    It has to be an air induction Nozzle to get 90% drift reduction for stripe . Ceramic last longer and powders are less inclined to stick to ceramic .

    As far as I remember the IDK"N" is a very similar nozzle that produces a very slightly coarser droplet size that allowed them meet the 90% drift reduction regs in 03 (blue) and 04 (red).
    It is a while since I looked into it.

    Hey. Which of the nozzles will be better for fungicide and insecticide spraying in OSR and wheat? Guardian Air Twin or TeeJet TTJ60?

    Bought a used sprayer in January that's fitted with Hypro Guardian Air 4's. AFAIK 3 bar is the optimum pressure but how low can the pressure be reduced without significantly affecting performance? Would like to get as close as possible to 160 l/ha at 8kph.

    It depends on target, no issue with low pressure if not targeting small weeds or grasses.
    But GAs work better at a higher speed and from 2bars up the coverage will be better.
    10km at 2 bars will be close to what you want and give better performance.

    Thanks. We were used to doing 160 l/ha at 5 bar and 8km with yellow Nozal AFX jets on the last sprayer so 2 bar seems incredibly low. I'm a little wary of letting the boss man away at the breakneck speeds of 10 kph so we might have to settle for reduced acres/tank until I get a set of 2.5s or 3's.
