And not in a good way. Contaminated manure in Britain has not only killed the vegetables it was meant to nourish, the owners of the allotment plots where it was used cannot replant in the affected soil for a year.
A U.S. company, Dow, is responsible for putting an herbicide on the market, aminopyralid, whose deadly power is strong enough to persevere after having passed through a cows’s digestive system and sat around on a stable floor and in piles for months. It’s killed, damaged, and deformed vegetable crops across Britain, but scientists are not sure if it would be unsafe to eat the veggies. The cows aren’t affected by it, apparently.
The herbicide is useful because it kills weeds without affecting the grass around them. A ban has been called for, but as far as I could research, has not been instituted, though Dow is issuing warnings about the product.
