In vitro studies on E. adenophorum oil extracts indicate their potential as a suitable antifungal agent against P. myriotylum. In vivo studies will be necessary to determine its efficacy as a botanical pesticide for the control of root rot in commercially-produced vegetables. The present results clearly demonstrate that E. adenophorum oil extracts significantly reduce decay in artificially inoculated ginger. However, higher concentrations of the oil extracts may be required in the field where pathogen growth may be favored by better nutritional and moisture conditions than those in the laboratory .
