Preventing Decomposition of Agricultural Chemicals by Alkaline Hydrolysis in the Spray Tank

In this publication we describe the alkaline hydrolysis reaction and the conditions under which it occurs, and provide information on the susceptibility of agricultural chemicals commonly used in tree fruit production to this problem. In addition, data are presented on the pH of spray water sources in the major fruit growing areas of New York. Finally, we discuss ways to measure pH, and how to lower the pH of alkaline water to slow or prevent pesticide breakdown in the spray tank
