Which statement about pesticide rinsates is true?

• A. Rinsates containing strong cleaning agents may be reused in pesticide mixtures.
• B. The amount of pesticide in the rinsate plus the amount of pesticide product in the new mixture may exceed the label rate for the target site.
• C. Rinsates should always be disposed of at the site where produced.
• D. Rinsates may be applied to labeled target sites at or below labeled rates.

Answer: (D)

Rinsates are the water used to rinse spray equipment and carry some pesticide residue. The important rule is to handle this rinsate exactly as the label directs. The only statement that fits is that rinsates may be applied to labeled target sites at or below the labeled rates. This means you can use the rinsate to apply pesticide on a site that the product label permits, but you must not exceed the rate shown on the label. Following the label protects crops, workers, and the environment and keeps you compliant with pesticide regulations.

Rinsates containing strong cleaning agents shouldn’t be reused in new pesticide mixtures, because the cleaners and residues can cause chemical incompatibilities or alter the product, which labels do not authorize. Rinsates are not automatically disposable only at the production site; disposal options depend on label directions and local regulations, and exceeding the labeled rate by adding rinsate to a new mix is not allowed.
