Ag Drone Services in Kittitas County, WA for Timothy Hay & Pasture

Ag drone service rates in Kittitas County

Ag drone services in Kittitas County, WA center on the Ellensburg valley's timothy and alfalfa hay, irrigated pasture and the noxious weeds that creep in from field edges and canal banks. Rates below are per acre, application only, from FAA Part 137-certified operators licensed by the Washington State Department of Agriculture (WSDA).

Service	Typical rate	Notes
Timothy and grass hay broadleaf control	from $16/acre	Before green-up or between cuttings
Alfalfa insecticide	from $16/acre	Weevil, aphids
Irrigated pasture weed control	from $16/acre	Thistle, dock, buttercup
Noxious weed spot spraying	from $17/acre	Knapweed, whitetop, toadflax
Cover crop and pasture seeding	from $17/acre	Reseeding thin stands
Grain fungicide	from $18/acre	Wheat and barley at heading

Product is billed separately or supplied by you. The minimum charge is $250 per visit. Washington drone operators typically charge about $14–$22 per acre, with $17 as the statewide typical rate, so these rates sit in the middle of the state market. Windy days, steep foothill ground and scattered noxious weed patches can raise the per-acre cost.

Kittitas County is hay country

The USDA 2022 Census of Agriculture counts 738 farms on 165,205 acres in Kittitas County, averaging 224 acres, with about 39,600 acres of harvested cropland. Most of that cropland is hay and forage, and timothy is the county's largest cash crop. Much of it is pressed and shipped as premium export hay to buyers in Asia and the Middle East.

Export timothy must be clean and weed-free to make top grade, so agricultural drone services in Kittitas County focus heavily on hay quality: broadleaf control before green-up and between cuttings, insect control in alfalfa and spot treatment of noxious weeds before they reach the hay.

Weed control for export-grade timothy

Dandelion, dock, buttercup, thistles and mustards lower the grade of timothy hay, and grassy weeds are hard to remove once a stand is established. Most broadleaf work happens in early spring before green-up or soon after, when weeds are small and the timothy is not yet tall. Some products have long waiting periods before cutting, so the spray date and herbicide must match your first-cut schedule. A drone avoids ruts in irrigated fields and treats only the weedy portions when patches are mapped first.

Alfalfa weevil, aphids and grasshoppers

Alfalfa weevil larvae feed on new growth in spring, and Washington State University suggests treatment based on sweep-net counts before first cutting. Aphids and, in dry years, grasshoppers moving in from rangeland can damage regrowth later in summer. A drone treats fresh-cut regrowth without driving over it and reaches corners and canal edges a ground rig misses.

Noxious weeds and the county weed board

The Kittitas County Noxious Weed Control Board enforces control of listed weeds, and landowners are responsible for weeds on their property. Common problems in the valley include diffuse and spotted knapweed, whitetop, Dalmatian toadflax, perennial pepperweed and Canada thistle. Drones are well suited to these jobs: an aerial scan finds patches along ditches, roads and pasture edges, and the drone spot-treats them without spraying the whole field.

Wind: the valley's biggest spraying challenge

Ellensburg is one of the windiest places in Washington, and the Bowers Field weather station records some of the highest average wind speeds in the state. Wind farms along the ridges are a reminder of how often it blows. Drone crews plan for this: flights start at first light when air is calmest, coarse-droplet nozzles are used, and work stops when wind exceeds label limits. Because a drone can launch quickly from the field edge, it can take advantage of short calm windows that a larger operation would miss.

Irrigation canals and the Yakima River

The valley is irrigated by an extensive canal system, including the Kittitas Reclamation District's network serving about 60,000 acres, and drains to the Yakima River, which supports salmon and steelhead. Operators keep spray out of canals, laterals and creeks, follow label buffers for water and endangered species protections, and map no-spray zones along every ditch. Washington is a FieldWatch state, so crews also check the registry for nearby specialty crops and beehives.

Foothill pastures and small acreages

Outside the irrigated valley floor, Kittitas County has foothill grazing land, horse properties and small acreages around Cle Elum, Thorp and the Manastash and Badger Pocket areas. These tracts often have cheatgrass, knapweed and thistle on steep or rocky ground where a tractor is unsafe. A drone treats these slopes at a constant height and spot-sprays scattered weed patches, and several nearby small properties in Kittitas County can be grouped into one trip to keep travel costs down.

Airspace near Ellensburg

Bowers Field in Ellensburg and the Yakima Training Center restricted airspace in the southeast corner of the county affect where and when drones can fly. Operators check FAA airspace data for every field and avoid restricted areas when they are active.

Washington licensing for drone spraying

• FAA: Part 107 remote pilot certificate, Part 137 agricultural aircraft operator certificate and a Section 44807 exemption for drones over 55 lb.
• WSDA: a commercial pesticide applicator license with the aerial category that covers drone application, plus the appropriate crop categories. WSDA also licenses the application equipment used by commercial applicators.
• Records: application records kept for every job and available to the landowner.

Ask for the operator's WSDA license number before booking.
