Ag Drone Services in Kings County, CA

Ag drone service rates in Kings County, CA

Ag drone services in Kings County, CA are priced per acre, application only, by FAA Part 137-certified operators who hold California Department of Pesticide Regulation (DPR) credentials and are registered with the Kings County Agricultural Commissioner. Typical rates for fields around Hanford, Lemoore, Corcoran and Stratford:

Service	Typical rate	Notes
Corn silage and forage insecticide	from $16/acre	Spider mites, armyworms
Alfalfa insecticide	from $16/acre	Weevil, aphids, worms
Cotton insecticide or harvest aid	from $17/acre	Lygus, defoliation
Processing tomatoes and row crops	from $18/acre	Fungicide and worm passes
Pistachio and almond spot or block work	from $20/acre	Mites, hull-split timings
Walnut and dense orchard canopies	from $22/acre	Higher volume, slower flight

Product is billed separately or supplied by you. The minimum charge is $350 per visit. Tree crops cost more because of higher water volume and slower passes. California specialty-crop drone spraying commonly runs $18–$40 per acre, with field crops lower, so these rates sit at the competitive end for the valley.

Kings County farming: dairy, forage, cotton and nuts

Measure	Kings County

Top commodity	Milk, about $698 million

Livestock and crops split farm sales roughly evenly in Kings County. Dairies drive large acreages of corn silage, alfalfa and winter forage, while cotton, processing tomatoes, pistachios, almonds and walnuts round out the mix. That means agricultural drone services in Kings County are mostly field-scale forage and cotton work, with growing demand in nut orchards.

Corn silage and alfalfa for the dairies

Spider mites are the main summer threat in silage corn. UC IPM guidance focuses on early detection, with treatment decisions typically made while the corn is still roughly 2–4 feet tall, before mites move into the upper canopy. Once corn is tall, ground rigs struggle, and a drone can still fly over the canopy. In alfalfa, weevil larvae in spring and armyworms and aphids in summer need fast treatment between cuttings. A drone can treat a freshly cut field without driving over regrowth or irrigation borders.

Cotton: lygus and harvest aids

Kings County grows both Pima and Acala/upland cotton. Lygus bugs during squaring and early bloom are the key insect, and UC IPM recommends sweep-net sampling against established thresholds before treating. In September and October, defoliants and harvest aids are timed to boll opening. Drones are most useful on smaller fields, wet fields after irrigation and edges near dairies or homes where drift control matters most.

Pistachios, almonds and walnuts

Nut acreage has grown steadily in Kings County. Common drone jobs include mite spot treatments, hull-split navel orangeworm passes in a specific block, and canopy work after irrigation when the orchard floor is wet. For full-season programs in mature trees, airblast sprayers remain standard, and drones fill timing gaps and hard-to-reach blocks.

The Tulare Lake bed

Southern Kings County sits on the old Tulare Lake bed, a vast, flat basin with large fields, heavy clay soils and strong afternoon winds. In 2023 the lake returned and flooded more than 113,000 acres, the first time since 1997. Lake-bed fields can stay wet long after rain or flooding, and drones keep applications on schedule without rutting heavy clay. Wind is the main limit, so lake-bed work is usually flown in calm early-morning hours.

Groundwater limits and low-volume spraying

The Tulare Lake groundwater subbasin was the first in California placed on probation under the Sustainable Groundwater Management Act in 2024, adding fees and reporting for pumpers. Water is a real cost for many Kings County growers. Drones typically apply 2–5 gallons per acre rather than the 20–100 gallons of a ground or airblast sprayer, which reduces the water hauled and mixed for each job.

Processing tomatoes and winter forage

Processing tomatoes in Kings County face worm pests such as tomato fruitworm and beet armyworm in summer, plus powdery mildew late in the season. Many dairies also grow winter wheat, triticale or oat forage, which can need a broadleaf herbicide or an aphid pass in late winter when fields are too wet to drive after rain. A drone handles both: it flies over furrow-irrigated beds without damaging them, and it can reach winter forage fields during the short dry windows between storms.

Kings County spray calendar

Months	Main targets
February–March	Almond bloom fungicide; winter forage weeds
April–May	Alfalfa weevil; early mite checks in corn
June–July	Lygus in cotton; spider mites in silage corn; tomato worms
July–August	Hull-split navel orangeworm in almonds and pistachios
September–October	Cotton defoliation and harvest aids

NAS Lemoore, prisons and airspace

Naval Air Station Lemoore has controlled airspace that becomes active by notice, and operators check FAA airspace and NOTAMs before every flight near the base. Kings County also has state prisons near Corcoran and Avenal, and flying a drone over a prison is prohibited under California law. Operators plan routes to stay clear of these facilities.

California 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.
• California DPR: an Unmanned Pest Control Aircraft Pilot Certificate (Apprentice, then Journeyman) and a pest control business license.
• Kings County Agricultural Commissioner: annual registration of the business and pilots in the county, plus restricted materials permits and Notices of Intent where required.
• PCA recommendation: applications follow a written recommendation from a licensed pest control adviser.

Ask for the operator's DPR certificate and county registration before booking.
