Indiana pesticide application records

Office of Indiana State Chemist (OISC) requires applicators for hire, and anyone applying on golf courses, at schools or for community mosquito abatement to keep a record of restricted-use applications, and general-use applications made for hire or at those sites. The rule: 355 IAC 4-4-1; IC 15-16-5. This guide lists what the record must contain, when it is due, how long to keep it, and what SprayDocs checks before the PDF leaves your phone.

Keep it for
At least 2 years from the application.
Who keeps it
Applicators for hire, and anyone applying on golf courses, at schools or for community mosquito abatement.
Official form
None mandated — the rule lists the elements the record must contain. SprayDocs exports its own layout with the citations printed on it.
Filed with the state?
No filing with OISC. A customer may demand a copy within 30 days.
Copies
No standing copy deadline in the rule we reviewed; copies owed on request are described under filing. Federal law still requires a customer copy within 30 days for restricted-use applications.

What the record must contain

The elements below are required on every Indiana record. SprayDocs shows exactly these inputs for a Indiana record and will not produce the PDF while a required one is blank.

Always on the record

Required in every state, including Indiana.

  • Date of the application
  • Firm name, address and phone number
  • Responsible commercial applicator and license number
  • Name of each applicator who made the application
  • Customer name and the address of the treated site
  • Trade name of each product applied
  • Type of site or property treated

Indiana adds

  • Start timeThe time the application began, for each treatment.
  • Stop timeThe time the application ended, for each treatment.
  • Area treatedHow much area was treated (square feet, acres, linear feet…).
  • Amount applied / total mix volumeThe total amount of mix or product applied to the site.
  • Application methodHow the pesticide was applied — ground, aerial, or chemigation.
  • EPA registration numberThe EPA registration number printed on each product label.
  • Mix rate / concentrationThe mix rate or concentration of each product in the tank.
  • Target pestThe pest or purpose each product was applied for.
  • Certification numberThe applicator’s certification number, when the state issues one separately from the license.
  • Business registration numberThe firm’s registration or license number with the state agency.
  • Manufacturer

Also on the SprayDocs record

Not required on every record by the Indiana rule we reviewed, but common on inspection and worth having. SprayDocs shows these inputs and never blocks the PDF over them.

  • Site coordinates (optional)

Who must keep it, and for which jobs

Who: Applicators for hire, and anyone applying on golf courses, at schools or for community mosquito abatement.

Which jobs: Restricted-use applications always; general-use applications when made for hire or at those sites — effectively every lawn-care application.

Is anything filed with the state?

No filing with OISC. A customer may demand a copy within 30 days.

Copies of the record

No standing copy deadline in the rule we reviewed; copies owed on request are described under filing. Federal law still requires a customer copy within 30 days for restricted-use applications.

Restricted-use products in every state: federal law (7 U.S.C. 136i-1) requires commercial applicators to keep the record 2 years and give the customer a copy within 30 days. SprayDocs flags this on any record with a restricted-use line.

What SprayDocs checks before the PDF

Validation runs on your phone as you type. Blocking items stop the export; reminders do not.

  • Every required element above is checked for a blank: 11 state-specific inputs plus the elements common to all states.
  • A stop time before the start time blocks; an application date in the future is flagged.
  • A product marked restricted-use requires its EPA registration number and shows the federal 2-year / 30-day reminder.
  • Text that the PDF fonts cannot print (an emoji, say) is cleaned rather than allowed to blank a field.

Good to know

  • The former 30-day completion window was removed in December 2022; the record is made on the date of the application.

Fill out the Indiana record

SprayDocs opens with exactly the Indiana inputs above, checks them as you type, and produces a PDF (usually one page) laid out around the rule, with the citations printed on it — all on your phone. The app runs in English or Spanish. Filling it out needs no account; a free account downloads the PDF and keeps a synced copy; the Pro plan adds the crew.
