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. Pat |

I know Helen and Maynard Michel have had the same lack of results with both marathn and enstarII.... I wonder if they know about pH. K Barrett |

imidocloprid and pH
all pesticides are Ph sensitive
if it is too alkaline you begin to breakdown the molecule there is much writing about this on the net very hard water will also bind up with the pesticide and prevent it from working J7 "K Barrett" wrote in message ...
