In which mixing order should surfactants and penetrants be added?

Surfactants and penetrants are important additives in pesticide formulations that help improve the effectiveness of the active ingredients. When mixing pesticide solutions, adding these ingredients in the correct order can significantly influence the overall efficacy of the treatment.

In the correct mixing order, surfactants and penetrants should be added after the primary ingredients, such as the pesticides and water or carriers, have been combined. This is typically placed in the sixth position of the mixing sequence. Adding surfactants and penetrants later in the mixing process ensures that they can properly disperse and interact with the other components in the spray mix, enhancing their ability to improve wetting, spreading, and penetration of the active ingredients into the target surfaces or pests.

This mixing order is established based on the need to achieve optimal mixing without causing incompatibility or precipitation of other ingredients, and it allows the surfactants and penetrants to function effectively without interfering with the initial mixing of the chemical components.
