Environmentalists are up in arms over a proposal by Florida drug enforcement officials to wipe out marijuana plants with a bioherbicide, a soil-borne fungus. The state Agriculture and Environmental Protection departments have given approval for tests of the fungus in a quarantine lab. Enviros worry that the plant-killing fungus could mutate and cause diseases in crops and wild plants. In Peru, angry farmers recently accused the U.S. of using a soil fungus to destroy coca plants and said the fungus has spread to banana, tangerine, yucca, and other crops.
