Application guide:
This product is a commercial grade product sold in a retail format. As such, you only need a miniscule amount per application. First, you need to calibrate your sprayer. Basically you need to work out how much water is used when spraying a certain area. All sprayers and all people spray different so this is different in each case. This guide explains it (see page 2) - in a nutshell, fill your sprayer with water and spray a hard surface like concrete (on the driveway is fine) and work out how much water you use to spray 10m2. Simply then multiply it by 10 to get 100m2.

Proforce Duke label rates are as follows;
For Wintergrass or Rye, label rates are 150g/HA = 1.5g/100m2
For broadleaf control it is 100g/HA = 1g/100m2
For onion weed it is 25g/HA = 1/4g/100m2

The rates seem miniscule but it is because the product is specialised and design for broadacre application.
