Hein Ranch Co. (FlyingAg)

Hein Ranch Co. (FlyingAg) should carry three credentials before any commercial pesticide application by drone in California: an FAA Part 107 Remote Pilot Certificate for the pilot in command, an FAA Part 137 Agricultural Aircraft Operator Certificate for the business, and a state aerial-category pesticide applicator license. In California the state credential is issued by CDPR (CalEPA); you can ask the operator for the applicator license number and verify it with the agency directly. A current certificate of insurance with chemical drift coverage and the operator's Section 44807 exemption number are reasonable to request alongside the license itself.

Typical drone spraying rates of $18 to $30 per acre in the region typically covers the application itself: drone calibration, GPS-guided mission planning, mixing and loading product into the tank, the labor and machine time to fly the field, and a written FIFRA Part 170 application record (date, time, product, EPA reg number, rate, weather, field ID). Pesticide product, surfactants and adjuvants are usually supplied by the farmer and excluded from the per-acre rate. Common surcharges include long travel past the operator's standard radius, after-hours or emergency turnaround, fields with steep terrain or significant obstructions, and minimum-acreage charges below a stated field size. Get inclusions and exclusions in writing before any application.
