Application of guaiacol to tomato yellow leaf curl virus

Abstract

The invention discloses application of guaiacol to tomato yellow leaf curl virus. The application concentration of guaiacol chemical liquid is 50-500 micrograms/mL, and an emulsifier is added into the guaiacol chemical liquid to serve as a surfactant. The guaiacol is used in prevention and treat of the tomato yellow leaf curl virus, has a prevention and treat effect of 50 percent for the tomato yellow leaf curl virus, and has an effect of treating both diseases and insects when used together with chemical pesticide for preventing and treating a virus transmitting mediator bemisia tabaci. Experiments prove that guaiacol can be used for effectively preventing and treating the tomato yellow leaf curl virus.
