What are insecticide formulations commonly used as larvicides that are based on porous carrier materials called?

Insecticide formulations commonly used as larvicides that utilize porous carrier materials are known as granules. Granules are solid particulates that typically contain the active ingredient blended with a neutral carrier material which helps to facilitate dispersal in the environment, particularly in areas like standing water where mosquito larvae are found.

These carrier materials allow the insecticide to be released slowly, providing prolonged effectiveness against larvae in aquatic habitats. The design of granules helps ensure that the active ingredient remains effective over an extended period and is less prone to degradation from environmental factors compared to some liquid formulations. Granules can be applied directly to water bodies or to soil where they dissolve upon contact with moisture, making them particularly suited for larvicidal applications.

In contrast, liquid formulations, aerosols, and emulsions represent different application methods and forms that may not utilize porous carrier materials like granules do. While all these forms have their respective uses in pest management, granules specifically highlight the use of porous carriers incorporated with larvicidal properties.
