The invention relates to a method for preventing and treating
trialeurodes vaporariorum of chayotes and belongs to the field of
disease control of crops. The method is characterized by comprising theprocesses of carrying out
crop rotation on vegetables, which are not preferred to the
trialeurodes vaporariorum, such as celery and blanched garlic leaves, thoroughly fumigating remnant
insect populations before
seedling raising, cleaning up weeds and stubbles, carrying out
chemical control, carrying out biological control, carrying out
physical control and the like. The method is beneficial to the improvement of
disease resistance of the chayotes, has a very good effect on the
disease prevention,
insect prevention and high yield of the chayotes and is applicable to the control on the
trialeurodes vaporariorum of the chayotes.
