Using Permethrin SFR how many oz per quart water for mix of .5%?
You will need to use 1 2/3 fl. oz. for each gallon of water to get a 0.5% ratio. If you only need to mix one quart of solution at a time you will need to use just under 1/2 (0.43) oz of Permethrin SFR per quart of water to get a 0.5% mixture.
