There is usually no safe and legal way to dispose of leftover pesticide from professional applications and therefore all of the chemical must be used according to directions on the label. This includes wash water from pesticide equipment washing, which must be used in accordance with the label instructions.
Best Management Practices
- Collect wash water (from both inside and outside the application equipment) and use it as a pesticide in accordance with the label instructions.
- The rinsate may be applied as a pesticide (preferred) or stored for use for the next compatible application.
