System Confidence and Skepticism in Pesticide-Residue Risk Perception—A Latent Profile Analysis of Greek Agronomists

Pesticide-residue risk perceptions among agricultural professionals are shaped by factors that extend beyond knowledge gaps. This study examines how trust in regulatory systems and information sources jointly shape residue-related attitudes among Greek agronomists. We used principal components analysis (PCA) to identify coherent domains and then latent profile analysis (LPA) to derive person-centered profiles based on standardized component scores. Two dominant profiles emerged, differing in regulatory confidence, reliance on institutional/scientific information channels, and comparative risk framing. Residue-Concerned Skeptics expressed lower confidence in enforcement capacity (implementation and staffing) and in the system’s alignment with other EU Member States, together with concerns about chronic pesticide exposure. The System-Confident profile reported higher regulatory confidence and greater reliance on official and scientific channels, as well as stronger endorsement of IPM effectiveness and comparative risk rankings. External validation supported profile differences in perceived training adequacy, IPM beliefs, and organic avoidance behavior. Professional involvement in plant protection and older age were associated with membership in the System-Confident profile. These findings suggest that interventions should emphasize clear communication, capacity building, and address concerns about chronic exposure, beyond information provision alone.
