In pesticide terminology, what are "pellets" generally used for?

Pellets in pesticide terminology are specifically designed for direct application to the soil. This form allows for precise placement and minimizes drift, ensuring that the active ingredients are delivered directly where they are needed—typically at the root zone of plants. The use of pellets can also promote a slow release of the pesticide into the soil, enhancing effectiveness and reducing the frequency of application.

In contrast, other options refer to different methods of pesticide application. Dusting on plants involves using powdered formulations that can easily spread over leaf surfaces, which is not the function of pellets. Concentrates for dilution refer to liquid formulations that require mixing before use, while liquid sprays are typically used for aerial or tank applications where the pesticide is dissolved in a liquid carrier. Each method has its distinct applications and advantages, but pellets are uniquely suited for soil treatments.
