Which of the following is a legal requirement to perform chemigation?

• A. A Chemigation permit
• B. A pesticide applicator license
• C. A water quality permit
• D. No special permit is required

Answer: (A)

Chemigation is applying pesticides through irrigation water, which carries specific safety and environmental risks. Because of that, regulations require a dedicated permit to operate in this way. A chemigation permit confirms you understand and meet the requirements for safe setup and use, including proper injection equipment, backflow prevention, correct calibration, and required recordkeeping. A general pesticide applicator license covers pesticide handling, but chemigation involves a specific process and equipment setup that a standard license alone does not authorize. A water quality permit isn’t the standard requirement for performing chemigation, and saying no special permit is required would overlook the regulatory oversight. So, the legal requirement is a chemigation permit.
