- If you are a farmer then you can raise barrier cereal crops around the field to prevent the vector from entering your farm land.
- If you practice inorganic methods of control then you can spray Imidachloprid 0.05% or Dimethoate 0.05% in the interval of every 15, 25, 45 days after transplantation to control the spread of whitefly that carry this hazardous disease.
