Two laws, not one — that's where most farmers start wrong
South Africa's drone spraying framework sits under two separate pieces of legislation that must both be satisfied before a spray tank is filled. The Civil Aviation Act (No. 13 of 2009) governs the aircraft, the pilot, and the airspace — enforced by SACAA. The Fertilisers, Farm Feeds, Agricultural Remedies and Stock Remedies Act (No. 36 of 1947) governs the chemical, the applicator, and the pest control operator — enforced by the Department of Agriculture.
Surveillance drones used for scouting, mapping, or livestock monitoring only trigger the Civil Aviation Act. The moment a spray tank is attached, Act 36 applies as well. Operating under one without the other is not a technicality — it exposes the operator to criminal liability and can invalidate crop-insurance claims.
What SACAA actually requires: the Part 101 stack
Drone registration
Every drone heavier than 250 g must be registered with SACAA using forms CA-47R1 through CA-47R5. Each aircraft receives a unique identification number that must be visibly displayed on the airframe. There is no threshold below which a commercial spray drone escapes this requirement.
Remote Pilot Certificate (RPC)
The pilot must hold an RPC issued by a SACAA-Approved Training Organisation (ATO). Prerequisites include a Class III medical certificate and X-rays, an English language proficiency assessment, and an aeronautical radiotelephony (R/T) proficiency certificate — with a functioning air-band radio carried during every flight.
Full-time RPC training at a recognised Johannesburg academy runs approximately R44,998 all-in (three weeks full-time or seven weeks part-time, SACAA exam fees included — indicative pricing as per current ATO listings). The SACAA fee for issuing the RPC, when lodged separately, is approximately R660 (indicative, based on the April 2026 fee schedule at caa.co.za/fees — verify before submitting).
RPAS Operator's Certificate (ROC)
Any commercial drone operation — including spraying a neighbour's field for payment — requires a business-level Unmanned Aircraft Systems Operating Certificate (UASOC, also called an ROC). Obtaining one requires a formal Operations Manual covering emergency protocols, flight planning, and maintenance; a Safety Management System; pilot rosters; and demonstrated safe operations capability.
SACAA's ROC issuance fee is approximately R4,210, plus approximately R840 per additional aircraft added to the certificate (indicative, April 2026 schedule).
Letters of Approval (RLA)
A separate Letter of Approval from the SACAA Director is required for each aircraft registered under a commercial ROC. Additional written SACAA approval is required for operations within 10 km of any aerodrome, helipad, or airport; near controlled, restricted, or prohibited airspace; and for any Beyond Visual Line of Sight (BVLOS) mission — a category that covers many large-field agricultural runs.
The standard operational ceiling is 400 ft (approximately 120 m) AGL. Spray drones typically work at 1–3 m above the canopy, but BVLOS rules apply to lateral distance from the operator, not only altitude.
The Act 36 layer: Pest Control Operator registration
If you spray for hire, you must also register as a Pest Control Operator (PCO) with "aerial application" specified as the field, under Act 36 of 1947. This gives you a P-number certificate. The process also requires completion of training as an aerial applicator under Pest Control Operators Regulations R98, followed by a supervised internship under an already-registered aerial application operator.
Before loading the tank, confirm that each agrochemical product you intend to apply is registered for aerial application by the Registrar of Act 36. Many labels restrict use to piloted aircraft only, at the manufacturer's discretion. A farmer can own a fully SACAA-compliant drone with a valid RPC and still be operating illegally because the herbicide label does not include a drone-aerial registration. All operations must comply with SANS 10118 (the SA National Standard for Aerial Application of Pesticides).
What the numbers look like
South Africa had roughly 60 activated spray drones in 2021. By 2025 that figure had grown to approximately 2,000 active spray drones, covering an estimated 1.6–2 million hectares per season.
The economics explain the growth. Fixed-wing manned aircraft typically run R400–R500/ha; helicopters R500–R700/ha. Licensed drone contractors have been quoting R250–R400/ha (indicative market rates).
A documented case from an 80-hectare smallholder sugarcane co-operative in northern KwaZulu-Natal illustrates what those rates translate to on the ground. After switching from tractor-based application to a licensed drone contractor, the co-operative recorded a 25% reduction in total spraying costs, 20–30% lower agrochemical volumes, a 6–12.5 t/ha yield increase, a two-percentage-point improvement in estimated recoverable crystal (the sugar-content metric), and a 10–14 day shorter ripening period enabling earlier harvest. Net annual gain was calculated at R8,400/ha — R672,000 across 80 ha — with soil compaction from tractor ruts in ratoon fields eliminated entirely.
On the capital side, a commercial spray drone in the DJI Agras T40/T50 class costs approximately R250,000–R400,000 (indicative). Operators serving large client bases report payback within 1–1.5 seasons when annualised benefits reach R8,000–R9,000/ha across fields.
Spray drones also use up to 90% less water than conventional methods — directly relevant in water-scarce regions like the Northern Cape and Free State — and are reported to be 75% more fuel-efficient than manned fixed-wing aircraft.
Own or contract? A practical frame
Small-scale farmers running fewer than 200 ha per season are generally better served by hiring a licensed contractor. The combined cost of RPC training, ROC application, PCO registration, and drone capital outweighs the benefit at low hectarage, and contractor availability in most cropping regions has improved considerably.
Smallholder co-operatives can pool resources under a shared contractor model and eliminate both the capital burden and the compliance overhead entirely.
For large-scale farmers or agri-service businesses handling more than 500 ha per season, owner-operator economics become favourable: payback within 1–1.5 seasons, with no dependency on contractor scheduling. An existing aerial application business can add a drone to an existing ROC for approximately R840 per aircraft (indicative), and likely already holds PCO registration.
Kyle-Jones Middleton, a grain farmer in Jacobsdal in the Free State, sprays over 900 hectares annually using drones: "We've managed to limit trampling in our crops once we've planted; we have no tractors in the fields. Sometimes being a few days late can make or break your season."
Compliance checklist
Before the first flight:
- Drone registered with SACAA (CA-47R1 form); registration number displayed on airframe
- Pilot holds valid RPC from a SACAA-approved ATO
- Pilot holds Class III medical certificate
- Pilot holds aeronautical R/T certificate and carries air-band radio on every flight
- Commercial operator holds ROC (UASOC) with approved Operations Manual
- Each aircraft holds an individual Letter of Approval (RLA)
- For spraying: PCO registration (P-number) obtained for aerial application under Act 36
- For spraying: each agchem product confirmed label-registered for aerial application
- Operations documented in accordance with SANS 10118
- No-fly zones verified: 10 km from aerodromes; 50 m from people, public roads, and property without owner consent
- BVLOS or near-controlled-airspace operations: written SACAA approval in hand
- Third-party liability insurance in place (mandatory for commercial operations)
Fee figures in this post are based on the SACAA schedule effective April 2026 and should be confirmed at caa.co.za/fees before submission.
