Sprayer Calibration

The arsenal against weed and insect pests is ever changing. Links on this page will provide you with tools that can help make the tasks more productive, safer, and more environmentally friendly.

Boom Sprayer Calibration

Calculations for boom sprayer calibration are tedious at best. This Boom Sprayer Calibration Spreadsheet was designed by Ron Patterson, Carbon County Extension Agent to help take the headache out of calibration calculations (for large boom sprayers (21-120 nozzles) download the Large Boom Sprayer Calibration Spreadsheet). There are two worksheets in the spreadsheet. The first contains instructions on how to use the spreadsheet. The second worksheet can be printed so you can record the data collected in the calibration exercise. After the data has been collected you can go back to the second worksheet and enter the data so the computer can do the calculations for you. Be sure to indicate whether you are collecting data in ounces or milliliters and whether your speed measurements are in mhp or 200 foot timed measurement.  Click on the link above to download the spreadsheet and then save it to your own computer for repeated use.


Handcan Sprayer Calibration

Handcan or backpack sprayers are frequently used for spot spraying. The need for calibrating hand-held sprayers is just as great as for large boom sprayers. This

Handcan Sprayer Calibration Spreadsheet

is another  Excel spreadsheet tool designed by Ron Patterson to help with the calculations needed to calibrate and mix pesticides for single-nozzle hand-held sprayers.
