ROSELLE, Ill. –Clarke, a global environmental products and services company, was honored at the 2010 U.S. EPA Presidential Green Chemistry Challenge Awards for their new Natular larvicide, which uses the active ingredient spinosad to control mosquito larvae in aquatic habitats. Clarke is recognized for developing novel, patent-pending plaster matrix that releases optimal levels of product during times when mosquitoes breed.
The award recognizes chemical technologies developed by leading researchers and industrial innovators who are making significant contributions to pollution prevention in the United States.
“This award is a wonderful recognition for the hard work of our research and development team, who were given the task of building a more sustainable larvicide from the ground up,” said J. Lyell Clarke, president and CEO of Clarke. “By bringing new chemistries like this to mosquito control, our industry can reduce the pesticide load and reduce toxicity.”
The active ingredient in Natular, spinosad, was discovered and produced by Dow AgroSciences and is in use in over 250 crops in more than 85 countries with additional uses in animal health and pet care. Natular has been categorized as a “Reduced Risk” larvicide by the U.S. EPA. Four formulations have been listed in the OMRI Products List (Organic Materials Review Institute) and can be used in organic production.
“Natular is a next-generation larvicide that has strong potential to reduce the pesticide load in the environment.” said J. Lyell Clarke, President and CEO of Clarke. “It’s prescription larviciding, using the exact amounts of active ingredients needed to control mosquito larvae, at toxicity rates far below other products. We don’t have to sacrifice performance to be environmentally responsible – Natular delivers on both fronts.”
By creating several proprietary tablet formulations with a plaster matrix that insulates and then slowly releases the spinosad molecule, Clarke has made spinosad formulations that can provide control for up to 180 days, the company reports. This matrix is wholly comprised of compounds approved for use by the USDA in production of certified organic products.
Registered for use domestically and abroad, seven commercial formulations of Natular have been created for use in larval control in a range of mosquito-control environments, from catch basins to salt marshes.
