The invention discloses a prevention and control method for tomato chlorosis virus disease. Tomatoes are cultivated in a sunlight greenhouse according to sizes, the large row spacing is 80cm, and thesmall row spacing is 60cm; trapping plants are transplanted before field planting of the tomatoes in 15-20 days, a row of the trapping plants is planted in the middle of small rows of field planting rows, and the plant spacing is 25 cm; substrate discs containing carbonized rice husks are used for the trapping plants to culture seedlings, carbonized rice husks are applied to planting pits, and thiamethoxam solution is used for disc dipping and root irrigation; before the trapping plants are transplanted, a 40-mesh insecticidal protective net is used for closing vents of the sunlight greenhouse. The prevention and control method can effectively reduce the incidence of tomato chlorosis viruses on the premise of greatly reducing chemical pesticide dosage and achieving non-contact chemical control of main crops, and the incidence of the chlorosis viruses in susceptible tomato varieties can generally be controlled within 4%.
