The IAA publication entry reviewed lists UAM 016, Version 1.
Drone chemical sprayer or mapping service: describe the job
Before asking anyone for a quote, write down whether you need photographs, a crop map, material spreading or liquid application. Name the crop, field, aircraft and material, and describe neighbouring properties, access routes and water features.
For a mapping service, specify the output you will receive: imagery, a mapped observation or an agronomist’s interpretation. Ask who turns that information into a management decision. A map showing variation does not by itself identify its cause or prescribe a treatment.
For an application proposal, give the full marketed product name and the PCS number. Keep a nutrition product separate from a plant protection product, and avoid the loose phrase “crop spray” for materials with different regulatory questions.
Check the aviation operation with IAA
In the Open category, the unmanned aircraft must not drop material. For a spraying proposal, use the Specific-category assessment route in UAM 016.
Ask the proposed operator which current authorisation or declaration covers the actual aircraft and the actual operation. Ask to see the full approval documents and check their scope, operator, limitations and site conditions, rather than relying on cropped certificate images in marketing. Find out who operates the aircraft and who supplies it. Send any question that stays open to IAA through its published contact route.
Can you use a drone to spray pesticides? Check the agricultural approval
A pesticide proposed for aerial spraying needs explicit approval for that method under the agricultural framework. Aviation evidence and an Irish pesticide authorisation address different parts of the proposal.
Prepare the product identity, the crop or situation, the application method and the location, and put them to DAFM. Ask for a written answer naming the route and conditions for that specific operation, and keep it with the commercial proposal. A foreign label, a machine demonstration or permission issued for another material does not answer the question for your product: if the product or method changes, ask again.
Search the Irish product database by marketed name, active substance or function/crop. Use the register guide to locate the exact formulation before discussing its proposed method.
Ask what the survey can measure
Aerial imagery can be an input to a precision-agriculture decision, but the service must explain what information is being produced. Crop sensing can use drone-mounted, tractor-mounted, satellite or handheld systems. Combine sensing with other field information and inspect weeds on the ground to understand variation.
Ask whether the output is an ordinary photograph, an interpreted vegetation image, a weed-location map or another defined measurement, and ask for the sensor and processing to be explained in words your adviser can use. Do not accept an unexplained colour scale as a diagnosis of nutrient deficiency, disease or herbicide resistance.
Give the surveyor the crop, variety, establishment history and the question you are investigating. For a pale patch, say when it was first seen and whether drainage, soil or management differ there. Ask your crop adviser which ground observations would test the interpretation.
Check whether the map is usable by the farm
Ask for a sample deliverable before you buy and open it with your adviser in the software you will actually use. Check that the field boundary is recognisable, the legend explains each class and the capture date is visible. If contractors need printed maps, ask for that format as well.
If the file has to move between systems, ask about coordinate reference, units and compatibility, and who will check the import before anyone acts on it.
Ask what the reported area covers: the field surveyed, the image successfully processed, the interpreted target or a proposed treatment polygon. A coverage percentage should state what it is a percentage of, so you can tell an imaging gap from a deliberate exclusion.
For repeated surveys, ask for a consistent way to identify the same locations, and for any change of boundary, sensor, processing or classification to be disclosed. Otherwise an apparent change between two maps may not be a change in the crop.
Contract spraying prices: separate the charge components
Ask the supplier to itemise the area charge, mobilisation, labour, materials, extra visits and minimum invoice, with the area unit on every line and tax shown the way the supplier states it, so two offers compare on the same basis. Ask what happens if weather postpones the work or only part of the field is done, and get the cancellation and rescheduling terms in writing. Do not assume a price per acre includes repeat journeys or a follow-up operation.
For imagery or advice, list the files and interpretation included. For application, agree which operation records will come back to you.
Invented example for arithmetic only: a 40-acre job, a fictional €120 mobilisation and €8 per acre, materials excluded: €120 + (40 × €8) = €440, or €11 per acre. These are not Irish market prices. Add the materials and other agreed costs before comparing offers, and recalculate on the contract’s pricing basis if the area changes.
Also ask what the priced area is: the field boundary, the survey coverage, the intended treatment area or the area actually completed. Ask for a marked plan of what the quotation covers, including headlands, excluded strips and untreated areas, and ask how a difference between the supplier’s measured area and your map will be settled. For a camera survey, the priced deliverable may be a report rather than acres treated.
