Dow Chemical slumps after EPA revokes herbicide's registration

• Citing high toxicity levels for non-target plants, the EPA has revoked the registration of Dow Chemical's (DOW -2.6%) Enlist Duo herbicide.
• Enlist Duo, which targets severe weed resistance (hinders crop production), was approved last month with a series of restrictions. Dow says it's working with the EPA to provide additional assurances for the product.
