Control of ragwort (Senecio jacobaea L.) at advanced stages of growth using clopyralid



Control of ragwort (Senecio jacobaea L.) at advanced stages of growth using clopyralid



Plant Protection Quarterly 2(4): 168-173



Field trials were conducted on pasture sites near Deloraine, N. Tasmania in 1983-86. Clopyralid applied as a spot spray to S. jacobaea at the late rosette and shooting stages completely prevented seed production and gave a very high level of mortality at rates as low as 0.3 g/litres, although the level of control did not exceed that obtained from the standard treatment of 0.4 g 2,4-D ester.
