The toxic weedkiller paraquat, which is produced by Swiss agrochemicals giant Syngenta, has been banned by a European Union court for not meeting health standards...Campaigners say many workers and farmers exposed on a regular basis to paraquat suffer serious health problems, adding that its high toxicity can lead to death...Responding to the ruling, Syngenta, which was not directly involved in the legal action, said it was surprised by the "unprecedented decision" to annul the 2003 directive. The company said the original decision by the commission to clear paraquat had been preceded by a full scientific review.
