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.
