What is referred to as chemigation?

Chemigation is specifically defined as the application of pesticides through irrigation systems. This method allows for the efficient distribution of pesticides to crops, ensuring that the targeted areas receive the treatment directly through the water that irrigates the fields. The integration of pesticides into irrigation not only saves time but also minimizes the labor required for manual application. This technique can enhance the effectiveness of pest management by ensuring consistent application and uniform coverage.

The other options relate to agricultural practices but do not accurately describe chemigation. For example, adding nutrients to irrigation systems pertains to fertilization rather than pest control. Storing pesticides safely refers to proper handling and storage practices, which is crucial for safety and regulatory compliance but is distinct from the application method itself. Lastly, the regulation of pesticides in water supplies involves oversight to prevent contamination and is separate from the process of delivering pesticides to crops through irrigation.
