Preface

Rotenone was first used as a piscicide in the United States and Canada in the 1930s. Prior to the passage of the amendment to the Federal Insecticide, Rodenticide and Fungicide Act of 1970, rotenone and other pesticides were regulated in the United States by the U. S. Department of Agriculture, and rotenone was first registered in 1947. In 1970, pesticides became regulated by the U.S. Environmental Protection Agency. Registration now requires physical, chemical, public health and environmental data to demonstrate effectiveness at appropriate concentrations of the intended use and to allow for assessments of risk-estimating the impacts to human health and the environment. In 1988, all pesticides, including rotenone, registered before November 1, 1984 were put into a reregistration process requiring the generation of data to support continued registration. After the necessary risk assessments for rotenone were completed, the U.S. Environmental Protection Agency issued the Reregistration Eligibility Decision in March 2007 (EPA 738-R-07-005). As a condition of the reregistration requirements, a manual was requested by EPA that contained procedures, specifically on how to minimize nontarget exposure and effects and to provide guidance on the new, reasonably complex label use conditions. With the approved reregistration came several significant technical changes in how rotenone will be used as a tool in fish management. These changes are incorporated into Standard Operating Procedures (SOPs) in this manual that provide guidance on how to comply with the label, and use rotenone in a safe and effective manner. Many of the SOPs in the manual (SOPs 5, 6, 7, 8, 9, 10, 13 and 16) are referenced on the label and must be followed to the extent dictated by the wording. The manual contains other SOPs which, even though considered largely advisory, complement the safe and effective use of rotenone and should be understood and followed. The manual also provides guidance on project planning procedures needed for rotenone use. The American Fisheries Society’s Fish Management Chemicals Subcommittee, in cooperation with the Rotenone Task Force (coalition of rotenone registrants) and U.S. Environmental Protection Agency developed the manual.

The manual contains four sections beginning with an introduction that orients the reader to a brief history of rotenone registration, new label directions, use as a fishery management tool, information on formulations and environmental fate, public health and concerns, and an overview of the manual structure. The second section provides general guidance on rotenone project planning procedures and how the Standard Operating Procedures are used in successful planning. The third section contains Standard Operating Procedures that limit rotenone exposure and effects and compliment the label. The fourth and final section provides a complete list of references. Detailed instruction on rotenone application techniques, hands-on experience with application equipment, matching rotenone formulations to specific waters and examples of successful planning are provided in a week-long course given by the Fish Management Chemicals Subcommittee. Information on current piscicide course scheduling can be found at the American Fisheries Society’s website www.fisheries.org/units/rotenone/.
