According to an American website the FDA have warned Monsanto that they are considering banning Roundup as the effects are more long lasting than first thought and now there are resistant super weed developing(surprise, surprise).

We have a sprayer, we wrote weedkiller on the outside in very big, permanent, letters to make sure we wouldn't ever use it for anything else by mistake.

We mostly use it on our drive, because the gravel is a wonderful place for seeds to germinate. But also use it on bindweed. We use a cone-shaped attachment which helps make sure the spray doesn't drift sideways. It's like this

so I don't want spray drifting over) ...................


............I'll be dipping the weed into it though, not spraying it round

Another selective way is to don rubber gloves, dip your hand in solution and grab the weed!

No wonder that plants resistant to anything are developing when plants are being bred to be resistant. I'm almost certain I read somewhere about oilseed rape being developed with a resistance to glyphosate so that a whole crop could be sprayed, killing everything apart from the oilseed rape. Very clever some might say, but then how do they kill off the oilseed rape growing in the wrong places because it is already very difficult to erradicate?

AP, I believe that is the case and it was maize that was first developed to be resistant to glyphosate. Seems to be a bit similar to superbugs developing through overuse/misuse of antibiotics. Anyway it will keep the researchers busy developing new products.
