Subject: RE: spray tips to use when "breezy"


Just as a rough idea.

At 12mph wind, drift of any tip is effectively going to DOUBLE.
At 20mph, I'd be reckoning that it'd be over tripling.

For a conventional flat fan -04 nozzle, you'd be talking like around 24% driftable fines at 40PSI in ideal conditions.
So, 12mph, that'd pretty well turn into 48% of your spray not going where you want it to go (evaporating, moving 5ft/50ft/500ft off target).
At 20mph, might be closer to 70% of your spray relying on the wind to bring it into the crop, so less consistency.

Again, I totally get real life conditions and living in a wind tunnel waiting for an ideal spray day, but at least with a bit of a reference to what you realistic drift might be, it might give some support as to which nozzle you'd be going towards to ensure you can spray confidently in the real life conditions that you have to deal with.

For a handful of the coops, they might be using a CRAZY ULTRA COARSE nozzle, but to get your drift down into the realm of <3%, you are usually taking a like 50-60% cut in coverage compared to a proper nozzle in proper wind speeds. So, not ideal for coverage or weed resistance if you have fields with some known chem resistance.

Lemme know if you have any questions,
