This article describes an investigation into how to build agency among growers so they take the lead in transforming their own activity of managing whiteflies. The study shows how the principle of Transformative Agency by Double Stimulation (TADS) was applied in a formative intervention based on the Change Laboratory method for developing pest management among greenhouse vegetable producers in Finnish Ostrobothnia. The data comprise audio recorded sessions, documentary data and observations produced and collected during the intervention. The results show how the collective construction of a continuous series of models during the intervention played an important role in learning, prompting TADS among the participants and working as a communication tool for the practitioners' different conceptualizations of the problem and possible solutions. The models allowed materializing and expanding the way the participants understood the temporal, functional and spatial aspects of the problem. In the study, TADS took place through conflict of stimuli and motives, first stimulus, auxiliary breaking-away second stimulus, and actions that were initiated to improve the management of the problem at hand. In conclusion, the principle of double stimulation was useful to produce transformative agency, helping transform the activity of pest management among the horticultural producers.

本文描述了一项关于如何在种植者之间建立代理权的调查，以便他们带头转变自己管理粉虱的活动。该研究展示了如何将双重刺激转化机构 (TADS) 的原则应用于基于变革实验室方法的形成性干预，以在芬兰 Ostrobothnia 的温室蔬菜生产者中开展害虫管理。数据包括在干预期间产生和收集的音频记录会话、文件数据和观察。结果表明，在干预期间，一系列连续模型的集体构建如何在学习、促进参与者之间的 TADS 以及作为从业者对问题和可能解决方案的不同概念化的交流工具中发挥重要作用。这些模型允许具体化和扩展参与者理解问题的时间、功能和空间方面的方式。在这项研究中，TADS 是通过刺激和动机的冲突、第一次刺激、辅助脱离第二次刺激以及为改善手头问题的管理而发起的行动发生的。综上所述，双重刺激原则有助于产生转化机构，有助于转化园艺生产者的病虫害管理活动。以及为改进手头问题管理而发起的行动。综上所述，双重刺激原则有助于产生转化机构，有助于转化园艺生产者的病虫害管理活动。以及为改进手头问题管理而发起的行动。综上所述，双重刺激原则有助于产生转化机构，有助于转化园艺生产者的病虫害管理活动。
