• Antitranspirants are generally used to reduce the photosynthesis activity in the crops, therefore, their use is limited to save the crops under nurseries only.
  • Antitranspirants are the following types :
    • Growth retardants: Such hormones are reduce shoot growth and increase root growth and also enhance female flower ratio, thus increase the production and resist to drought.
    • Stomata closing type: Such chemicals reduce water loss through stomatal closing.
    • Film farming type: Retard moisture loss due to formation to thin films as physical barrier.
    • Reflecting type: Such materials reflect the radiation and thus reduce leaf temperature and vapour pressure gradient from leaf to atmosphere and ultimately transpiration is reduced.
