Quarantine is the group of measures taken by the state to prevent the introduction and spread of the pests, diseases, and weeds presenting the greatest danger to agriculture. In Indo-Pak subcontinent, the plant quarantine work was formally initiated with promulgation of Destructive Insect and Pests Act, 1914.
