Which method is effective for preventing ground and surface water contamination?

Conservative application of non-persistent pesticides with high adsorption is effective for preventing ground and surface water contamination because this method minimizes the risk of harmful substances leaching into the soil and water systems. Non-persistent pesticides break down quickly in the environment, reducing the chances of long-term residues affecting water quality. Additionally, pesticides with high adsorption will bind tightly to the soil particles, preventing them from being carried away by water runoff or leaching into groundwater.

This method encourages careful application based on actual pest management needs rather than relying on a calendar schedule or excessive application, which could lead to contamination risks. The approach also emphasizes evaluating environmental conditions and selecting products that will mitigate potential impacts on water systems, a key consideration in responsible pesticide use and environmental stewardship.
