What percentage range of active ingredient is typically found in pellets?

The percentage range of active ingredient typically found in herbicide pellets is often between 1% to 15%. This range reflects the common formulation practices for granular herbicides, which are designed to be effective while also being safe and manageable for applicators and the environment. Pellets provide a slow-release mechanism for the active ingredient, which enhances efficacy and minimizes the risk of runoff or leaching.

Formulating herbicides within this percentage range allows for versatility in application rates, depending on the target species and area of application. Lower concentrations help to ensure that the chemical can be applied accurately and that it does not pose undue risk to non-target organisms or potentially harmful effects on the environment. As you move outside of this range, either at lower concentrations or higher than 15%, there tends to be a shift in the formulation dynamics, including reduced effectiveness or increased risk of phytotoxicity.
