True or False: Granules and dust usually contain a high percentage of diluent.

Granules and dust formulations often include a high percentage of diluent, which serves several important functions. A diluent is an inert substance that does not affect the pesticide's efficacy but helps to facilitate application and improve distribution of the active ingredient. In granules, the diluent allows for easier handling and spreading, and in dust formulations, it helps in achieving the right particle size and enhances the ability of the product to adhere to surfaces.

The high percentage of diluent is necessary to ensure that the product can effectively cover the target area rather than being concentrated in one spot. This increases the likelihood of the pesticide coming into contact with pests while minimizing potential harm to non-target species or the environment. The use of diluents is particularly critical in ensuring the safety and effectiveness of these types of pesticide formulations.
