2025. The Board of Animal Health asks visitors to minimize farm traffic, clean and disinfect vehicles, and use disposable boots and coveralls. Spray crews stay out of barn areas, park away from poultry sites and follow each farm's biosecurity rules.

Soybean aphid

University of Minnesota's threshold is an average of 250 aphids per plant with more than 80% of plants infested and numbers rising, through R5. UMN advises scouting weekly from mid-to-late June until R6.5. A drone treats full-canopy soybeans without driving down rows.

White mold

White mold damages some Minnesota soybean fields nearly every year. It is favored by flowering, closing rows, ten or more days of moist soil and temperatures below 68°F, and manure history raises the risk. UMN says fungicide works best at R1–R2, with a second pass at R3 in severe fields.

Waterhemp resistance

UMN tested 90 waterhemp populations from 47 Minnesota counties between 2021 and 2023. Most resisted group 9 and group 2 herbicides, 47% resisted group 5, 31% group 14, 22% group 27 and 10% 2,4-D, and two populations resisted six groups. UMN advises full rates before weeds reach 4 inches. Drones help with rescue passes where the label allows aerial use.

Tar spot spreading

UMN's 2025 season review found tar spot spreading across Minnesota and nearby states, with white mold widespread as well. Corn fungicide decisions are made from scouting around tassel to early grain fill.

Lakes, wetlands and the buffer law

Kandiyohi County has nearly 70 named lakes, including Green Lake near Spicer at 5,560 acres, plus Sibley State Park with Mount Tom and several wildlife management areas. Minnesota's buffer law requires an average 50-foot buffer (30-foot minimum) on public waters and 16.5 feet on public ditches. Operators map lakes, wetlands, buffers and homes as no-spray zones and check DriftWatch and BeeCheck before every job.

Registries and bee-kill compensation

Minnesota runs DriftWatch, BeeCheck and FieldCheck with the MDA. Sensitive sites of half an acre or more can register, and registrations must be renewed every year. Beekeepers who want to qualify for state bee-kill compensation must register hives in BeeCheck, which gives operators a current map of apiaries before every flight. Kandiyohi County also ranks second in Minnesota for aquaculture, so ponds and fish operations are mapped alongside lakes and wetlands.

Field conditions

Field condition	Ground sprayer	Spray drone
Wet ground around potholes	Ruts, stuck rigs	No soil contact
Corn at tassel	Crop damage	Flies above the canopy
Soybeans at R3	Wheel-track losses	No crop contact
Fields near turkey barns	Biosecurity risk	Stays outside barn areas

Minnesota licensing

The Minnesota Department of Agriculture (MDA) requires commercial drone applicators to hold Category A (Core), Category B (General Aerial) and a site category such as C (Field Crops). Minnesota also requires drones to be registered with MnDOT, and a MnDOT commercial operations license with proof of insurance before advertising spraying for hire. Willmar's airport sits two miles west of town without a tower, so operators check airspace nearby.
