How can excessive pesticide application lead to pesticide movement in water?

  1. By increasing microbial action

  2. By promoting photodegradation

  3. By reducing volatile tendencies

  4. By causing runoff or leaching

The correct answer is: By causing runoff or leaching

Excessive application of pesticides can lead to pesticide movement in water through runoff or leaching. This is because when pesticides are applied in excessive amounts, they are not able to bind fully to the target plants or soil, and excess chemicals are then able to run off into nearby bodies of water or leach into the groundwater. This can have harmful effects on aquatic organisms and can also contaminate drinking water sources. The other options are incorrect because excessive pesticide application does not promote microbial action or photodegradation, and it does not reduce the volatile tendencies of pesticides. These incorrect options may contribute to the breakdown or degradation of pesticides, but they do not specifically lead to pesticide movement in water like runoff or leaching do.
