How Your Spray Tank Water Can Impact Pesticide Performance

Aaron J. Patton, Ph.D.

You routinely mix water in with pesticides and/or fertilizers at your facility when you care for the turf and may rarely consider the qualities of that water. It can dramatically affect efficacy. Learn from Aaron Patton, Ph.D., more about what happens inside the tank and what the latest research says about enhancing pesticide performance through spray water adjustments. You’ll hear how some herbicide activity is decreased by different cations in the water. Discussion will include an overview of the relationship between product half-life and water pH as well as details on when to consider a water conditioner. Join us to determine if changes might make sense for you.
