I have been told that microbs should not stand presures higher than 1.5 bar=
s at the nozzle of the sprayer due to shear stress, but the lowest I might =
be able to find here is 5 bars for Orchards Fan Sprayers. What should I do?

Is it best for CT to be applied with high or low volume sprayers?

What would be the ideal nozzle size for CT aplication on orchards ?

Cheers
Joao

  Please, Ken Your system sounds like an answer we all need. I have long w=

a high tension electical line. Unaffected. Bob

    Yes, there is better coverage of all surfaces. And the water pressure
    is about 20 pounds.
    I am not sure about microbe survival. Since I have a microscope now,
    I will use it to test how well the microbes survive after going thru
    the sprayer. I will do a test next week and let you know what I find.
