Like with most liquid concentrates, we recommend that you only mix when you are ready to spray. Crossbow should be used within 24 hours of mixing. You should then rinse your equipment throuoghly. This will also prevent any damage in the long run to your sprayer. The storage shelf life of Crossbow Herbicide is 3-5 years if stored in a area that does not allow the product to freeze or reach over 80 degrees.
