stop the sonar treatment
stop the sonar treatment
We are actively working to stop the permit requested by the Lake St. Catherine Association from the state of Vermont that would allow the use of sonar 1 and sonar Q to be heavily applied in the Little Lake at Lake St. Catherine.
The current plan by the Lake St. Catherine Association is to heavily treat the Little Lake, and to use a new pellet form of Sonar. What would be used is Sonar Q, which dissolves quickly in the water, and then Sonar 1, which is slower to dissolve. It would take several weeks for the Sonar Q pellets to dissolve, which results in longer contact with the weeds. The 2012 plan called for an initial application of about 20 parts per billion in mid-May. Concentrations will be monitored, and then 3-5 weeks later an other treatment would be applied called a booster to keep the concentration steady, with maybe another treatment 4-6 weeks after that.
We need to stop this massive dosing of Little Lake with these pesticides.
Stop the Use of All Toxic Pesticides in Lake St. Catherine
Stop SONAR and Renovate Treatments
Taken from a study by the San Francisco Estuary Institute: (triclopyr) Renovate
• it is listed as a “group D” carcinogen by the U.S. Environmental Protection Agency
(appears to have caused a significant increase in breast cancer for mice and rats during a
two-year exposure test)
• about half a gram will cause “acute toxicity” in a rabbit; a third of a gram will do the
same to a guinea pig.
• although the label doesn’t say so, EPA found it to be slightly toxic to birds in a 2003
• is acutely toxic to juvenile salmon which could imperil their population long term
• a 2003 study by the Pesticide Action Network found that triclopyr is toxic to the tadpoles
of bull frogs, green frogs and leopard frogs
Oregon State University study; “Triclopyr (Renovate) ranges from non-toxic to highly toxic to fish, depending on the species.”
Fluridone (also known as Sonar 1 and Sonar Q) and Renovate have not been allowed for use by the European Commission since 7/25/2003.
Taken from a report by Sarah Little Ph.D., Wellesley, MA Pesticide Awareness Coordinator: “Fluridone (Sonar): 1-Methyl-3-phenyl-5- [3-(trifluoro-methyl) phenyl]-4(1H)- pyridinone Exposure routes: Fluridone is toxic if inhaled, ingested, or absorbed through the skin. Acute toxicity: Fluridone is considered an immediate health hazard. It has low acute toxicity via ingestion: an amount equivalent to a scoop of ice cream administered to each of four kindergarteners would kill two of them (LD50 5000mg/kg). Chronic toxicity includes adverse effects to eyes, liver, kidney, and testicular atrophy. Studies by Dynamac Corportation for the EPA reported fluridone to be a carcinogen. Environmental toxicity: Fluridone is moderately toxic to birds, fish and aquatic invertebrates. Trees and shrubs growing in treated water may develop chlorosis (loss of green pigment).”
Fluridone has harmful breakdown products, including one (n-methyl-formamide, or NMF) which is known to cause cancer. According to the EPA, “Environmental fate data for NMF is not available.”
Two studies by Vermont Fish and Wildlife fisheries biologist Shawn Good, dated April 5th and April 7th 2006, are reviews of the applications made by the Lake St. Catherine Association. In the studies, Shawn Good spells out why further treatments are both harmful and have a track record of failure. Good wrote that both applications for further chemical treatments should be denied. Good said that his research and personal observations show that chemical treatment of milfoil is a waste of money and a threat to game fish populations in the lake. “Pressure by lake associations for quick and immediate control and reductions of Eurasian Watermilfoil likely have played a role in preventing a longer-lasting, ecologically-sound and less expensive biological control program from being fully investigated.”, he writes. – Dennis Jensen, Times Argus, June 11 ‘06
According to the U.S. EPA more than 70 active pesticide ingredients known to cause cancer in animals are allowed for use…. Is this what you want in the lake your children and grandchildren swim in?
