What is one major risk associated with over-application of pesticides?

Over-application of pesticides poses a significant risk because it can lead to environmental harm. When pesticides are applied in excessive amounts, they can contaminate soil, water, and air, negatively affecting ecosystems and non-target organisms, including beneficial insects, plants, and animals. This can result in issues such as reduced biodiversity, water quality degradation, and harm to human health through exposure or drinking contaminated water.

Additionally, excessive pesticide application can lead to pesticide resistance in pests, which may necessitate even stronger chemicals or more frequent applications in the future, compounding environmental damage and increasing costs for farmers. Understanding this risk is crucial for effective pest management and sustainable agricultural practices.
