What is leaching in the context of pesticide application?

  1. Pesticide evaporates quickly

  2. Pesticide breaks down and moves into the water

  3. Pesticide effectiveness decreases over time

  4. Pesticide is absorbed by plants

The correct answer is: Pesticide breaks down and moves into the water

Leaching refers to the process by which pesticides, once applied to the soil, dissolve in water and are subsequently transported downward through the soil profile. When it rains or when irrigation occurs, water can percolate through the soil, carrying dissolved pesticides with it. This movement can lead to the pesticides reaching groundwater or other water sources, posing potential risks to the environment. This concept highlights the importance of understanding how pesticides interact with soil and water systems, especially when planning applications to minimize environmental impact. It emphasises that certain factors, such as soil type and moisture levels, can significantly influence the potential for leaching, and thus affect both pesticide efficacy and environmental safety.
