Registration decision statementFootnote 1 for 98Sumithrin

Health Canada’s Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is granting registration for the sale and use of S1-183 Technical Grade, containing the technical grade active ingredient 98Sumithrin, and the manufacturing concentrate MGK 3145 MUP and the end-use product MGK Formula 31451, containing the active ingredients 98Sumithrin and N-octyl bicycloheptene dicarboximide (MGK-264). MGK Formula 31451 is a pressurized spray that is applied indoors as a crack-and-crevice and spot treatment to furniture, including mattresses, to control bed bugs and bed bug eggs.

The co-active ingredient, MGK-264, is an insecticide synergist that is always co-formulated with one or more active ingredients belonging to the synthetic pyrethroids and pyrethrins group. It enhances the pesticide properties of other insecticides and is registered for a wide spectrum of insect pests in or on stored food and feed, structures, companion animals, human habitat and recreational areas, human skin, clothing and proximal sites, and outdoor residential areas. For details see the Re-evaluation Decision RVD2019-10, N-Octyl bicycloheptene dicarboximide (MGK-264) And Its Associated End-use Products and the Proposed Re-evaluation Decision PRVD2017-15, N-Octyl bicycloheptene dicarboximide (MGK-264) And Its Associated End-use Products.
