Sprayer Nozzles

People who apply their own crop protectants should be looking more closely than ever at nozzle selection.  There are plenty of reasons to abandon those flat fan nozzles.

• Different materials call for different nozzles.  Be sure to check your label.
• Be sure to calibrate your spayer
• Use nozzle shutoffs and guidance to avoid overlap
