• Abstract: We conducted a pyrethrum synergism study for organic control of GWSS that evaluated rosemary oil, or cinnamon oil (as cinnamic aldehyde) as piperonyl butoxide PIP (synergist) substitutes. Pyrethrum, alone or combined with PIP, was not consistent in efficacy against GWSS. Pyrethrum, and pyrethrum with PIP, gave effective GWSS control in a June 2003 trial but not in two September trials (2002, 2003). Efficacy of PIP alone was not significant from controls in any of the trials. No significant synergism occurred between pyrethrum and PIP. Neither Hexacide nor Cinnacure alone controlled GWSS in this study; nor did they synergize pyrethrum.
