What is the characteristic of dust formulations regarding their active ingredient concentration and carrier materials?

Dust formulations are characterized by having a low percentage of active ingredients (AI) combined with inert dry carriers. This is because dusts are designed to provide a more even distribution of the pesticide over a target area, making them effective for applications where minimal moisture is present. The inert dry carriers serve multiple roles, including ensuring the pesticide adheres to surfaces and becomes airborne when disturbed, allowing for effective pest control.

The low concentration of active ingredients in dusts makes them practical for applications where high volumes of pesticide are not necessary or could be detrimental. This distinction is important when comparing dust formulations to other types of pesticide formulations, such as liquids, which typically have higher concentrations of active ingredients and use liquid carriers. Dusts are particularly useful in places that require precision or where moisture-based solutions could be less effective.
