Water quality and sprayers…

what every

should know

By Tami Van Gaal, CEA Division Leader
Several water quality factors can have a tremendous impact on sprayer performance. The
first thing to consider is the pH of the spray solution. Spray water pH strongly impacts many
chemicals by a process called alkaline hydrolysis, which is a fancy way of saying that a
chemical change occurs when the pH is above a certain level. This change, or breakdown,
can reduce the efficacy of the product, and the pH at which hydrolysis happens is specific
to each chemical. For example, the optimum pH for Triathlon is 4-5, while the optimum pH
for ZertoTol 2.0 is 5-7.
Two immediate questions should come to mind. First, where can I get all the optimum pH
information in one place? And, second, what’s an easy way to make sure my spray solution
is at the proper pH? Fortunately, the Griffin team has you covered for both questions. Our
technical team, GGSPro, maintains a bulletin that lists the optimum spray water pH for all
