imidocloprid and pH
This quarter's 'Phalaenopsis' has an interesting quote from Allen of Gold
Country
"Tristar is a product that is similar to Marathon or Merit. It's an
insecticide that works well on scale or mealy bug. But if you don't bring
the pH down to 6.2, it's not very effective. And the nice thing is that
they don't tell you that on the label. It is available on line."
Maybe this is why I have had mixed results with Marathon. I make and use
different waters. Unless the label has water requirements I mix chemicals
with whatever water is in the tanks.
