Why are stickers used in pesticide formulation?

Stickers are used in pesticide formulations primarily to minimize pesticide loss due to runoff. This means that when pesticides are applied to a surface, such as plant leaves or soil, stickers help ensure that the active ingredient remains in place for a longer period. By improving adherence to the target surface, stickers reduce the likelihood that rain or irrigation will wash away the pesticide before it has a chance to become effective. This is particularly important for effectiveness and efficiency in pest control, as it allows the product to work as intended, providing better results and reducing the need for additional applications.

In contrast, increasing the amount of pesticide applied, enhancing toxicity, or speeding up absorption are not the primary purposes of stickers. Stickers improve the longevity and stability of the pesticide on the target surfaces, leading to more efficient pest management.
