What is the chemigation rule?

• A. Requires a separate chemigation permit
• B. Applies only to irrigation systems using surface water
• C. Compliance is voluntary
• D. Must be on label

Answer: (D)

Chemigation is governed by the product label. You may inject a pesticide into irrigation water only if the label explicitly permits chemigation. The label tells you whether chemigation is allowed, plus the approved method, rates, timing, and safety requirements. Because labels are legal directions, you must follow them exactly—there is no separate permit and you cannot rely on compliance being voluntary. If a product isn’t labeled for chemigation, you may not apply it through an irrigation system. When a product is labeled for chemigation, you still must adhere to all label instructions, including equipment setup and safety measures like backflow protection and proper injection practices.
