Roundup as sold in garden centres is a mere fraction of the strength of that supplied to farmers (which is intended to be diluted before use, but we use it 'straight out of the container' for injection).

I imagine that that makes a big difference, but, I admit that treating an acre of the weed would be tiring (as well as being expensive).
