Hi Chris.
I've got 4 hectares so I consider strimming all of it a non starter.
As the new rules apparently don't apply until 26/11, my solution is to get a few 5 litre jugs in which will last a few years.
Just for the hell of it, why don't we fire up a discussion on the pros and cons of glyphosate ?  Many heated discussions already out there on the net but I'm not convinced on the con argument.  Sure, you wouldn't want to drink the stuff or be breathing in the spray but according to the manufacturers, it becomes inert on contact with the ground.  The arguments regarding resistant seed is a whole different subject and not relevant to the likes of us finca maintainers ?
