Announcing New Backpack Sprayer Calibration Forest Science Fact Sheet

Announcing New Backpack Sprayer Calibration Forest Science Fact Sheet
http://ecosystems.psu.edu/research/centers/private-forests/news/201...
The latest in the series, entitled Backpack Sprayer Calibration Made Easy, provides in-depth practical information on calibrating backpack sprayers for both band applications and spot treatments. The fact sheet was written by Dave Jackson, Penn State Forest Resources Educator, Art Gover, Penn State Wildland Weed Management, and Kimberly Bohn, Penn State Forest Resources Educator.
“Calibration” simply means determining the output of a sprayer so a known amount of spray solution is applied to a given area. Applicators must know this if they wish to apply an herbicide at a specific dosage, for example, ounces or quarts per acre. Failure to calibrate spray equipment can result in misapplication of herbicides, repeat applications, damaged non-target plants, excess costs, as well as environmental concerns.
