What is an acceptable way to dispose of waste rinse water (rinsate)?

Using rinsate in future spray applications or diluting it and spraying the mixture on the same crop are both acceptable practices for disposing of rinsate. These methods ensure that the waste water is used in a way that minimizes environmental impact and maximizes the utility of the pesticide without exceeding the application rates considered safe.

When using rinsate in future applications, it's important to note that the amount of rinsate used must be accounted for in the overall pesticide application rate to prevent over-application and potential harm to plants, wildlife, or water sources. This practice allows for an efficient use of resources, aligning with sustainable agricultural practices.

Diluting the rinsate and spraying it on the same crop follows a similar rationale. It effectively reduces the concentration of any residual pesticide that might be harmful if applied at high levels, while still ensuring that the beneficial properties of the pesticide can be realized without exceeding tolerance levels.

In contrast, dumping rinsate in a vacant lot poses significant environmental risks, including contamination of soil and water, and does not adhere to responsible pesticide management practices. By choosing methods that reuse or dilute rinsate, both agricultural effectiveness and environmental protection are prioritized.
