§ 12821 Pesticide Registration Requirements

This law says anyone who wants a pesticide registration must tell the state every brand and type they’ll sell, the exact name and percent of each active ingredient, and the total percent of all inert (non‑active) ingredients; the director can also ask for the full chemical formula.

Key Takeaways

  • •You must list every brand, trademark, and type of pesticide you plan to sell.
  • •Give the exact name and percentage of each active ingredient.
  • •Report the total percentage of inert ingredients (must equal 100% minus the actives).
  • •The director can ask you to provide the full chemical formula if needed.

Example

A company wants to register a new garden insecticide called "BugBuster".

The company must file a statement that says the brand is BugBuster, the active ingredient is pyrethrin at 25%, and that the inert ingredients make up the remaining 75%; later the director could ask for the complete recipe of BugBuster.

How to Calculate

Inert % = 100% – (Sum of all active ingredient percentages)

  1. Add together the percentages of every active ingredient listed.
  2. Subtract that total from 100%.
  3. The result is the total percentage of inert ingredients you must report.

BugBuster contains two actives: pyrethrin 25% and piperonyl butoxide 5%.

Result: Inert % = 100 – (25 + 5) = 70% inert ingredients
