Globalization causes plant production systems to be increasingly threatened by invasive pests and pathogens. Much research is devoted to support management of these risks. Yet, the role of growers' perceptions and behavior in risk management has remained insufficiently analyzed. This article aims to fill this gap by addressing risk management of invasive pathogens from a sociopsychological perspective. An analytical framework based on the Theory of Planned Behavior was used to explain growers' decisions on voluntary risk management measures. Survey information from 303 Dutch horticultural growers was statistically analyzed, including regression and cluster analysis. It appeared that growers were generally willing to apply risk management measures, and that poor risk management was mainly due to perceived barriers, such as high costs and doubts regarding efficacy of management measures. The management measures applied varied considerably among growers, depending on production sector and farm-specific circumstances. Growers' risk perception was found to play a role in their risk management, although the causal relation remained unclear. These results underscore the need to apply a holistic perspective to farm level management of invasive pathogen risk, considering the entire package of management measures and accounting for sector- and farm-specific circumstances. Moreover, they demonstrate that invasive pathogen risk management can benefit from a multidisciplinary approach that incorporates growers' perceptions and behavior.
全球化导致植物生产系统越来越受到入侵性害虫和病原体的威胁。大量研究致力于支持这些风险的管理。然而，种植者对风险的感知和行为在风险管理中的作用仍未得到充分分析。本文旨在从社会心理学的角度来填补这一空白，探讨入侵性病原体的风险管理问题。本文使用基于计划行为理论的分析框架来解释种植者对自愿风险管理措施的决策。对 303 名荷兰园艺种植者的调查信息进行了统计分析，包括回归和聚类分析。结果表明，种植者普遍愿意采取风险管理措施，而管理不善的主要原因是认为成本高，对管理措施的效果存在疑虑等障碍。根据生产部门和农场的具体情况，种植者采取的管理措施差异很大。研究发现，种植者的风险感知在其风险管理中发挥了作用，尽管因果关系尚不清楚。这些结果强调了在农场层面上管理入侵性病原体风险时需要采用整体方法，考虑到整套管理措施，并考虑到部门和农场的具体情况。此外，研究结果表明，入侵性病原体风险管理可以受益于多学科方法，该方法将种植者的感知和行为纳入其中。
