If a nozzle clogs while spraying pesticides, what is recommended to clear it?

The most effective method to clear a clogged nozzle is to run water through it. This approach allows for the gentle flushing of debris or pesticide buildups without damaging the nozzle. Water pressure can help to dislodge any blockages and restore the proper flow of the pesticide, ensuring that the application process can continue safely and effectively.

Using your mouth to blow out the nozzle could introduce contaminants and is not a sanitary practice. Additionally, prying the nozzle open with a metal object can damage the nozzle, rendering it ineffective or unusable, while seeking help from a colleague, while practical in some scenarios, does not directly address the immediate need to resolve the clog. Therefore, running water through the nozzle is the recommended and safest method to clear a clog effectively.
