Abstract There is a growing concern in society about the continuing intensive usage of pesticides in farming and its effects on environmental and human health. Insight in the intentions of farmers to reduce pesticide use may help identify pathways towards farming systems with reduced environmental impacts. We used the Reasoned Action Approach to identify which social-psychological constructs determine farmers' intentions to decrease pesticide use. We analysed 681 responses to an online survey to assess which constructs drive intention, and identified which beliefs pose barriers and drive the motivation of farmers to decrease pesticide use. Our results show that the intention to reduce pesticide use is strongly determined by whether other farmers also act. Furthermore, farmers perceive limited capacity and autonomy to reduce pesticide use, and motivations to reduce pesticide use were based on environmental considerations. Finally, decreasing pesticide use was considered risky, but the relative importance of risk attitude was offset by the environmental considerations of farmers. This indicates that farmers need successful examples of how to decrease pesticide use, either via exchange with peer farmers or knowledge provisioning on alternative pest control methods. These insights may be useful to direct policy making to influence farmers' intentions to decrease pesticide use.

改变习惯：是什么决定了农民减少农药使用的意图？

摘要 社会上越来越关注农药在农业中的持续大量使用及其对环境和人类健康的影响。深入了解农民减少农药使用的意图可能有助于确定通往减少环境影响的农业系统的途径。我们使用理性行动方法来确定哪些社会心理结构决定了农民减少农药使用的意图。我们分析了对在线调查的 681 份回复，以评估哪些结构驱动意图，并确定哪些信念构成障碍并驱动农民减少农药使用的动机。我们的结果表明，减少农药使用的意图很大程度上取决于其他农民是否也采取行动。此外，农民认为减少农药使用的能力和自主权有限，减少农药使用的动机是基于环境考虑。最后，减少农药使用被认为是有风险的，但风险态度的相对重要性被农民的环境考虑所抵消。这表明农民需要通过与同行农民交流或提供有关替代害虫防治方法的知识来减少农药使用的成功范例。这些见解可能有助于指导政策制定以影响农民减少农药使用的意图。这表明农民需要通过与同行农民交流或提供有关替代害虫防治方法的知识来减少农药使用的成功范例。这些见解可能有助于指导政策制定以影响农民减少农药使用的意图。这表明农民需要通过与同行农民交流或提供有关替代害虫防治方法的知识来减少农药使用的成功范例。这些见解可能有助于指导政策制定以影响农民减少农药使用的意图。
