Which action can help reduce leaching of pesticides into groundwater?

Using the pesticide rate specified on the label is critical for reducing leaching of pesticides into groundwater. Pesticide labels provide scientifically determined rates that account for the specific type of pesticide being used, its effectiveness, and its potential environmental impact. By adhering to these recommended rates, you minimize the risk of applying excess product, which can lead to increased runoff and leaching.

Applying more pesticide than the label recommends not only wastes materials but also raises the risk of the chemical inadvertently entering water systems, as higher concentrations can be more soluble and mobile in soil. Therefore, following the label instructions helps in ensuring that pesticides are used responsibly, thus lowering the potential for contamination of groundwater sources. This practice aligns with integrated pest management principles that promote environmental stewardship.
