Gowan's Magister SC miticide receives federal EPA registration

Gowan Company, LLC announced the Federal EPA registration of Magister SC miticide. Magister SC is registered to control mites in almonds, cherries, Christmas trees, non-bearing tree fruits, and nuts; and powdery mildew in cherries. Magister was also approved in California for almonds and cherries in January 2016.

"We are pleased to add another powerful and effective miticide to our portfolio which highlights Gowan's continuing efforts to provide our customers with solid solutions to their mite control problems," said Jairo Melgarejo, Magister SC global product manager for Gowan Company. Fenazaquin, the active ingredient in Magister SC, is a new foliar miticide belonging to the chemical class quinazoline.

Magister SC is a broad-spectrum miticide active against spider mites (Tetranychidae), broad mites (Tarsonemidae), flat mites (Tenuipalpidae), and gall mites (Eriophyidae). Magister SC provides excellent contact activity against all stages, including eggs, immature, and adult mites.

This product delivers fast knock-down along with excellent residual control for mite populations. Magister inhibits respiration in cells of target mites providing rapid control (Mitochondrial Complex I Electron Transport Inhibitor).

Magister SC is a unique miticide as it also controls powdery mildew in cherries -Podosphaera clandestine. "We are excited about the performance we have seen with this product and the opportunity it provides to control mites and fungal diseases in several important crops," said Melgarejo.

Melgarejo notes that "Although fenazaquin is a brand new compound here in the U.S., it has been used successfully on a wide range of agricultural and horticultural crops in more than 50 countries worldwide."
