Records kept by commercial applicators are used for clientele purposes or for internal record keeping. Records must also be kept for three years but have 30 days from the application to record.

If providing records to clients applicators need:

-Name/address, date/time

-Target pest

-Site, crop, commodity, or structure

-Pesticide applied

-EPA registraion #

-Dilution and application rate

-Carrier, if not water

-Name of applicator

If providing records for internal recordkeeping applicators need:


-Wind speed, wind direction, temp, rh

-Start/stop time

-WPS notification

How the Worker Protection Standard is Involved...

Any producer that employs individuals must comply with WPS requirements pertaining to personal protective equipment, restricted entry and posting. Both private and commercial applicators must meet the requirements of WPS when pesticide applications are made. For private applicators, they must post information about the field that was treated. This must be posted at the central display for 30 days after the REI expires. Beginning January 2, 2017 the application records must be posted for the 30 days at the central display but must also be retained for 2 years after the REI expires. The records must include:

  • The site or crop treated
  • The location or description of the area treated
  • Application date
  • Application start AND end time
  • EPA registration number
  • Product Name
  • Active ingredient(s)
  • The length of the REI

Commercial applicators must notify the ag establishment of the location, date/time, product name and its active ingerdients, EPA resistration number, REI and any oral or written notices associated with the application.



There is not a required format for record keeping. Applicators can use computer software, paper, the booklets we've provided, or even a smartphone 'app'! As long as all the required elements are met and the records are available upon request, the applicator can choose the format. However, be aware that if you cannot access your records (the computer crashed!), you will be in violation of the Pesticide Applicators' Act. Recordkeeping can benefit applicators in liability protection and insurance claims. It also provides records useful when reviewing your Pest Management Plan, helps with real estate transfers and management decisions, and most importantly, it can provide useful information when treating pesticide exposures.
