This is why many herbicides are labeled for use on sod farms and golf courses only. It is more likely that a sod farm or golf course will use a calibrated boom sprayer. Chemlawn nozzles or the adjustable tip on backpack sprayers as what most lawn people use does not meet the standards of accuracy to apply so that injury is minimized and product efficacy is maximized. I use a hand held 3 nozzle boom to apply a set volume on my lawns.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
