Crop Spraying in Yakima County, Washington

Crop spraying rates in Yakima County

Crop spraying by drone in Yakima County, WA is priced per acre for one pass, application only. You buy the product through your fieldman or farm supply, and a WSDA-licensed operator applies it at label rate.

Service	Typical rate	Notes
Hop yard fungicide & miticide	from $22/acre	powdery mildew, spider mites
Vineyard fungicide	from $20/acre	powdery mildew, higher water volume
Young orchard & block-edge passes	from $22/acre	apples, cherries, pears
Alfalfa & timothy hay	from $14/acre	weevil, aphids, weeds
Wheat & corn passes	from $14/acre	rust, aphids, fungicide

Washington drone spraying typically runs $14–$22 per acre for field crops and $18–$32 for orchards, and a Yakima-based operator lists $15–$30. Our starting rates sit near the lower middle of those ranges. Price depends on acres, water volume, trellis height, canopy size, wind machines, power lines, homes and travel from Yakima or Sunnyside. Small blocks are billed at a 10-acre minimum.

Farming in the Yakima Valley

Yakima County is one of the most diverse farm counties in the country, from the Naches and Tieton valleys in the west to the Lower Valley around Sunnyside and Grandview. The USDA 2022 Census counts 2,523 farms on about 1.79 million acres, averaging 711 acres, much of it rangeland. Orchards cover about 87,300 acres, alfalfa and hay about 26,800, wheat about 24,000 and corn about 15,800. The valley also grows most of the country's hops, plus wine and juice grapes, and has large dairy and cattle operations.

Crop	Common targets	Typical drone window
Hops	Powdery mildew, downy mildew, two-spotted spider mite	May–August
Wine & juice grapes	Powdery mildew, leafhoppers	May–August
Apples, cherries & pears	Codling moth, cherry fruit fly, pear psylla	April–September
Alfalfa & timothy	Alfalfa weevil, aphids, weeds	April–August
Rangeland	Diffuse and spotted knapweed, rush skeletonweed	Spring and fall

Yakima County hop yards from Moxee to Toppenish

Hops grow on trellises about 18 feet high around Moxee, Toppenish, Wapato, Granger and Mabton. Disease and mites build fast in summer, and spray rigs must drive every alley. Drones help hop growers:

• Powdery mildew fungicide on a tight schedule through the season.
• Spider mite passes on hot spots before they spread.
• Top-of-canopy coverage where ground air-blast sprayers reach less well.
• Wet alleys after irrigation treated without ruts.

Vineyards in Rattlesnake Hills and Yakima Valley

Wine grapes in the Rattlesnake Hills, Zillah and Prosser-area slopes, and Concord juice grapes in the Lower Valley, need regular powdery mildew sprays from bloom through veraison. Drones cover sloped blocks and narrow rows quickly, and they're useful for edge rows and wet spots. Large canopies and late-season sprays still often go on with ground equipment.

Orchards: where drones fit

Apples, cherries and pears dominate the upper valley around Naches, Tieton, Selah and Cowiche. Mature trees with dense canopies usually need high-volume air-blast sprayers for full coverage. Drones work best on young blocks, high-density trellised plantings, block edges and hard-to-reach slopes, and for herbicide strips and cover crops between rows. Operators check each label for aerial use and recommend the right method for each block.

Alfalfa, timothy and dairy feed in Yakima County

Lower Valley dairies around Sunnyside, Grandview and Outlook depend on alfalfa and silage corn, and timothy hay is grown for export. Alfalfa weevil hits the first cutting and aphids follow. Drones spray between cuttings without driving on regrowth, and operators check harvest intervals on each label.

Rangeland weeds and canal banks

Much of the county is shrub-steppe rangeland where knapweed, rush skeletonweed and other noxious weeds spread along roads and canal banks. Drones reach steep hillsides and long ditch banks, and they work for spot treatment of weed patches on large ranches.

Canals, the Yakima River and restricted airspace

Irrigation canals such as the Roza and Sunnyside carry water across the valley, and the Yakima and Naches rivers support protected salmon and steelhead. Labels require buffers from water, and some products have extra stream buffers. Drones hold mapped buffers precisely. The Yakima Training Center's restricted airspace lies to the northeast, and Yakima Air Terminal controls airspace near the city, so operators plan routes and authorizations around both.

Work on the Yakama Reservation

A large part of the county lies within the Yakama Nation reservation, including farmland around Toppenish, Wapato and White Swan. Pesticide applications there can follow tribal and federal rules in addition to state licensing, so operators confirm the requirements before each job.

Spray calendar for Yakima County

Why Yakima County growers use drones

• Tall hop trellises and sloped vineyard blocks.
• No ruts in irrigated alleys and fields.
• Precise buffers around canals, rivers and homes.
• Spot treatment on rangeland and canal banks.
• Fast response during mildew and mite outbreaks.

Washington licensing for drone spraying

The Washington State Department of Agriculture (WSDA) licenses pesticide applicators. Anyone spraying for hire by drone needs a commercial applicator license with the aerial category, and aerial application equipment must also be licensed with WSDA. Growers spraying their own land with restricted-use products need a private applicator license.

Federal rules require an FAA Part 107 remote pilot certificate, a Part 137 agricultural aircraft operator certificate and a Section 44807 exemption for drones over 55 pounds. If a label prohibits aerial application, the product cannot be applied by drone.
