Iowa
The driftable fines comments from the Wilger representative are really, really important. When spraying with a standard flat fan nozzle, think about driftable fines in this way: plan on absolutely zero value being delivered from that % of your spray. So the math looks like this...
$25/acre weed control pass
Standard flat fan nozzle (20% or greater driftable fines)
=$5/acre that you're getting zero value out of. Plus, you're at greater risk to deliver a sub-lethal dose of the chemistry package, encouraging herbicide resistance. I had bookmarked from 2016 a video from WinField agronomists that talked about this in detail, but unfortunately the link no longer works.
