That's a selective weed and feed for lawns......
Not banned by the EU as yet....
.
Only professionals can use it though atm. I can still buy it, but I have to acquire it in a less conventional manner (didn't use to be the case; you always had to wear a safety-suit though and it's only safe to use under certain weather conditions). The variety you find meant for normal lawns isn't as potent. There isn't a good alternative though. I keep track of the acidity of my pastures, use agricultural lime and fertilize in a timely manner, adequately mow etc...
It's related to my struggle with ragwort. Very poisonous when eaten (irritation if you touch it), full of alkaloids, and it's cumulative; once it's in your body you ain't getting it out. Normally they don't eat it since it's bitter, but when it dies they eat it (hence it's of the utmost importance that you're able to buy safe hay etc...). I normally remove ragwort manually with a tool that also removes the roots, but you obviously can't do that if you're producing hay. Oh and if you're removing ragwort occasionally you have a passer-by that claims that you should not remove it since it has pretty yellow flowers and it's very good for certain butterflies. It results in liver-disease (cirhossis etc...) and death, the butterfly will have to find something else to eat.
In short I don't think they will ban similar products (unless a better alternative arises), because it would create very big problems.
