What is the approximate size of a granule used in pesticides?

In the context of pesticides, granules are typically designed to allow for efficient application and effective dispersion in soil or on plants. The approximate size of a granule used in pesticides is about the size of a grain of sand. This size allows for proper distribution when applied and aids in minimizing the risk of drift or oversaturation in a localized area, enhancing the efficacy of the pesticide.

Granules that are similar to a grain of rice or a pea would be too large for many application methods, leading to uneven coverage and potentially reducing the effectiveness of the pesticide. Granules as large as a marble would be impractical for most applications as well, as they would not easily incorporate into the soil or adhere to plant surfaces, which could result in lower performance and increased waste. The grain of sand size strikes a balance that supports effective application practices.
