SePRO Corporation Introduces Galleon* SC Aquatic Herbicide

Carmel, IN – A new tool for the selective control of emergent, floating and submersed aquatic weeds like hydrilla, Eurasian watermilfoil, water hyacinth, water lettuce, salvinia and duckweed, has received its Federal EPA registration for nationwide use.  SePRO Corporation announced that Galleon SC received federal registration on July 17, 2007.  SePRO began extensive evaluations of this reduced risk aquatic herbicide in 2001 and initiated the required regulatory studies in 2004.  SePRO has now begun the process of seeking individual state registrations.  SePRO expects to be able to provide Galleon SC to water resource managers throughout the United States yet this fall and in time for the entire 2008 use season.

Galleon SC is an excellent tool for management of freshwater aquatic vegetation in: ponds, lakes reservoirs, marshes, wetlands, bayous, drainage ditches, non-irrigation canals and other quiescent bodies of water; shoreline and riparian areas for the control of floating and emergent plant species; and also for the dewatered areas of quiescent bodies of water.  Galleon SC is the first herbicide in its class (ALS-inhibitor) to receive a nationwide EPA registration for submersed weed control.  Galleon SC's hydrilla killing activity is similar to that of the industry leading Sonar* brand.  Galleon SC is slow acting and selective to the targeted invasive species, providing negligible risks to many non-target native species.  Galleon SC is expected to become an integral part of herbicide rotation programs for hydrilla management as water managers work to fight the development and spread of herbicide resistance among the few available hydrilla herbicide options.           

Research with Galleon SC was conducted by SePRO at its own Research and Technology Campus (SRTC) in Whitakers, NC and in various field sites across the country, as well as by cooperators like the USACE ERDC Environmental Laboratory, University of Florida, Purdue University, North Carolina State University, Mississippi State University and Washington State University.  This extensive field and laboratory research has established an excellent understanding of efficacy on a wide range of target and non-target species when using Galleon SC.  The use of this product has demonstrated fairly specific efficacy on two troublesome invasive plants, hydrilla and water hyacinth, when used as an in-water application.  In addition, Galleon SC is effective on multiple nuisance species of floating leaf plants when sprayed on the leaf surface at rates up to 5.6 ounces/acre.

Galleon SC is the industry’s newest advancement in aquatic plant management, and this new chemistry is showing excellent promise when used alone or in combination with other aquatic plant management tools. 

“We are very pleased with the EPA registration of this product and the continued progress being made at SePRO in the further development of such a promising compound,” said Dr. Steve Cockreham, Vice President of Research and Development for SePRO Corporation. “Galleon SC meets and exceeds many of the parameters set by SePRO as desired characteristics for a high performance systemic aquatic herbicide.  As a leader in the U.S. Aquatic Plant Management Industry, one of SePRO’s missions has been to continue to Advance the Science of Aquatic Plant Management.  The addition of Galleon SC to our industry’s tool box will definitely provide another positive contribution.”
