虽然植物病害一直是科学研究的主题，但人们对具体食品部门内主要行为者对植物病害风险的看法知之甚少。借鉴风险和不确定性的概念，并采用深入访谈，本文探讨了在英国小麦部门的地方性植物病害风险的方式被认为是由关键的“上游”和“下游”企业，以及农民和农学家管理。大多数受访者认为，植物病害是一种可控的风险，主要存在于小麦部门的生产环节（即农民）。这种假定的“控制”主要是基于植物保护产品（如杀真菌剂）的可获得性，这些产品可降低植物疾病爆发的风险感。因此，可能会出现种植抗病性较低的高产小麦品种的趋势。根据欧盟立法和气候变化可能禁止某些杀菌剂被认为是未来的威胁，可能会增加不确定性，并改变“控制”和“抗性”之间的平衡，后者通过使用更具抗病性的小麦品种。需要进一步研究植物病害的影响，以及小麦部门的不同行为者将如何为今后控制植物病害和发展更综合的植物病害管理系统作出贡献。
While plant diseases have been the subject of scientific research, little is known about the perceptions of key actors towards plant disease risk within specific food sectors. Drawing on concepts of risk and uncertainty, and using in-depth interviews, this paper examines the ways in which endemic plant disease risks in the UK wheat sector are perceived and managed by key ‘upstream’ and ‘downstream’ businesses, as well as by farmers and agronomists. A majority of interviewees feel that plant disease is a controllable risk and one that rests mainly at the point of production (i.e. with farmers) within the wheat sector. This assumed ‘control’ is based mainly around the availability of plant protection products (e.g. fungicides) which reduce the sense of risk attributable to outbreaks of plant disease. As a consequence, there can be a tendency to grow higher-yielding wheat varieties that are less disease-resistant. The potential banning of certain fungicides under EU legislation and climate change are perceived future threats that could increase uncertainty and change the balance between ‘control’ and ‘resistance’, the latter through the use of more disease-resistant wheat varieties. Further research is needed on the perceived impacts of plant diseases and on how different wheat sector actors will contribute to the future control of plant diseases and the development of more integrated systems of plant disease management.
