The movement of plants through the ornamental plant trade presents a major source of risk for the introduction and spread of plant pests and pathogens. To minimise the likelihood of infested or infected plants moving through the value chain, individual businesses can adopt a range of biosecurity practices to prevent introduction on site, as well as detecting and then containing or eradicating any plant pests or pathogens present. However, a major additional source of risk is the arrival of unhealthy plants sourced from a supplier. Using the example of bacterial plant pathogen which has a large host range and potentially devastating economic and environmental impacts, we highlight the importance of trust when businesses navigate the risks of sourcing plants. Through interviews and a survey with a range of plant businesses, we show (i) how two general types of risk-relational risk associated with suppliers acting in good faith, and performance risk associated with suppliers having the ability to perform as expected-can be applied to the challenge of sourcing healthy plants, (ii) how businesses respond to these risks through behaviours based on trust and control, and (iii) the potential outcomes of trust-based and control-based behaviours in the presence of a hard to detect pathogen such as . We conclude that trust is a significant component in decision-making in the live plant trade, and as such any behavioural interventions designed to encourage better biosecurity practices in the industry should capitalise on this understanding to strengthen responses and avoid undermining of effort.
观赏植物贸易中植物的流动是植物害虫和病原体引入及传播的主要风险来源。为了尽量减少受侵染或感染的植物在价值链中流动的可能性，个体企业可以采取一系列生物安全措施，以防止在现场引入，同时检测并控制或根除任何存在的植物害虫或病原体。然而，另一个主要的风险来源是来自供应商的不健康植物的到货。以寄主范围广泛且可能产生巨大经济和环境影响的细菌性植物病原体为例，我们强调企业在应对采购植物风险时信任的重要性。通过对一系列植物企业进行访谈和调查，我们展示了：（i）与供应商诚信相关的两种一般类型的风险——关系风险，以及与供应商按预期表现能力相关的绩效风险——如何应用于采购健康植物的挑战；（ii）企业如何通过基于信任和控制的行为来应对这些风险；（iii）在存在诸如[未提及具体病原体名称]这种难以检测的病原体时，基于信任和基于控制的行为可能产生的结果。我们得出结论，信任是活体植物贸易决策中的一个重要组成部分，因此，任何旨在鼓励该行业更好地实施生物安全措施的行为干预都应利用这一认识来加强应对措施，并避免努力受到破坏。
