Banned Spray is a term used to refer to two chemical compounds, ALAR and DDT, that have been banned in many countries due to their harmful effects on the environment. ALAR, or Alarcon, is an agricultural growth regulator that was used to increase the size of fruit and vegetables. DDT, or dichlorodiphenyltrichloroethane, is an insecticide that was used to control pests. Both of these chemicals have been linked to health problems and environmental damage, leading to their ban in many countries.
