Apply Grassmate at 10-12L/ha for brush species.  In pasture weeds such as Ragwort, fennel, nettles, inkweed, thistles, and a wide range of broadleaf weeds are controlled. 

For spot spraying, the knapsack spray rate is 6ml/L of water.  Note this is just for spot spraying and should not be used at this rate for lawns.

For weed control in turf or lawns, this needs to be applied at the rate of 2L/ ha equivalent.  This is the same a 20ml/100m2.  This level is very dependent upon how heavily or lightly you spray so you really need to test how much coverage you get from your sprayer.
