Gowan Crop Protection has acquired the global rights to the active ingredient spirodiclofen. The deal with Bayer AG closed September 1, 2020. The acquisition includes product registrations and trademarks for Envidor, Envidor Speed and Ecomite.

Spirodiclofen is an IRAC Group 23 acaricide, which inhibits lipid biosynthesis in a wide spectrum of mites, including the Tetranychidae, Eriophyidae, Tenuipalpidae and Tarsonemidae families. It is active against all life stages of mites, including eggs, nymphs, and female adults, providing both an initial “knockdown” effect as well as excellent residual control. In addition, the product also controls some insect pests such as psylla (Cacopsylla pyri), scale (Lepidosaphes ulmi) and some leafhopper species.

Spirodiclofen has active registrations in many markets around the globe, primarily in horticulture crops such as citrus, apples, avocados, grapes, pears, as well as other fruit, vegetable, tree nut, and plantation crops. 

Gowan Company believes this acquisition will enhance its core product offering in tree fruits, vines, and vegetables and allow the company to serve better growers’ needs in these crops.
