Cinnamon oil and myrrh oil were particularly effective against R . solanacearum， with their inhibitory effects intensifying as the concentration increased. At a low concentration of 10μL/mL ，cinnamon oil demonstrated a remarkable ability to reduce the growth of R solanacearum，with aninhibition zone diameter of 2.55 cm.Cinnamon oil and myrrh oil exhibited significant inhibitory effects on the growth of F oxysporum，V. dahliae，and R .solanacearum.Based on these findings，future research shouldfurtheritatetticoblhasoflantetialilsalidatetesultstouhfldalsdrgsety assessment efforts to more effectively enhance strategies for the prevention and control of tobacco diseases.