Keep your spray records in one place. Free to start.
Test any minimum charge at your actual job size. Invented comparison: Supplier A offers €10 per acre with a €250 minimum invoice; Supplier B offers €100 mobilisation plus €8 per acre. At 10 acres A costs €250 and B €180; at 40 acres A costs €400 and B €420. The ranking flips because the structures differ. Ask whether a minimum applies to the whole invoice, one visit or one line, and whether it already includes mobilisation. If several fields make one visit, ask whether the minimum applies to the combined area, and how far-apart fields change the offer.
Identify the operator and machine
For a small drone sprayer, ask for the exact aircraft model and the documents covering the proposed operation, and settle the aviation and pesticide questions above for that machine and job before you accept a booking.
Ask who will carry out the application and for their professional-user identity, and record any change of operator in the correspondence. A company name and the person flying the machine answer different questions.
Check the equipment's applicable testing requirements and calibration before work. Use the equipment-testing guide to check the current schedule, and query any document that does not say whether it is a test certificate, a calibration result or a service invoice.
Plan spot spraying by drone in the site brief
For spot spraying, mark the proposed treatment patches and the areas to stay untreated, and agree who identifies the target and supplies the final boundary. The application-method guide explains spot treatment versus whole-field application. For trees, give the operator the layout, canopy dimensions and access constraints, and ask how placement will be assessed.
Give the operator a field outline marking roads, homes, footpaths, overhead obstructions and neighbouring work. Say who controls entry to the site and who can stop the job if conditions change. Ask for the working area, a contingency plan and the precautions for people nearby, and check conflicts with livestock, harvest work and other contractors.
Keep the flight plan and the pesticide work instruction separate but under one job reference, and circulate any revision to the responsible people. Confirm the final scope before you accept a mobilisation date.
Make the weather decision on the actual job
Check wind speed, direction and the available weather window before work. Agree who makes the final decision and how a postponement is communicated. If conditions change during the job, record pauses, reduced areas and abandoned sections, and mark the completed boundary and the work still planned. Apply the agreed rescheduling terms if the visit is postponed, and charge any extra cost only against actual extra work.
Agree the record fields before departure
Include the crop-record fields: date, product, PCS, crop or situation, location, treated area or tonnage, product rate, water volume, method, buffer information, relevant nozzle detail, IPM reason, PU identity and sprayer-certificate reference. Compare that layout with the contractor’s proposed record. The spray-sheet guide explains each field. An invoice alone may describe the charge without answering every application question, so ask for enough to connect the operation with your own field and product records.
Article 4 of EU 2023/564 requires the contracted professional user to give the contracting person access to or a copy of the records without undue delay or restrictions.
Agree a delivery route and a named recipient. Match the returned record to the work completed, query missing locations or quantities with the operator, and file the operator’s reply with the spray record.
Hand the area back clearly
Give the manager the actual product conditions and the access or harvest information for the completed work, and use the worker re-entry guide to brief staff who were not there. Keep the final work boundary, contractor correspondence and application record together. If a crop concern appears later, record your observations and get a competent assessment before assigning a cause.
Spraying drones for crops: agriculture drones, DJI Agras T30 and heavy-lift sprayers
People search for aerial spraying drones, ag spraying drones, agri drone sprayers, spray drones, a sprayer drone for farming, crop spraying with drones, crop dusting drones, drones that spray crops, drones that can spray crops, a spraydrone, a copter spray service and drones with sprayers. They also search by size and make: a 10 liter agriculture drone, the DJI Agras T20, T30 and T40 agriculture drones, the largest or biggest spray drone, a heavy lift drone sprayer and a petrol drone for agriculture. All of them are the same decision in Ireland: the aircraft, its operator and the product must each be cleared as described in the sections above.
Drones for spraying weeds, drones to spray pesticides, using drones to spray crops, drones for spreading fertilizer and an agriculture drone for spraying fertilizer and pesticides are different jobs from mapping. For the best drone sprayer, compare the operator's documents and records rather than the tank size.
Drone spraying companies and drone spraying near me
Drone agriculture spraying companies and drone spraying companies are contractors. Before you book a drone sprayer near you, ask for the aircraft model, the documents for the proposed operation, the product and its approval for spraying by air, and the record they will return after the job. Use the contractor handover and record fields above to hold them to it.
Next step
Resolve the aviation and pesticide permissions before booking application work; agree the spray-record handover.
