What is the application and mix rate of Permethrin SFR for a preventative for Boring Beetles?


  The mixing ratio of Permethrin SFR 36.8% is 1 2/3 fl. oz per gallon of water. It is recommended that you spray the bark on the tree but not to the point of runoff. Permethrin will also help protect other trees from becoming infected. Please see the label for complete application instructions,
