Frequently asked questions
Ask Terraplex Ag 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 Iowa the state credential is issued by IDALS; 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 is application-only — the chemical itself, surfactants and adjuvants are usually farmer-supplied. The rate covers calibration, RTK GPS flight planning, the labor to fly the field, mixing and loading from the supplied product, and the FIFRA Part 170 application record (date, time, product, EPA reg number, rate, weather, field ID). Watch for travel surcharges past a stated radius, weekend or emergency-turnaround premiums, terrain or obstruction add-ons, and any minimum-acreage floor on small fields. Confirm in writing.
