The present invention discloses the application of a strawberry essential oil, and the application of the strawberry essential oil in preparing a product for preventing and controlling Phytophthora tobacco. In order to realize the green prevention and control of crop diseases, the present invention selects efficient bactericidal active ingredients from spice plant sources, and uses the mycelial growth rate method and the living plant method to determine the bacteriostatic activity of the essential oil of grass fruit on Phytophthora nicotianae. Strawberry essential oil has a significant inhibitory effect on Phytophthora nicotianae: in the fumigation method, the inhibition efficiency of the strawberry essential oil on Phytophthora nicotiana is 42.3~96.7%; was 60.5%; the essential oil of grass fruit had a significant effect on the growth morphology of Phytophthora nicotianae. The present invention finds that the essential oil has many advantages, such as environmental protection, low cytotoxicity, broad spectrum, and avoiding the generation of bacterial resistance, and is expected to become an environmentally friendly new pesticide for preventing and treating Phytophthora tobacco. |
