Beware Dow Chemical Herbicide Aminopyralid

Beware of manure fertilizers. If they come from factory farms sprayed with the Dow Chemical herbicide/pesticide aminopyralid (found in products Cleanwave, Milestone vm, Forefront r&p, and Milestone, among others) they will be contaminated. Gardeners in Britain are finding that manure from fields sprayed a year ago still contains the toxic chemical.

Dow,, the company with the lying ad tagline, we bring good things to life. In my head I always add "and we kill them." From the people who brought you Agent Orange, another toxic nightmare.

Persistent Herbicide In Compost Destroys UK Gardens - Can It Happen Here?

In today's Observer, Caroline Davies describes how this year British gardeners find their fruits and veggies are stunted, deformed, and dying. The culprit: Dow Chemical's persistent herbicide aminopyralid sprayed on grazing land or fodder. The herbicide stayed in the plants the cattle ate, stayed in the cattle (and horse) poop, stayed in the compost produced from the poop, and came out the other end of the process all ready to kill food crops and home gardens.

Problems with the herbicide emerged late last year, when some commercial potato growers reported damaged crops.

[T]he herbicide has now entered the food chain. Those affected are demanding an investigation and a ban on the product. They say they have been given no definitive answer as to whether other produce on their gardens and allotments is safe to eat.

It appears that the contamination came from grass treated 12 months ago. Experts say the grass was probably made into silage, then fed to cattle during the winter months. The herbicide remained present in the silage, passed through the animal and into manure that was later sold. Horses fed on hay that had been treated could also be a channel.

It can't happen here?

Well, the EPA has licensed aminopyralid in several products used in the US: Cleanwave, Milestone vm, Forefront r&p, and Milestone.

Gardeners across Britain are reaping a bitter harvest of rotten potatoes, withered salads and deformed tomatoes after an industrial herbicide tainted their soil. Caroline Davies reports on how the food chain became contaminated and talks to the angry allotment owners whose plots have been destroyed
