What type of formulation is used to deliver active ingredients to targets in gaseous form?

Fumigants are a specific type of pesticide formulation designed to deliver active ingredients in a gaseous state. This form is particularly effective for penetrating soil, structures, and stored products, allowing the gaseous molecules to diffuse and spread to target organisms, such as pests or pathogens. The gaseous state enables these chemicals to reach difficult areas that might be inaccessible to solid or liquid formulations, ensuring more comprehensive pest control.

In contrast, microencapsulated pesticides involve solid formulations that release the active ingredients over time but do not achieve a gaseous state. Pesticide-fertilizer combinations aim to provide nutrition alongside pest control but operate primarily in solid or liquid forms. Animal systemics are formulations designed to be absorbed by plants or animals and thus do not deliver their active ingredients in a gaseous form either. Therefore, fumigants stand out as the only option that effectively delivers active ingredients to targets in a vaporized state.
