Hi Graeme,
We use floodjet nozzles in our sprayer and have
taken all screens out. We feel that forcing the tea thru screens destroys some
of the microbes, actually I don't even turn on the agitator until the end of the
spray - usually the bouncing around keeps things mixed around. We have a
PTO centrifugal pump though. We started with the smallest floodjet nozzles we
could buy because of slow ground speed, but found we had some degradation of
microbes so we switched to a larger size to eliminate that problem. We first
used flat fan nozzles but they plugged immediately - we have had no problems
with the floodjet nozzles plugging.
