Renovate® OTF* Receives EPA Approval
Carmel, IN - SePRO Corporation will be launching a new tool for the Aquatic Plant Management Industry in 2007, Renovate® OTF* (On-Target Flakes).  SePRO recently received the U.S. EPA registration for this innovative triclopyr formulation, and is currently pursuing state registrations", according to Sam Barrick, Business Leader for SePRO’s Aquatic Plant Management Business.  Renovate OTF is a dry formulation containing 10% triclopyr acid equivalence, and is labeled for control of emersed, submersed and floating aquatic plants in the following aquatic sites: ponds; lakes; reservoirs; marshes; wetlands; impounded rivers, streams and other bodies of water that are quiescent; non-irrigation canals, seasonal irrigation waters and ditches which have little or no continuous outflow.  The use of this dry carrier for triclopyr will not only improve control of Eurasian watermilfoil and other susceptible weeds in shoreline treatments, but has proven very effective in deeper water treatments that are more susceptible to dilution.  The use of Renovate OTF allows for just the bottom portion of the water column to be treated in deeper water (depths exceeding 4 feet) before plants have reached the water surface.  For example, Renovate OTF will be more effective and economical than a Renovate 3 application when treating water milfoil in 8 feet of water, by calculating a concentration prescription based on treating only the bottom 4 feet of water.

"In 2006, SePRO conducted multiple small-scale trials with the Renovate OTF formulation to determine herbicide release and residue profiles, and to evaluate use rates in a system designed to simulate herbicide dilution from a spot treatment”, says Tyler Koschnick, Ph.D., Manager, Aquatic Plant Research at SePRO.  "The properties of Renovate OTF resulted in a quick release of triclopyr to obtain threshold concentrations, followed by a continual release of triclopyr to maintain sufficient exposure time.  Replicated pond trials conducted at the SePRO Research and Technology Campus indicate that approximately 50% of triclopyr is released from the flakes in less than an hour, with the remaining triclopyr released is less than 48 hours”, commented Koschnick.

SePRO’s formulation technologies were incorporated to provide a LOW-ODOR, LOW-DUST granular alternative to the market place.  By utilizing this unique dry flake carrier, the triclopyr can be carried onto the target plants in deeper water and spatially localized where the target plants are growing, holding this very effective herbicide “ON-TARGET”.  Please consult your SePRO Aquatic Specialist if you have questions pertaining to the use of Renovate OTF.
