Otter Tail County agriculture at a glance

The 2022 USDA Census of Agriculture counts 2,497 farms on 770,922 acres in Otter Tail County, averaging 309 acres. Sales reached $551.3 million, 16th in Minnesota and up 58% from 2017, with crops making up 61%.

Crop	Acres (2022)
Corn for grain	173,119
Soybeans	159,496
Forage	73,435
Wheat	20,131
Dry edible beans	15,001

Vegetables, melons and potatoes rank third in Minnesota at $24.9 million, poultry and eggs sixth from about 880,000 turkeys, cattle tenth and milk twelfth. Prairie fields in the west and wooded, rolling lake country in the east are farmed very differently, and so is the spray work.

1,048 lakes and the buffer rules

Otter Tail County has 1,048 lakes, the most of any U.S. county, and about 11% of its area is water. The Otter Tail, Pelican, Leaf and Redeye rivers drain the fields, and the USFWS Fergus Falls Wetland Management District manages 216 waterfowl production areas totaling 44,499 acres across five counties. Minnesota's buffer law requires a 50-foot average (30-foot minimum) buffer on public waters and 16.5 feet on public drainage ditches. Pilots keep spray off those strips, avoid passes ahead of heavy rain and check FieldWatch for registered specialty crops and hives. Lakeshore cabins also need wide margins, since residents may be outside during the day.

Dry beans and soybeans: white mold

With 15,001 acres of dry edible beans, white mold timing matters in Otter Tail County. NDSU's guidance for pinto beans: when the canopy is at least 95% closed, spray at about 15% of plants with initial pods; when it is open, wait until about 50%. In soybeans, UMN finds fungicide works best at R1–R2, with a second pass at R3 in severe fields. Risk rises below 68°F with 10 or more days of moist soil and closing rows. Ground rigs damage closed bean canopies and struggle on wet soil, while a drone flies over both.

Soybean aphid and wheat scab

Soybean aphid. UMN treats at an average of 250 aphids per plant, with at least 80% of plants infested and numbers rising, through R5, and recommends acting within seven days. Pyrethroid resistance is widespread, so aphid-selective products such as Transform, Sefina and Sivanto are often the better choice.

Wheat scab. Fusarium head blight fungicide goes on at early flowering and up to seven days after; for barley, at full head emergence. Spring wheat flowers fast, so the window is short.

Waterhemp. UMN testing of 90 waterhemp populations from 47 counties found most resistant to Group 9 and Group 2. Another 31% resisted Group 14, 47% Group 5 and 22% Group 27. Post passes need layered modes of action on small weeds.

Irrigated sands around Perham

East Otter Tail has coarse, drought-prone sands, and the county holds 941 of Minnesota's 6,357 agricultural irrigation permits. Potatoes and vegetables grow under pivots there. In 2015, MDA tested 4,536 private wells across 32 vulnerable townships and found 4.1% at or above 10 mg/L nitrate. Parkers Prairie (17.9%), Compton (15.3%) and Perham (11.8%) townships ranked highest. On these soils, pilots stay well away from wellheads, never mix or rinse near wells, and coordinate passes with pivot schedules. NDSU has also reported late blight on tomatoes in Otter Tail County, a reminder to keep fungicide intervals tight on potatoes.

Dicamba 2026 and the I-94 line

Minnesota's 2026 dicamba restrictions use I-94 as the dividing line, and the interstate crosses Otter Tail County at Fergus Falls. Fields south of I-94 face a June 12 cutoff for over-the-top dicamba on tolerant soybeans, and fields north of it June 30. No application may be made when the field temperature or forecast high is above 85°F. The labels also require a 240-foot downwind buffer and prohibit aerial application, including drones. Dicamba stays with ground rigs, and the drone handles other modes of action. Check the MDA dicamba FAQ for how your field is classified.

Minnesota licensing and airports

Drone applicators in Minnesota need an MDA license with Category A (Core), Category B (General Aerial) and a site category such as C (Field Crops). Private applicators using restricted-use products by drone need a General Aerial endorsement. MnDOT requires drone registration and a commercial operation license backed by proof of insurance before an operator can advertise. Operators also hold FAA Part 107 and Part 137 certification, and drones over 55 pounds need a Section 44807 exemption. Fergus Falls Regional (FFM), 3 miles west of town, is untowered. Perham, Battle Lake, Henning and Pelican Rapids have smaller airports. Pilots check NOTAMs and local traffic before every job.
