What is the result of using too much pesticide beyond the calibrated amount?

• A. Improved effectiveness
• B. Increased risk of environmental contamination
• C. Reduced health risks for applicators
• D. Enhanced crop yield

Answer: (B)

Using too much pesticide beyond the calibrated amount leads to increased risk of environmental contamination. Overapplication can result in excess chemicals running off into nearby water sources, affecting non-target organisms, such as beneficial insects, aquatic life, and other wildlife. It may also contribute to soil contamination, which can have long-lasting effects on the ecosystem.

Inappropriate quantities can also lead to pesticide residues in food, raising concerns about safety for consumers. Proper calibration is crucial in ensuring that pesticides are applied at effective levels that control pests while minimizing negative impacts on the environment and public health.
