G.S. Long Company

Ask G.S. Long Company for four documents to confirm credentials: the Part 107 Remote Pilot Certificate number, the Part 137 Agricultural Aircraft Operator Certificate, the state aerial-category pesticide applicator license, and a certificate of insurance carrying chemical drift coverage. In Washington the state credential is issued by Washington State Department of Agriculture (WSDA); you can ask the operator for the applicator license number and verify it with the agency directly. The Section 44807 exemption number is the fourth piece, applicable to any drone over 55 lbs gross weight.

Typical drone spraying rates of $12 to $22 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.
