Essential oils (EOs) were studied in vitro and in vivo for inhibiting Phytophthora capsici. Mycelial growth of P. capsici was examined on EO-amended media or after exposing it to EO volatiles. The efficacy of EOs was determined by estimating the effective concentration for 50% inhibition of P. capsici mycelial growth (EC50).
The results taken together suggest that oregano, red thyme, and palmarosa EOs may be potential components for integrated management of P. capsici.
