When you are using Annual Tree & Shrub Insect Control Concentrate on crepe myrtles, the rate is 1 fl oz per inch of the trunk diameter in 1 gallon of water. For example, if your tree is 10 inches in diameter, the rate is 10 oz. in 1 gallon of water. If you need to use more than 50 oz of product, you will mix that into 2 gallons of water.
