415 ILCS 60/2
Declaration of Purpose: The purpose of this Act is to regulate in the public interest the labeling, distribution, use and application of pesticides as herein defined. It is recognized that pesticides are valuable and necessary to Illinois' agricultural production and to the protection of man and his environment from pests, but it is essential to our general health and welfare that they be regulated to prevent adverse effects on man and his environment. New pesticides and application methods are continually being synthesized or discovered which may be valuable for pest control. However, such pesticides may cause unreasonable adverse effects on the environment or may be injurious to animals or man if not properly used. It is, therefore, deemed necessary to provide for the regulation of pesticides.
