Inert Carriers and Fillers

Inert Carriers and Fillers Imerys minerals make excellent inert carriers, fillers, and anti-caking additives for agricultural chemicals

Imerys calcium carbonate, diatomaceous earth, kaolin, perlite, and synthetic silicates make excellent functional carriers in agricultural products due to their high porosity and chemical inertness. 

Inert carriers used in pesticide formulations are regulated the same as active ingredients and need to be on an ‘approved’ list before use. Pesticide  formulations are registered with government authorities as Confidential Statement of Formula (CSF), stating specific ingredients. 


Imerys minerals are particularly well suited as carriers used in the following agrochemicals:

  • Biocides
  • Biostimulants
  • Flea and tick powders
  • Fungicides
  • Herbicides
  • Inoculants
  • Insecticides
  • Micro organisms
  • Seed treatments

Imerys minerals enable formulators to reduce costs by extending expensive chemicals and improving active ingredient dispersion and flow.  

In general, most inerts are not inert!  Product selection is based on the chemistry of the active ingredient and end-application. They are available in a wide range of particle sizes and chemistries to meet specific formulation requirements.
