Product Registration
The Louisiana Department of Agriculture and Forestry (LDAF) pesticide/pharmaceutical registration requirements (including Section 3, Section 25(b) and pharmaceutical products) are as follows:

  1. Submission of a registration application through the Online Pesticide/Pharmaceutical Registration Portal (LAPlants) or by submitting a paper registration application by mail. The preferred method is through the online registration portal which allows for electronic payments (credit cards and e-checks). The following document provides instructions on how to logon and register for the online registration portal and how to submit applications by mail if the online registration portal is not used: Instructions for Online and Mail-in Registration Applications. (Pesticide Registration Office contact information: phone: 225-925-3789 and email:,
  2. The fee ($400.00 per product per year)
  3. An electronic (PDF) copy of the product label, and
  4. An electronic (PDF) copy of the product SDS (not required for Pharmaceuticals)

LDAF does not require a copy of the EPA stamped approved label or a copy of the Confidential Statement of Formula (CSF).

The LDAF pesticide registration period is a calendar year, January 1 – December 31. The registration fee is not pro-rated for a partial year’s registration. The $400 fee is required regardless of the time of year the pesticide registration application is submitted.

Each pesticide with a unique United States Environmental Protection Agency pesticide registration number (EPA Reg. No.) or a unique brand name must be registered. Accordingly, alternate brand names and distributor products are required to be registered. However, products where the variations in labels do not list substantive changes, such as, but not limited to: fragrances, colors, etc., require only a single registration. In such cases, write (Various Fragrances), etc. after the Product Name and submit one registration.

LDAF does not require registration of pesticide spray adjuvants. Kits and co-packs are not required to be registered as long as the pesticide(s) in the kit or co-pack are registered with the LDAF.

You can get a copy of the label and/or SDS of LDAF registered products by searching our database at Louisiana Pesticide Registration Search.
