It is important to select a nozzle that develops the desired spray pattern and spray volume. The nozzle’s intended use—whether for broadcast application of herbicides or insecticide spraying on row crops—determines the type of nozzle needed. Examine current and future application requirements and be prepared to have several sets of nozzles for a variety of application needs. In general, do not select a nozzle that requires a nozzle screen less than 50 mesh. Nozzles requiring 80–100 mesh screens clog too easily.
Follow the steps below to determine the correct nozzle type and capacity needed.
