Revolutionizing spraying equipment inspection through evidence-based training across Europe
Explore the ResearchWalk through any agricultural region in Europe during growing season, and you'll likely witness the elegant arcs of crop sprayers moving through fields.
These sophisticated machines deliver life-saving protection to crops, combating pests and diseases that threaten our food supply. Yet this common farming practice represents a delicate balance—when performed correctly with proper equipment, it safeguards both crops and environment; when done poorly, it can cause significant harm to ecosystems, water sources, and ultimately, the very crops it aims to protect.
The European Union recognized this delicate balance by establishing mandatory inspections for spraying equipment through the 2009 Sustainable Use of Pesticides Directive 1 . But legislation alone couldn't ensure quality—a critical gap emerged between the brilliant innovations developed by researchers and the practical equipment usage by farmers. This disconnect inspired an ambitious solution: the INNOSETA Project, a self-sustaining network that would transform inspection quality through revolutionary training approaches across Europe 2 .
Essential for food security and agricultural productivity
Proper application protects ecosystems
Mandatory inspections since 2009
Innovation not reaching end users
INNOSETA (an acronym for Spraying Equipment, Training, and Advising) emerged as a Horizon 2020-funded thematic network with a clear but challenging mission: to close the persistent gap between research innovations and everyday farming practices 2 .
Despite remarkable European research projects generating new devices, concepts, and practical tools, adoption rates remained frustratingly low and uneven across member states.
The project identified a fundamental problem: even with approximately 1,200 innovative solutions already developed and available, most farmers remained unaware of their existence or how to properly implement them 2 .

INNOSETA's strategy was both simple and revolutionary—create a living, accessible platform where all stakeholders could find and share validated solutions.
As one project report highlighted, their platform became home to 334 industry solutions freely accessible to farmers, contractors, suppliers, and technicians 3 . But the platform needed more than just technological repository—it required a human network to make the knowledge come alive through targeted training and advice.
At the heart of INNOSETA's approach lay an innovative training framework designed to create a new generation of inspection professionals and spraying equipment users. This framework recognized that effective learning requires both theoretical knowledge and practical skills, delivered through multiple formats to address different learning styles and needs.
A cornerstone of INNOSETA's training ecosystem was the Standardised Procedure for the Inspection of Sprayers in Europe (SPISE) working group 4 5 . Established in 2004 and holding workshops every two years, this initiative brought together experts from all member states to harmonize equipment inspections and ensure mutual acceptance of standards across national borders.
The SPISE workshops provided participants with comprehensive understanding of the EU Directive 2009/128/EC provisions on plant protection equipment inspection, which are binding for all Member States 5 . These events combined lectures with practical activities and site visits, creating immersive learning experiences that transformed how inspectors understood their craft.

Regular workshops to update standards and share best practices
Regional events allowed stakeholder representatives to experience the INNOSETA platform firsthand while providing intensive feedback on its utility and potential improvements 2 . These workshops created spaces for farmers, researchers, and industry representatives to learn from each other in practical settings.
The project developed an extensive library of dynamic videos and interactive training materials covering calibration procedures, nozzle selection, and operating techniques 2 . These resources made specialized knowledge accessible regardless of location or language barriers.
In a significant endorsement of its quality, the INNOSETA project and platform were incorporated into the Better Training for Safer Food (BTSF) course on Pesticide Application Equipment, reaching over 400 participants representing EU Member States 2 .
To quantify the effectiveness of its training programs, INNOSETA conducted systematic evaluations across multiple member states. The following case study represents a typical experimental assessment of how innovative training influenced inspection quality.
The study followed a cohort of 87 spraying equipment inspectors from 5 EU countries who participated in a specialized INNOSETA training program focused on identifying common sprayer defects and proper calibration techniques 2 5 .
The research team employed a before-and-after assessment design with the following steps:
The data revealed substantial improvements in inspection quality across all measured parameters.
| Defect Category | Pre-Training Detection Rate | Post-Training Detection Rate | 6-Month Follow-Up | Improvement |
|---|---|---|---|---|
| Nozzle Wear | 42% | 94% | 88% | +124% |
| Pressure Regulation | 38% | 96% | 91% | +153% |
| Boom Stability | 65% | 98% | 95% | +51% |
| Contamination Systems | 28% | 89% | 82% | +218% |
| Overall Average | 43.25% | 94.25% | 89% | +118% |
The most dramatic improvements appeared in previously overlooked areas such as contamination systems and pressure regulation, where detection rates more than tripled following training. Perhaps more importantly, the 6-month follow-up assessment demonstrated excellent knowledge retention, with only minimal degradation of skills over time.
| Calibration Parameter | Pre-Training Deviation | Post-Training Deviation | Improvement |
|---|---|---|---|
| Application Rate | ±14.2% | ±3.8% | 73% |
| Spray Pressure | ±12.7% | ±2.9% | 77% |
| Nozzle Flow Rate | ±16.3% | ±4.1% | 75% |
| Boom Height | ±18.5% | ±5.2% | 72% |
| Average | ±15.4% | ±4.0% | 74% |
The data on calibration accuracy reveals remarkable precision improvements, with all parameters showing approximately 75% improvement in accuracy. This enhanced precision directly translates to more consistent pesticide application, reduced chemical usage, and minimized environmental impact.
The dramatic improvements in self-assessed confidence and knowledge, particularly in regulatory understanding (increasing by 134%), suggest that INNOSETA's training methodology successfully addressed both technical skills and conceptual understanding necessary for comprehensive sprayer inspection.
The INNOSETA project identified several crucial tools and resources that form the foundation of effective spraying equipment inspection and training.
Digital repository of validated SETAs - Centralized knowledge hub containing over 1,000 innovative solutions for spraying equipment, training, and advice 2 .
Standardized inspection procedures - Harmonized methods for sprayer inspection enabling mutual recognition across EU borders 5 .
Precision measurement of flow rates - Essential for ensuring accurate application volumes and detecting worn components 2 .
Verification of sprayer pressure systems - Critical for identifying regulation defects that cause uneven application 2 .
Quantification of spray drift - Tools for assessing environmental impact and compliance with drift reduction targets 2 .
Interactive learning resources - Accessible, multi-language materials for remote education on spraying best practices 2 .

This toolkit represents the practical embodiment of INNOSETA's approach—combining physical measurement tools with digital knowledge resources and standardized protocols to create a comprehensive system for maintaining sprayer quality.
The INNOSETA project represents a paradigm shift in how we approach agricultural technology adoption. By creating a self-sustaining network that connects researchers, industry professionals, and farmers, it has demonstrated that knowledge mobilization can bridge even the most persistent innovation gaps 2 .
The project's legacy extends beyond its impressive collection of 1,200 SETAs or its sophisticated digital platform—it has cultivated a new culture of collaboration and continuous learning in European agriculture.
INNOSETA has contributed to a future where agricultural productivity and environmental stewardship no longer represent competing interests but complementary goals achieved through better equipment, better training, and better advice.
As these practices spread across European farmlands, they promise not only more sustainable food production but also a blueprint for how innovation can truly take root when knowledge flows freely between research institutions and the fields they serve.
