This is a Tampa Tribune editorial. A RISKY WAY TO FIGHT MARIJUANA The head of Florida's Office of Drug Control proposes an innovative way to sabotage marijuana growers. Jim McDonough hopes to unleash a marijuana-killing fungus that would wipe out the illegal crop. Pot growers often hide the plant among corn or other legal crops or plant the marijuana far back in remote swamps. Searches for marijuana fields are costly, time-consuming and often futile. The fungus, McDonough told New York Times writer Rick Bragg, could be applied to the soil in suspected areas and would cause disease in any marijuana that was grown there. The growers would find themselves somewhat like citrus growers whose groves are afflicted with canker - only they could not call state agricultural officials for help. It's a nifty, economical plan, and it is easy to see why it would be embraced by McDonough, who worked for White House drug czar Barry McCaffrey before being appointed to the state job by Gov. Jeb Bush. Nearly half the marijuana confiscated in the nation is captured in Florida. Despite this, McDonough's plan represents a grave threat to the state's environment and agriculture industry and should be treated with extreme caution. Florida, more than most states, has suffered great harm from exotic species that we're promoted as some natural miracle worker. Once introduced into the state's warm, semitropical climate, many of these aliens spread wildly, causing unforeseen havoc. The water-gulping melaleuca tree, for instance, was imported from Australia to dry up marshlands. It now marches across the South Florida landscape like an invading army. It has claimed some 500,000 acres from north of Lake Okeechobee south to Florida Bay, including huge stretches of the Everglades. The tree grows in thick stands virtually barren of native wildlife. Likewise, the Brazilian pepper was introduced as an evergreen shrub. Raccoons, opossums and birds distributed its seeds, and it now infests 800,000 acres from north of Lake Okeechobee to the Everglades. It creates dense forests that displace native plants and animals. Australian pine trees were planted to form windbreaks on islands and around fields, roads and canals. The trees have overrun barrier islands along both the Atlantic and Gulf coasts, threatening endangered sea turtle and American crocodile nesting habitats. Dozens of other exotic plants and animals, including kudzu, walking catfish, hydrilla and water hyacinths, have proved to be costly headaches for the people of Florida. It is particularly worrisome that the biologically engineered fungus could end up attacking plants other than marijuana. State Department of Environmental Protection chief David Struhs warned McDonough in a recent letter that the sort of fungus that would be used to attack the marijuana "is capable of evolving rapidly. ... It is difficult, if not impossible, to control the spread of Fusarium species." Struhs said a mutated fungus could cause disease in other crops, including tomatoes, corn, flowers and vines. Officials with the Montana company that is producing the fungus stressed it will be engineered to specifically attack plants like marijuana and will be harmless to other vegetation. But Florida has heard such claims before. This sort of fungus is active in warm soils, where it can remain for years. Florida, as Struhs says, would provide the idea conditions for it to mutate. So, given Florida's painful history with introduced species, relying on foreign agents to combat marijuana doesn't look to be the smartest idea. The state should be exceedingly cautious. McDonough would be wise to find ways to fight drugs that will not require Florida to gamble its natural resources or its agricultural industry. - --- MAP posted-by: manemez j lovitto
