Which of the following describes a proper storage procedure for a spraying system?

The proper storage procedure for a spraying system includes rinsing and cleaning the system after use. This step is crucial because it helps to prevent chemical residue buildup, which can lead to contamination and malfunction in the equipment. Cleaning the system ensures that any pesticide remnants are removed, reducing the risk of chemical reactions or degradation of the product in subsequent uses. Furthermore, proper cleaning avoids cross-contamination of different pesticides that may negatively affect their performance or pose safety risks.

In contrast, filling the tank completely with pesticide before storage can lead to prolonged exposure of the chemical to the environment or potential degradation, and it does not account for necessary maintenance. Storing nozzles in plain water is not advisable as it does not adequately clean them and may allow for microbial growth or corrosion. Leaving chemical residues in the tank can lead to contamination of future applications, equipment damage, and safety hazards. Therefore, rinsing and cleaning the spraying system is the best practice to ensure its longevity and effectiveness.
