Application of Kaolin @ 5% reduces transpiration losses, this act as

Solution

Stomatal closing type: They reduce the water loss by closing the stomata. Examples: Phenyl mercuric acetate (PMA @ 10-4), Atrazine, and C02 Film-forming: Check transpirational loss due to the formation of thin-film which acts as a physical barrier. • Examples: Mobileaf, Hexadecanol, Silicone, oils, and waxes. Reflecting type: These chemicals reflect the radiation and reduce the temperature. Examples: Kaolin @ 5% Growth retardants: These chemicals reduce the shoot growth and increases the root growth and enable to resist drought. Example: Cycocel (CCC)
