My water comes from a well where water is stored in deep lime-rock formations.
Would any fungicide need to be made more acid before application?
Like use this? INDICATE 5 Brandt, pH Indicator, Acidifier, Water Conditioner, Spreader

"...Check the pH of the spray solution, especially when using alkaline well water. While most fungicides are stable over a range of pH values,some fungicides (e.g., Captan, Dithane, Rovral) can degrade under alkaline conditions. For example, the half-life of Captan is 32 hours at pH 5, eight hours at pH 7, and 10 minutes at pH 8..."
