Abstract

BACKGROUND Canada thistle [Cirsium arvense (L.) Scop.] is a perennial weed that is difficult to control due to its extensive root system and prolific seed production. Although herbicides such as clopyralid provide effective control, they are not suitable for all production systems. Electrical weed control (EWC) is a nonchemical method that applies high voltage to plant tissues, causing irreversible cellular damage through loss of cellular integrity. This study evaluated the efficacy of EWC using a commercial tractor-mounted unit (EH30; Zasso), clopyralid, and integrated EWC-clopyralid programs for managing C. arvense, including single and sequential applications of each approach. RESULTS In Corvallis, EWC provided 39% and 53% control with one and two applications, respectively, whereas in Canby, control increased from 38% with a single application to 94% with two applications. Clopyralid provided 96% control with a single application and 95% with two applications in Corvallis, compared with 43% and 78% in Canby. Two EWC applications reduced shoot biomass by 95% in Canby. Combined treatments were highly effective: EWC followed by clopyralid achieved 89% control in Corvallis and 87% in Canby, and the reverse sequence achieved 98% control. CONCLUSION EWC provided transient control of C. arvense, and integration with clopyralid improved control, supporting its role in integrated weed management. Because C. arvense is a perennial species, multiyear studies are needed to determine the long-term effectiveness of EWC. © 2026 The Author(s).

用电除草和氯吡唑啉管理鸢尾草。

加拿大蓟[Cirsium arvense (L.)]吟游诗人。是一种多年生杂草，由于其广泛的根系和丰富的种子产量而难以控制。虽然除草剂如氯吡唑啉提供有效的控制，但它们并不适用于所有的生产系统。电除草（EWC）是一种对植物组织施加高压的非化学方法，通过细胞完整性的丧失造成不可逆的细胞损伤。本研究评估了EWC使用商用拖拉机安装装置（EH30; Zasso）、氯吡唑啉和集成的EWC-氯吡唑啉程序管理阿芬塞菌的效果，包括每种方法的单次和连续应用。结果在Corvallis， EWC在1次和2次施用时的控制效果分别为39%和53%，而在Canby， EWC在1次施用时的控制效果从38%上升到94%。在科瓦利斯，单次使用氯吡啉提供96%的对照，两次使用氯吡啉提供95%的对照，而在坎比，这一比例分别为43%和78%。两次EWC施用使Canby的茎部生物量减少了95%。联合治疗效果较好：EWC加氯吡柳酮对Corvallis的控制率为89%，对Canby的控制率为87%，相反顺序的控制率为98%。结论ewc对黄花蓟马有短暂的控制作用，与氯吡啉联用可提高黄花蓟马的控制效果，支持其在杂草综合治理中的作用。由于黄松是多年生植物，因此需要多年的研究来确定EWC的长期有效性。©2026作者。由John Wiley & Sons Ltd代表化学工业协会出版的《害虫管理科学》。
