Tobacco and Nicotine: They're Good -- As a Pesticide

(Oct. 27, 2010) — Tobacco, used on a small scale as a natural organic pesticide for hundreds of years, is getting new scientific attention as a potential mass-produced alternative to traditional commercial pesticides.
That's the topic of a report in ACS' bi-weekly journal Industrial & Engineering Chemistry Research.
Cedric Briens and colleagues note that concerns about the health risks of tobacco have reduced demand and hurt tobacco farmers in some parts of the world. Scientists are looking for new uses for tobacco. One potential use is as a natural pesticide, due to tobacco's content of toxic nicotine. For centuries, gardeners have used home-made mixtures of tobacco and water as a natural pesticide to kill insect pests. A "green" pesticide industry based on tobacco could provide additional income for farmers, and as well as a new eco-friendly pest-control agent, the scientists say.
They describe a promising way to convert tobacco leaves into pesticides with pyrolysis. That process involves heating tobacco leaves to about 900 degrees Fahrenheit in a vacuum, to produce an unrefined substance called bio-oil. The scientists tested tobacco bio-oil against a wide variety of insect pests, including 11 different fungi, four bacteria, and the Colorado potato beetle, a major agricultural pest that is increasingly resistant to current insecticides. The oil killed all of the beetles and blocked the growth of two types of bacteria and one fungus.
Even after removal of the nicotine, the oil remained a very effective pesticide. Its ability of the oil to block some but not all of the microorganisms suggests that tobacco bio-oil may have additional value as a more selective pesticide than those currently in use, the report indicates.

Environment officials were absent Wednesday when P.E.I. Green Party Leader Sharon Labchuk spread an illegal pesticide on her lawn.
Labchuk invited officials from the Environment Department, and the media, to her house in Millvale.
"I informed them that today at 11 o'clock I intended to break the law, by spreading a product that was illegal under the Pesticide Control Act," said Labchuk.
The pesticide was corn gluten, which Labchuk describes as benign, but can be used to control weeds. She has the support of the U.S. Environmental Protection Agency in that view.
"The substance is common in many food/feed products and in dietary supplements for humans and animals," the EPA's website notes.
"It provides a safer alternative to toxic chemicals commonly used for weed control on lawns."
Labchuk said corn gluten was one of a number of natural pesticides banned under the act.
"My objective here today was to be charged under the Pesticide Control Act, and bring this to court to challenge the law, and to hopefully have the law struck down," she said.
Labchuk said the Green Party will continue to push to get corn gluten and the other products it considers safe off the banned list.
Environment Minister Richard Brown had no comment on Labchuk's actions.

PEI Pesticide Control Act and Corn gluten

No charges laid: PEI government blinks on organic lawn care products ban
Millvale - After banning a number of products commonly used in organic lawn care, it appears the PEI government is backing down said Green Party of PEI leader Sharon Labchuk.
Earlier this year, Minister of Environment Richard Brown banned the sale and use of certain organic lawn care products containing corn gluten, soap and iron – products actively promoted by other provinces and municipalities all over Canada where toxic chemical lawn pesticides are banned. After years of lobbying by Islanders, the PEI government refused to implement the same sweeping pesticide bans that protect Ontario and Quebec residents, and instead banned just one chemical lawn pesticide and many organic products.
Labchuk informed government that she would be violating the Pesticide Control Act today and provided the time and location to the Department of Environment’s Investigation and Enforcement division. With media present, Labchuk applied a corn gluten product purchased in Quebec to her lawn, a violation of the Act subject to a fine ranging from $1000 to $5000. The corn gluten product is illegal to sell and use in PEI. The Department of Environment’s Pesticide Regulatory Inspector failed to show up and so no charges were laid.
“It’s clear the Minister of Environment does not have the nerve to try to enforce these ridiculous laws banning organic lawn care products,” said Labchuk. “And now, with a ban on lawn pesticides coming in Nova Scotia, Islanders need to force the PEI government, kicking and screaming, to once and for all protect citizens and wildlife from these poisons. Premier Ghiz has shown utter contempt for the majority of Islanders who want these chemicals banned.”
Environment Canada identifies PEI as an area with some of the most intensive agricultural pesticide use in Canada. The agriculture and pesticide industries rally against any citizen effort to end the toxic assault and these industries fund election campaigns for both the provincial Liberal and Conservative parties said Labchuk.
