What is the definition of 'Dust' in pesticide terminology?

In pesticide terminology, 'Dust' refers to a formulation that consists of finely ground particles of a pesticide, typically combined with a high amount of inert carrier material. This formulation is designed to allow for easy application and adherence to surfaces where pests may reside. The finely ground nature of the pesticide makes it effective for targeting pests through contact, as the particles can easily settle on their bodies or in their habitats.

High inert carrier content is essential in dust formulations, as it helps ensure that the pesticide can be applied uniformly while minimizing risks to non-target organisms. Other formulations do not share this same characteristic. For instance, a liquid pesticide suspension would not be classified as dust due to its liquid consistency; a volatile pesticide gas, while relevant in pesticide applications, is distinctly different in form and function; and a pesticide mixed with an emulsifying agent describes a different formulation type often used for producing emulsifiable concentrates rather than a dust. This context highlights the specific nature of the 'Dust' definition as distinct and important in the realm of pesticide application.
