Inhibitory Activity of 5 Plant Essential Oils against Plant Pathogenic Fungi
[Aims] Plant essential oils as pesticides have characteristics of safety and various bioactivities. They can overcome the limitations of chemical pesticides and possess exploitation potential. The antifungal activity of 5 plant essential oils against 10 important plant pathogens was studied in this paper to provide basis for the exploitation and application of these essential oils in pesticide field. [Methods] A growth rate method was used for determining the antifungal activity of plant essential oils against pathogens. [Results] Citrvs reticulata and Ageratum conyzoides essential oils had high inhibitory activity against the tested fungi at 1 mL/L, with the inhibition rates of 77.27-100% and 63.54-100% respectively, and with the EC50 values of 0.2316-0.5653 mL/L and 0.0573-0.1943 mL/L, respectively. [Conclusions] C. reticulata and A. conyzoides essential oils exhibit high inhibitory activity against the tested fungi, and possess exploitation and application values in pesticide field.
