Proper rinsing of an empty pesticide container involves:

The correct technique for rinsing an empty pesticide container involves partially filling the container with water, shaking it, and then draining the mixture into the spray tank. This method ensures that any residual pesticide remaining in the container is effectively captured and applied as part of the pesticide application rather than being discarded. The shaking action helps to dislodge any residues stuck to the container's surfaces, ensuring that they are adequately transferred to the spray tank for use.

This practice is part of proper pesticide container management and helps minimize environmental contamination and pesticide waste. It also aligns with the principles of good agricultural practices, reinforcing responsible use of chemicals in crop production.

Regarding the other options, they are less effective or appropriate methods for rinsing and may not ensure the complete removal of pesticide residues, which can lead to risks of contamination.
