When a nozzle clogs while spraying pesticides, what is the correct action?

1. Blow the nozzle out with your mouth

2. Use a hammer to loosen it

3. Tap it gently against the ground

4. Clear it with a proper cleaning tool

The correct answer is: Clear it with a proper cleaning tool

When a nozzle clogs while spraying pesticides, it is essential to use a proper cleaning tool to clear the obstruction. This action ensures that the nozzle is cleaned effectively without causing damage. Proper cleaning tools are designed specifically for this purpose and can usually deal with different types of clogs without compromising the integrity of the nozzle. Additionally, using these tools helps maintain the correct spray pattern and flow rate, which is vital for the effective application of pesticides. Using your mouth to blow out the nozzle can introduce moisture and contaminants, potentially compromising the pesticide solution and leading to ineffective application. Applying force with a hammer could damage the nozzle or create other issues. Tapping the nozzle against the ground may dislodge some debris but is not a reliable or thorough method for clearing a clog. Therefore, utilizing the appropriate cleaning tool is the best practice to ensure the nozzle functions correctly and the pesticide is applied safely and effectively.
