When using Gentrol, how long can you leave it in the sprayer before you dispose of it?
After you dilute Gentrol with water, it should be used within 24 hours. Also, you should not store pesticides in your sprayer as they will break down the rubber hose, seals and gaskets and could even cause damage to to the tank over time. Only mix what you can use at one time.
