Snohomish County leads Washington in nursery and greenhouse sales. Dairy, berries, pumpkins and vegetables for farm stands round out a farm economy squeezed between fast-growing cities. Layers are a big part of it too, with about 800,000 hens on Snohomish County farms in 2022. Many farms are run part-time, and owners rent small fields scattered across the valley. A drone crew can treat several of those fields in one day without moving a sprayer down busy roads like Highway 9 and Highway 2.

Crop spraying on Snohomish County floodplain farms

Much of the county's commercial farmland lies in river floodplains, behind dikes and drained by ditches and tide gates. The local Agriculture Resilience Plan counts over 63,000 acres of active farmland and expects more frequent flooding. It also warns that spring field access in the estuaries could be delayed by up to three weeks by the 2050s. Saltwater is already reaching crops in patches on Florence Island in the Stillaguamish estuary, near Stanwood. Organic soils in some areas may be sinking 2–3 inches per decade.

Wet ground is the biggest limit on spraying in the valley. A drone can treat a field the day after rain, when a tractor would rut soft valley soil, and it doesn't need to cross ditches or dike roads.

Dairy forage and silage corn

Milk is the county's second-largest farm product. Grass hay and silage corn feed dairies in the Snohomish valley and around Arlington and Stanwood. Common jobs include broadleaf weed control in grass fields such as buttercup and thistle, herbicide passes in young corn, and late-summer cover crop seeding into silage corn so the soil is covered before winter rain. Grazing and haying intervals depend on the product and go on every record. Manure is spread on much of this ground, so operators also note any recent applications and nearby lagoons when mapping a field.

Berries, pumpkins and nursery stock

• Blueberries and raspberries: about 1,900 acres of berries. Mummy berry, botrytis and spotted-wing drosophila drive most passes, often close to harvest.
• Pumpkins and vegetables: farm-stand crops in the Snohomish valley face powdery mildew and aphids in late summer.
• Nursery stock: about 2,100 acres. Field-grown trees and shrubs get weed control and spot passes where the label allows aerial use.

Many of these farms host visitors in fall, so operators time flights for early morning and keep spray away from parking and public areas. Corn mazes, pumpkin patches and u-pick fields bring thousands of people into the valley every October, and some fields are planned around those weekends.

Salmon rivers and tribal lands

The Snohomish, Skykomish, Snoqualmie and Stillaguamish rivers carry salmon, and farmland borders them on every side. The county's Sustainable Lands Strategy has worked since 2010 to balance fish, farm and flood needs. In Snohomish County, operators map sloughs, ditches and riverbanks as no-spray edges, use coarse droplets near water, and avoid flights before heavy rain. The Tulalip Tribes and the Stillaguamish Tribe have treaty rights and lands in the area, and operators confirm whether any fields fall under tribal rules.

Paine Field and Seattle airspace

Paine Field in Everett has a control tower, a Boeing factory and busy passenger and freight traffic, and Seattle's Class B airspace reaches into the south county. Arlington Municipal and Harvey Field near Snohomish have no towers, but small planes and skydivers use them heavily. Fields near Everett, Mukilteo and Snohomish may need FAA authorization, and operators check traffic and notices carefully before every single flight.

Washington licensing for drone applicators

For-hire drone applicators in Washington need a commercial applicator license from the Washington State Department of Agriculture with the aerial category and the right crop categories. FAA requirements are Part 107, a Part 137 certificate, and a Section 44807 exemption for drones over 55 pounds.
