Phytophthora capsici is a plant oomycete pathogen, which causes many devastating diseases on a broad range of hosts. Zedoary turmeric oil (ZTO) is a kind of natural plant essential oil that has been widely used in pharmaceutical applications. However, the antifungal activity of ZTO against phytopathogens remains unknown. In this study, we found ZTO could inhibit P. capsici growth and development in vitro and in detached cucumber and Nicotiana benthamiana leaves. Besides, ZTO treatment resulted in severe damage to the cell membrane of P. capsici, leading to the leakage of intracellular contents. ZTO also induced a significant increase in relative conductivity, malondialdehyde concentration and glycerol content. Furthermore, we identified 50 volatile organic compounds from ZTO, and uncovered Curcumol, beta-elemene, curdione and curcumenol with strong inhibitory activities against mycelial growth of P. capsici. Overall, our results not only shed new light on the antifungal mechanism of ZTO, but also imply a promising alternative for the control of phytophthora blight caused by P. capsici.
