Boom Sprayer Calibration For Pesticide Applications, Richard Beard, Howard M. Deer

All Current Publications

To protect your investment in agricultural pesticides, a boom sprayer should be calibrated at the start of the season and whenever application conditions change. Also, sprayer output should be periodically checked throughout the season to assure proper application rate. Although boom sprayers are calibrated in a variety of ways, each method utilizes the measurements of nozzle flow rate and equipment travel speed.
