Which of the following is allowed when using pesticides according to label directions?

When using pesticides, adhering to label directions is crucial for both safety and effectiveness. Option C is correct because lowering the application rate may be permissible under certain conditions as long as it does not compromise the product’s effectiveness or violate legal regulations. Some pesticide labels provide guidelines indicating that adjustments can be made based on specific environmental conditions or target pest populations, provided the minimum effective dosage is still maintained.

In contrast, other choices imply practices that can lead to misuse and potential legal or safety issues. Mixing pesticides with other chemicals not specified on the label can lead to chemical reactions that may render the pesticide ineffective or harmful. Similarly, applying pesticides without the required protective equipment can pose health risks to the applicator, as well as to others nearby. Increasing the application rate is often discouraged unless explicitly stated on the label, as it can lead to environmental contamination, resistance in pest populations, and potential and legal violations.
