Gowan Company is pleased to announce the EPA’s rescission of a cancellation order for the active ingredient spirodiclofen. This result was based on work done by Gowan’s regulatory team and included data Gowan submitted to the EPA, allowing for the completion of risk assessments and registration review decisions for spirodiclofen. In addition, this submission included Gowan’s commitment to implement label changes that adequately address the EPA’s risk concerns. As a result, Gowan has submitted an amended label for the sole end-use Envidor™ product that reflects the risk mitigation proposed by the Agency. “Gowan purchased Envidor in 2020 and went right to work providing data and working with agricultural commodity groups who need and want Envidor to defend the registration and allow continued use,” says Cindy Smith, Agriculture Relations Director for Gowan Company.
Spirodiclofen is an IRAC Group 23 acaricide that inhibits lipid biosynthesis in a wide spectrum of mites, including the Tetranychidae and Eriophyidae, Tenuipalpidae, and Tarsonemidae families. It is active against all life stages of mites, including eggs, nymphs, and female adults, providing an initial “knockdown” effect and excellent residual control. Spirodiclofen has active registrations in many horticulture crops such as tree nuts, citrus, apples, avocados, grapes, pears, and other fruit and plantation crops.
A cornerstone of Gowan’s Muddy Boots philosophy is to support growers and distribution partners in meeting the challenges of controlling destructive weeds, insects, or pathogens infesting crops. “Gowan believes the continued registration of Envidor keeps a critical residual product solution in citrus, tree nuts, tree fruits, and vines, allowing us to better serve growers’ needs in these crops,” says Eric McEwen, Director of Marketing for the US and Canada for Gowan Company.
