Cirsium arvense management with electrical weed control and clopyralid

open access: yesPest Management Science, Volume 82, Issue 7, Page 6575-6584, July 2026.
Electrical weed control (EWC) treatments reduced Cirsium arvense biomass by ≤95% and suppressed new shoot emergence by 70–95%, achieving control comparable to clopyralid. Sequential or integrated applications enhanced efficacy, demonstrating EWC's potential as a nonchemical tool for perennial weed management in orchard systems.
