Which forms do dry formulations of pesticides take?

Dry formulations of pesticides primarily take the form of dust and granules. Dusts are very fine formulations designed to be applied in a way that allows the active ingredient to adhere to surfaces or be inhaled by pests. They typically require careful application techniques to ensure effectiveness without causing excessive drift or exposure to non-target organisms.

Granules, on the other hand, consist of larger particles that can be spread over a targeted area, allowing for slow release of the active ingredient into the environment. These formulations are particularly useful for controlling pests in soil or on lawns and gardens, as they can provide a longer-lasting effect compared to other formulations.

The other options listed do not represent dry formulations. Aerosols and liquids are typically wet formulations, while gels and powders also do not encompass the common dry forms predominantly used in pest control. Liquids and emulsions likewise pertain to formulations that are not dry.
