Do not carry out or advertise a plant-protection-product application by drone unless the operator can produce current written evidence for every applicable aviation, aerial-spraying, Irish product-authorisation/label and professional-use/site requirement. Hexagon.ie did not verify a general Irish route or product label authorising routine agricultural PPP application by drone.
If your goal is better application decisions, start with drone mapping and crop monitoring. Those workflows can identify field variation, wet zones, weed patches or crop stress areas for adviser review without implying drone spraying is available today.
The Four Separate Approval Gates
1. Aviation operation
EASA Regulation 2019/947 classifies the operation by risk. Open-category work must stay within all relevant subcategory limits; operations outside those limits may fall into the Specific category. EASA and the IAA explain that a Specific-category operation may need a standard-scenario declaration or an operational authorisation. An IAA authorisation addresses aviation safety for the described operation—it does not authorise a plant protection product or override its label.
Confirm operator registration, remote-pilot competency, aircraft/payload configuration, visual-line-of-sight or other operating basis, people distances and the current IAA UAS geographical-zone conditions for the exact site. The IAA updated its U04 geographical-zone notice on 22 July 2026.
2. EU aerial-spraying control
Article 9 of Directive 2009/128/EC establishes a general prohibition on aerial spraying. It permits derogations only in special cases and subject to conditions, including approval by the competent authority, an approved operator/aircraft/equipment route, no viable alternatives or clear advantages in reduced impacts, and specific product approval for aerial spraying. A technology claim about lower drift does not create that derogation.
3. Irish PPP authorisation and label
DAFM’s Pesticide Registration and Control Division maintains the Irish plant protection product database and labels. A product must be authorised for the proposed use, crop, rate, timing and method. PRCD guidance states that products must be used as directed on the label and that using an off-label extension outside its instruction is an offence. Never infer drone application permission from the fact that a product is registered for ground application.
4. Professional user, equipment, site and environmental controls
DAFM’s March 2025 sprayer guidance says anyone applying a PPP designated for professional use, regardless of method or quantity, must be trained and registered as a Professional User. Product records, equipment inspection/calibration, weather, water protection, PPE and label conditions may apply. Landowner permission, neighbouring exposure, water bodies, protected sites, livestock, bystanders and data protection also need assessment.
A seller’s CE documentation, an IAA operator registration, a Specific-category approval, a product’s presence in the Irish register or a Professional User number cannot individually authorise the complete spraying operation.
Evidence to Request Before Any Proposal
- The operator registration and remote-pilot competency relevant to the operation.
- The precise Open-category basis, standard-scenario declaration or operational authorisation, including aircraft and payload configuration.
- The current geographical-zone result and any site-specific permission or condition.
- The competent-authority basis for any Article 9 aerial-spraying derogation relied upon.
- The Irish PPP registration and current label explicitly supporting the crop, pest, dose, timing and aerial/drone application method.
- The Professional User registration and required equipment inspection/calibration records.
- The written risk, drift, water, bystander, livestock, neighbouring-property, emergency and record-keeping controls.
- Insurance confirmation that specifically covers the aircraft, payload, operation and chemical application.
If any document is missing, ambiguous, expired or relates to another country, aircraft, product or method, stop and ask the IAA and DAFM/PRCD for current written direction. Do not rely on a future EU proposal, overseas example or vendor presentation.
What Can Be Done Now?
Mapping and monitoring are different operations from PPP application, but they still require lawful flights. A supportable near-term workflow is to collect imagery, identify relative variation, inspect those zones on the ground and take the evidence to an agronomist or adviser.
- Use drone mapping to create a dated orthomosaic or survey brief with known limitations.
- Use crop monitoring to compare zones and dates, then ground-truth before diagnosis.
- Keep crop, field, weather and inspection records separate from any unsupported prescription map.
- Check the PRCD database and current label before any ground-based PPP decision.
- Recheck IAA, EASA, EU and DAFM sources when the proposed operation changes.
No claim is made here that drone spraying will become generally available in Ireland on a particular date, that a specific aircraft or provider will be approved, or that spraying by drone will deliver a stated reduction, yield or saving.
