Instructions for Sample Backpack Pump Calibration Procedure

1) Measure an area 18.5 ft. by 18.5 ft. in the target application area.

2) Spray the measured area uniformly with water only (or water and indicator dye) while recording the precise amount of time required to cover the area.

3) Measure the amount of water applied to the test area by spraying into a container for the same amount of time.

4) The amount of water collected in fluid ounces equals the spray volume in gallons per acre.

5) Refer to herbicide label or appropriate treatment prescription for desired herbicide application rate (i.e. pts. / acre).

6) Calculate amount of herbicide to mix per gal of water.

Example:

Amount herbicide x Gal water - 2 pts herbicide (from label) x 20 gal water (from test)

Acre Acre acre acre

Equals:

Amount Herbicide - 2 pts herbicide = 0.1 pt herbicide x 16 oz/pt = 1.6 oz herbicide Amount Water 20 gal water gal water gal water

Sample ATV/UTV Sprayer Calibration

Pre-calibration Equipment Check:

• Fill sprayer with water and prime the spray system

• Conduct a test operation of the spray system, checking for leaks, worn hoses or nozzles and plugged nozzles

Calibration Exercise:

AREA

1) Mark off a calibration plot of at least 50 feet

• Plot Length = _________ft

2) Measure the effective spray width in feet

• Spray Width = _______ft

3) Calculate calibration plot area

• Plot Length X Boom Width _______ft X _______ft = ________ft2

VOLUME

4) Drive Length of Calibration Plot 3 times (as if spraying) and Record Time in Seconds/Run

• 1st run = _______Seconds, 2nd run = _______Seconds, 3rd run = _______Seconds

Average Time Required to Drive the Plot = __________ Seconds

5) With ATV parked, collect and record sprayer output for the time to drive the plot (the average of 3 times driven)

__________ Ounces per Plot

6) Convert ounces per calibration plot to gallons per plot

__________ Ounces / 128 Ounces/Gallon = __________ Gallons per Plot

VOLUME per AREA (Gallons per acre)

7) Divide the volume sprayed on the plot (Step 6) by the area sprayed (square feet from

Step 3) and then multiply by 43,560 (square feet/acre) to determine gallons per acre:

________ Gallons / __________ Square Feet X 43,5602/acre = __________Gallons per Acre

Sample ATV/UTV Sprayer Calibration Speed Check

INSTRUCTIONS: Run the Test Three Times and Average the Results.
