What is a granular formulation in pesticide use?

A granular formulation in pesticide use refers to a dry formulation of pesticides that consists of small, discrete particles. This type of formulation allows for easy application over various surfaces, making it particularly suitable for use in non-crop situations, such as around ponds or other aquatic environments. Granular pesticides can also provide a slow release of the active ingredient, offering extended control over target pests while minimizing the potential for runoff into water sources.

The other options describe different pesticide forms that do not match the characteristics of granular formulations. A liquid pesticide that is diluted with water does not align with the definition of granular because it involves a liquid solution rather than a solid formulation. An ointment-like pesticide for topical application describes a semi-solid formulation typically used for specific surface treatments, not for broad application in aquatic settings. Lastly, a gaseous pesticide solution is not associated with solid particles and is more related to fumigation practices, which do not fall under the granular category. Thus, the definition of granular clearly distinguishes its role in pesticide application.
