Glyphosate is very cheap for grass between paving slabs - you need
only half strength and one application, just on the grass.

I agree very much with the above- but be carefull to shield any surrounding
grass/plants. Glyphosate is" soaked up" by the leaves and is best applied on
a dry sunny day when plants are growing well, and it works really well on
grass.

You don't have to pay for the branded names as you've found out already and
it is usually cheaper to buy stuff that you have to dilute yourself- try
sunday markets for best prices.I've read it has a shelf life of 2-3 years!
