Paraquat is a dangerous substance but only to the user. Used properly it is harmless. On contact with soil it becomes inert and cannot enter the food chain. There is no evidence to support the scare talk one sees here and in other discussions but it is fashionable to be 'green' so now it will be banned here. The only effect will be to make the poor farmers poorer as their crops cannot compete with weeds and food to be more expensive whilst the do gooders sit on the bandwagon and clap their hands. I am all for a cleaner world but this is not the way to go. Banning cars would save a lot more lives and clear up the air but that would inconvenience the rich so won't happen. Alcohol kills countless people yet wil remain a legal chemical. Lets get our priorities right.
