True or False: Granules and dusts usually contain high percentages of diluent.

Granules and dusts often contain high percentages of diluent because they are formulated to facilitate application and improve distribution over the target areas. In the case of granules, a large portion of the product consists of inert ingredients or carriers that help to deliver the active ingredients effectively when the granules break down or dissolve in the environment. For dusts, diluents also play a crucial role in ensuring that the particles are the right size for effective application and that they can move through the applicator without clogging.

The use of diluents in both forms of pesticide helps to reduce the concentration of the active ingredient to safe levels for application, enhance the pesticide's adherence to surfaces, and improve the overall efficacy of the product while minimizing potential risks to non-target organisms and the environment. Therefore, stating that granules and dusts usually contain high percentages of diluent is accurate and reflects their common characteristics in pesticide formulations.
