Worn Sprayer Nozzles Can Cost Money A 50-foot sprayer with 20-inch nozzles spacing would have 31 nozzles. Those nozzles can cost anywhere from $1.50 to $4.00 each. Replacing them is going to cost from $46.50 to $124.00. Replacing nozzles costs money, but look at what those nozzles do during the spray season. If that sprayer covers 1,000 acres of broadcast herbicide work in a season, each nozzle will have sprayed about 33 acres. With an average herbicide cost of $10 an acre, each nozzle will have put out $330 worth of pesticide. "A nozzle that is applying 10 percent too much chemical will add $33 to that $330 chemical cost. Take the $33 times the number of nozzles that are over-applying and it adds up pretty fast. Back to Calibration -
