Properly operated air inducted nozzles also minimize drift. Last time I had to spray a buttonweed infested lawn, that was treated with a combination of metsulfuron and Speedzone Southern. Don't let that drift. Air inducted nozzles operated at 40 PSI kept that mix out of the trees and adjacent flower beds.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.

Sell not virtue to purchase wealth, nor Liberty to purchase power.
