The role of inert components in pesticide preparations - kaolin and overseas pesticide registration requirements

The role of inert components in pesticide formulations

The inert components in the formulation are often various auxiliaries that are intentionally added for a certain purpose:

(1) Additives to improve product performance;

(2) Additives that make the product easier to use;

(3) Additives that help pesticide effective components to be easily dissolved in water;

(4) Additives that help pesticides expand and adhere to plant foliage and soil surfaces;

(5) Additives that help pesticides enter the insect body;

(6) Additives to extend the life of pesticide preparation products.

EPA registration of export pesticide products

Product registration requires first registering the place of manufacture of the product, obtaining the Company Number and the Establishment Number, and then officially registering the product (Pesticide Product registration) and obtaining the product registration number (Reg. Number) after that, state registration is also required before it can be placed on the state market. The registration cycle of EPA pesticide products is long, taking half a year to one year, and some types of products are even as long as two years.

Product registration is the most important and complex step in the entire registration process. The EPA needs to conduct a comprehensive assessment of the composition, use, etc. of the product, so the applicant needs to submit a series of data to the EPA, including residue data, toxicological data, efficacy data, physical and chemical data, exposure related data, environmental affiliation data, etc., to prove the safety of the product.

Inert Ingredient Registration

In addition to the active ingredient, many pesticide products also contain substances called "inert ingredients" or "other ingredients". The EPA not only focuses on the active ingredient of the product, but also has corresponding requirements for the inert ingredient during the product review process, so the applicant needs to register the inert ingredient.
