A few years ago, the Ohio State University Pesticide Safety Education Program put together a list of approved sprayer nozzles for applying pesticides.
This list was recently updated in May 2023 and can be viewed at https://pested.osu.edu/sites/pested/files/imce/ApprovedNozzles2023.pdf.
The list describes the minimum and maximum operating pressures for each sprayer nozzle. Any limitations for specific nozzles are indicated by a footnote on the chart.
