遗传抗性是作物传染病管理的基础。然而，病原体的快速进化正在导致抗性的崩溃，并威胁到疾病控制。最近的研究工作已经确定了旨在破坏病原体适应和防止崩溃的抗性基因部署策略。到目前为止，此类战略的实际应用有限。在这篇论文中，我们着重于将应用进化研究转化为科学知情的管理策略以控制病原体适应所面临的社会经济挑战。我们为抗性的经济价值制定了一个概念框架，并表明，除了各种直接好处外，抗性还给农民和社会带来了相当大的间接和非市场价值。与进化进程相关的不确定的时间框架、难以分配遗传资源的所有权以及缺乏治理，使利益攸关方参与管理战略的动机变得复杂。这些相互作用的生物、社会经济和体制复杂性表明，抗药性崩溃应被视为一个邪恶的问题，利益攸关方之间的迫切要求往往相互冲突，没有简单的原因或解决方案。促进吸收解决可持续作物病害管理中复杂问题的科学研究成果，将需要教育、激励、立法和社会变革相结合。本文是“不断变化的世界中的传染病生态和进化”专题的一部分。
Genetic resistance forms the foundation of infectious disease management in crops. However, rapid pathogen evolution is causing the breakdown of resistance and threatening disease control. Recent research efforts have identified strategies for resistance gene deployment that aim to disrupt pathogen adaptation and prevent breakdown. To date, there has been limited practical uptake of such strategies. In this paper, we focus on the socio-economic challenges associated with translating applied evolutionary research into scientifically informed management strategies to control pathogen adaptation. We develop a conceptual framework for the economic valuation of resistance and demonstrate that in addition to various direct benefits, resistance delivers considerable indirect and non-market value to farmers and society. Incentives for stakeholders to engage in stewardship strategies are complicated by the uncertain timeframes associated with evolutionary processes, difficulties in assigning ownership rights to genetic resources and lack of governance. These interacting biological, socio-economic and institutional complexities suggest that resistance breakdown should be viewed as a wicked problem, with often conflicting imperatives among stakeholders and no simple cause or solution. Promoting the uptake of scientific research outcomes that address complex issues in sustainable crop disease management will require a mix of education, incentives, legislation and social change. This article is part of the theme issue ‘Infectious disease ecology and evolution in a changing world’.
