Glyphogan, what ratio water to weed killer?

I have bought a container of Glyphogan to clear an area of gravel but the instructions are to complex for me to be able to work out the ratio of Glyphogan to water. Can anyone help?

 

I guess thats Glyphosate, if it is its probably too late to use it, it needs to be used when the weeds are growing well.
It should give you the ratio of mix on the container.

 

Many thanks. These weeds appear to be protected by a higher being and I am fed up with getting blisters from my hoe so thanks for the advice.
