There are many ways a person can learn about calibration.

  • Contact your local weed coordinator or extension agent.
  • Attend a Private Applicator’s Class in your area.
  • Use a combination of print and video materials available.

The following are some of the print materials available.

MWCA helped to underwrite this short video that demonstrates calibration of equipment.  We have broken it down in to 6 steps.

MSU Extension also has a DVD available for purchase on their website.

MSU announced August 2010:   New Sprayer Calibration Pocketguides are available for Hand Sprayers and for Boom and Broadjet Sprayers. The guides are printed on weather- and tear-proof paper. Author Cecil Tharp, MSU Extension Pesticide Education Specialist, included information about measuring sprayer or nozzle output, correct tank mixing steps, helpful liquid measurement conversions, sample equations and a recommended application rate chart in ounces per acre. The pocketguides are available for 65 cents each.

Please contact your local county weed professionals to obtain the best recommendations for your specific plants and conditions.
