"So think of those gardeners a few years ago whose plants thrived for a while, then suddenly stopped growing and curled up like arabesque scrollwork. At first, no one knew what was happening. But gradually the syndrome was linked to residues of a new, hormone-mimicking pesticide manufactured by our old friends Dow Chemical, which was first approved in this country in 2005. It’s called aminopyralid. It is used by farmers to kill broad-leaved weeds growing in fields of grass. It locks onto the cellulose in the plants, passes through the guts of the animals that eat them, and retains its potency in their manure, sometimes for two or three years or more." - George Monbiot, Has Beans, monbiot.com, 15 July 2011.
