Rotenone is a RUP (restricted use pesticide) and can only be purchased if you hold the correct applicators license. Go buy a set of pH test strips and make sure that they can read to 11.5 or higher. Keep adding hydrated lime until the pH reading is 11.5 or higher. Start with 300#, but you may have to double that or a bit more. That's why you need the test strips.
