Worker Protection Standard (WPS)


The Worker Protection Standard (WPS) is a federal regulation issued by U.S. EPA. The WPS applies to growers who own or manage a farm, forest, nursery, or greenhouse where pesticides are used in production of agricultural plants and have one or more of these situations:

  1. Hire or contract for services of agricultural workers who receive compensation and do tasks such as harvesting, weeding or watering.
  2. Operate a business or farm where pesticides are applied by handlers who receive compensation and do tasks related to mixing, loading, transferring or applying pesticides. Click here for a complete list of handlers tasks.
  3. Operate a business where crop advisor tasks are performed. Click here for a complete list of crop advisor tasks.
