- Abstract
In order to utilize Litsea cubeba essential oil to achieve green control of potato late blight,25% emulsion in water(EW) prepared by pure plant extract Litsea cubeba essential oil was used to test the inhibitory effect on Phytophthora infestans in laboratory and field, respectively. The results showed that the 1500 and 1800 times dilutions of 25% Litsea cubeba essential oil EW had 98. 2% and 94. 6% inhibition rate on the mycelial growth of P. infestans, and the field control effect of this agentia reached 75. 00%. Therefore, the 25% Litsea cubeba essential oil EW can prevent the damage of P. infestans by inhibiting the growth of mycelia, and achieve green control of potato late blight, which provides a new way to control potato late blight.
