The Q&A Archives: reuse of mixed insecticide

Question: Is it ok to use a batch of liquid Sevin still in my sprayer from last season?

Answer: The best way to dispose of insecticides is to use them up according to label directions. It's possible that your mixture has degraded while it was stored but it should still be used according to label directions. I'd stir it well to distribute the chemicals so they are adequately suspended in the liquid and then spray. It may not be as effective as a fresh batch, but that's the best way to use it up.
