Which of the following actions is NOT part of the recommended storage procedure for spraying equipment?

The action that is NOT part of the recommended storage procedure for spraying equipment is adding pesticide for future use. This practice can lead to several problems, including the degradation of the pesticide as it sits in the tank over time, which can ultimately affect its efficacy for future applications. Storing pesticides in the equipment can also pose risks of chemical reactions, contamination, or leaks that may damage the equipment or harm the environment.

In contrast, rinsing the system before storage, filling the tank with clean water, and storing nozzles in light oil or diesel fuel are all responsible practices aimed at maintaining the integrity and operational efficiency of the equipment. Rinsing removes any residues that could cause clogging or corrosion. Filling the tank with clean water helps to prevent the buildup of residues or crystallization. Storing nozzles in light oil or diesel fuel protects them from corrosion and ensures they are ready for the next use.
