RootKill Weedkiller 4 x 100 ml Concentrated Sachets, Glyphosate Weed Killer, with 5 Litre Garden Sprayer

It cleared the weeds in one go

The Spray bottle itself is ok, but the weedkiller has been relatively ineffective, mixed as directed, 1 sachet to 1 litre of water, and a week later, almost no effect, one to avoid in my book

Sprayed to recommend amount no affect perfect weather, I've been a farmer and Sprayed 100s of acres of land this product isn't worth the money.

This weedkiller is great but the sprayer leaks air at the top so it doesn't hold pressure it hisses and bubbles from the screw fitting

First time I used it broke within 5 minutes lost pressure. Tried pumping it up but waste of time.
