Boom spray/broadcast application


Step 1. Calculate Sprayer Applicaton Rate

You will need - measure tape & measure jug graduated in mLs

Spray width (in metres)
Measure wetted area excluding feathered edges ?SEE MORE

Number of Nozzles ?SEE MORE
Average output per Nozzle (in mLs)
Measure how many mLs collected in 1 minute. 1000mLs = 1L

* Must enter in Millilitres

Spray Calibration

This is the information you will need to use the spray calibration calculator which determines your sprayer application rate:
  • Number of different type of nozzles on your sprayer
  • Nozzle output (the amount of water collected from each nozzle type in mLs per minute - collect water flow from each nozzle type over 60 sec to determine this)
  • Spray width (measure the wetted spray width on the ground to determine this)
The calculator does the rest for you!

Mixing Rate 

Enter the Weed Force Product and rate from the product label or use pre-loaded examples built into the calculator. 

Custom rates can be entered. Simply input your tank size and the calculator does the rest for you!
